In Arthurian legend, the figure depicted as a sorceress and advisor to King Arthur is Morgana Le Fay (or Morgaine). Often illustrated as a complex character, Morgana embodies both benevolence and malevolence, serving as a healer and a manipulator. Her profound understanding of magic highlights the duality of her character, as she plays crucial roles in Arthur’s destiny and the unfolding of Camelot's fate, reflecting themes of power and betrayal in Arthurian tales.
