Nice. One initial thought though is this given that the capital is located at the divide of this river I would imagine that there would be docks on both sides of the city so as to facilitate trade from either direction. Then again, now that I look at Carbus's map, the only major urban ceter to the West of Greanos is the Necromancers Castle, and don't have any idea if the city would be on friendly terms with someone like that, so scratch that. At any rate, looking forward to seeing this fleshed out.
