'''The Matrix''', officially called the '''Matrix of Time''', ([[TV]]: {{cs|Mindwarp (TV story)}}, [[PROSE]]: {{cs|The Quantum Archangel (novel)}}) or sometimes the '''APC Matrix Net''', ([[PROSE]]: {{cs|The Cyber Files (novel)}}) was a [[computer|supercomputer]], a [[micro-universe]] used by the [[High Council]] of the [[Time Lord]]s as a storehouse of knowledge to predict future events, maintained by the [[Keeper of the Matrix]].


The '''Matrix''' (or '''the Matrix''') was a domain within the '''APC Net''' ('''A'''mplified '''P'''anatropic '''C'''omputer '''Net'''work), a [[computer|supercomputer]] used by the [[Time Lord]]s (specifically the [[High Council]]) both as a storehouse of knowledge and to predict future events. The terms APC Net and Matrix were often used interchangeably.
As [[TARDIS]]es possessed their own [[TARDIS matrix|matrix]], every Time Lord and TARDIS was connected to the central Matrix on Gallifrey where their experiences were constantly being uploaded. ([[COMIC]]: {{cs|Sky Jacks (comic story)}}, [[AUDIO]]: {{cs|Songs of Love (audio story)}}) For this reason, the [[Eighth Doctor]] described the Matrix as "the sum total of all Time Lord experience". ([[AUDIO]]: {{cs|Lies in Ruins (audio story)}}) {{Dhawan|c}} called it "the lived history of our race". ([[TV]]: {{cs|The Timeless Children (TV story)}})


==History==
== Characteristics ==
===Creation===
The Matrix contained a [[simulated reality environment]], once described as a "micro-universe" ([[TV]]: {{cs|The Ultimate Foe (TV story)}}) which stored the personalities of [[Time Lord]]s, now without physical bodies, and even the past ([[COMIC]]: {{cs|The Forgotten (comic story)}}) or future incarnations of living Time Lords ([[AUDIO]]: {{cs|Ascension (Gallifrey audio story)}}) within the [[APC Net]], which cross-checked the data within the Matrix. ([[AUDIO]]: {{cs|The Inquiry (audio story)}})
[[Rassilon]] entered into the Matrix after his death (or so-called "death" as understood by ancient Gallifreyan technology on Time Lord death and resurrection). Here, he and a council of [[High Evolutionary|High Evolutionaries]] or "Matrix Lords" monitored events in the outside [[universe]]. ([[DWM]]: ''[[The Tides of Time]]'' onwards) The legendary [[Dark Matrix]], however, was a repository of all the dead Time Lords' most evil thoughts. ([[PDA]]: ''[[Matrix (novel)|Matrix]]'')


===Uses of the Matrix===
As the largest [[possibility engine]] ever built, ([[AUDIO]]: {{cs|Lies in Ruins (audio story)}}) the Matrix could even store [[consciousness]]. This connection went both ways, allowing all recorded Time Lords on one occasion to be "reset" to a past data point through their [[biodata]]. ([[AUDIO]]: {{cs|Ascension (Gallifrey audio story)}}) A Time Lord could also use the Matrix to project their image onto real spacetime, or at least within a [[TARDIS]], in order to send a message. ([[AUDIO]]: {{cs|Songs of Love (audio story)}})
Returned to Gallifrey by Councillor [[Goth]], [[The Master (Tersurus)|the Master]] made secret use of the Matrix, infiltrating it and using Goth as his agent within it. Goth confronted the [[Fourth Doctor|Fourth Doctor]] there, and attempted to kill him. ([[DW]]: ''[[The Deadly Assassin]]'')


As [[Lord President]], the Doctor used the Matrix to gain access to the secrets needed to defeat the [[Sontaran]] invasion of Gallifrey, specifically the [[De-mat Gun]]. ([[DW]]: ''[[The Invasion of Time]]'') While connected to the Matrix, he learned of the existence of the [[Timewyrm]], and left a message for himself warning of this threat. ([[NA]]: ''[[Timewyrm: Genesys]]'')
Romana II explained that when connected to the Matrix, the user was outside of real [[spacetime]], "alone on the [[astral plane]]": ([[AUDIO]]: {{cs|The Inquiry (audio story)}}) it was a "null-zone" where the normal rules of the universe did not apply. Physically, the "womb"-like location was connected to the [[caldera]], but built in such a way as to take up as little real space as possible. ([[PROSE]]: {{cs|The Book of the War (novel)}}) The Matrix's physical form took the form of a "crypt" and a stone circuit board, and used [[Cloister Wraith]]s and "filed" [[Dalek]]s, [[Cyberman|Cybermen]] and [[Weeping Angel]]s attached to living "fibre optic cables" to guard the [[Cloisters]] as a "[[firewall]]". It could also ring the [[Cloister Bell]]s in the event of impending catastrophe. ([[TV]]: {{cs|Hell Bent (TV story)}}) It was the only place where new [[TARDIS|timeships]] could be constructed, or rather born; ([[PROSE]]: {{cs|The Book of the War (novel)}}) the "[[old workshop|old workshops]]" containing [[TARDIS]]es could easily be accessed from a secret passageway in the Cloisters. ([[TV]]: {{cs|Hell Bent (TV story)}})


After his supposed execution to stop Rassilon's exiled contemporary [[Omega]] from returning to the universe of [[matter]], [[Fifth Doctor|the Doctor]] hung suspended there. Omega also had access to the Matrix. ([[DW]]: ''[[Arc of Infinity (TV story)|Arc of Infinity]]'')
[[Matrix data slice]]s served as hard-drives that contained the [[virtual reality]], ([[TV]]: {{cs|Dark Water (TV story)}}) which could also be projected around individuals, described by Coordinator [[Narvin]] as immersion in the five-dimensional episodic interface of a Panoptric network. The [[Eighth Doctor]] was impressed he didn't need to wear "silly plastic glasses". ([[AUDIO]]: {{cs|The Death of Hope (audio story)}})


[[The Valeyard]] established a stronghold, the "[[Fantasy Factory]]", in the Matrix as part of his plan to steal [[Sixth Doctor|the Doctor]]'s remaining [[regeneration]]s. During his attempt to stop him, the Doctor, as well as [[The Master (Tremas)|the Master]], entered into the "dreamscape" contained therein, the latter taking [[the Master's TARDIS|his TARDIS]] (or an illusory version of it) there. The Valeyard then somehow took over the [[Keeper of the Matrix]]. ([[DW]]: ''[[The Ultimate Foe]]'')
All Time Lords were connected to the Matrix on a basic level, ([[AUDIO]]: {{cs|Pandora (audio story)}}) and the Matrix stored the memories of dead Time Lords in a framework of electrochemical cells. ([[TV]]: {{cs|The Deadly Assassin (TV story)}})


The [[Seventh Doctor|Seventh Doctor]] confronted the Dark Matrix, which was trapped inside a [[TARDIS]] as it imploded. ([[PDA]]: ''[[Matrix  (novel)|Matrix]]'')
It was not only a record of the past, but could predict the future as well ([[TV]]: {{cs|Arc of Infinity (TV story)}}) by generating prophecies out of algorithms. ([[TV]]: {{cs|Hell Bent (TV story)}})


===Fate of the Matrix===
The amount of knowledge in the Matrix, though vast, was not complete, and could be tampered with, given access. The unauthorised extraction of a Time Lord's bio-data from the Matrix was an offence tantamount to treason. ([[TV]]: {{cs|Arc of Infinity (TV story)}})
An ancient [[Gallifrey]]an evil named Pandora also survives and emerges from a special [[Wikipedia:partition (computing)|partition]] within the Matrix. Lady President [[Romana II|Romana]] was eventually able to destroy the entity by destroying the Matrix itself. ([[BFG]])


Another account says that Gallifrey was destroyed by the [[Eighth Doctor]] to prevent the voodoo cult [[Faction Paradox]] from starting a [[time war]] between the Time Lords and [[the Enemy]]. ([[EDA]]: ''[[The Ancestor Cell]]'') It was later revealed that the Time Lords had survived within the Matrix, which had then been downloaded into the Doctor's mind, although he had to sacrifice much of his memory to make space for it. Their reconstruction was possible, but would require a sufficiently advanced computer. ([[EDA]]: ''[[The Gallifrey Chronicles]]'')  
A particularly skilled person such as [[the Valeyard]] could create images of events that never had happened nor ever would. ([[TV]]: {{cs|Mindwarp (TV story)}}, {{cs|Terror of the Vervoids (TV story)}}, {{cs|The Ultimate Foe (TV story)}})


