I'm looking for info about tradtional vampires, (i.e. non-Buffy/Dresden) as well as shamans.

What I have a grasp on so far is that vampires universally crave blood, have a pigment thing going on, and have some measure of immortality.

For shamans, I get that they are a medicine man type thing for Native American tribes, as well as a position of some authority in a village. I also base most of my stuff for them on the fact that in one way or another, they deal with the spirits of the dead.

What do y'all have for me?
