Welcome, sveco. Map right in the first post - worth a bit of rep just for being willing to jump in. Then too, the map is shaping up nicely - good work thus far.

To make suggestions on political divisions, it would help if you had even vague ideas about the era, setting, peoples, and such. Care to give us a brief rundown? Or are you like me, with the terrain generating the societies and peoples? I have a sort of map- first approach to world building - have you done enough to know your own preference?
