So I redid one of the rivers, added some mountain passes, and marked a couple possible sites for large urban areas. The westernmost mountain pass would be heavily guarded against incursion by the forces of the Necromaster, while the eastern pass would be important to trade through the Big City to and from the Eastern Empire. I feel like I'm just about ready to put pencil to hexpaper. Thanks again for all the great comments!
