I actually have an enemy for Abaddon called Obliterate. He could function as either a hero or villain (depending on what kind of light I wanted to shed on Abaddon) but never really lived past a few posts... mainly because he'd get his entrails torn out and hung on a wall as a decoration. I can write him up if you ever need more NPCs.
