Morgan le Fay

Morgan le Fay, from the saga of King Arthur, is the witch with the long dark hair and beauty mark on her face.

History
Morgan was part of Ozma's super team put together to defeat Mister Dark, where she was given the "superhero name" The Green Witch.

After Snow White is taken captive by Prince Brandish, Morgan is seen discussing rescue plans with her fellow witches, Ozma and Maddy. Because Brandish has bewitched himself so that any injury inflicted on him will also hurt Snow, the task is easier said than done, especially since the spell is difficult to break. Morgan comes up with a plan. They will not try to break the spell, but add to it instead: She will build in a delay between cause and effect, which will give them some wiggle room between the moment Brandish is killed, and when the same thing happens to Snow. Morgan begins the hard work of casting the spell, while Rose Red rescues Snow while Brandish is distracted. Snow then engages Brandish in a sword fight, while Morgan slowly, but carefully manages to unwind the spell that Brandish has cast on himself, allowing Snow stab him straight through his heart.

Unfortunately, the spell is not broken, merely delayed. In the Camelot story arc, Morgan breaks the bad news to Snow: sooner or later, the fatal wound is bound to be inflicted on Snow herself, which will kill her.

Fairest In All the Land
Morgan, along with Bean Nighe, a Fabled oracle, were victims at the hands of Goldilocks. While Cinderella is able to bring back the victims of Goldilocks; she's only allowed to choose half. She ultimately chooses Morgan Le Fay, seeing her more valuable an ally for Fabletown. Snow White's fate is resolved in the same story; she is stabbed through the heart (as Morgan predicted) by Goldilocks. Fortunately, Cinderella is able to bring her back to life.

Later Morgan was seen having joined Rose Red's "New Camelot" as her new court magician,a post Morgan had taken seriously and has become Immensely loyal to Rose Red as the new "King" of her "New Round Table", as seen where she even hesitated to share any information on Rose's activities during her meeting with the other 13th Floor members and later upon Rose's deceleration of war against Snow White, Morgan was seen having stayed by her side as one of her primary lieutenants of her army.
