Yep, whole place is about as secure as we can make it, I think. Keeps out demons, angels, ghosts, and whatever else people have warded it against, I'm not even sure. No problem.
Yeah, there's all kinds of books lying around somewhere, here. I can just give you the basic one, though, works on most of the low-level demons. Just be careful, it works in text-form too, and we've got a couple friendly demons hanging around.
