Morgan's Mother
Queen of Castle Pendragon
Uther - husband
Morgan - daughter
Unknown Pendragon - grandchild

Morgan's Mother was the first wife of Uther Pendragon, mother of Morgan Pendragon, and former Queen of Castle Pendragon. Uther killed her in order to marry Igraine after having fathered a son with her against her will. This caused the enmity between Uther and Morgan, Morgan and Igraine, who played along in the end and between Arthur and Morgan because of Arthur having legitimised this. It also caused enmity between Morgan and Merlin, who willingly also played along with it for his own reasons.
