I apologize, once again, for the incredibly late update. I actually forgot. Sorry.
Project Bloodspiller is a primarily American effort to develop weapons with a death aspect. Standard materials include fully tarnished silver and copper, and more exotic materials include iron oxide distilled from appropriate human, animal, Nephilim, or Eidolon blood.
Nearly all products are Bloodforged, and one of the more notable results is the Mortal Coilgun.
