The Lowly Merchant's Journey

(18+) The Demon King is defeated. For 500 years, the world has known peace. However, the three heroes who saved the world mysteriously vanished after the climactic battle. A governing body known as the Merchant's Guild sponsors the now-booming trade industry. Those who hold a distinguished place among their ranks are called 'Trader Kings'. Now, the three heroes are a fading legend passed down from generation to generation, with the world now ready to stand on its own two legs. This is the story of a simple trader's journey across that world.
