The Grand Grimoire, often known as the “Red Dragon” or the “Gospel of Satan”, is a medieval spellbook reputed to hold incredible power. It is said to be the work of a mysterious figure called Honorius of Thebes, who supposedly channeled the Devil to write it. It ranks as one of the most powerful occult books available and is said to include instructions on how to summon demons.

This spellbook is commonly considered to originate from the 16th century. However, during the 18th century’s French “grimoire craze”, a version of the Grand Grimoire was created and subsequently published in the next century. The original Grand Grimoire, or perhaps a duplicate, is reportedly stored in the Vatican Secret Archives, inaccessible to the public.
