This aged text feels cold to the touch, and your fingers are numb after handling it. Within its tainted pages are revealed the methods by which a person can summon forth the most heinous of creatures. Interestingly, there are also instructions on how to banish evil once summoned, should it prove too troublesome for the caster to deal with. This book would have to be used in very controlled circumstances, lest it have no effect, or worse, an uncontrolled one. Merely having it in one's possession will allow the use of a properly prepared altar.
