Tell us more about the vampires, since you haven't really talked about it much here.

I'm not well researched in it, but it seems to me they feed on energy (loosh) more than blood.

Are they generally well known and recognizable, or do they prefer to remain hidden?

I think if I were a vampire / parasite I would want to give myself a platform on which to be worshiped, like a politician or celebrity. No doubt they delude themselves into thinking they are gods or demi-gods --

I could be wrong. Just sharing my stream of thought.
