'''E-Space''', short for '''Exo-Space/Time continuum''' or simply '''Exo-Space''', ([[TV]]: {{cs|Full Circle (TV story)}}, [[PROSE]]: {{cs|Doctor Who and the State of Decay (novelisation)}}) was a "pocket-sized [[parallel universe]]," ([[PROSE]]: {{cs|Doctor Who and the Keeper of Traken (novelisation)}}) a separate negative universe ([[PROSE]]: {{cs|Castrovalva (novelisation)}}) existing alongside its positive, larger counterpart of [[N-Space]]. It possessed an unusual [[green]]ish tint. ([[TV]]: {{cs|Full Circle (TV story)}}, {{cs|State of Decay (TV story)}}) [[K9 Mark I]] called E-Space a "stellar [[enclave]]". ([[PROSE]]: {{cs|Jealous, Possessive (short story)}})


== Characteristics ==
As it was a [[sign|negative]] universe, locations in E-Space had negative co-ordinates, where N-Space co-ordinates were positive. When [[the Doctor's TARDIS]] materialised on the [[planet]] [[Alzarius]] after it had travelled into E-space, the [[TARDIS scanner]] continued to show images of [[Gallifrey]], which had the positive equivalent of Alzarius' spatial co-ordinates. The scanner was made functional again by replacing its original N-Space [[image translator]] with one native to E-Space. ([[TV]]: {{cs|Full Circle (TV story)}})
E-Space was not a [[parallel universe]] as that term is generally understood, having its own astronomy and unique inhabitants. {{What}} However it wasn't quite a perpendicular universe either, since it had [[humanoid]]s and other sentient life forms that were similar to ones of [[N-Space]]; thus it was more of an oblique universe or [[pocket universe]].{{Source}} However the fact that the Doctor's TARDIS was still able to draw the energy it needed to function from E-Space suggested that it shared some similarity to N-Space, as the ship was starved of energy upon entering a "true" alternate dimension ([[TV]]: ''[[Rise of the Cybermen]]''). [[The Doctor]]'s companion, [[Adric]], originated from E-Space ([[TV]]: ''[[Full Circle (TV story)|Full Circle]]'') and travelled with the [[Fourth Doctor]] back to N-Space ([[TV]]: ''[[The Keeper of Traken (TV story)|The Keeper of Traken]]''), where he ultimately died ([[TV]]: ''[[Earthshock (TV story)|Earthshock]]'') The Doctor's longtime companion, [[Romana II]], chose to stay in E-Space along with [[K9|K9 Mark II]] rather than return to N-Space with the Doctor and Adric. ([[TV]]: ''[[Warriors' Gate (TV story)|Warriors' Gate]]'')


E-Space was visually distinct from N-Space in that it possessed an unusual greenish tint. It was also considerably smaller than N-Space. ([[TV]]: ''[[Full Circle]]'', ''[[State of Decay]]'')
The planets [[Alzarius]], [[Terradon]], ([[TV]]: {{cs|Full Circle (TV story)}}) the [[vampire planet]], ([[TV]]: {{cs|State of Decay (TV story)}}) [[Ballustra]], ([[AUDIO]]: {{cs|The Invasion of E-Space (audio story)}}) [[Shapeer]], ([[TV]]: {{cs|Warriors' Gate (TV story)}}) [[Isenfel]], ([[AUDIO]]: {{cs|Equilibrium (audio story)}}) and [[Apollyon]] were all located within E-Space. ([[AUDIO]]: {{cs|The Entropy Plague (audio story)}})
 
Locations in E-Space apparently had negative co-ordinates, where N-Space was positive. When [[the Doctor's TARDIS]] materialised on the [[planet]] [[Alzarius]] after it had travelled into E-space, the [[TARDIS scanner]] continued to show images of [[Gallifrey]], which had the positive equivalent of Alzarius' spatial co-ordinates. Rather than being a simple optical relay, the system apparently depicted whatever existed at the ship's current co-ordinates. The Doctor suggested that the system operated off the absolute value of the co-ordinates and thus could not process negative co-ordinates. The scanner system was made functional again simply by replacing its original N-Space [[image translator]] with one native to E-Space. ([[TV]]: ''[[Full Circle]])''

E-Space, short for Exo-Space/Time continuum or simply Exo-Space, (TV: Full Circle [+]Loading...["Full Circle (TV story)"], PROSE: Doctor Who and the State of Decay [+]Loading...["Doctor Who and the State of Decay (novelisation)"]) was a "pocket-sized parallel universe," (PROSE: Doctor Who and the Keeper of Traken [+]Loading...["Doctor Who and the Keeper of Traken (novelisation)"]) a separate negative universe (PROSE: Castrovalva [+]Loading...["Castrovalva (novelisation)"]) existing alongside its positive, larger counterpart of N-Space. It possessed an unusual greenish tint. (TV: Full Circle [+]Loading...["Full Circle (TV story)"], State of Decay [+]Loading...["State of Decay (TV story)"]) K9 Mark I called E-Space a "stellar enclave". (PROSE: Jealous, Possessive [+]Loading...["Jealous, Possessive (short story)"])

