Ars Magica

Ars Magica is a role-playing game set in 'Mythic Europe' – a historically grounded version of Europe and the Levant around AD 1200, with the added conceit that conceptions of the world prevalent in folklore and institutions of the High Middle Ages are factual reality (a situation known informally as the "medieval

paradigm"). The players' involvement revolves around an organization of magi and their allies and foes both mundane and supernatural. The game was originally developed by Jonathan Tweet and Mark Rein-Hagen at Lion Rampant, with its first edition published in 1987. The current edition (the game's fifth) was written by

David Chart, and published in 2004 by Atlas Games, who continue to develop new material for it. A definitive edition, based on the fifth edition was crowdfunded in 2024 and shipped in 2026. In conjunction with the definitive edition, Atlas Games released the entire texts of all fifth edition books, as well as selective

supplements for third and fourth edition, under open license. Subsequently, community projects have made the complete texts available online. Ars Magica was one of the first examples of a troupe system. Early editions recommended that the players collaborate to create the campaign world and story with: Each player
