H.P.Lovecrafts motivgebender Mythos "Written mostly in the 1920s and '30s, Lovecraft's work builds a somewhat rickety bridge between the florid decadence of fin de siecle fantasy and the more "rational" demands of the new century's science fiction. His early writing is gaudy Gothic pastiche, but in his mature Chtulhu tales, Lovecraft adopts a pseudodocumentary style that utilizes the language of journalism, scholarship, and science to construct a realistic and measured prose voice which then explodes into feverish, adjectival horror. Some find Lovecraft's intensity atrociousănot everyone can enjoy a writer capable of comparing a strange light to "a glutted swarm of corpse-fed fireflies dancing hellish sarabands over an accursed marsh."  

Erik Davis: "Calling Cthulhu -H.P. Lovecraft's Magick Realism"
"Call of Cthulhu is one of the oldest games out there; it may be the oldest horror RPG currently published. It has an incredibly loyal following, and understandably so. Properly run, it is eerie, disturbing, and inspires a deepseated desire to turn as many lights on as can be found.
Set in the 1920's, CoC involves the player characters as (sometimes unwilling) investigators of the supernatural. Frequently these investigations reveal enormous, barely-comprehensible conspiracies wrapped around ancient beings of incredible power and horrific evil. These beings (from the writings and deranged imagination of H.P. Lovecraft, whose short story The Call of Cthulhu is, obviously, the source of the game's name) are often referred to as the Old Ones or the Great Old Ones or the like; as far as I can tell they are a bunch of hideous, warped, ugly bastards who used to rule the world until they were imprisoned. "
"I don't know who imprisoned them, I don't know when, I don't know why. The main fun of CoC comes from the sheer unreasoning terror you feel when you roleplay an ordinary person in the 1920s who has absolutely no idea what's going on."

Cthulhu in R'lyeh
"Die Alten waren, die Alten sind und die Alten werden sein. Nach dem Sommer kommt der Winter und nach dem Winter der Sommer.
Früher regierten sie dort, wo heute der Mensch herrscht; wo heut der Mensch herrscht, werden sie wieder regieren.
Nicht in den Sphären, die wir kennen, sondern dazwischen warten sie, friedlich und unerschütterlich, für uns unsichtbar und ohne Dimension."
"Das Necronomicon", zit. in R.A.Wilson: "Masken der Illuminaten", Basel 1983  
"Alle meine Geschichten basieren auf der fundamentalen Annahme, daß die menschlichen Gesetze, Interessen und Gefühle im Universum als solches keinerlei Bedeutung oder Nutzen haben."  
"Ph'nglui mglw'nafh Cthulhu R'lyeh wagn'nagl fhtagn.
In seinem Haus in R'lyeh wartet träumend der grosse Cthulhu"
