History
In 2127, en route to Beta Two located in the Perugellis sector, the Hydrax was drawn into a CVE and through into E-space by the King Vampire. He placed it on a planet and went into hiding beneath it. The ship became a castle as it stood upright for 1000 years and rock built up around it, making it appear as if it were on a hill. The detached computer system was taken by the rebels. Kalmar managed to get it working and used its scanner function to watch the Hydrax and the surrounding area. The Doctor fired off one of the scout ships and used its eventual descent to impale the king with its steel frontage. The King's death resulted in the death of the former crew, whose life force was dependant on him. (DW: State of Decay)
