Creating adventures, supplements, and other content for Mausritter is allowed under the Mausritter Third Party Licence. This licence allows you to create and sell your own Mausritter content while adhering to the terms outlined on that page.

If you do so, you may use the "Compatible with Mausritter" logo in your work (but are not required to do so).

Declaring compatibility with Mausritter is distinct from using the Mausritter SRD. You can create content that is compatible with Mausritter without using the Mausritter SRD text, as long as you follow the terms of the Mausritter Third Party Licence.
