Demons and devils are all around us at a ration of 3 to 1. They walk in hoards in the streets like zombies. They jump onto your back and scream obscenities to try and tempt you to do their will. Houses are theirs. They stake claim to a dark place and take hold of it. This may be a house, a dark alley, or your own body. They feed on your energy. They will destroy you if they can. It is essential to know how to ward them off when they attack. Possession, infiltration, attack.
