- About Us
Chaosium publishes acclaimed and award-winning books, roleplaying games, board games, fiction and more.
The Chaosium was founded by visionary game designer Greg Stafford in 1975. For more than forty years, Chaosium has captivated gamers, readers and mythic adventurers worldwide. Its award-winning roleplaying games, boardgames and fiction have been acclaimed as some of the most engaging and innovative of all time.
The roleplaying games RuneQuest, Call of Cthulhu, King Arthur Pendragon, HeroQuest – as well as such classic board and card games as White Bear & Red Moon (later called Dragon Pass), Nomad Gods, Arkham Horror, Credo, and Mythos all originated at Chaosium.
"The first published RPG was Dungeons & Dragons, shortly followed by some other imitative games. Chaosium, however, was never content to imitate but published games that were original in style of play, content and design. We quickly became renowned for our originality and creativity, and were responsible for introducing many things to the hobby that are standard today." - Greg Stafford
Many of Chaosium’s product lines are based upon literary sources. Most notably, H.P. Lovecraft’s 1920’s horror fiction provides the basis of Sandy Petersen’s classic Call of Cthulhu roleplaying game line. Call of Cthulhu has won so many awards that we have lost count (though we do know that there are more than 80 of them - most recently an inaugural Dragon Award at Dragon Con 2016). The Lovecraft Cthulhu Mythos also provides the inspiration for many of the books in our Chaosium Fiction line.
We also publish Basic Role Playing (BRP), the core of our roleplaying game systems, and the first to use skills based upon the d100 mechanic. Call of Cthulhu, RuneQuest and most of our other RPG lines use BRP as the basis of their rules. Once you’ve learned to play one of these, you've learned to play the others.
The Chaosium exists deep underneath the bottom of the lowest Underworld. It is the Fount of Chaos and spews forth our collective unconscious – fantasies and monstrosities alike - into our world. Artists, lunatics, and gamers are all inspired by its restless dreams. The Chaosium speaks to us:
“We are all Us.”
“You must cut the Dragon Head off yourself, take it with your left hand and make it part of you. You must slay the dragon and wield its power.”
“Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn!”
The Chaosium lets us dream the dreams of dead gods and construct the universe out of its essential runes. It lets us travel along the Lightbringers Quest to revive the murdered sun or walk the non-Euclidean pathways of R’lyeh’s nightmare corpse-city.
In this mundane and grey world, the Chaosium brings your untamed imagination to life, through role-playing games, books, board and card games, comics, and more. Guard yourself with the Elder Sign and fortify yourself with Rune Magic, it is time to begin your adventures!
