Since I got so much interest in and suggestions for the area I'm working on with the last WIP map, I thought y'all might like this: Cities and towns of the Iron Valley.
I've only written anything for Cantos yet, but I'll be adding more as inspiration strikes. There is some undercity to Cantos that I want to add, but I have to better figure out how I imagine it before I do.
Incidentally, Google Docs is great for working on this stuff. Mostly the portability is nice, because I can work on things whenever I'm near a computer and not just when I'm near my local files. The instant-publish feature is a very nice bonus, and I like that it generates a PDF for ease of printing.
