TWO BOOKS IN ONE!!
Book One is the classic grimoire dealing with Faust Magic. Grimoires about Faust go back to the 1500's. Grand Master Blanchard gives you new insights into this type of pact magic. Making the old grimoire clear and supplying you with the original Sigils from the ancient grimoire. This is a rare grimoire with information found nowhere else.
Book Two rips open the silly practices of pacts with the devil and other such low level like practices. The stupid technique of submitting to demons, giving them your "soul" for rewards in this reality. This is covered in detail with the Faust stories and magic of the past. It is all a LIE
