Sarcyn's mother worked in a brothel in Cerrmor. She was murdered by a patron when Sarcyn was 7. He had a younger sister named Evy who died in Cannobaen. Their fathers are unknown.
Sarcyn and his sister were kicked out of the brothel after their mother was murdered. They lived on the street until Alastyr found them and took them to live with him. Alastyr raped them until they each reached puberty. Evy was sold to a brothel in Myleton and Sarcyn was taken on as his apprentice in dark dweomer.
