The five major continents and their major city-states are:
Polyhex (NW): Protihex(N), Darkmount(E), Soniplex(Central), Iacon (S)
Stanix (SW): Vilacron(NW), Fort Scyc (S of Vilacron), Tyrest (Central), Yuss (In acid wastes)
Axiom (NE): Tyger(W), Helix(Center), Gygax (E)
Crona(S): Kalis(W), Simfur(E)
Kaon (SE): Kaon (Center), Ankmor(E)
Another city-state sits on the joining of 6 skyway branches near the ruins of Crystal City called Nexus.
How's this? (I don't have a good graphics program, so I had to work with markers and a pencil.)