:''This event may take place in an alternative timeline or in the future, relative to the other event, given that by this time, Romana had [[regenerated]] into a [[Romana III|third incarnation]]. Possibly both they and the planet are restored at some point before Gallifrey's later destruction.''
Whenever anyone used the Matrix to acquire a specific piece of information, a safeguard would cause anything else the user accidentally stumbled across to be wiped from their minds. ([[PROSE]]: {{cs|Timewyrm: Genesys (novel)}})


==Characteristics==
If two or more incarnations of the same Time Lord accessed the Matrix simultaneously, they all gained equal access to all other incarnations' memories. Because of this, a young, pre-[[Key to Time]] version of [[Romana I]] instantly understood her future when [[Lord President|Lady President]] [[Romana II]] joined her in the Matrix. Additionally, sections of the Matrix could be partitioned, trapping entities in sections cut off from the rest of the Matrix. ([[AUDIO]]: {{cs|Lies (audio story)}})
The Matrix, specifically, contained a [[Wikipedia:simulated reality|simulated reality environment]], once described as a "micro-universe" ([[DW]]: ''[[The Ultimate Foe]]'') which served as storage for the personalites of [[Time Lord]]s now without physical bodies, and even the past incarnations of the same Time Lord. ([[IDW]]: ''[[The Forgotten]]'') Living beings could also access the Matrix. The terms Matrix and APC Net, however, have sometimes been used interchangeably.
[[File:MatrixClara.JPG|thumb|Clara watches on...([[TV]]: {{cs|The Name of the Doctor (TV story)}})]]
Following the [[Last Great Time War]], the length of the Matrix's [[database]] was eclipsed by the [[Dalek]] [[pathweb]], leading the [[Twelfth Doctor]] to identify a [[Helen Clay|unknown face]] through the latter. ([[TV]]: {{cs|Twice Upon a Time (TV story)}})


Physically, the Matrix stored the memories of dead Time Lords, storing them in a framework electrochemical cells. ([[DW]]: ''[[The Deadly Assassin]]'') It also received input from sensors contained within [[TARDIS]]es. ([[PDA]]: ''[[The Quantum Archangel]]'') The Matrix is not only a record of the past, but can actually predict the future as well. The amount of knowledge in the Matrix, though vast, is not complete, and can be tampered with if given the right amount of access. The unauthorised extraction of a Time Lord's bio-data from the Matrix is an offence tantamount to treason. ([[DW]]: ''[[Arc of Infinity (TV story)|Arc of Infinity]]'') In fact, a particularly skilled person such as [[the Valeyard]] could create images of false events that never had and never would happen. ([[DW]]: ''[[Mindwarp]]'', ''[[Terror of the Vervoids]]'', ''[[The Ultimate Foe]]'')
[[File:Arc infinity ep3.JPG|thumb|...as the [[Fifth Doctor]] combats Omega in the Matrix. ([[TV]]: {{cs|Arc of Infinity (TV story)}})]]
=== Environment ===
To living beings, the Matrix could appear like conventional reality, ([[TV]]: {{cs|The Deadly Assassin (TV story)}}, {{cs|The Ultimate Foe (TV story)}}) a surreal dream, ([[COMIC]]: {{cs|The Tides of Time (comic story)}}) a dark void with lines of light, ([[TV]]: {{cs|Arc of Infinity (TV story)}}) or first one, then the other. Physical laws were malleable to the will of the inhabitant. Experience and sheer will gave one control over "reality". For example, the [[Fourth Doctor]] shouted, "I reject it," and his wounded leg instantly healed; this was undone by a more skilled Time Lord. ([[TV]]: {{cs|The Deadly Assassin (TV story)}})


===Environment===
Beings known as the [[Matrix Lord|Matrix Lords]], including [[Rassilon]] himself, "lived" there and could direct actions in the universe. They created a physical agent, [[Shayde]], to act for them in the outside world. ([[COMIC]]: {{cs|The Tides of Time (comic story)}})
To living beings, the Matrix could appear relatively like conventional reality ([[DW]]: ''[[The Deadly Assassin]]'', ''[[The Ultimate Foe]]''), a surreal dream ([[DWM]]: ''[[The Tides of Time]]''), a dark void ([[DW]]: ''[[Arc of Infinity (TV story)|Arc of Infinity]]''), or first in one state, then giving way to another. Basic physical laws remain malleable, able to be bent or broken, according to the will of the inhabitant. The more experience with the Matrix and the greater the will of the occupant, the greater the control over the local "reality".


Beings known as the [[Matrix Lords]], including [[Rassilon]] himself, "lived" here and could direct actions from within it. For example, they created a physical agent, [[Shayde]], to act for them in the outside world. ([[DWM]]: ''[[The Tides of Time]]'')
== Physical access ==
[[File:Matrix compromised.JPG|left|thumb|The [[Cybermen]] invade the Matrix in an [[alternate timeline]]. ([[COMIC]]: {{cs|Prologue: The Sixth Doctor (comic story)}})]]
Early in [[Rassilon]]'s reign as [[Lord President]], he accessed the Matrix through a portal in the [[Great Hall of Time]]. ([[PROSE]]: {{cs|Snow White and the Seven Keys to Doomsday (DWAN short story)}})


==Physical Access==
Living beings could access the Matrix via the [[Matrix Chamber]], ([[AUDIO]]: {{cs|Neverland (audio story)}}, [[TV]]: {{cs|The Timeless Children (TV story)}}) or through the use of an apparatus connected to the user's head. ([[TV]]: {{cs|The Deadly Assassin (TV story)}}) The [[Crown of Rassilon]] worn by any [[Time Lord]] gave them instant access. ([[TV]]: {{cs|The Invasion of Time (TV story)}}) The [[Keeper of the Matrix]] held the Key of Rassilon, granting access to the [[Seventh Door]], thought legendary until the Doctor used the Key to access it. The Seventh Door allowed physical access to the Matrix. ([[TV]]: {{cs|The Ultimate Foe (TV story)}})
Access to the Matrix is obtained through an apparatus connected to or enclosing the head of the user. ([[DW]]: ''[[The Deadly Assassin]]'') The [[Crown of Rassilon]] worn by the [[Lord President|Lord or Lady President]] provides to them instant access. ([[DW]]: ''[[The Invasion of Time]]'') The [[Keeper of the Matrix]] held the Key of Rassilon that granted access to the Seventh Door, which was thought legendary until the Doctor used the Key to access it. The Seventh Door allowed physical access to the Matrix by living persons. ([[DW]]: ''[[The Ultimate Foe]]'')


{{DEFAULTSORT:Matrix}}
== Knowledge ==
Information was added to the Matrix, being imprinted on the nexus, as it was discovered by [[Time Lord]]s, ([[AUDIO]]: {{cs|The Wings of a Butterfly (audio story)}}) being organised by the recorders living within the Matrix. ([[AUDIO]]: {{cs|Neverland (audio story)}}) Additionally, all events that occurred in the [[Capitol]] were recorded in the Matrix, ([[AUDIO]]: {{cs|The Inquiry (audio story)}}) and it also received data from sensors in [[TARDIS]]es, ([[PROSE]]: {{cs|The Quantum Archangel (novel)}}) seeing through each and every TARDIS's "eyes". ([[AUDIO]]: {{cs|Songs of Love (audio story)}})
 
Many facts, figures, and formulas were contained within the Matrix, including [[faster-than-light travel]], [[anti-gravity]] power, [[dimensional transference]], ([[TV]]: {{cs|The Mysterious Planet (TV story)}}) how to build the [[De-mat Gun]], ([[TV]]: {{cs|The Invasion of Time (TV story)}}) the threat posed by the [[Timewyrm]], ([[PROSE]]: {{cs|Timewyrm: Genesys (novel)}}) [[quantum mnemonics]] from the [[pre-universe]], ([[PROSE]]: {{cs|Millennial Rites (novel)}}) the [[Spinward Corporation]] and [[Arcadia (planet)|Arcadia]] in the [[25th century]], ([[PROSE]]: {{cs|Deceit (novel)}}) [[America]] in the [[1950s]], ([[PROSE]]: {{cs|First Frontier (novel)}}) history from the [[Humanian Era|Humanian]], [[Sensorian Era|Sensorian]], [[Sumaran Era|Sumaran]], and [[Rassilon Era]]s, ([[AUDIO]]: {{cs|Neverland (audio story)}}) and the [[Sanctuary (The Golden Door)|Sanctuary]] on [[Bukol]]. ([[PROSE]]: {{cs|The Golden Door (short story)}}) During the [[Last Great Time War]], there was a Matrix file on the [[Sensorite]]s. ([[AUDIO]]: {{cs|Sphere of Influence (audio story)}})
 
