Dude this is so cool. Everything about the module feels crafted to inflict melancholy and drama as you pull yourself across the wastes. Yet there are points of light in the darkness and the potential for interactions with the other wanders are boundless. I think this is a really special one.
The font and background contrast worked for me. No readability issues.
I did feel a like the description of the hex crawl mechanics lose me a bit, but with the diagram I got what you're going for.
I don't really see a connection with the theme. The size scale is pretty massive so I struggle to see how this would be on a space station, perhaps a moon or something though?
