Morgawse, Morgause...whatever you like. She is referred to by this name in the poem of the same name by A.E. Housman. She is the Witch-Queen of Orkeney who in is the daughter of Gorlois and Igraine (King Arthur's mother), Uther Pendragon takes Igraine as his wife making her Arthur's half sister. In some versions she is also Morgana Le Fey's sister too. And she is mother to Gawain, Agravaine, Garheris, Gareth and Mordred (who slays Arthur, and is his son...)
Highly convenient name considering Merlin's involvement in the Dresden Files.
So is Mab then Margause? A witch in a line of witches descended from Medea and Hecate? How do both Athame's fit in?
Mab did say she was once mortal...
