From The Mythos Wiki
The Nosferetti exist in the shadow between the lands of the dead and the living. Unlike the Graven, they are ferociously intelligent. And unlike those animated shambling corpses, they have to feed on living blood to maintain their strength and sanity. Despite the apparent similarity, the Nosferetti have a consuming hatred for the anything Graven. Some say that the Nosferetti progenitor made a pact with a dark god, who is mortal enemies with the insane deity that enslaves the Graven. Others say that the Nosferetti abhor the living dead, because they represent what is most horrible to them… the loss of the mind, trapped in a corpse. Whatever the reason, a Nosferetti will stop at nothing in order to rend any living-dead thing into splinters of dry bone.
