Lost Soul

The Lost Soul is a level 7 rare mob ghost found roaming a small area by Agamand Mills in Tirisfal Glades. She is one of the many banshees of the Scourge that are still loyal to the Lich King and remains under his control. She is on a 1-2 hour respawn timer, however it is possible for several to be out at the same time. Her and Tormented Spirits' appearance may be connected.
