The Necronomicon is an ancient grimore (spell book) popularized in modern culture by fiction writer Robert Lovecraft.
It was written in 730 ad in the city of Damascus by Abdul al Azrad. The original Arabic title of the work was “Kitab al Azif” which can be roughly translated as “The Book of the Howlings of the Desert Jinn (or demons). The name, “necronomicon”, which the Latin version retains means something like things pertaining to the customs, practices, or laws of the dead. Nekros being Latin for “dead” and nomos meaning the customs, practice, or law.”
It has been called a portal to other realms of existence , but in truth is linked directly to the realm, Deamos and the population of demons.
