Jaden Muirden was the wife of Gregor and the mother of Edwin Muirden. She and her husband were sorcerers that followed the ways of the Old Religion and were teaching their son the use of magic. They were friends with Gaius. When the Queen died in childbirth, King Uther began to prosecute all forms of magic and executed everyone that he caught practicing magic. Jaden and her husband suffered this fate, as they were sentenced to be burned at the stake. When they were being burned, Edwin tried to save his parents but only being disfigured by the fire. Many years later Edwin returned to Camelot to avenge his parents death by killing Uther, but he was killed by Merlin. According to Gaius, Jaden and Gregor started to practise dark magic (A Remedy to Cure All Ills).
