Yog Thul, called the “Lurker on the edge of madness”, is a malign Chaos Entity of the Outer Darkness. His Nightmares unleashed are said to inflict Chaos Features. Yog Thul manifests in many planes, dimensions, and continuums as a force of chaos, madness, dissonance, evil, and violence. Not even Yog Thul can fully conceive of their own power or imagine into existence a single form for it to take; It manifests as a gruesome creature of any gender and/or race. Its Followers learn the discipline of speaking and recording their rites and deeds in Torquimat.
