101-form

The Great Houses' attempt to create a 101-form timeship shortly before the War was a confidential and experimental project, believed to have ended in failure. Its rebellious result was the only known humanoid timeship not to be a descendant of Compassion.

It was the first attempt to create a partially-organic timeship, with a mind that could relate directly with the pilots rather than a more abstract intelligence; (PROSE: Crimes Against History, The Book of the War) the earlier attempt to create Model 51 TARDISes with personalities that the Gallifreyan pilots could relate to using a purely digital "personality matrices" had been a failure, with the ships' personalities being unstable for reasons the Gallifreyan cyberneticists never understood. (GAME: The result of the experimental upgrading of a timeship was viewed as another failure, producing "such a monstrosity that it barely qualified as a timeship at all", being "utterly beyond the control of its creator". Although normal protocol would have been for the failed experiment to be destroyed, the ship's fate was unrecorded, (PROSE: Crimes Against History, The Book of the War) leading to incorrect speculation that Antipathy was the escaped 101-form. (PROSE: Of the City of the Saved...)

In fact, a timeship modified to be able to take humanoid form, who was described as "family" by Compassion, (AUDIO: Sabbath Dei, In the Year of the Cat) who was the one and only member of the 102-form generation and widely considered the first true humanoid TARDIS, (PROSE: The Shadows of Avalon) resurfacing under the alias of "Lolita". Lolita had vampiric traits and brought her own agenda to the War, manipulating the Great Houses and intending to overthrow them to institute a "new kind of history". (PROSE: The Book of the War, AUDIO: The Eleven Day Empire, etc.)

Behind the scenes
Although this bit of wordplay has never been explicitly pointed out, Lolita's alias is a reference to her serial number as a timeship ("101ita").
