Terrin Blakely

 was the husband of Alyst Blakely and the father of Sabel, Ollus and Jenibeth Blakely. He and his wife committed suicide to keep their knowledge on the Cradle of the Gods save from the Daleks, following warnings from their friend Hogoosta not to give the information to anyone else. They were later recreated by the Cradle and Jenibeth's mind. (PROSE: The Dalek Generation)
