Lake Muurn is a rocky lake that borders the southern edge of Cyrene and forms the border of the valley in the Vashar Mountains. It is connected to the Muurn River Valley by way of a series of violently surging caverns inhabited by the monstrosity Khulhedra. At the southern end of the lake sits an island with a lighthouse, the basement of which is inhabited by dumpy, bulbous scrags. Although now returned to its watery grave, visitors to the area recently met the acquaintance of the ghostly Bairn Muurn, the Crimson Numen.
