Library Heretical – Third-Party Supplementary Materials for HIS MAJESTY THE WORM

I really do believe that indie games live and die by their third-party support.
Mothership is probably the best in the business with this right now (although lots of cool games have super active, super productive communities(. Really an inspiration!
Shortly after my new-school game with old-school sensibilities game, His Majesty the Worm, was published, I asked Sean McCoy of Mothership for advice on this. He suggested I run a game jam. So I did! The Worm Jam was a success! People made all sorts of stuff: dungeons, NPC generators, fishing minigames! And since then, new third-party material has continued to flow in.
I have a dedicated space for all published third-party materials called the Library Heretical.

Submitting to the Library Heretical
His Majesty the Worm was designed to be accessible and easily hackable. As such, we’ve chosen simple language to communicate that you can create derivative or supplemental content.
I would love for the community to make content for His Majesty the Worm. Make dungeons. Make extra rules. Make alternative rules. Make monsters. Make art. Make random generators.
You can publish your content for free or sell it (without us taking a cut). You can read the text that guides this spirit of innovation here.
To help get you started making stuff, I put together this Creator’s Kit. It contains the InDesign design files, fonts, and styles that were used to make the core game. Use them to make your submissions have the same look and feel!
Last but not least, the Worm Discord is very creative space – people are putting together lots of neat stuff there!
By the way: Knock! #5 is now crowdfunding
While I have you, I wanted to mention that Knock #5 is currently on Kickstarter! Knock! is that hoary and honored old mainstay of OSR theorycraft and gameability: a bric-a-brac of adventure gaming for the true grognard connoisseur and curious D&D-heads alike.
We have surpassed 1158% of our funding goals! If you haven’t backed yet, do so now! You don’t want to miss this addition to your adventure gaming shelf.
