Long ago, the six nations fell victim to the ruthless tyranny of the Demon King and his Serpen. He burned all who opposed him and spared few. With little hope for liberation, nobles from each nation journeyed to an ancient floating city where they pleaded to the Spirits for help. Six warriors, one from each nation, were granted a powerful Serpen of their own, which they used to defeat the Demon King.
Many centuries have passed and the tradition continues as the fifty year life cycle of the Serpens will be renewed with a new generation of Serpens and riders. Young nobles from every nation will, once again, travel to the floating city with the hope of leading the world in peace.