Darker knowledge contained within the Matrix included the doomsday weapon on [[Uxarieus]], ([[TV]]: {{cs|Colony in Space (TV story)}}) the [[Earth]]'s [[Earth Reptile|sleeping races]], ([[TV]]: {{cs|The Sea Devils (TV story)}}) the mechanics of the [[The Source (The Keeper of Traken)|Source of Traken]], ([[TV]]: {{cs|The Keeper of Traken (TV story)}}) the location of the [[Polymos|Nestene homeworld]], ([[TV]]: {{cs|Terror of the Autons (TV story)}}) the [[Azal|name]] of the last of the [[Dæmon]]s, ([[TV]]: {{cs|The Dæmons (TV story)}}) the [[deathworm]]s, ([[TV]]: {{cs|Doctor Who (TV story)}}) the [[Crystal of Kronos]] and its relationship with the [[Chronovore]]s, ([[TV]]: {{cs|The Time Monster (TV story)}}) the army of [[Dalek]]s on [[Spiridon]], ([[TV]]: {{cs|Planet of the Daleks (TV story)}}) the [[Martian]] [[GodEngine]], ([[PROSE]]: {{cs|GodEngine (novel)}}) the [[psychic parasite]]s of [[Bellerophon]], the frozen gods of [[Volvox]], the political machinations of the [[Amentethys]], the [[Proculus]] and their offspring the [[Scerbulus]], the forgotten knowledge of the [[Kirbili]], and limited information on the [[Constructors of Destiny]] concerning the [[Midnight Cathedral]]. ([[PROSE]]: {{cs|The Quantum Archangel (novel)}})
 
There was also a section of the Matrix known as [[the Slaughterhouse]], compiled by the [[Celestial Intervention Agency]], which contained a whole armoury of theoretical weapons, including the [[Profane Virus of Rassilon]] and, in a [[parallel universe]], the [[Armageddon Sapphire]]. ([[PROSE]]: {{cs|The Quantum Archangel (novel)}})
 
The Matrix contained information on the true history of the [[Timeless Child]] and some information on [[the Division]]. However, great portions of this information were redacted even beyond {{Dhawan}}'s ability to recover. In addition, the Matrix contained the story of [[Brendan (Ascension of the Cybermen)|Brendan]], an immortal Irish policeman and an analogue for the story of the Timeless Child. It was suggested by the Master that the [[Second Tecteun]] hid Brendan's story for her child to find as a gift or an apology and a way for the Timeless Child, now [[the Doctor]], to decode the truth of their own existence. ([[TV]]: {{cs|The Timeless Children (TV story)}})
 
== History ==
=== Origins ===
According to one account, the Matrix was actually originally a part of the [[APC Net]] rather than the other way around, but over the millennia, the Matrix grew to outstrip the APC Net by far until it was the APC Net that was considered a section of the Matrix. ([[PROSE]]: {{cs|Gallifrey: A Rough Guide (short story)}})
 
[[Rassilon]] set up the Matrix in the [[Dark Times]], early in his Presidency. ([[PROSE]]: {{cs|Snow White and the Seven Keys to Doomsday (DWAN short story)}}) It was thought to be his last great invention, born out of a desire to preserve the knowledge of deceased Time Lords for future generations to consult. ([[PROSE]]: {{cs|A Brief History of Time Lords (novel)}}) According to ''[[The Book of the War]]'', [[TARDIS]]es were born in a "null-zone" connected to the [[caldera]] (the centre of the [[meta-structure of history]] at whose heart was a [[Untempered Schism|gap in time and space]]) which was usually referred to on the homeworld "as a kind of 'womb'". Because the caldera connected to all the [[thread]]s making up history, the machinery connected to it was also able to draw out data directly from "any locale which need[ed] to be monitored" and to "predict the effects of any manipulation of causality". ([[PROSE]]: {{cs|The Book of the War (novel)}}) Timeships such as [[Lolita]] and [[the Doctor's TARDIS|her sister]] referred to it as "Mother", and knew her to be a sentient entity with her own agenda.
 
In fact, Lolita believed that "Mother" had actually existed before the Great Houses, and had retconned them into existence to give herself and the timeships an origin story. Lolita's sister argued that each species' creation of the other may have occurred "simultaneously". ([[PROSE]]: {{cs|Toy Story (short story)}}) [[Christine Summerfield]] heard from [[Chris Cwej]] that his "employers" had "a computer which they used to keep track of everything they'd ever done (because, if you can move around in time, you've got to have some way of keeping everything in the right order)". In fact, "the computer was so smart that some people thought it controlled its users, not the other way round", and there were "rumours" that "the computer would have existed even without Cwej's employers, and that the machine had invented the time travellers itself, just so it could be sure that it'd be built". When she heard this story, Christine mused that the computer must have been a lot like one of the "[[All-High God|Gods]]". However, she interrupted this train of thought in her journal with a "but never mind that now" and did not return to it. ([[PROSE]]: {{cs|Dead Romance (novel)}})
 
=== Uses of the Matrix ===
After it was first set up, Rassilon used the Matrix to ask who had the power to make [[Gallifrey]] fall. ([[PROSE]]: {{cs|Snow White and the Seven Keys to Doomsday (DWAN short story)}}) The Matrix answered by foreseeing the existence of the entity known as [[the Hybrid]], a creature crossbred from two [[warrior race]]s that would one day stand in the ruins of Gallifrey and break a billion billion hearts to heal its own, unravelling the [[Web of Time]] in the process. ([[PROSE]]: {{cs|A Brief History of Time Lords (novel)}}) According to the ''[[Dalek Combat Training Manual]]'' however, the Time Lords only learnt of the [[prophecy]] of the Hybrid during the [[Cloister Wars]]. ([[PROSE]]: {{cs|Dalek Combat Training Manual (reference book)}})
 
[[The Surgeon]] once remarked that the "matrix of crystals" with which the [[Superior]]s clung onto life was one of the reasons they remained the main power of the universe during [[The Antebellum|the time before]] the [[War in Heaven]] ([[PROSE]]: {{cs|The V Cwejes (short story)}})
 
{{Delgado|c}} stole from the Matrix all the knowledge he needed to make his various schemes on [[20th century]] [[Earth]] against the [[Third Doctor]] possible. ([[PROSE]]: {{cs|The Quantum Archangel (novel)}}, {{cs|A Brief History of Time Lords (novel)}})
 
Despite the Matrix's previous [[Prophecy|prophecies]], it did not predict the [[Last Great Time War]] as possible fallout from the [[Genesis Incident]]. [[Boy (Heaven Sent)|A Time Lord]] from after the War later theorised that this was due to the conflict being too far in the future relative to the Genesis Incident for the Matrix to link the two. ([[PROSE]]: {{cs|A Brief History of Time Lords (novel)}})
 
Returned to Gallifrey by Councillor [[Goth]], {{Pratt}} used the Matrix, secretly infiltrating it and using Goth as his agent within it. Goth confronted the [[Fourth Doctor]] there and attempted to kill him. ([[TV]]: {{cs|The Deadly Assassin (TV story)}})
 
As [[President of the High Council|Lord President]], the Doctor used the Matrix to gain access to the secrets needed to defeat the [[Sontaran]] invasion of Gallifrey, specifically the [[De-mat Gun]]. ([[TV]]: {{cs|The Invasion of Time (TV story)}}) While connected to the Matrix, he learned of the existence of the [[Timewyrm]] ([[PROSE]]: {{cs|Timewyrm: Genesys (novel)}}) and [[quantum mnemonics]]. ([[PROSE]]: {{cs|Millennial Rites (novel)}})
 
After his supposed execution to stop Rassilon's exiled contemporary [[Omega]] from returning to the universe of [[matter]], the [[Fifth Doctor]] hung suspended in the Matrix. Omega also had access to the Matrix. ([[TV]]: {{cs|Arc of Infinity (TV story)}}) One of the many versions of [[Clara Oswald]] created after she entered the Doctor's [[time stream]] appeared in the Matrix and saw the Fifth Doctor when he was sent there. ([[TV]]: {{cs|The Name of the Doctor (TV story)}})
 
[[The Valeyard]] established a stronghold, the "[[Fantasy Factory]]", in the Matrix as part of his plan to steal the [[Sixth Doctor]]'s remaining [[regeneration]]s. During his attempt to stop him, the Doctor, as well as {{Ainley}}, entered into the "dreamscape" therein, the latter taking [[the Master's TARDIS|his TARDIS]] (or an illusory version of it) there. The Valeyard somehow took over the [[Keeper of the Matrix]]. ([[TV]]: {{cs|The Ultimate Foe (TV story)}})
 
