The members were brought to Planet 1 by Sebastiene to hunt down the Tenth Doctor. The twelve members would be sent to sections of the planet which had been remade into their preferred hunting grounds. The Doctor would be randomly teleported into a section, and if the member there failed to kill him, Sebastiene would kill them. Over the course of the hunts, all the members except the Carpalian Witch were killed by Sebastiene or each other. (PROSE: The Doctor Trap)
