High priestess and leader of The Congregation of Necronominus, Morgolyth rules with a resigned coldness reflected in her faction’s deadly efficiency. Less savage than her brothers Malleus and Mandibulus, her ability to see through the eyes of her dead soldiers keeps her perpetually aware of her armies’ actions. Truly believing that the moment has arrived for her father Necronominus’ return, Morgolyth is readying her faction for a new era of evil.