The [[Seventh Doctor]] confronted the [[Dark Matrix]], which was trapped inside a [[TARDIS]] as it imploded. ([[PROSE]]: {{cs|Matrix (novel)}})
 
During the [[Last Great Time War]], the [[Eleventh General]] created the [[Dalek Combat Training Manual]] by uploading [[the Doctor]]'s various encounters with the [[Dalek]] race to a subset of the Matrix, even using the computer's processing power to extrapolate post-Time War encounters between the Doctor and the Daleks, for the Time Lord infantry to consult and be aware of the Daleks' weaknesses. ([[PROSE]]: {{cs|Dalek Combat Training Manual (reference book)}})
 
When [[the Monk]] fled the Time War, he ended up stranded up on Earth. To keep abreast on the state of the conflict, the Monk managed to rig an opening into the Matrix, feeding him up to date information on the war. ([[AUDIO]]: {{cs|Divorced, Beheaded, Regenerated (audio story)}})
 
=== Fate of the Matrix ===
An ancient [[Gallifrey]]an evil named [[Pandora]] also survived and emerged from a special [[partition]] within the Matrix. Lady President [[Romana II|Romana]] was eventually able to destroy the entity by seemingly destroying the Matrix itself. ([[AUDIO]]: {{cs|Warfare (audio story)}}) However, Romana later discovered that it had only been damaged. ([[AUDIO]]: {{cs|Ascension (Gallifrey audio story)}})
 
After Gallifrey was destroyed by the [[Eighth Doctor]] in the [[War in Heaven]], the Time Lords survived within the Matrix, which had been downloaded into the Doctor's mind - although he had to sacrifice much of his memory to make space for it. The reconstruction of the Matrix (and, thanks to it, of the Time Lords and Gallifrey) was possible, but required a sufficiently advanced computer. ([[PROSE]]: {{cs|The Gallifrey Chronicles (novel)}})
 
In a [[The Doctor's reality (Scream of the Shalka)|possible future]] for the Eighth Doctor, ([[PROSE]]: {{cs|The Tomorrow Windows (novel)}}) an [[Alien (Doctor Who - The Ninth Doctor)|alien race]] invaded Gallifrey and killed all the Time Lords, who were forced to retreat into the Matrix, whilst the [[Lord President's daughter]] was "truly [[dead]]". Only the [[Ninth Doctor (Scream of the Shalka)|Ninth Doctor]] and [[The Master (Scream of the Shalka)|the Master]], whom were responsible for "[sending] the aliens packing", remained in [[the universe]], where they were sent to sort the most [[danger]]ous [[problem]]s by the Time Lords inside the Matrix. As the Master had lost his final physical body by [[help]]ing the Doctor, the Doctor used Matrix technology to store him in a [[robot]] made out of [[TARDIS]] materials. ([[PROSE]]: {{cs|Doctor Who - The Ninth Doctor (short story)}})
 
=== Surviving the Last Great Time War ===
The Matrix disappeared with Gallifrey at the end of the Time War. ([[AUDIO]]: {{cs|Divorced, Beheaded, Regenerated (audio story)}}) However, two seemingly incompatible accounts existed as to the circumstances in which it actually survived the last day of the Time War.
 
==== The Hypothetical Gentleman ====
[[File:HalloftheMatrix.JPG|left|thumb|The Hall of the Matrix ([[COMIC]]: {{cs|Sky Jacks (comic story)}})]]
According to one account, in the final moment of the [[Last Great Time War]], the deaths of every Time Lord being uploaded to the Matrix at once allowed it to gain sentience. However, the resulting entity immediately realised it was trapped on a planet doomed to destruction, within instants. However, being connected to every TARDIS, the Matrix managed to escape its fate by uploading the entirety of itself into the one surviving Gallifreyan timeship in its reach — [[the Doctor's TARDIS]]. Having been born of innumerable deaths, the Matrix was, by the Doctor's later analysis, insane, wishing death and destruction on the rest of the universe out of spite. The Matrix intended to complete Rassilon's Final Sanction, unravelling the Web of Time and ending Creation itself, however, the TARDIS sensed its intentions through their connection and worked to keep the stowaway contained. Connected to the minds of the Doctor and his TARDIS, the Matrix remained a prisoner, scheming for centuries a way to break out into the wider universe. ([[COMIC]]: {{cs|Sky Jacks (comic story)}})
 
Exploiting the [[telepathic circuits]] of the Doctor's TARDIS, ([[COMIC]]: {{cs|Sky Jacks (comic story)}}) the Matrix projected images of a [[quantum resonator]] into [[Emily Fairfax]]'s mind, convincing her and [[Charles Fairfax|her husband]] that she was being contacted by an angel. After the pair built the machine, the Matrix linked it to the TARDIS to power it. The Matrix, now in humanoid form, emerged from the machine to find a police officer, whom he sucked the time out of, leaving him frozen in time. The [[Eleventh Doctor]] witnessed this and decided to investigate the machine's power source. The Hypothetical Gentleman, as dubbed by the Doctor as he mistakenly believed the "man" had come from a hypothetical universe linked to by the quantum resonator, then proceeded to suck out the time from [[Rory Williams]]. When the [[telepathic]] Emily read the Gentleman's mind, it was filled with images of [[Sontaran]]s, a [[Peg doll (Night Terrors)|peg doll]], a [[Zygon]], a [[Kroton (species)|Kroton]], a [[Headless Monk]], a [[Silent]], a [[Weeping Angel]], and a [[Krynoid]].
 
He subsequently sucked the time out of Charles, deeming the meal, "an insufficient morsel", and then disappeared. The Doctor was examining the victims, when he returned, and the Doctor him about how he could write in [[High Gallifreyan]]. The Gentleman didn't provide an answer, and instead taunted the Doctor with the unknown knowledge. He then promptly began to steal the Doctor's time, which would have given him his own reality, but [[Amy Pond]] smashed the quantum resonator, apparently sucking him back into his hypothetical world and freeing all his victims. As the Doctor, Amy, and Rory tried to leave in the TARDIS, the control panel sparked, surprising the Doctor, and he described it as the TARDIS having an upset tummy, and that it was nothing to worry about. In truth, the Hypothetical Gentleman had been returned to the TARDIS and its presence continued to upset the timeship. ([[COMIC]]: {{cs|Hypothetical Gentleman (comic story)}})
 
The Matrix attempted to fight the Doctor's TARDIS for control of its systems, and succeeded in taking control of one the TARDIS's old console rooms. From there, the Matrix programmed the creation of a large and featureless room featuring a copy of the TARDIS's outer police box shell, thereby manipulating the Doctor into believing he had left the TARDIS when he walked out of those doors. The Matrix then took control of the TARDIS's power source, the [[Eye of Harmony]]. Using the Eye's power, the Matrix created a wormhole to escape into the wider universe. However, the TARDIS retaliated by expanding the console room controlled by the Matrix to massive size, making it so absurdly big that it contained an entire "sky world". This process, which the Matrix could not stop, diverted enough energy from the Eye that the Matrix could no longer use any for its own purposes.
 
[[File:Sentient Matrix.jpg|right|thumb|The Sentient Matrix opposes the Eleventh Doctor. ([[COMIC]]: {{cs|Sky Jacks (comic story)}})]]
The wormhole, running in the direction opposite to that wished by the Matrix, drew in aircrafts and starships from various points in space and time and trapped them inside the "sky world", alongside the Matrix itself as well as he Doctor and his companion [[Clara Oswald]]. While in the sky world, the Matrix built itself several spider-like robotic bodies, as well as an army of [[pterodactyl]]-like robots, out of the scrap metal provided by the various crashed spaceships. Just as it seemed to make its escape using an [[atomic bomb]] brought to the sky world in the American aeroplane ''[[Sky Jack]]'', the Matrix was stopped by the Doctor, who trapped the mad intelligence forever by connecting both ends of the wormhole together into an ouroboros shape. ([[COMIC]]: {{cs|Sky Jacks (comic story)}})
 
