I came across this map while cleaning up some old files. It was a pen test with a (then-) new fountain pen from a year ago.
The image was skewed and low-contrast, and I’ve done a bit to clean it up, but it’s still sorta rough. But then, it’s a cavern, and there’s not a straight wall in sight, so who can tell if it’s a bit off or not.
As is the case with most of my maps, feel free to use this for any non-commercial purpose (with attribution). You can also contact me if you’d like to use any of my works for a commercial project.
