Belphegor - A demon of Sloth and Greed
Buzurivambavas is Bastard Demonspeak, and comes from the true Demonspeak bzhuu’vhambv’s, which means “carrying and crawling one”, or “one that carries and crawls”. They are a subtle kind of demon, and do not exhibit the terrible rage and bloodthirst of some other demons.
A group that wished to be 'ever-living' instead was cursed with 'never-dying'. Thier flesh rotted and fell fromthier bones but still they lived on. Now as skeletons they continue thier quest to remove thier curse. As skeletons they differ in that they do not need controlled or summoned. They are fully fledged NPCs with drives or ideas of thier own. Stabbing and slashing weapons would not affect them.
