In the past, the Orc Kingdom and the Sherlock Dynasty competed for supremacy on the Old Continent, fighting so fiercely that the sky went dark and the earth dim. The war lasted for more than three hundred years; eventually, the Orc Kingdom was vanquished by the Sherlock Dynasty, which slaughtered millions of beastmen. Nevertheless, due to the centuries of war, the Sherlock Dynasty exhausted the nation's potential and was conquered by the emerging Fars Empire.
However, the Orc Kingdom had once been a top power in the Old Continent, and it was a well-known legend that the beastman nobles who were bloodily massacred had hidden much wealth before dying. In fact, some people had found the treasures hidden by the beastman nobles and became wealthy as a result.
