Ngyr-Korath (The Ultimate Abomination and The Mad God of the Void) is a mythical being which existed before the planets, haunting the star-spaces. When life arrived it became mad and started to devour stars. A Cult to Ngyr-Khorath exists. Its legend appears in the Books of Thoth, The Chronicles of Thrang, the Uralte Schrecken, and The Texts of Mloeng. Von Konnenberg suggests that it is a form of the entity Mlandoth , and itself has an avatar, 'Ymnar.
Ngyr-Korath was created by Walter C. DeBill, Jr.
