Scapegrace

Scapegrace was a space station. Cornelius Morningstar experimented with time travel on the station, hiring Stralla Cushing. She set off a bomb to kill Dron and Gorl, damaging the station and knocking it off of its axis. It was almost destroyed by the nearby hyperspace gate but was saved by the Eighth Doctor.
