Luther Luttrell, a Knife Peddler Seer, descends every sixty years. Sixty years ago, he granted the ancestral blade to the Su Clan, guaranteeing prosperity. The Su Clan betrayed their agreement, attempting to seize the blade and hunt Luther Luttrell's bloodline. Luther returns to collect the debt, using divine punishment to discipline the ungrateful, protect Star Luttrell, heir of the Lu Clan, and reestablish the Knife Peddler Seers' order.
