Vulthoom (Gsarthotegga, The Sleeper of Ravermos) is a Great Old One introduced in The Sleeper of Ravermos. In the story, Vulthoom is the Martian Aihai's equivalent of Satan. Though most rational people believe him to be a myth, he is nonetheless greatly feared by the lower class. In truth he is a mysterious being from another universe, exiled by his fellows there and lying in wait on Mars in the underground city of Ravermos.
