Deep in the Osirian desert stands the blank-faced monument referred to as the Sightless Sphinx. In search of the taken mummy of Chisisek, the architect of the flying tomb from the Sky Pharaoh Hakotep I, Ezren, Harsk, Merisiel and Valeros track the cult from the Overlooked Pharaoh to its key headquarters in the sphinx.

There they face monstrous mercenaries and servants from the demon lord Areshkagal before finally confronting the masked cultists and their leader, the Forgotten Pharaoh.
