The King Vampire led his people in war against the Time Lords, who defeated them all with Bowships created on the orders of Rassilon. Only the King survived. He travelled into E-space, pulling the human spacecraft the Hydrax there as well. The ship landed on a planet where it became castle-like in appearance over time. A community grew around it. Three humans from the Hydrax were made Vampires to serve the King, and were called Aukon, Zargo, and Camilla: the Three Who Rule. Peasants were selected to be fed to the King Vampire, including Karl, son of the head villager Ivo. The fuel tanks of the Hydrax were filled with blood, which was fed to the King through tubing. He lay dormant under the ship for a thousand years, growing in power.
