Gethria

 was a desert planet located near the Sunlight Worlds. The Cradle of the Gods was found on the planet by the Klektid Hogoosta and his excavation team.

On a mission from Gethria to Carthedia, the charter ship KS55NZ/4 was attacked by Daleks, and among the dead was Ollus Blakely. Back on Gethria, the Daleks faked a funeral for Ollus in order to lure the Eleventh Doctor into a trap. (PROSE: The Dalek Generation)
