'''Hypercubes''' were essentially letters sent between [[Time Lord]]s, but they were white cubes that bore a Time Lord's thoughts or speech. They were then sent through [[time]] and [[space]] to Gallifrey or to someone they trusted enough to rescue them. They could be used by [[human]]s as well as Time Lords. ([[PROSE]]: ''[[Vampire Science]]'', ''[[The Ancestor Cell]]'') They were theoretically impossible to intercept, but a [[Little Brother (Unnatural History)|Little Brother]] of [[Faction Paradox]] intercepted a cube the [[Eighth Doctor]] sent to the Time Lords. They were mainly owned by members of official [[:Category:Gallifreyan organisations|Gallifreyan organisations]]. ([[PROSE]]: ''[[Unnatural History]]'')
'''Hypercubes''', ([[PROSE]]: {{cs|Vampire Science (novel)}}, {{cs|The Book of the War (novel)}}) also known as '''tesseracts''', ([[PROSE]]: ''[[The Ancestor Cell (novel)|The Ancestor Cell]]'') '''T-mail''' ([[PROSE]]: {{cs|Shakedown (novelisation)}}) '''Time Lord message pods''' ([[PROSE]]: {{cs|Unnatural History (novel)}}) or '''Psychic Containers''', ([[GAME]]: {{cs|The Gunpowder Plot (video game)}}') were a [[Gallifrey]]an form of communication, physically resembling white cubes. They were able to store a [[Time Lord]]'s thoughts or speech and could be sent through [[time]] and [[space]], ([[TV]]: {{cs|The War Games (TV story)}}, {{cs|The Doctor's Wife (TV story)}}) travelling through the [[space-time continuum]] itself.

The [[Second Doctor]] sent a cube message to the [[Time Lord]]s by laying down the six flat, featureless faces of the cube in front of him, and using his psychic powers to fill this "very special sort of box" with "all the information about what [had] been going on here, and an appeal for help", with the box seeming to assemble itself of its own accord.

[[Irving Braxiatel]] once used a hypercube to contact his people. ([[PROSE]]: ''[[Tears of the Oracle]]'')
[[Irving Braxiatel]] once used a hypercube to contact his people about the developments he had learned about [[the People]]. ([[PROSE]]: ''[[Tears of the Oracle (novel)|Tears of the Oracle]]'') The [[First Doctor]] once accidentally returned [[Ian Chesterton]] and [[Barbara Wright]] to [[Shoreditch]] [[1963]], but ''before'' had left. When the Doctor refused to let them stay, Ian and Barbara argued with the Doctor about him having kidnapped them. Not long after, [[Susan Foreman]] showed a similar anger at the Doctor having taken her away from [[Gallifrey]] without her consent. The Doctor decided that using the Hypercube was the only way to fix all of their problems. Learning about this plan, the three companions rushed back to [[The Doctor's TARDIS|the TARDIS]], where Susan disuaded him, scared of the consequences. ([[AUDIO]]: ''[[Home Again, Home Again (audio story)|Home Again, Home Again]]'')
 
[[Stoyn]]'s beacon on the sentient planet he was situated on used six white squares, the components of a hypercube. After his beacon was disabled, the [[Second Doctor]] pocketed the squares. ([[AUDIO]]: ''[[The Dying Light (audio story)|The Dying Light]]'')
 
He was later forced to use them to ask the Time Lords to return the soldiers kidnapped by the [[War Lord]]s to their own time periods, as he could not do so on his own. The Doctor constructed his hypercube from the six white squares by merging them with his mind, assembling them into the shape of a cube. Calling upon his people for help proved to be a personal sacrifice for the Doctor, effectively turning himself in, resulting in his separation from his companions [[Jamie McCrimmon]] and [[Zoe Heriot]], his [[exile on Earth]], and a forced [[regeneration]] into his [[Third Doctor|third incarnation]]. ([[TV]]: ''[[The War Games (TV story)|The War Games]]'')
 
The [[Fifth Doctor]] used a hypercube to notify the Time Lords that he had found [[Zero (Spring)|Zero]]. ([[AUDIO]]: ''[[Spring (audio story)|Spring]]'')
 
The [[Sixth Doctor]] was prepared to use a hypercube to summon the Time Lords for help in preventing the [[Cybermen]] from changing history, even though he was aware he would be punished with no way of defending himself. ([[AUDIO]]: ''[[Last of the Cybermen (audio story)|Last of the Cybermen]]'')
 
