The Cthulhu Mythos is a collection of 23 loosely connected short stories. Each story connects to the acient cosmic entities known as the Great Old Ones, buried in a deep sleep beneath the earth and incomprehensible to mankind. For the few mortals who dare to glimpse this unknowable world, the result is a complete disconnect from what was once considered reality.

First published in English in 2007 under title: The history of terrorism: from antiquity to al Qaeda.

The Cthulhu Companion is a collection of new Cthulhu mythos lore, scenarios, and rules additions to the game. From this volume the Investigators gain two new skills and a chance to encounter prehistoric monsters, find a missing uncle, stop cattle mutilations, and solve a kidnaping. The grim prisons of four continents plus new Cthulhu mythos deities, races, and monsters help the Keeper propel the Investigators to madness. Player-characters will reel from new phobias and insanity types.
