I've been pondering the world map, in particular travel times and time zones (I may be over-thinking this...) but there's a problem. Namely, the map as it works in FFVII the game is totally borked. It maps on a torus rather than a sphere, and as far as I'm aware there's no way to make the two equivalent.
I'd actually rather like to see if I could make a vaguely sensible spherical interpretation of the FFVII world, but it might take a little time and would be strictly non-canon (and probably make a mockery of the canonically very short travel times in FFVII - start of the game to end is supposed to be just over six weeks!). If people are willing to accept it for the RP though, I'll see what I can do.
(Moral of this thread: FFVII background is a terrible, inconsistent mess