==== The Matrix on Gallifrey ====
According to another account which the [[Twelfth Doctor]] claimed was the result of rewriting history, ([[PROSE]]: {{Cs|Big Bang Generation (novel)|Big Bang Generation}}) [[Gallifrey]] and the [[Time Lord]]s were not actually destroyed by [[the Moment]], despite the widespread belief of the rest of the universe; the planet had instead been placed, Matrix and all, into [[Gallifrey's pocket universe|a pocket universe]], hidden but unharmed. ([[TV]]: {{cs|The Day of the Doctor (TV story)}}) Scanning for [[N-Space]], the Matrix discovered the [[time field]], giving the Time Lords an opening through which to broadcast [[the Question]]. ([[PROSE]]: {{cs|A Brief History of Time Lords (novel)}}) After Gallifrey returned to the universe, the [[Twelfth Doctor]] found the Matrix where he remembered it from his childhood, below the [[Capitol]], accessible the [[Cloisters]]. An imprisoned [[Dalek (Hell Bent)|Dalek]] encountered by the Doctor and [[Clara Oswald]] on their way to the Matrix seemed to the Doctor to have been there since the [[Cloister Wars]]. ([[TV]]: {{cs|Hell Bent (TV story)}})
 
Some time later, {{Simm}}, sent back to Gallifrey just prior to its supposed destruction, spent some time in a Gallifreyan hospital before leaving the planet in what the renegade later described as a "mutual kicking me out". Having therefore recently visited Gallifrey, the Master's next incarnation, [[Missy]], ([[TV]]: {{cs|The Doctor Falls (TV story)}}) was able to use a [[Matrix data slice]] to store the minds of the recently deceased into a [[data cloud]] so that the emotions could be altered and upgraded once their minds were downloaded back into [[Cyber-conversion|converted]] [[Cyberman|Cybermen]]. ([[TV]]: {{cs|Dark Water (TV story)}}, {{cs|Death in Heaven (TV story)}})
 
In order to find out about the [[Testimony Foundation]], the Twelfth Doctor suggested using the Matrix on Gallifrey. However, he decided instead to use the [[Dalek]] [[Pathweb]] through [[Rusty (Into the Dalek)|Rusty]] as they needed something bigger than the Matrix. ([[TV]]: {{cs|Twice Upon a Time (TV story)}})
 
At some point after the events on the [[Mondasian]] [[Colony ship (World Enough and Time)|colony ship]], ([[TV]]: {{cs|World Enough and Time (TV story)}}, {{cs|The Doctor Falls (TV story)}}) {{Dhawan}} returned to Gallifrey where he began playing around and hacking into the Matrix. The Master got lost inside before he found "everything" and later told the [[Cyberium]] that he "ransacked" the Matrix and as a result, had all of the knowledge of the Time Lords inside his head. What the Master learned from the Matrix about the [[Timeless Child]] and the truth about the Time Lords' history caused him to ravage Gallifrey. ([[TV]]: {{cs|Spyfall (TV story)}}, {{cs|The Timeless Children (TV story)}})
 
After returning to the ruins of Gallifrey with the [[Thirteenth Doctor]], the Master revealed that he left the Matrix intact when he destroyed everything else. The Master used the Matrix to show the Doctor the truth about the Timeless Child, [[Tecteun]] and the Time Lords, but revealed that large portions of the Matrix's data relating to the life of the Timeless Child - in reality the forgotten past of the Doctor - and [[the Division]] had been erased even beyond the Master's ability to recover despite the fact that it had taken up a lot of space in the Matrix. The Master suggested that the images of [[Brendan (Ascension of the Cybermen)|Brendan]], the disguised true story of the Timeless Child which he had transmitted into the Doctor's mind, were purposefully left behind by Tecteun as a gift or apology to her child, possibly as a way to decode and learn the truth about their past.
 
After revealing his new race of [[CyberMaster]]s, the Master then trapped the Doctor inside the Matrix. Guided by a [[Matrix projection]] of [[Fugitive Doctor|a forgotten incarnation]], the Doctor overloaded the Matrix with a blast of her memories, forcing it to release her.

You may wish to consult Matrix (disambiguation) for other, similarly-named pages.

The Matrix, officially called the Matrix of Time, (TV: Mindwarp [+]Loading...["Mindwarp (TV story)"], PROSE: The Quantum Archangel [+]Loading...["The Quantum Archangel (novel)"]) or sometimes the APC Matrix Net, (PROSE: The Cyber Files [+]Loading...["The Cyber Files (novel)"]) was a supercomputer, a micro-universe used by the High Council of the Time Lords as a storehouse of knowledge to predict future events, maintained by the Keeper of the Matrix.

As TARDISes possessed their own matrix, every Time Lord and TARDIS was connected to the central Matrix on Gallifrey where their experiences were constantly being uploaded. (COMIC: Sky Jacks [+]Loading...["Sky Jacks (comic story)"], AUDIO: Songs of Love [+]Loading...["Songs of Love (audio story)"]) For this reason, the Eighth Doctor described the Matrix as "the sum total of all Time Lord experience". (AUDIO: Lies in Ruins [+]Loading...["Lies in Ruins (audio story)"]) The Spy Master called it "the lived history of our race". (TV: The Timeless Children [+]Loading...["The Timeless Children (TV story)"])

Characteristics[[edit] | [edit source]]

The Matrix contained a simulated reality environment, once described as a "micro-universe" (TV: The Ultimate Foe [+]Loading...["The Ultimate Foe (TV story)"]) which stored the personalities of Time Lords, now without physical bodies, and even the past (COMIC: The Forgotten [+]Loading...["The Forgotten (comic story)"]) or future incarnations of living Time Lords (AUDIO: Ascension [+]Loading...["Ascension (Gallifrey audio story)"]) within the APC Net, which cross-checked the data within the Matrix. (AUDIO: The Inquiry [+]Loading...["The Inquiry (audio story)"])

As the largest possibility engine ever built, (AUDIO: Lies in Ruins [+]Loading...["Lies in Ruins (audio story)"]) the Matrix could even store consciousness. This connection went both ways, allowing all recorded Time Lords on one occasion to be "reset" to a past data point through their biodata. (AUDIO: Ascension [+]Loading...["Ascension (Gallifrey audio story)"]) A Time Lord could also use the Matrix to project their image onto real spacetime, or at least within a TARDIS, in order to send a message. (AUDIO: Songs of Love [+]Loading...["Songs of Love (audio story)"])

Romana II explained that when connected to the Matrix, the user was outside of real spacetime, "alone on the astral plane": (AUDIO: The Inquiry [+]Loading...["The Inquiry (audio story)"]) it was a "null-zone" where the normal rules of the universe did not apply. Physically, the "womb"-like location was connected to the caldera, but built in such a way as to take up as little real space as possible. (PROSE: The Book of the War [+]Loading...["The Book of the War (novel)"]) The Matrix's physical form took the form of a "crypt" and a stone circuit board, and used Cloister Wraiths and "filed" Daleks, Cybermen and Weeping Angels attached to living "fibre optic cables" to guard the Cloisters as a "firewall". It could also ring the Cloister Bells in the event of impending catastrophe. (TV: Hell Bent [+]Loading...["Hell Bent (TV story)"]) It was the only place where new timeships could be constructed, or rather born; (PROSE: The Book of the War [+]Loading...["The Book of the War (novel)"]) the "old workshops" containing TARDISes could easily be accessed from a secret passageway in the Cloisters. (TV: Hell Bent [+]Loading...["Hell Bent (TV story)"])

Matrix data slices served as hard-drives that contained the virtual reality, (TV: Dark Water [+]Loading...["Dark Water (TV story)"]) which could also be projected around individuals, described by Coordinator Narvin as immersion in the five-dimensional episodic interface of a Panoptric network. The Eighth Doctor was impressed he didn't need to wear "silly plastic glasses". (AUDIO: The Death of Hope [+]Loading...["The Death of Hope (audio story)"])

All Time Lords were connected to the Matrix on a basic level, (AUDIO: Pandora [+]Loading...["Pandora (audio story)"]) and the Matrix stored the memories of dead Time Lords in a framework of electrochemical cells. (TV: The Deadly Assassin [+]Loading...["The Deadly Assassin (TV story)"])

It was not only a record of the past, but could predict the future as well (TV: Arc of Infinity [+]Loading...["Arc of Infinity (TV story)"]) by generating prophecies out of algorithms. (TV: Hell Bent [+]Loading...["Hell Bent (TV story)"])

The amount of knowledge in the Matrix, though vast, was not complete, and could be tampered with, given access. The unauthorised extraction of a Time Lord's bio-data from the Matrix was an offence tantamount to treason. (TV: Arc of Infinity [+]Loading...["Arc of Infinity (TV story)"])

A particularly skilled person such as the Valeyard could create images of events that never had happened nor ever would. (TV: Mindwarp [+]Loading...["Mindwarp (TV story)"], Terror of the Vervoids [+]Loading...["Terror of the Vervoids (TV story)"], The Ultimate Foe [+]Loading...["The Ultimate Foe (TV story)"])

