Saltmarsh is a relatively small port town in the south-east of the Southern Reaches . Built up by members of the merchant fleets, retired pirates and privateers, it acts as a secondary point of contact with this mysterious land. Exploration from Saltmarsh has been fairly limited, as many of the people here moved there specifically for a quieter life, however, the possibility of it becoming a trading hub is not unknown to the inhabitants.

Flanked to the south my marshy mangroves with snowcapped peaks beyond that, and grasslands to the north, the area is relatively easily defended, though thus far it has not suffered any major attacks by the inhabitants of the Southlands.

Saltmarsh was founded my a mix of merchants and privateers in the spring of 4 OS.
