Islanne was the wife of Durlag Trollkiller. She and her two sons, Kiel and Fuernebol, were murdered by doppelgangers that had infiltrated Durlag's Tower. Greater Doppelgangers will take her form on Labyrinth Level 2 and her ghost is found lurking on Labyrinth Level 4. Her ghost will transport Gorion's Ward and party out of the tower after they kill the Demon Knight (in BG:EE, you can talk to her to get out at any moment).
