the main issue is that these beings - almost all of the huge taxonomy are dead/undead and are disconnected from the source and run on vril/prana type batteries and storage in artefacts. they are lifeforce hungry.
therefore they all probably sit amongst the overall classification of vampire. various types of direct and indirect vampirism .. by proxy, by artefact, by spiritual psychology, by direct eating, indirect empathic vamprisim, life force miners, intelligent and semi-intelligent outrage creators and lifejuice drinkers telepathic vampires, lotus/chakra eaters/soul eaters.
