In the Dawnguard DLC, in the room to the left of the grand hall of Volkihar Keep, there is a display case containing a hagraven's claw, a sabre cat's eye, a daedra's heart, a dog's ribcage, and a gold ring. This is a nod to Castlevania II, in which Simon Belmont must collect and destroy the nail, eyeball, heart, ring, and ribcage of Dracula to defeat him.
