Ruthven's TARDIS

Lord Ruthven used a TARDIS during the War in Heaven. (PROSE: Alien Bodies) The structure of the ship was modelled after the helix of Ruthven's DNA. (AUDIO: The Eleven Day Empire) It had detection shielding. (AUDIO: The Shadow Play)

Ruthven piloted his timeship into the Eleven-Day Empire while he was working with Lolita and the Seventy-Ninth Sontaran Assault Corps. During negotiations with Faction Paradox, he pointed it out to Eliza. (AUDIO: The Eleven Day Empire) Once negotiations finished, Ruthven returned to his timeship and met with Lolita. When the two left the ship to further their plans in the Empire, they ordered several Sontarans - including Kine - to guard it while they were gone. Justine, Eliza, and Morlock took out the Sontarans using their shadow-weapons and boarded the ship. Morlock ordered Justine and Eliza to use the ship to escape to the "old homeworld". Justine was able to pilot it, but she didn't immediately leave the Empire; she first took the ship to the lair of the Unkindnesses and then kept the ship within the Empire, observing Lolita's takeover through view-screens, until Lolita began consuming the Empire, forcing Justine and Eliza to use the ship to flee. (AUDIO: The Shadow Play)

Justine and Eliza landed the ship off the coast of Portsmouth in 1762, where they were seen by the locals and attacked. Justine hid the ship in a safer location while she and Eliza stayed in 1762: the cave beneath Medmenham Abbey where Mary Culver had performed her ritual shortly beforehand. When fighting broke out during the Hellfire Club's ball in the Abbey, Justine channeled the exterior of the timeship into giant tentacles which burst from the ground and attacked people. (AUDIO: Sabbath Dei)

Homunculette heard a story that an anarchitect had hijacked the TARDIS and transformed its central corridor into an infinite möbius loop. (PROSE: Alien Bodies)