The [[Seventh Doctor]] later slipped [[Ace]] a tesseract on the planet [[Heaven (Love and War)|Heaven]] in order to be able to contact her in the future. ([[PROSE]]: ''[[Love and War (novel)|Love and War]]'') He later used it to do so whilst arranged for the TARDIS to purge the infection it had contracted after their visit to [[Tír na n-Óg]]. ([[PROSE]]: ''[[Deceit (novel)|Deceit]]'') He also had [[Roz Forrester]] send him a T-mail message to report on her progress tracking the [[Rutan]] [[Karne]]. ([[PROSE]]: {{cs|Shakedown (novelisation)}})
 
During the [[War in Heaven]], [[the War King]] kept the twelve components of a hybercube stacked neatly on his desk as the last remaining link to his past as a [[renegade Time Lord|renegade]]. ([[PROSE]]: ''[[The Book of the War (novel)|The Book of the War]]'')


The [[First Doctor]] collected his when he worked for the [[Bureau of Possible Events]], but left it behind on [[Gallifrey]] when he escaped with [[Susan Foreman|Susan]]. It was returned to him by his mentor [[K'anpo Rimpoche]] shortly before his first regeneration, along with his [[Five Hundred Year Diary]]. ([[PROSE]]: ''[[The Three Paths]]'')
[[File:Ghosts of Christmas Past short story.jpg|thumb|right|The [[Eighth Doctor]] receives [[Susan Foreman]]'s hypercube. ([[PROSE]]: ''[[Ghost of Christmas Past (short story)|Ghost of Christmas Past]]'')]]
During the [[Last Great Time War]], the [[Eighth Doctor]] received a hypercube from [[Susan Foreman]]. ([[PROSE]]: ''[[Ghost of Christmas Past (short story)|Ghost of Christmas Past]]'') Susan herself was sent several urgent hypercubes from Gallifrey during the Time War. Most of them were removed by the Eighth Doctor, who didn't want her to join the war.

([[AUDIO]]: ''[[One Life (audio story)|One Life]]'')


The [[Second Doctor]] used a hypercube to ask the Time Lords to return the soldiers kidnapped by the [[War Lord]]s to their own time periods, as he could not do so on his own. Unlike the Hypercube he would find in [[The Doctor's Wife|the future]], the Doctor constructed this one from six separate white cards and merged them with his mind. Calling upon his people for help proved to be a poor choice for the Doctor; it led to his [[Exile on Earth]] as the [[Third Doctor]] and the separation from his companions [[Jamie McCrimmon]] and [[Zoe Heriot]]. ([[TV]]: ''[[The War Games]]'')
Following the Last Great Time War, a hypercube was on sale at the [[Fluren Temporal Bazaar]]. ([[COMIC]]: ''[[Weapons of Past Destruction (comic story)|Weapons of Past Destruction]]'')


Hundreds of Time Lords, stranded in the [[bubble universe]] by [[House]], used hypercubes to send distress calls. However, none of them remained alive by the time other Time Lords arrived; House killed them for parts to repair [[Auntie (The Doctor's Wife)|Auntie]] and [[Uncle (The Doctor's Wife)|Uncle]]. This produced [[TARDIS]]es to feed House for five thousand years. The last Time Lord to arrive on [[House]] was the Doctor's good friend [[the Corsair]]. He recorded his hypercube, but was killed before he could send it. The Corsair's hypercube was sent into [[normal Space|the main universe]] and found [[the Doctor's TARDIS]] because there were no other Time Lords left in time and space. After [[Eleventh Doctor|the Doctor]] arrived in the bubble universe, he heard the [[distress call]]s on [[Nephew]]'s [[translation sphere]] and thought this meant there were other living Time Lords besides Corsair. All the Doctor found was a cabinet filled with hypercubes House had stolen from the dead Time Lords. ([[TV]]: ''[[The Doctor's Wife]]'')

History of usages[[edit] | [edit source]]

Irving Braxiatel once used a hypercube to contact his people about the developments he had learned about the People. (PROSE: Tears of the Oracle) The First Doctor once accidentally returned Ian Chesterton and Barbara Wright to Shoreditch 1963, but before had left. When the Doctor refused to let them stay, Ian and Barbara argued with the Doctor about him having kidnapped them. Not long after, Susan Foreman showed a similar anger at the Doctor having taken her away from Gallifrey without her consent. The Doctor decided that using the Hypercube was the only way to fix all of their problems.

