Left orphaned after the Great War between kingdoms, Mathias the Second soon found himself drafted into the Merchant's Guild, a fraternity dedicated towards profiting from the carcasses left behind from battles between Heroes and monsters. But this opportunity is nothing like he imagined. With Mathias the Second now expected to dodge the jaws of a Great Wyrm, or confuse the mighty Cerberus, the lowly apprentice has grown tired of this lifestyle. Trouble soon finds them when an untested Hero falls while the Guild steals the eggs from a Great Wyrm. Upon witnessing this failure, Mathias the Second recognizes that these so-called Heroes are merely actors paying for the opportunity to defeat drugged monsters. Now forced to abandon the Silent Isles before the Church finds them, Mathias the Second and his companions leave the Conquered World behind them, sailing into unknown waters.
