The Machine

The Machine, a creation of Omega, was a prototype TARDIS. The Other used it to get Patience off ancient Gallifrey.

The Machine was primarily a column, nearly a mile tall, with ten metre-thick cables spilling out of it. While mostly grey, some of its panels had been removed to reveal yellow and orange light sources. The cables and power couplings had grown out of the Machine in an organic fashion over the millions of years it had lain buried under the ice of a remote planet. At its base was a door to a small antechamber that functioned as a control room. The Machine was dimensionally immanent: it was smaller on the inside than the outside.

The primitive nature of the Machine caused violent ruptures in the Time Vortex where it had travelled, which drew in and immobilised the Fifth and Seventh Doctor's TARDISes. The Fifth Doctor and Patience attempted to heal this damage by remotely piloting the Machine back to Gallifrey to re-stitch the ruptures its original journey had created, but this nearly resulted in the destruction of Gallifrey when Provost-General Medford loading the Machine with twenty-one fusion bombs capable of destroying all of Kasterborous in the distant past. The Fifth and Seventh Doctors were able to halt the Machine long enough for the Seventh to trick the Ferutu into holding it in place, resulting in the Machine's past self colliding with it as it left Gallifrey, the collision destroying the future Machine and the bombs in the Time Vortex while the past Machine crash-landed in the past to fulfil its intended role in history.

Behind the scenes

The description of the interior of the Machine resembles the interior of TARDIS from the film Dr. Who and the Daleks.
