The Grimoire Necronomicon contains ritual forms and invocations for the daily and annual rites of the Ancients, individual rituals addressed to each of the seven main figures of myths, and most importantly, a large ritual for personal initiation. Daily rituals provide an excellent system of esoteric activities for individual practitioners. Grimoire also provides a structure for an esoteric community - the Order of the Ancient Gods - for group practices of a unique magic system.
