He waited so patiently inside the book, waiting for his time. He was trapped of course by that foul wizard but he could wait and use the time to prepare spells and rituals. Pehon didn't like being patient but if forced he could do the job oh so well. Because he knew human nature - his book would be opened and his prison walls tested. Eventually a virgin would open his book and read from the pages, and he would be free.
Now freed after thousands of years, the demon Pehon revels in his new freedom as he enacts the ideas he had in place. Now women around the city are acting strangely as Pehon is let loose As he goes on what seems like a mad quest to deflower 1,000 virgins - for when he takes the virginity he also gets their souls. Soon no virgin is safe in the city, for with all the old magics gone who can stop the Demon of a Thousand Brides?
