Ygraine Pendragon

Ygraine Pendragon (née de Bois) was the queen of Camelot through her marriage to the king, Uther Pendragon. She and Uther were friends with the sorceress Nimueh. Igraine was unable to bare children. Because he wanted a son, Uther asked Nimueh to use magic to allow Igraine to give him a son. Nimueh agreed, and the result was Arthur Pendragon. However, unknown to Nimueh at the time, the law of magic states that to create a life another must be destroyed. The result of this was Igraine died in childbirth. Uther blamed Nimueh and all magic for her death and set about attacking all kinds magic there afterwards, resulting in The Great Purge. (Excalibur). She will appear in Series 2, in the episode "The Sins of the Father".
