After leaving the cartographer's shop, they all head back to the Smithy warehouses.

Most traders to the southern continent don't want coins or bullion. They want to bring back gear. Thanks to the number of awakened adventurers and artisans, the port of Musashi is a prime spot to get extremely high-quality items.
