The Dungeon World supplement The Perilous Wilds has an on-the-fly dungeon generator, which I use as part of Low-prep dungeons — a larval proposal. However, despite its CC-BY-SA licence, the text of that has not been available in a editable format. Until now. I have extracted the text of the dungeon generation system, converted it to Markdown, and put in online as a GitHub project.
If you just want to use, not to edit, you can download a basic PDF render of the text.
I’ve left some “see page XX” cross-references in the text, as I don’t know what best to do with them (other than pulling in text that they refer to). For now, I’ve replaced them with “CROSSREF”.
