Morgan le Fay , alternatively known as Morgan le Faye, Morgen, Morgaine, Morgain, Morgana, Morganna, Morgant, Morgane, Morgne, Morge, Morgue, and other names, is a powerful enchantress in the Arthurian legend. Early works featuring Morgan do not elaborate her character beyond her role as a fay or sorceress. She became both more prominent and morally ambivalent in later texts, in particular in cyclical prose works such as the Lancelot-Grail and the Post-Vulgate Cycle, in which she turns into a dangerous arch-enemy of King Arthur and an antagonist of some tales.
