"Book of the Cthulhu" is book #3 in the Dark Lords' "Multiversal Metaphysics & Sorcery" series. The first half of the book is our study of the "Cthulhu Cult"-the metaphysics, mythos, philosophy, psychology, history, structure, sorcery, religion, literature and language of the Cult that will never die. This is the definitive reference for anyone would like to know more about the Cult's gods, sorcerous rituals, religious rites, esoteric agenda, R'lyehian language, core literature, or wants to create their own Cultic coven. The second half contains five core stories of Lovecraft's Mythos: "The Call of Cthulhu", "The Dunwich Horror", "The Whisperer in Darkness", "The Dreams in the Witch-House", and "The Haunter of the Dark", that introduce the new reader to the Literature and provide a convenient reference for the first half of the book.With this publication, the Dark Lords are opening yet another gateway to the Outside through which the inspired seeker may find a path to Black Gnosis and Endarkenment. In these latter days of the present world, as the ranks of the Called grow steadily and the day of Return draws near, we offer this book as another blow against the idols of this age, and a call to embrace the idols of the next one: great Cthulhu, Yog-Sothoth, Azathoth, Nyarlathotep, Shub-Niggurath and all the rest, who are beckoning us in dreams to the great holocaust of ecstasy and freedom to come.As we say in the R'lyehian tongue: Iä! Iä! Cthulhu fhtagn!
