Demons Rising

"When the demons rise...who will die?"

History tells us that in ancient Macedonia, at the behest of Alexander the Great, a group of spiritualists known as the Magians were to write the secrets of their divine spiritual power for the purposes of good. Instead, they created a plague... a book so evil, that merely reading certain passages, one could be possessed by demons. If the book is found, what would happen if it fell into the wrong hands?
