A few days ago I mentioned the canal connecting the Trident to the God’s Eye allowing the entire Riverlands to ship grain and goods down the Blackwater Rush to King’s Landing. However, I actually meant that they could be shipped down the God’s Eye River (it isn’t given an actual name in the books). However, I have a topographical map from “The Lands of Ice and Fire,” and this river appears to be as large if not larger than the Blackwater Rush. Sorry about the mistake:(
