History leaves behind more than dust. It also leaves behind “calamities.” They are the resentments of war and famine, the backlash of emperors' oaths, and the cancers growing from the wounds of the land, rampaging through the mortal world in physical form. Lin Yan is the last descendant of the Keepers of the Year, carrying a bloodline stained by infamy and the Fragmentary Annals of the Year, a book that foretells calamities. While everyone else cultivates in harmony with the seasons, he takes the unorthodox path of going against them, beginning at Major Cold and ending at Start of Spring. As he traverses the twenty-four meridians, what he slays are not demons, but wounds deep in history that are waiting to be healed.
