Necronomicon is - as the title strongly implies - based on the writings of H.P. Lovecraft. The story is set in Lovecraft's fictional city Arkham somewhere in New England. It is said that a terrible ritual has taken place there, involving a woman giving birth to a demonic child. A journalist named Jonathan heads to Arkham to find out more about the dreadful rumors, and to explore the ruins of an ancient monastery. In the town, Jonathan meets other characters with their own agendas. Terrifying nightmares, like visions from the past, haunt Jonathan. Will he be able to preserve his sanity and solve the mystery?
