The story takes place on a continent ruled by chaos. The chaos breeds disaster, but the Lords of the continent have the power of "Crest" (a Mark of the Saint) that can calm the chaos and protect the people. However, one day the rulers throw away their creed of protecting the people, and instead start to fight each other with their powers to gain dominion over each other. The novels center on Silka, 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, which is under tyrannical rule. Silka and Theo make an everlasting oath to each other as master and servant, and work together to reform this continent dominated by wars and chaos.
