here's a WIP of a map I've been playing with for a sci-fi novel.
A naturally occuring ringworld. On Janus the day is the same length as the year so one face always faces the star, the other into space so the only habitable region is a narrow 250kmwide belt around the girth of the planet.world copy.jpg
Janus was populated by the ragtag remnants of humanity after an interstellar war
Compared to some of the maps I've seen here it needs a lot of work
