Fan-Use and Licensing
Chaosium offers fan-use and licensing opportunities for individuals, small publishers and commercial partners, both in English and in foreign languages. If you are a Chaosium fan and keen to share your content, or interested in working in partnership with us as a professional licensee, please look at these policy descriptions to see which would work best for you.
Fan Material Policy
We support and value the contributions of the wider Chaosium Tribe. We love to engage people with our mythic stories, and we want you to be able to share yours too! Our Fan Material Policy is designed to do just that while respecting ownership of our copyrights, trademarks, and other intellectual properties.
Small Publisher Limited License
Our Limited License offers small publishers and individuals the opportunity to produce limited run game material for use with any of our game lines. This could include fanzines, convention scenarios, and one-off books. These can be commercial products, but gross sales revenue should not exceed USD$2000 per annum (per year).
Chaosium works with a wide range of commercial licensing partners who produce products to supplement and support our own. This includes board games, card games, certain RPG supplements, dice, computer games, and foreign language editions. These all operate under our Commercial License. Such licenses are for officially approved product and require ongoing management, regular reporting, and close work with our line editors. Accordingly, we are selective about who we partner with, and initial approaches require a detailed business plan. These commercial licenses also have specified release and revenue targets.
The Miskatonic Repository
The Miskatonic Repository is an official online collection of user-made content (hosted on DriveThruRPG), allowing creators to sell their own original Call of Cthulhu material. Creators can make money from their published community content, or make it freely available – it is entirely up to the creator.
Interested? Go here to see what is on sale now, or go here to see the guidelines. The Miskatonic Repository is a separate element from our licensing structure – it operates separately in parallel. A Chaosium licensee can also have content on offer in the Miskatonic Repository.
HeroQuest Gateway License (HeroQuest Rules Engine)
The HeroQuest Gateway License is a non-exclusive, non-transferable, royalty-free, worldwide license to enable game designers to use Moon Design Publications’ HeroQuest rules engine for their game settings, whether it be science fiction, high fantasy, horror, westerns, martial arts, or anything else (apart from Glorantha).

General Note on Fan-Use and Licenses
Note, we have a number of exclusive license agreements already in place for certain game lines, or types of products, or for products in certain foreign languages. This means it may simply not be possible to grant you the license you want at the present time, even if your proposal has great merit. We may also already have similar projects under consideration or in the works ourselves. It is our discretion whether we grant you a license or not.
All material covered under these policies, as well as their advertising, promotions, press releases, or other affiliated documents must not contain racist, homophobic, discriminatory, or other repugnant views; overt political agendas or views; sensationalist or distasteful depictions or descriptions of criminal violence against children; rape or other acts of criminal perversion; or other obscene material, without the express written permission of Chaosium Inc.
