THE STORY
The TARDIS arrives on a planet where a savage tribeknown as the Sevateem worship a god called Xoanon. The Doctor discovers that Xoanon is in fact a spaceship computer that he tried to repair at some point in the past and inadvertantly drove mad by giving it a multiple personality. The computer is tended to by another group of humanoids, the Tesh. These are the descendants of the ship's original technicians, while the Sevateem are the descendants of the original survey team. The Doctor, with the help of a Sevateem girl called Leela , manages to gain access to the ship and wipe the additional personalities from the computer, leaving it sane and in control of its functions once more. Leela, pushes her way into the TARDIS and the Doctor gains a new companion.
