Sophia (Professor Bernice Summerfield and the Glass Prison)

Sophia was Bernice Summerfield's friend and companion during her imprisonment in the Fifth Axis Glass Prison. She was an expert in etymology and helped Benny decide on her child's name. She worked out that the doctor treating Benny wasn't a doctor but was the Fifth Axis Imperator and killed him before he could kill the child. She became Peter's godmother before eventually returning to Grellor. (PROSE: The Glass Prison)

She met Bernice and Peter again several years later, discovering at the time of her visit that a group of Grel from the future intended to travel back in time and kidnap Peter. She helped Bernice, Jason Kane and Peter escape. During this escapade she saw the eventual death of her own son at Peter's hands. (AUDIO: The Grel Escape)
