Refurbished Content: Electric Bastionland
In February, I wrapped up an 8-session campaign of Electric Bastionland. As part of my prep I made up an underground for the Borough my players were based in, but in the end they never visited it. I quite liked some bits, so here it is.1 Drop it into your own Electric Bastionland setting, or use it as a dungeon in some other system.

Here's a Google Drive link, which also includes a PDF export. This was made in draw.io. The diagram is embedded in each file, so you can take a copy, import it into draw.io, and edit it how you like.
Tried to cram as much into this one page as I could, so only the tables include statlines. I'm sure you can improvise the rest.
The original was much rougher & had missing table entries; I've been polishing it on and off since late August to get it in a state I was happy to show to people.↩
