I can barely remember it anymore. That's the only real part I remember, which I suppose proves your point.
I got supplies through the tesseract; I have an anti-possession charm I can give you. You can also get a symbol tattooed on your skin to make it more permanent. But it's not as present a danger as you might think. In the time I've been here I've only seen two demons come through, and they made the choice to follow the rules of this place.
No problem. I'd offer to teach you myself, but I don't really have enough time to devote to it.
