The Lords of Cthul are enigmatic creatures of nightmare and madness, drawn from unknown nether regions to plague the world, aided by cultists who revere them like gods. Yasheth stands at a place of prominence in the blasphemous texts of the cults, an entity of negation and death, an invoker of antilife that transforms the world around it into whatever crawling horror the Cthul see as paradise. His shrieks alone have been known to rend the sanity from witnesses, and all living things quail and soon perish in his presence. —description from the game box
