Stevenage was the home galaxy of Geoff Vampire, and quite possibly of the whole Vampire race.. He intended to transport himself and his unwilling pawns there as part of his schemes, but this was foiled by Svetlana who shut down Geoff's computer during its countdown, finishing any chance Geoff had of getting to Stevenage.

Quite when Geoff came from Stevenage to Earth is unknown, but considering he is said to have known Van Helsinki for some time, the original journey must have happened some time ago.
