Choral the Conquerer’s rough-and-tumble capital at New Stetven is a bustling trade city despite the recent collapse of its aristocrats. Grain, fish, timber, and ore flow from Brevoy through New Stetven and out to the rest of the north. The food from Brevoy sustains much of the River Kingdoms, Numeria, and Mendev, where constant bandit raids and invading demonic armies make farming difficult, and most of that food passes through New Stetven. In return, exotic goods from all corners of Avistan (and beyond) flow back up the Sellen River to New Stetven. Although bandits and robbers in the River Kingdoms are still a serious obstacle, the market nevertheless offers a wide variety of goods, from Numerian skymetal to Osiriani relics.
