The Necronomicon is an ancient book of spells. It has been translated into many languages however, only one English translation exists. Simply reading it out loud will unleash powerful spells.
The Necronomicon is the single most powerful book of spells. H.P. Lovecraft and others in the 1920s studied the Necronomicon as research for their books. Despite his concerns, Ted Klein agreed to loan the only English translation to the New York City Public Library. Clark Ashton was put in charge of the exhibit. If the translations were read aloud, the consequences would be catastrophic. The spells are like sonic keys that open portals to other dimensions where the Old Ones wait to rule the Earth once more.
In the mid-1980s, the Necronomicon was put on display at the New York City Public Library from one Monday to Friday. However, on Saturday night, it was stolen by a Shuggoth under the control of the Cult of Cathulhu. The Cult used the Necronomicon to summon Cathulhu but it was defeated by the Ghostbusters. Their new ally, Alice Derleth, decided it best she took the copy back with her to Miskatonic University.
- In reality, the Necronomicon as well as the entire Cthulhu Mythos behind it, was created by H.P. Lovecraft.
