Chaosium, (kay-OSS-ee-yum) is known for publishing high quality books and games, and for having a well-developed sense of fun. In 1975 the company was founded as The Chaosium by Greg Stafford, visionary game designer and creator of the world of Glorantha and the Pendragon roleplaying game, among others. Most of Chaosium's product lines are based upon literary sources. H.P. Lovecraft's 1920's horror fiction provides the basis of Sandy Petersen's classic Call of Cthulhu roleplaying game line which has won so many awards that the we have lost count, though we do know that there are more than 80 of them. Mr. Lovecraft also provides the inspiration for many of the books in our Chaosium Fiction line. We also publish Basic Roleplaying, the core of our roleplaying game systems, and hundreds of game supplements, both in print and downloadable formats.
