Lanu Du, Kalsu for "No Face" or "Faceless", is the name given to the mysterious, Chaos-associated deity worshiped by the Nazedha Empire, its Sages, and the Cult of Lanu Du. In standard practice, the God is worshiped on an equal footing with Chakrasul, and held to be the exemplar of Chaos and Destruction. According to the traditions of the Sages, it is Lanu Du that will bring about the end of the world once the Light is snuffed out and an ocean of blood is spilled, a goal which the Cult and the Sages have worked toward since their founding by Lahkencai.
It is at this time unclear, compared to many other deities, whether Lanu Du actually exists or if Lahkencai simply invented him.
Lanu Du's shrines take the form of bloodstained monoliths, and are far more common on the islands; a few, however, have been erected on the western coast of Sapience, particularly in Dun and in Huanazedha.
