I acknowledge a range of fictional vampires, from the classic Dracula type to Jiang Shi to psychic vampires and the like.

Being parasitical is pretty central to my vampire-struct, regardless of type... not necessarily blood, but some kind of symbolic life force.

So is an aversion to sunlight.

So is needing to be invited in.

So is physical power, although that can take a lot of forms.

So is immortality.
