The Necronomicon, also known as Kitab el Azif in Arabic, was written in the early 8th century by Abdul Alhazred. Alhazred was a poet in the court of a minor nobleman in the city of Sanaá. For reasons unknown he left the city and spent ten years wandering in the deserts. During this time he visited places such as Irim; City of the Pillars, the catacombs of Egypt and the temple of Nug and Yeb in the Crimson Desert.
In his old age Alhazred lived in the great city of Damascus, where he produced the Kitab al Azif. In the long years that followed many translations of this great work have been made. The Necronomicon possesses a wide arrange of information and spells, so much so that it would be nigh-impossible to describe them all.
The more infamously known ones are: a complicated and lengthy process capable of resurrecting the dead, A formula for Mind Transference, information on the Antarctic Elder Things, information on the Great Old Ones, and even a spell to summon the All-In-One, Yog-Sothoth.
