A small city located five miles west of the coast of Gaia and ten miles south of the Golden Trail. Being off the beaten path; this city only gets the occasional travelling merchant and caravan that knows of the cities riches. The city is prosperous and wealthy due to Black Skull Mountain that overlooks the city. The mountain contains rich and rare metal ore veins that helps the city have a natural supply of profit coming in. As far as the people, Koshiba is a very tight knit community with everyone knowing everyone else and living quite peacefully.
