On a continent ruled by Chaos, the Lords have the power of a Crest that can calm the Chaos and protect the people. However, before anyone realizes it, Lords cast aside their creed of quelling the Chaos and instead start to fight each other for their Crests to gain dominion over one another. Siluca Meletes, an isolated Mage who scorns the Lords for abandoning their creed, and a wandering knight named Theo who is on a journey to train to one day liberate his hometown make an everlasting oath to work together to reform the continent dominated by wars and Chaos and usher in an Age of Order!
