Melis, also called the Murk Witch, is a character in The Sorcerer's Daughter. She is a witch who served the sorcerer Arcannen, and she abducts and imprisons Chrysallin Leah on his orders. She lives in the Murk Sink, from which she takes her name.
Melis's physical appearance varies, though she most often appears to Chrysallin in the form of a young girl and also operates in the guise of an old woman. However, her true form is that of a hideous, oozing, tentacled creature.
