The new book of Rituals from the Magical Arts of the Necronomicon.
I beg the reckless who will read this to be extremely careful; beware, you who wish to open the Gates of Time and Space in order to pray the Old Gods. They are older than this Earth, older than the most remote civilizations of UR. These gods existed before cults, before the coming of man, before the altars of sacrifices and wars. To you I say: beware! For the following will satisfy all your wishes and lusts, as good and beneficial as the most unhealthy and deplorable, all your low instincts as well as your most questionable desires. But please take heed. This wealth of knowledge is a slow poison.
These dangerous incantations were used to open Celestial Portals, temporary gates to the Earthly Dimension of men and that of Primary Beings. When used in conjunction with particular magical Characters, signatures of monstrous Entities, the Priest who knew the Text managed to come into contact with strange Spirits and dark Demons belonging to the outer Spheres of the ZONEI. Unfortunately for humanity, even today, these rituals have not lost any of their effectiveness.
The fearless Priest may, at his peril, attempt to conjure up the Ancient Names and Demons of the Tome Nergak. I will teach you how to contact this race of Spirits from the Necronomicon. But this knowledge is a curse and this curse will soon be yours.. Poor fool. May the Gods, the Great Old Ones, have mercy on your soul.
