Abandoned as a baby, all Lin Xun had ever known was life in the sunless mine prison. His mysterious guardian, Mister Lu, never spoke much about Lin Xun's origins, only teaching him the art of runes and treating him as a servant. The gears of fate begin to turn when disaster strikes one day, destroying the only home Lin Xun has ever known. Before the mine prison is destroyed, Mister Lu thrust an old wooden box into Lin Xun's arms and tells him to go to the Ziyao Empire if he wishes to know his parentage before throwing him into an endless dark tunnel. When Lin Xun regains consciousness, he finds himself alone in the barren wastelands and discovers a strange rune brush and a mysterious old book in the box.
