The RuneQuest-Gesellschaft e.V. was founded in 1991 at the 2nd RuneQuest Con, to foster fantasy roleplaying, the RuneQuest RPG and all related games and the setting world Glorantha. Over the years, the society became more and more international, publishing English material alongside their German products. For that, it adopted the name "Chaos Society".
Among other items, the Society publishes the Tradetalk magazine.
