Profile
The Hydrax crossed from N-Space into E-Space where the crew found a unnamed primitive planet. There, turned into vampires by the Great Vampire, they controlled the natives for a thousand years until the arrival of the Doctor, who killed the Great Vampire and therefore the Three Who Rule. She aged, decayed and crumbled into dust. (DW: State of Decay)
