it's about as gross as it sounds, and at least twice as bad, but... it makes me, you, us stronger. that's what got all this started, isn't it? Demon blood. It's got power in it. You get more blood, you get more power. with more power, you can exorcise demons, kill them. which you can use to break the deal.
I haven't had any since before I got here. but, yeah. i need some I use it.
