Lake Mulsantir is a turbulent body of water that forms part of the border with Thay. In years past, the Red Wizards stocked the lake with hostile magical crossbreeds, but such things were as likely to return south against their creators as to go north, so this practice has ceased. Some of the more cunning creatures survive, though, and are blamed whenever boats disappear on this lake. Mulsantir connects with Lake Ashane through a broad passage referred to as the River Mulsantir.
