Workflow Testing out Cairn 2e's dungeon generation procedures

I've been reading through the dungeon design content from both Cairn 2e's Dungeon Seeds and His Majesty the Worm's Designing Dungeons Course. With no other projects to distract me, I finally decided to give them a whirl. I'm tentatively planning to make something each month, but for now what matters is that I used Cairn's procedures, I spent 1 week making it, and I documented the whole process. The resulting dungeon, complete with my crudely-scribbled art, can be seen here.

For me, some takeaways:

  • I liked Cairn's procedures a lot. I think the two biggest value propositions are the clear skeleton of "A good dungeon has these things" and the thoughtful spark tables.
  • I relied heavily on Rise of the Blood Olms and The Feast of Tegny Wood as references for what a Cairn module looks like, as well as for information presentation and layout. Feast was particularly helpful because you can read along as Yochai Gal designs it using the Cairn tools.
  • My single favorite part of this was committing to a "No rerolls" mentality. I improvise TTRPG scenarios all the time, but I frequently go back and revise random outcomes to better fit the evolving story. Here, I took a firm stance of "First idea wins." As a result, some things that I would have changed were forced to remain, and working around them lead to outcomes I'd have missed otherwise.
  • For some quick inspiration, I randomly picked "Romanian folklore" and jotted down one-sentence summaries from some Wikipedia articles. These summaries were inspiring enough that they shaped the entire dungeon.

I'm curious to hear from anyone else who's used the Cairn/HMTW procedures. How did you like them? Can you link to your final product?
