The single most Dangerous creature in all of the area outside the cave system, the Yin’Va’Seth is a one of a kind Creature that should not be where it is. It lacks it’s own Species, and seems to be some sort of eldritch abomination. It doesn’t seem to belong when it is, and if anything, is a creation of Azframentalar’s Ancestor, which used Flesh instead of plant matter and thorny vines.