Stoyn's beacon on the sentient planet he was situated on used six white squares, the components of a hypercube. After his beacon was disabled, the Second Doctor pocketed the squares. (AUDIO: The Dying Light)

He was later forced to use them to ask the Time Lords to return the soldiers kidnapped by the War Lords to their own time periods, as he could not do so on his own. The Doctor constructed his hypercube from the six white squares by merging them with his mind, assembling them into the shape of a cube. Calling upon his people for help proved to be a personal sacrifice for the Doctor, effectively turning himself in, resulting in his separation from his companions Jamie McCrimmon and Zoe Heriot, his exile on Earth, and a forced regeneration into his third incarnation. (TV: The War Games)

The Fifth Doctor used a hypercube to notify the Time Lords that he had found Zero. (AUDIO: Spring)

The Sixth Doctor was prepared to use a hypercube to summon the Time Lords for help in preventing the Cybermen from changing history, even though he was aware he would be punished with no way of defending himself. (AUDIO: Last of the Cybermen)

The Seventh Doctor later slipped Ace a tesseract on the planet Heaven in order to be able to contact her in the future. (PROSE: Love and War) He later used it to do so whilst arranged for the TARDIS to purge the infection it had contracted after their visit to Tír na n-Óg. (PROSE: Deceit) He also had Roz Forrester send him a T-mail message to report on her progress tracking the Rutan Karne. (PROSE: Shakedown [+]Loading...["Shakedown (novelisation)"])

During the War in Heaven, the War King kept the twelve components of a hybercube stacked neatly on his desk as the last remaining link to his past as a renegade. (PROSE: The Book of the War)

The Eighth Doctor receives Susan Foreman's hypercube. (PROSE: Ghost of Christmas Past)

During the Last Great Time War, the Eighth Doctor received a hypercube from Susan Foreman. (PROSE: Ghost of Christmas Past) Susan herself was sent several urgent hypercubes from Gallifrey during the Time War. Most of them were removed by the Eighth Doctor, who didn't want her to join the war. (AUDIO: All Hands on Deck) Cardinal Ollistra sent the Time Lord command to collect her when the Doctor's TARDIS crashed. (AUDIO: One Life)

Following the Last Great Time War, a hypercube was on sale at the Fluren Temporal Bazaar. (COMIC: Weapons of Past Destruction)

Hundreds of Time Lords who were stranded in a bubble universe by House attempted to use hypercubes to send distress calls. However, House killed many or all of them for parts to repair Auntie and Uncle, feeding itself on their TARDISes for five thousand years. One Time Lord to arrive on House was the Doctor's good friend the Corsair. He recorded a hypercube, which was sent into the main universe. It eventually found the Doctor's TARDIS, because there were no other Time Lords left in time and space. After the Eleventh Doctor arrived in the bubble universe, he heard the distress calls on Nephew's translation sphere and thought this meant there were other living Time Lords besides Corsair. The Doctor was enraged when he found a cabinet filled with hypercubes which House had stolen from the dead Time Lords. (TV: The Doctor's Wife)

The Doctor kept a hypercube in the TARDIS Drawing Room. (GAME: The Gunpowder Plot)

The New Dalek Paradigm and the Dalek Time Controller sent a hypercube to the Eleventh Doctor's TARDIS to lead him to the planet Gethria. From there, the Daleks manipulated the Doctor into leading them to the Cradle of the Gods, a monument which they planned to use to transform the Sunlight Worlds into copies of Skaro. Aided by Ollus, Sabel and Jenibeth Blakely, the Doctor set the Cradle to self-destruct and the Daleks abandoned the plan. (PROSE: The Dalek Generation)

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

In real-world mathematics, a hypercube is a higher-dimensional analogue of a cube. The hypercube of four dimensions is specifically called a "tesseract".

Some of the voice lines used for the Hypercubes in The Doctor's Wife were included individually in the game files of The Gunpowder Plot - assumedly for application on the Hypercube that can be found in The Drawing Room - but ultimately they went unused. The full lines can be heard here, and include explicit references to Fluid Links, the War Lord home planet, and Minyos: https://youtu.be/gItK0Yz4USs
