The dark blade Gruhorn, constant companion to heroes throughout the ages. Knights, rebels, and slayers—all became legend wielding this sentient blade. But, centuries after being claimed by the first hero, Gruhorn winds up in the clutches of his descendant: a greedy, greasy, bratty lout of a first prince. Even worse: when the prince falls onto the blade, Gruhorn becomes him! But is this new body a prison, or a chance for the legendary blade to become a hero himself?
