Maurice Caven was the leader of a band of space pirates who robbed argonite shipments.
Maurice kidnapped Dom Issigri and blackmailed his daughter, Madeleine Issigri, into allowing him to set up a base on Ta. When his crimes were exposed, Caven threatened to blow up Ta, but was stopped by the Second Doctor. He, Dervish and all his men were killed when General Nikolai Hermack had Major Ian Warne destroy their Beta Dart. (TV: The Space Pirates)
