I wrote this was an experiment with the following goals:
- To try to put together a setting that was useful for a game master using
an old school game such as B/X or Old School Essentials, or a game
inspired by them, such as Knave or Shadowdark. - To create a setting for the invertebrate ancestries I made.
- Put together something that can be used physically, as a trifold pamphlet.
- To provide something for this month's Blog Carnival, hosted by Errant Thinking, on the topic of "Tiny Epics".

Underlog - A Pocket Setting
Somewhat like our world, the creatures are about fifty times larger. The people player characters interact with are intelligent invertebrates.
This trading town is nestled in the hollow under a gargantuan log almost a mile long. At the town’s center is a giant coin monument about 7 ½ ft. tall made of an unknown alloy embedded in the bottom of the log. The coin monument also connects to other worlds. Merchants from other worlds use a ritual of travel to the coin and back.
Underlog’s inhabitants are a community of various beetloids, spiderkin¹, and giant humanoid pill bugs called “bushboars”¹.
Resources: giant snail and riding-worm herds in the lower reaches for food, leather, and snail shell.
Goods: strange fungi, aphid syrup, various alchemical materials, and herbal balms and elixirs of various sorts.
A few very odd dwarven, gnomish, and goblin traders are also based here.

Time
Above Underlog, on the surface, the Sun moves very slowly, with each day and night taking four standard months to pass.
Ecology
Underloggers depend on domesticated giant snails, cockroaches, aphids, and worms, as well as nearby plants for food.
This world’s mammals and birds are kaiju, with a skunk bigger than an ancient dragon. They all have damage reduction of 3-10, and can only be driven away, not killed. Most are completely uninterested in Underdog and its inhabitants.

My Thoughts On This Project
The core of this is the core of my general preparation for an old school elf game town. What I didn't have:
- Art: I didn't want to give up ideas for images, at least for this experiment. I'm not sure that was the right trade off, but I'm also a horrible artist, and couldn't find much art that would convey the images I imagine when I think about this place.
- A map: This would be tricky, because my thoughts on the exact geometry of the town change over time. I imagine a hollow between the bottom of the log and the rocky surface underneath covered with decomposing wood, built up with structures, with enormous web bridges or stalks to connect the two sides. In my mind's eye, there are sections of loose bark curving up the sides of the log that have further communities built up.
- Any LLM-generated content: First, I don't agree with how LLMs are trained on unlicensed material. Second, I don't see any benefit to using it when I'm already trying to mercilessly trim down my ideas to fit into the format. Every poke I've taken at using AI to generate adventures has been embarrassingly lackluster. Third, I don't think the environment needs to be tortured that badly to get ideas for a setting.
I think it would be reasonably useful, because I've already generated similar content informally for my own games. If anything, I'm concerned that I might have cut too much, but I'm also quite happy with the ideas:words ratio, even if similar things have been done before. The real test will be seeing if it's useful to game masters who aren't me, especially new game masters.
Your Thoughts On This Project
First, if you made it this far, thank you for your interest. I appreciate your time, and would also appreciate your input.
How useful would this be for a game you're running? What do you like? What's would you like to see added or changed? What would you take out to make space?
Let me know how useful it was if you end up using it at your table.