Whenever anyone used the Matrix to acquire a specific piece of information, a safeguard would cause anything else the user accidentally stumbled across to be wiped from their minds. (PROSE: Timewyrm: Genesys [+]Loading...["Timewyrm: Genesys (novel)"])

If two or more incarnations of the same Time Lord accessed the Matrix simultaneously, they all gained equal access to all other incarnations' memories. Because of this, a young, pre-Key to Time version of Romana I instantly understood her future when Lady President Romana II joined her in the Matrix. Additionally, sections of the Matrix could be partitioned, trapping entities in sections cut off from the rest of the Matrix. (AUDIO: Lies [+]Loading...["Lies (audio story)"])

Clara watches on...(TV: The Name of the Doctor [+]Loading...["The Name of the Doctor (TV story)"])

Following the Last Great Time War, the length of the Matrix's database was eclipsed by the Dalek pathweb, leading the Twelfth Doctor to identify a unknown face through the latter. (TV: Twice Upon a Time [+]Loading...["Twice Upon a Time (TV story)"])

Environment[[edit] | [edit source]]

To living beings, the Matrix could appear like conventional reality, (TV: The Deadly Assassin [+]Loading...["The Deadly Assassin (TV story)"], The Ultimate Foe [+]Loading...["The Ultimate Foe (TV story)"]) a surreal dream, (COMIC: The Tides of Time [+]Loading...["The Tides of Time (comic story)"]) a dark void with lines of light, (TV: Arc of Infinity [+]Loading...["Arc of Infinity (TV story)"]) or first one, then the other. Physical laws were malleable to the will of the inhabitant. Experience and sheer will gave one control over "reality". For example, the Fourth Doctor shouted, "I reject it," and his wounded leg instantly healed; this was undone by a more skilled Time Lord. (TV: The Deadly Assassin [+]Loading...["The Deadly Assassin (TV story)"])

Beings known as the Matrix Lords, including Rassilon himself, "lived" there and could direct actions in the universe. They created a physical agent, Shayde, to act for them in the outside world. (COMIC: The Tides of Time [+]Loading...["The Tides of Time (comic story)"])

Physical access[[edit] | [edit source]]

The Cybermen invade the Matrix in an alternate timeline. (COMIC: Prologue: The Sixth Doctor [+]Loading...["Prologue: The Sixth Doctor (comic story)"])

Early in Rassilon's reign as Lord President, he accessed the Matrix through a portal in the Great Hall of Time. (PROSE: Snow White and the Seven Keys to Doomsday [+]Loading...["Snow White and the Seven Keys to Doomsday (DWAN short story)"])

Living beings could access the Matrix via the Matrix Chamber, (AUDIO: Neverland [+]Loading...["Neverland (audio story)"], TV: The Timeless Children [+]Loading...["The Timeless Children (TV story)"]) or through the use of an apparatus connected to the user's head. (TV: The Deadly Assassin [+]Loading...["The Deadly Assassin (TV story)"]) The Crown of Rassilon worn by any Time Lord gave them instant access. (TV: The Invasion of Time [+]Loading...["The Invasion of Time (TV story)"]) The Keeper of the Matrix held the Key of Rassilon, granting access to the Seventh Door, thought legendary until the Doctor used the Key to access it. The Seventh Door allowed physical access to the Matrix. (TV: The Ultimate Foe [+]Loading...["The Ultimate Foe (TV story)"])

Knowledge[[edit] | [edit source]]

Information was added to the Matrix, being imprinted on the nexus, as it was discovered by Time Lords, (AUDIO: The Wings of a Butterfly [+]Loading...["The Wings of a Butterfly (audio story)"]) being organised by the recorders living within the Matrix. (AUDIO: Neverland [+]Loading...["Neverland (audio story)"]) Additionally, all events that occurred in the Capitol were recorded in the Matrix, (AUDIO: The Inquiry [+]Loading...["The Inquiry (audio story)"]) and it also received data from sensors in TARDISes, (PROSE: The Quantum Archangel [+]Loading...["The Quantum Archangel (novel)"]) seeing through each and every TARDIS's "eyes". (AUDIO: Songs of Love [+]Loading...["Songs of Love (audio story)"])

Many facts, figures, and formulas were contained within the Matrix, including faster-than-light travel, anti-gravity power, dimensional transference, (TV: The Mysterious Planet [+]Loading...["The Mysterious Planet (TV story)"]) how to build the De-mat Gun, (TV: The Invasion of Time [+]Loading...["The Invasion of Time (TV story)"]) the threat posed by the Timewyrm, (PROSE: Timewyrm: Genesys [+]Loading...["Timewyrm: Genesys (novel)"]) quantum mnemonics from the pre-universe, (PROSE: Millennial Rites [+]Loading...["Millennial Rites (novel)"]) the Spinward Corporation and Arcadia in the 25th century, (PROSE: Deceit [+]Loading...["Deceit (novel)"]) America in the 1950s, (PROSE: First Frontier [+]Loading...["First Frontier (novel)"]) history from the Humanian, Sensorian, Sumaran, and Rassilon Eras, (AUDIO: Neverland [+]Loading...["Neverland (audio story)"]) and the Sanctuary on Bukol. (PROSE: The Golden Door [+]Loading...["The Golden Door (short story)"]) During the Last Great Time War, there was a Matrix file on the Sensorites. (AUDIO: Sphere of Influence [+]Loading...["Sphere of Influence (audio story)"])

Darker knowledge contained within the Matrix included the doomsday weapon on Uxarieus, (TV: Colony in Space [+]Loading...["Colony in Space (TV story)"]) the Earth's sleeping races, (TV: The Sea Devils [+]Loading...["The Sea Devils (TV story)"]) the mechanics of the Source of Traken, (TV: The Keeper of Traken [+]Loading...["The Keeper of Traken (TV story)"]) the location of the Nestene homeworld, (TV: Terror of the Autons [+]Loading...["Terror of the Autons (TV story)"]) the name of the last of the Dæmons, (TV: The Dæmons [+]Loading...["The Dæmons (TV story)"]) the deathworms, (TV: Doctor Who [+]Loading...["Doctor Who (TV story)"]) the Crystal of Kronos and its relationship with the Chronovores, (TV: The Time Monster [+]Loading...["The Time Monster (TV story)"]) the army of Daleks on Spiridon, (TV: Planet of the Daleks [+]Loading...["Planet of the Daleks (TV story)"]) the Martian GodEngine, (PROSE: GodEngine [+]Loading...["GodEngine (novel)"]) the psychic parasites of Bellerophon, the frozen gods of Volvox, the political machinations of the Amentethys, the Proculus and their offspring the Scerbulus, the forgotten knowledge of the Kirbili, and limited information on the Constructors of Destiny concerning the Midnight Cathedral. (PROSE: The Quantum Archangel [+]Loading...["The Quantum Archangel (novel)"])

There was also a section of the Matrix known as the Slaughterhouse, compiled by the Celestial Intervention Agency, which contained a whole armoury of theoretical weapons, including the Profane Virus of Rassilon and, in a parallel universe, the Armageddon Sapphire. (PROSE: The Quantum Archangel [+]Loading...["The Quantum Archangel (novel)"])

The Matrix contained information on the true history of the Timeless Child and some information on the Division. However, great portions of this information were redacted even beyond the Spy Master's ability to recover. In addition, the Matrix contained the story of Brendan, an immortal Irish policeman and an analogue for the story of the Timeless Child. It was suggested by the Master that the Second Tecteun hid Brendan's story for her child to find as a gift or an apology and a way for the Timeless Child, now the Doctor, to decode the truth of their own existence. (TV: The Timeless Children [+]Loading...["The Timeless Children (TV story)"])

History[[edit] | [edit source]]

Origins[[edit] | [edit source]]

According to one account, the Matrix was actually originally a part of the APC Net rather than the other way around, but over the millennia, the Matrix grew to outstrip the APC Net by far until it was the APC Net that was considered a section of the Matrix. (PROSE: Gallifrey: A Rough Guide [+]Loading...["Gallifrey: A Rough Guide (short story)"])

Rassilon set up the Matrix in the Dark Times, early in his Presidency. (PROSE: Snow White and the Seven Keys to Doomsday [+]Loading...["Snow White and the Seven Keys to Doomsday (DWAN short story)"]) It was thought to be his last great invention, born out of a desire to preserve the knowledge of deceased Time Lords for future generations to consult. (PROSE: A Brief History of Time Lords [+]Loading...["A Brief History of Time Lords (novel)"]) According to The Book of the War, TARDISes were born in a "null-zone" connected to the caldera (the centre of the meta-structure of history at whose heart was a gap in time and space) which was usually referred to on the homeworld "as a kind of 'womb'". Because the caldera connected to all the threads making up history, the machinery connected to it was also able to draw out data directly from "any locale which need[ed] to be monitored" and to "predict the effects of any manipulation of causality". (PROSE: The Book of the War [+]Loading...["The Book of the War (novel)"]) Timeships such as Lolita and her sister referred to it as "Mother", and knew her to be a sentient entity with her own agenda.

