You don't know how it happened. You juat don't. All you remember is that now, there are these monsters that live with you. Killers, demons, and maybe something else along the way... You should have left that spell book alone, and yet, you did not. You've dealt with them for the past 2 weeks, and so far it has been alright, albeit quite noisy...

(The monsters: Vapor, Rosemary, Baldi, Springtrap, Fogborn, Ao Oni, Uncle Samsonite, Niloticus, WYST, MX, Forest King, Fuwatti, Vita Mimic, Inkfell, Valem, PCX, Jeffery Woods, and The Stricken!)
