Open00 License

Back to the Mud is an independent production by Michael Davison and is not affiliated with Open Ended Games, Inc. It is published under the Powered by Open00 Third Party License.

You can find the full license for the Open00 System here. However, the most relevant (for my purposes) are below.

The Open00 System has been written with the fantastic community of TTRPG content creators in mind. Since the beginning we wanted you to be able to create and publish your adventures, rules expansions, and other content freely.

The awesome people of Mörk Borg came to our rescue, kindly letting us use their third party license (https://morkborg.com/license/) as a reference to write our own. And thus, the Powered by Open00 license was born.

The following license allows anyone to create content for the Open00 System without having to ask for our permission.

You can distribute your creations for free or sell them. It’s totally up to you and you won’t owe us anything. There are just a few rules to be followed:

  3. The mechanics and game rules of Against the Darkmaster may be reused and referenced freely. You can also use the names of creatures, locations, and entities of the game world.
