Floor 500

Floor 500 was the top floor of Satellite Five where people believed the walls were made of gold. The environmental systems of Satellite Five had been configured to vent all heat away from Floor 500, keeping it cold enough for the Jagrafess to survive, attached to the ceiling of the main control room. Ultimately captured by the Editor and about to be killed by the Jagrafess, the Doctor and Rose Tyler were saved by Cathica Santini Khadeni, a human journalist who reversed the environmental systems. The Jagrafess overheated, swelled up and exploded. The Jagrafess's Human associate, the Editor killed journalists and reanimated their corpses via their chip implants to work for him.
