Hydrax

The Hydrax was a Human crewed ship from the 22nd century.

Technology
The Hydrax was equipped with a complex computer system with features such as scanners that could present views of a target, they were capable of seeing through surfaces like an x-ray. The ship had three scout ships each with a steel bolt on top. (DW: State of Decay, NA: Lucifer Rising)

Crew

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 Hydrax 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)

Behind the scenes

 * The Hydrax designs were drawn up by Christine Ruscoe. The original concept showed a greater link between the various sections. Filming for the Hydrax's interior took place at Mont Saint Michel.