In fact, Lolita believed that "Mother" had actually existed before the Great Houses, and had retconned them into existence to give herself and the timeships an origin story. Lolita's sister argued that each species' creation of the other may have occurred "simultaneously". (PROSE: Toy Story [+]Loading...["Toy Story (short story)"]) Christine Summerfield heard from Chris Cwej that his "employers" had "a computer which they used to keep track of everything they'd ever done (because, if you can move around in time, you've got to have some way of keeping everything in the right order)". In fact, "the computer was so smart that some people thought it controlled its users, not the other way round", and there were "rumours" that "the computer would have existed even without Cwej's employers, and that the machine had invented the time travellers itself, just so it could be sure that it'd be built". When she heard this story, Christine mused that the computer must have been a lot like one of the "Gods". However, she interrupted this train of thought in her journal with a "but never mind that now" and did not return to it. (PROSE: Dead Romance [+]Loading...["Dead Romance (novel)"])

Uses of the Matrix[[edit] | [edit source]]

After it was first set up, Rassilon used the Matrix to ask who had the power to make Gallifrey fall. (PROSE: Snow White and the Seven Keys to Doomsday [+]Loading...["Snow White and the Seven Keys to Doomsday (DWAN short story)"]) The Matrix answered by foreseeing the existence of the entity known as the Hybrid, a creature crossbred from two warrior races that would one day stand in the ruins of Gallifrey and break a billion billion hearts to heal its own, unravelling the Web of Time in the process. (PROSE: A Brief History of Time Lords [+]Loading...["A Brief History of Time Lords (novel)"]) According to the Dalek Combat Training Manual however, the Time Lords only learnt of the prophecy of the Hybrid during the Cloister Wars. (PROSE: Dalek Combat Training Manual [+]Loading...["Dalek Combat Training Manual (reference book)"])

The Surgeon once remarked that the "matrix of crystals" with which the Superiors clung onto life was one of the reasons they remained the main power of the universe during the time before the War in Heaven (PROSE: The V Cwejes [+]Loading...["The V Cwejes (short story)"])

The Master stole from the Matrix all the knowledge he needed to make his various schemes on 20th century Earth against the Third Doctor possible. (PROSE: The Quantum Archangel [+]Loading...["The Quantum Archangel (novel)"], A Brief History of Time Lords [+]Loading...["A Brief History of Time Lords (novel)"])

Despite the Matrix's previous prophecies, it did not predict the Last Great Time War as possible fallout from the Genesis Incident. A Time Lord from after the War later theorised that this was due to the conflict being too far in the future relative to the Genesis Incident for the Matrix to link the two. (PROSE: A Brief History of Time Lords [+]Loading...["A Brief History of Time Lords (novel)"])

Returned to Gallifrey by Councillor Goth, the Decayed Master used the Matrix, secretly infiltrating it and using Goth as his agent within it. Goth confronted the Fourth Doctor there and attempted to kill him. (TV: The Deadly Assassin [+]Loading...["The Deadly Assassin (TV story)"])

As Lord President, the Doctor used the Matrix to gain access to the secrets needed to defeat the Sontaran invasion of Gallifrey, specifically the De-mat Gun. (TV: The Invasion of Time [+]Loading...["The Invasion of Time (TV story)"]) While connected to the Matrix, he learned of the existence of the Timewyrm (PROSE: Timewyrm: Genesys [+]Loading...["Timewyrm: Genesys (novel)"]) and quantum mnemonics. (PROSE: Millennial Rites [+]Loading...["Millennial Rites (novel)"])

After his supposed execution to stop Rassilon's exiled contemporary Omega from returning to the universe of matter, the Fifth Doctor hung suspended in the Matrix. Omega also had access to the Matrix. (TV: Arc of Infinity [+]Loading...["Arc of Infinity (TV story)"]) One of the many versions of Clara Oswald created after she entered the Doctor's time stream appeared in the Matrix and saw the Fifth Doctor when he was sent there. (TV: The Name of the Doctor [+]Loading...["The Name of the Doctor (TV story)"])

The Valeyard established a stronghold, the "Fantasy Factory", in the Matrix as part of his plan to steal the Sixth Doctor's remaining regenerations. During his attempt to stop him, the Doctor, as well as the Tremas Master, entered into the "dreamscape" therein, the latter taking his TARDIS (or an illusory version of it) there. The Valeyard somehow took over the Keeper of the Matrix. (TV: The Ultimate Foe [+]Loading...["The Ultimate Foe (TV story)"])

The Seventh Doctor confronted the Dark Matrix, which was trapped inside a TARDIS as it imploded. (PROSE: Matrix [+]Loading...["Matrix (novel)"])

During the Last Great Time War, the Eleventh General created the Dalek Combat Training Manual by uploading the Doctor's various encounters with the Dalek race to a subset of the Matrix, even using the computer's processing power to extrapolate post-Time War encounters between the Doctor and the Daleks, for the Time Lord infantry to consult and be aware of the Daleks' weaknesses. (PROSE: Dalek Combat Training Manual [+]Loading...["Dalek Combat Training Manual (reference book)"])

When the Monk fled the Time War, he ended up stranded up on Earth. To keep abreast on the state of the conflict, the Monk managed to rig an opening into the Matrix, feeding him up to date information on the war. (AUDIO: Divorced, Beheaded, Regenerated [+]Loading...["Divorced, Beheaded, Regenerated (audio story)"])

Fate of the Matrix[[edit] | [edit source]]

An ancient Gallifreyan evil named Pandora also survived and emerged from a special partition within the Matrix. Lady President Romana was eventually able to destroy the entity by seemingly destroying the Matrix itself. (AUDIO: Warfare [+]Loading...["Warfare (audio story)"]) However, Romana later discovered that it had only been damaged. (AUDIO: Ascension [+]Loading...["Ascension (Gallifrey audio story)"])

After Gallifrey was destroyed by the Eighth Doctor in the War in Heaven, the Time Lords survived within the Matrix, which had been downloaded into the Doctor's mind - although he had to sacrifice much of his memory to make space for it. The reconstruction of the Matrix (and, thanks to it, of the Time Lords and Gallifrey) was possible, but required a sufficiently advanced computer. (PROSE: The Gallifrey Chronicles [+]Loading...["The Gallifrey Chronicles (novel)"])

In a possible future for the Eighth Doctor, (PROSE: The Tomorrow Windows [+]Loading...["The Tomorrow Windows (novel)"]) an alien race invaded Gallifrey and killed all the Time Lords, who were forced to retreat into the Matrix, whilst the Lord President's daughter was "truly dead". Only the Ninth Doctor and the Master, whom were responsible for "[sending] the aliens packing", remained in the universe, where they were sent to sort the most dangerous problems by the Time Lords inside the Matrix. As the Master had lost his final physical body by helping the Doctor, the Doctor used Matrix technology to store him in a robot made out of TARDIS materials. (PROSE: Doctor Who - The Ninth Doctor [+]Loading...["Doctor Who - The Ninth Doctor (short story)"])

Surviving the Last Great Time War[[edit] | [edit source]]

The Matrix disappeared with Gallifrey at the end of the Time War. (AUDIO: Divorced, Beheaded, Regenerated [+]Loading...["Divorced, Beheaded, Regenerated (audio story)"]) However, two seemingly incompatible accounts existed as to the circumstances in which it actually survived the last day of the Time War.

