Avril Fenman

 was squire to Knight Cherry of the female Knights of Rowan, until one day she abandoned her knight whilst she took a crystal that gave her the power to transfer her mind into the bodies of others. She later used this power to take over Bernice Summerfield's body and sleeping with Adrian Wall, impregnating Benny with a Human-Killoran hybrid that would become Peter Summerfield (PROSE: The Squire's Crystal). Many years later, she came back to claim Peter as her son before getting killed by Irving Braxiatel. (AUDIO: The Curse of Fenman)
