If you want to trade past that river, be my guest. But I'm standing firm with what I said. That scrap of and that seperates the river from the bay is part of the Myrari Republic, so you'll have to go to war with me if you plan to build there.

A canal would improve your trade and income too. if you put a slight and reasonable tax for traveling through the river, you would get a lot of income from the trade between me and north. It would also connect Bigwall to the river and make it a trading city between you and me.
