- This page is about the lake. For other uses, please see Muurn (disambiguation).
Lake Muurn is a rocky lake that borders the southern edge of Cyrene, formed from a 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, kept by Mazzir, whose basement is inhabited by dumpy, bulbous scrags. For a time, visitors to the lake could make acquaintances with the ghostly Bairn Muurn, the Crimson Numen, but she has since returned to the depths of her watery domain.
