What is the Ars Magica Open License?

  • The text of Ars Magica 5th Edition and its sourcebooks has been released under an open license: the Creative Commons Attribution-ShareAlike 4.0 International license (CC BY-SA 4.0). 
  • The Licensed Material is the TEXT of the game books. It does not include the the trade dress, artwork, cartography, or logos.
  • We have created a new Ars Magica Open License logo, to let fans identify their work as open license material for Ars Magica. You are permitted but not required to use this logo.
  • The open license is a COPYRIGHT license, not a TRADEMARK license; use of trademarks associated with Ars Magica may be permitted subject to conditions below.
  • There is no System Reference Document (SRD). The full text of the released books may be extracted from PDFs available for sale on our webstore in most cases. In some cases, we don't have digital text and so aren't able to provide it, as in the case of text from the oldest books that may be licensed. We'll note this situation in our releases list here, if it applies.
  • Interested parties may contact Atlas Games about licensing Ars Magica outside of the open license.

Why Release Ars Magica as Open License?

Atlas Games has had the amazing opportunity to publish Ars Magica for over three decades, supported by our devoted fan community. 5th Edition is a weighty line of over FORTY supplements, fleshing out every facet of Mythic Europe. As the stewards of this incredible piece of roleplaying history, we feel it's time to give back to our fans, and let them take the game in new directions we haven't had the resources to explore.

There's also a whole argument about copyright and RPG rules, and one point of this license is to just sidestep it. Go ahead and make a techniques/forms based magic system RPG of furry space wizards. We were not ever going to sue you, but now you can be sure that no future owners of the game could either.

This open license release of Ars Magica was just part of our crowdfunding campaign for Ars Magica Definitive Edition. Thank you to all our backers who made it possible!
