[@Nariata] I'm not sure where you posted the NPC

Also to clarify, no one at this point except my character knows what the book is, it doesn't radiate magic or anything of the sort. Its basically a spell book, along with ways to perform ancient and forgotten magic. 

The book its self is magic in a way it has more content than possible for a book of its size, and it often picks and chooses what it reveals 

Edit, forgot to throw in that it also functions as demonology and a bestiary within.
