God Complex

The Prison Ship was made to hold and feed a captured Minotaur.

Features
The interior of the prison ship modified itself to take advantage of the fear of its subjects, creating rooms with their worst fears. The entrances would be blocked off and the interior would warp in on itself to get people lost. The ship could also transport people with great faith into itself. (DW: The God Complex)

History
An unknown civilisation captured a Minotaur which was masquerading as a god. They built the ship to contain it and set up the system to feed it faith. People would be shown their fears and then rely on their faith to fight it. The Minotaur would then replace the faith in whatever they believed with a faith in the Minotaur. The Minotaur would then feed on this faith, killing the subject.

Over time, the ship started to break down and developed a glitch. It was trapped in the shape of a 1980s Earth hotel and the rooms of the previous victims remained after their deaths. The Minotaur lost its will to live and wished to die, but the ship continued to feed it and it lacked the will to commit suicide.

One group of people was brought in and killed, with Lucy Hayward being the last survivor. The next group consisted of Joe Buchanan, Howie Spragg, Rita and Gibbis. The Eleventh Doctor, Amy Pond and Rory Williams were brought to the ship two day later. The Doctor, not knowing what they were facing, told them to fight their fears, which only made them more vulnerable. Joe was the first to be targeted and killed; while trying to avoid the Minotaur and save Joe, Howie, Rita and Gibbis were all possessed. When Howie was targeted, the Doctor tried to save him and contact the Minotaur, but Gibbis let Howie go to try to save himself and Howie was killed. Amy and the Doctor were both possessed soon after. When Rita realised she was next, she separated herself from the others and gave herself to the Minotaur. When Amy was targeted, the Doctor was finally able to figure what the Minotaur fed on. The Doctor was able to save her by showing that her faith in him was misplaced, thereby depriving the Minotaur of its food and allowing it to die. The ship shut down shortly after.
