Ah, but you don't have to do it as sci-fi. You're thinking too small - probably in the the *earthly* space-station range? If you take a Universal Standard Ringworld, like the geofiction world of Alliance is set upon, one could place all the maps the Cartographers' Guild has ever made or probably ever will make, with enough separation that an excess of mana in one "world's worth" of magical realms won't even leak over to the plain magic-free classical-greek-ish map next door. Here - I'll show you. Alliance's website is in French, and some parts of it have disappeared from the web, but there's always archive.org. Here's the geophysical explanation page, dragged from archive.org and piped through Google Translate. Rough numbers - 40,000 km wide and 1.225 billion kilometers in circumference.

Same thing without translation, if you are Francophone.

Now, it's not bending the declared theme of the map much, if you just show the whole ring off to the side, and zoom on on selected sectors.

If you wanted neighbors, you could claim you're a few degrees around from Alliance itself - there's you an ecosystem of a couple of hundred nations - not all active in play, but with judicious use of archive.org one might find details on many of them. Mind you one ought NOT get caught in the trap of rummaging through those nations, unless one were willing to set aside one's own mapmaking for many days :-)...

Ahh, but you say Thurlor meant "a space station somewhat smaller than a planet", okaaaaaay... what happens if an o'Neill cylinder is abandoned, and bug-sized human analogues develop (or are magically emplanted)? You get plenty of not-really-sci-fi, in a unique format. And a world-scale map, of sorts.

What if the cylinder was not created by science in the first place? Say, a natural moon, slagged by an errant blast of magical power in a Universal Standard Gods War scenario. If you think that such a moon got a rough treatment, well, you should see what is left of the *planet*... Say the winning deities shaped the moon-slag into a can, spun it, gassed it up, and seeded it with leftover survivors from the planet. Voila stone-age satellite dwellers. Or steampunk. aetherpunk, intelligent-saurian, gangster-era chicago-ish, venetian empire, or take-yer-pick-era.

Best? Insides of cylinders map *perfectly* on rectangular coordinates, with no distortion. No confusing projection worries!

Think outside the box... err, inside the can.
