I Am a Psy Vamp
I am a psy vamp, but of an unusual caste. I feed primarily off of latent energy, but can feed off of any energy source. I have the unusual (amongst the psy vamps I have met) ability to process this energy into life energy. Food won't do it for me alone, I need this environmental source.
The problem is that this ability makes me a psionic beacon for all kinds of astral dross. Just tonight I had to deal with a lesser demon. You know, those tall, shadowy, annoying ***** that get up in your face, try to scare you, and drink in your fear energy? I grabbed it, drained it, ripped in half, and devoured its vital core.
It was pretty damn tasty, if I do say so myself.
