Gaveston
From Tardis Wiki, the free Doctor Who reference
Gaveston was an asteroid which neighboured the planet DV Acrol 8. It was home to Cyrian, who was stranded on DV Acrol 8 after his spaceship crashed. Pursued by Cybermen, he was rescued by the Rani who took him aboard her TARDIS to become her travelling companion, though in effect he became a servant. (NOTVALID: Rescue)
