Vampire's Masquerade Temptation

Eats Blood and Nothing else. When exposed to sunlight, , a thick umbrella, and long sleeves do the trick. They're old enough to have had several identity changes. They live in a crumbling old castle on a cliff over a dark and treacherous sea. They command a talking skull that offers snarky but wise advice. They have a love/hate relationship with a demon with whom the vampire broke a deal with. They learned a number of abilities throughout their long life, including controling lesser vampires and telekinesis. They can spit intensely potent venom that causes necrotic rot.
