We here at Moon Design want you to be able to use HeroQuest as your rules engine for your game setting, be it science fiction, high fantasy, horror, westerns, martial arts, or anything else. To facilitate this, we are enabling you to publish your own non-Gloranthan game material using the HeroQuest rules engine without paying us royalties or negotiating cumbersome or intrusive license agreements.
We created the HeroQuest Gateway License to let you do just that. Check it out at our HeroQuest Gateway page (http://www.glorantha.com/index.php?page_id=94) and let this be your license to adventure!