As it was a negative universe, locations in E-Space had negative co-ordinates, where N-Space co-ordinates were positive. When the Doctor's TARDIS materialised on the planet Alzarius after it had travelled into E-space, the TARDIS scanner continued to show images of Gallifrey, which had the positive equivalent of Alzarius' spatial co-ordinates. The scanner was made functional again by replacing its original N-Space image translator with one native to E-Space. (TV: Full Circle [+]Loading...["Full Circle (TV story)"])

The planets Alzarius, Terradon, (TV: Full Circle [+]Loading...["Full Circle (TV story)"]) the vampire planet, (TV: State of Decay [+]Loading...["State of Decay (TV story)"]) Ballustra, (AUDIO: The Invasion of E-Space [+]Loading...["The Invasion of E-Space (audio story)"]) Shapeer, (TV: Warriors' Gate [+]Loading...["Warriors' Gate (TV story)"]) Isenfel, (AUDIO: Equilibrium [+]Loading...["Equilibrium (audio story)"]) and Apollyon were all located within E-Space.

Transit between the universes[[edit] | [edit source]]

The Fifth Doctor stated that the negative co-ordinates would make it very difficult for his TARDIS to travel there deliberately and not accidentally. (TV: Earthshock [+]Loading...["Earthshock (TV story)"])

By his seventh incarnation the Doctor was able to pilot his TARDIS between E-space and N-space, and was able to retrieve Romana II from the former. (PROSE: Blood Harvest [+]Loading...["Blood Harvest (novel)"]) K9 was also retrieved. (PROSE: Lungbarrow [+]Loading...["Lungbarrow (novel)"]) The amnesic Eighth Doctor made the trip with relative ease when visiting his fourth self, but on this occasion he was aided by the power of Rassilon, who was guiding the Doctor to visit his past seven selves and provide them each with aid.

CVEs[[edit] | [edit source]]

Travel between N-Space and E-Space could occur via a Charged Vacuum Emboitement, or "CVE". This was a hazardous and apparently random process, even using a TARDIS. (TV: Full Circle [+]Loading...["Full Circle (TV story)"])

The Logopolitans created the CVEs which linked together the two universes as part of their plan to forestall the overdue entropic collapse of their universe, N-Space, by opening up what had previously been a closed system and thus dissipating the accumulated entropy.

Following the disastrous consequences of the Tremas Master's visit to Logopolis, only one CVE remained open, in the constellation of Cassiopeia (from Earth's perspective). (TV: Logopolis [+]Loading...["Logopolis (TV story)"]) Unless further CVEs were later created, it was highly likely this was the route through which the Hydrax would later enter E-Space (TV: State of Decay [+]Loading...["State of Decay (TV story)"]) in the 22nd century. (PROSE: Lucifer Rising [+]Loading...["Lucifer Rising (novel)"])

The Gateway[[edit] | [edit source]]

On his return journey to N-Space the Fourth Doctor and his companions passed through a strange white void known to its most frequent inhabitants, the Tharils, as the Gateway. (TV: Warriors' Gate [+]Loading...["Warriors' Gate (TV story)"])

History[[edit] | [edit source]]

The King Vampire fled to E-Space at the end of the Eternal War and summoned the human ship Hydrax to provide servants. It turned the crew into Vampires and they ruled over the planet where the King subsequently hibernated, being known as the Three Who Rule. They awaited the Time of Arising when the King would finally reawaken. (TV: State of Decay [+]Loading...["State of Decay (TV story)"])

The Fourth Doctor, Romana II and K9 Mark II accidentally entered E-Space through a CVE. They landed on Alzarius where they met Adric, an inhabitant of the universe who secreted himself aboard the Doctor's TARDIS to join the Time Lord on his travels. (TV: Full Circle [+]Loading...["Full Circle (TV story)"]) They arrived on the vampire planet where they helped local rebels overthrow the Three Who Rule and used the Hydrax to fatally impale the King as he awakened. (TV: State of Decay [+]Loading...["State of Decay (TV story)"]) They spent months trying to find another CVE. During this time, they encountered the Farrian, who had entered E-Space through a CVE. They had opened it themselves using Block Transfer Computation, a skill they learnt from a prisoner. The Farrian attempted to conquer the planet Ballustra, but the Doctor destroyed the device that generated the CVE, forcing them to retreat. (AUDIO: The Invasion of E-Space [+]Loading...["The Invasion of E-Space (audio story)"])

The Doctor and Adric left E-Space through the Gateway. Romana and K9 chose to stay behind, Romana wanting to avoid a return to Gallifrey and K9 accompanying her after damage to his circuits prevented him making the crossing back to N-Space. (TV: Warriors' Gate [+]Loading...["Warriors' Gate (TV story)"])

Some years later, the Fifth Doctor, Nyssa, Tegan Jovanka and Turlough accidentally travelled back into E-Space when the TARDIS passed close to another CVE, activating a program Adric had unintentionally programmed into the TARDIS. (AUDIO: Mistfall [+]Loading...["Mistfall (audio story)"]) After landing on Alzarius and travelling to Isenfel, (AUDIO: Equilibrium [+]Loading...["Equilibrium (audio story)"]) the Doctor realised that E-Space was on the verge of collapse due to the entropy build-up caused by the last CVE, which was being opened at irregular intervals to allow the residents of E-Space to escape back to N-Space.
