We plan a very open license for third party content for modules for Drakar och Demoner. Basically, if you follow a few simple rules, you will be able to create and sell any module you like in English or Swedish with no royalties, as long as it requires the core game to use. A special logo will be provided to mark compatibility with Drakar och Demoner. More details about the third party license will be provided closer to the release of the game.
Quoted for convenience, and posted as a place holder until we get "closer to the release of the game".
I do have one question now: what is the meaning of "modules" - are we talking about any modular publication (adventures, settings, supplementary rules), or "modules" in the old D&D sense meaning just adventures?