The Hypothetical Gentleman[[edit] | [edit source]]

The Hall of the Matrix (COMIC: Sky Jacks [+]Loading...["Sky Jacks (comic story)"])

According to one account, in the final moment of the Last Great Time War, the deaths of every Time Lord being uploaded to the Matrix at once allowed it to gain sentience. However, the resulting entity immediately realised it was trapped on a planet doomed to destruction, within instants. However, being connected to every TARDIS, the Matrix managed to escape its fate by uploading the entirety of itself into the one surviving Gallifreyan timeship in its reach — the Doctor's TARDIS. Having been born of innumerable deaths, the Matrix was, by the Doctor's later analysis, insane, wishing death and destruction on the rest of the universe out of spite. The Matrix intended to complete Rassilon's Final Sanction, unravelling the Web of Time and ending Creation itself, however, the TARDIS sensed its intentions through their connection and worked to keep the stowaway contained. Connected to the minds of the Doctor and his TARDIS, the Matrix remained a prisoner, scheming for centuries a way to break out into the wider universe. (COMIC: Sky Jacks [+]Loading...["Sky Jacks (comic story)"])

Exploiting the telepathic circuits of the Doctor's TARDIS, (COMIC: Sky Jacks [+]Loading...["Sky Jacks (comic story)"]) the Matrix projected images of a quantum resonator into Emily Fairfax's mind, convincing her and her husband that she was being contacted by an angel. After the pair built the machine, the Matrix linked it to the TARDIS to power it. The Matrix, now in humanoid form, emerged from the machine to find a police officer, whom he sucked the time out of, leaving him frozen in time. The Eleventh Doctor witnessed this and decided to investigate the machine's power source. The Hypothetical Gentleman, as dubbed by the Doctor as he mistakenly believed the "man" had come from a hypothetical universe linked to by the quantum resonator, then proceeded to suck out the time from Rory Williams. When the telepathic Emily read the Gentleman's mind, it was filled with images of Sontarans, a peg doll, a Zygon, a Kroton, a Headless Monk, a Silent, a Weeping Angel, and a Krynoid.

He subsequently sucked the time out of Charles, deeming the meal, "an insufficient morsel", and then disappeared. The Doctor was examining the victims, when he returned, and the Doctor him about how he could write in High Gallifreyan. The Gentleman didn't provide an answer, and instead taunted the Doctor with the unknown knowledge. He then promptly began to steal the Doctor's time, which would have given him his own reality, but Amy Pond smashed the quantum resonator, apparently sucking him back into his hypothetical world and freeing all his victims. As the Doctor, Amy, and Rory tried to leave in the TARDIS, the control panel sparked, surprising the Doctor, and he described it as the TARDIS having an upset tummy, and that it was nothing to worry about. In truth, the Hypothetical Gentleman had been returned to the TARDIS and its presence continued to upset the timeship. (COMIC: Hypothetical Gentleman [+]Loading...["Hypothetical Gentleman (comic story)"])

The Matrix attempted to fight the Doctor's TARDIS for control of its systems, and succeeded in taking control of one the TARDIS's old console rooms. From there, the Matrix programmed the creation of a large and featureless room featuring a copy of the TARDIS's outer police box shell, thereby manipulating the Doctor into believing he had left the TARDIS when he walked out of those doors. The Matrix then took control of the TARDIS's power source, the Eye of Harmony. Using the Eye's power, the Matrix created a wormhole to escape into the wider universe. However, the TARDIS retaliated by expanding the console room controlled by the Matrix to massive size, making it so absurdly big that it contained an entire "sky world". This process, which the Matrix could not stop, diverted enough energy from the Eye that the Matrix could no longer use any for its own purposes.

The Sentient Matrix opposes the Eleventh Doctor. (COMIC: Sky Jacks [+]Loading...["Sky Jacks (comic story)"])

The wormhole, running in the direction opposite to that wished by the Matrix, drew in aircrafts and starships from various points in space and time and trapped them inside the "sky world", alongside the Matrix itself as well as he Doctor and his companion Clara Oswald. While in the sky world, the Matrix built itself several spider-like robotic bodies, as well as an army of pterodactyl-like robots, out of the scrap metal provided by the various crashed spaceships. Just as it seemed to make its escape using an atomic bomb brought to the sky world in the American aeroplane Sky Jack, the Matrix was stopped by the Doctor, who trapped the mad intelligence forever by connecting both ends of the wormhole together into an ouroboros shape.

The Matrix on Gallifrey[[edit] | [edit source]]

According to another account which the Twelfth Doctor claimed was the result of rewriting history, (PROSE: Big Bang Generation [+]Loading...["Big Bang Generation (novel)","Big Bang Generation"]) Gallifrey and the Time Lords were not actually destroyed by the Moment, despite the widespread belief of the rest of the universe; the planet had instead been placed, Matrix and all, into a pocket universe, hidden but unharmed. (TV: The Day of the Doctor [+]Loading...["The Day of the Doctor (TV story)"]) Scanning for N-Space, the Matrix discovered the time field, giving the Time Lords an opening through which to broadcast the Question. (PROSE: A Brief History of Time Lords [+]Loading...["A Brief History of Time Lords (novel)"]) After Gallifrey returned to the universe, the Twelfth Doctor found the Matrix where he remembered it from his childhood, below the Capitol, accessible the Cloisters. An imprisoned Dalek encountered by the Doctor and Clara Oswald on their way to the Matrix seemed to the Doctor to have been there since the Cloister Wars. (TV: Hell Bent [+]Loading...["Hell Bent (TV story)"])

Some time later, the Saxon Master, sent back to Gallifrey just prior to its supposed destruction, spent some time in a Gallifreyan hospital before leaving the planet in what the renegade later described as a "mutual kicking me out". Having therefore recently visited Gallifrey, the Master's next incarnation, Missy, (TV: The Doctor Falls [+]Loading...["The Doctor Falls (TV story)"]) was able to use a Matrix data slice to store the minds of the recently deceased into a data cloud so that the emotions could be altered and upgraded once their minds were downloaded back into converted Cybermen. (TV: Dark Water [+]Loading...["Dark Water (TV story)"], Death in Heaven [+]Loading...["Death in Heaven (TV story)"])

In order to find out about the Testimony Foundation, the Twelfth Doctor suggested using the Matrix on Gallifrey. However, he decided instead to use the Dalek Pathweb through Rusty as they needed something bigger than the Matrix. (TV: Twice Upon a Time [+]Loading...["Twice Upon a Time (TV story)"])

At some point after the events on the Mondasian colony ship, (TV: World Enough and Time [+]Loading...["World Enough and Time (TV story)"], The Doctor Falls [+]Loading...["The Doctor Falls (TV story)"]) the Spy Master returned to Gallifrey where he began playing around and hacking into the Matrix. The Master got lost inside before he found "everything" and later told the Cyberium that he "ransacked" the Matrix and as a result, had all of the knowledge of the Time Lords inside his head. What the Master learned from the Matrix about the Timeless Child and the truth about the Time Lords' history caused him to ravage Gallifrey. (TV: Spyfall [+]Loading...["Spyfall (TV story)"], The Timeless Children [+]Loading...["The Timeless Children (TV story)"])

After returning to the ruins of Gallifrey with the Thirteenth Doctor, the Master revealed that he left the Matrix intact when he destroyed everything else. The Master used the Matrix to show the Doctor the truth about the Timeless Child, Tecteun and the Time Lords, but revealed that large portions of the Matrix's data relating to the life of the Timeless Child - in reality the forgotten past of the Doctor - and the Division had been erased even beyond the Master's ability to recover despite the fact that it had taken up a lot of space in the Matrix. The Master suggested that the images of Brendan, the disguised true story of the Timeless Child which he had transmitted into the Doctor's mind, were purposefully left behind by Tecteun as a gift or apology to her child, possibly as a way to decode and learn the truth about their past.

After revealing his new race of CyberMasters, the Master then trapped the Doctor inside the Matrix. Guided by a Matrix projection of a forgotten incarnation, the Doctor overloaded the Matrix with a blast of her memories, forcing it to release her.

In one of the infinite parallel universes of "possible space", (COMIC: Fire and Brimstone [+]Loading...["Fire and Brimstone (comic story)"]) the Matrix was located in the Panopticon.

In a parallel universe, the Valeyard won his battle with the Sixth Doctor within the Matrix, merging with him and gaining his remaining regenerations. When the Valeyard began altering history, Coordinator Vansell and the President took Mel inside the Matrix to observe, however became trapped there after the Valeyard destroyed Gallifrey with the Doomsday Weapon. Vansell gave Mel a time ring to escape so she could pursue the Valeyard. (AUDIO: He Jests at Scars... [+]Loading...["He Jests at Scars... (audio story)"])

Behind the scenes[[edit] | [edit source]]

  • In Steven Moffat's script for Hell Bent, when the Twelfth Doctor meets Me on the last fragment of Gallifrey at the end of the universe, she tells him that the Matrix has survived, though it is now "guttering", and that its ghosts sometimes tell her stories about "the little boy who didn't know how to give up". This dialogue was omitted from the broadcast version.[1]

The Presidents are categorised by in-universe chronological order. Loose chronological order applies for the lists, but when in doubt (as with the temporal uncertainty of the Time Wars), list them in the order in which they were first depicted as Presidents in the real world.
