Igraine was an evil Adoni sorceress who had at least three children important to the Lords of Avalon Series. Her sister is Narishka.
Igraine drugged and seduced Falcyn in order to conceive Maddor.
She probably killed her first two husbands. Then she seduced Uther, who became her third husband. From that union was born Arthur.
It is not known who is the father of her daughter Morgen Le Fey.
