Bairn Muurn, the Crimson Numen is the spirit of both Lake Muurn and the Muurn River. During the Eternal Night eclipse, she appeared along the Aalen shoreline. Her presence startled the ferryman Nolan into his boat, where he was then swept out to a stormy, squid-infested sea; his rescue led to the discovery of Ka'doloki.
Muurn later appeared wandering the streets of Cyrene, complaining about blood raining from the sky. It was speculated that her concerns were the result of sacrificial offerings made by a local priest on top of the Lake Muurn lighthouse.
The monstrosity Khulhedra serves as Muurn's faithful guardian.
