Some debts can only be paid in blood. After ten years in exile, the Prince of the Club Confederacy walks the streets of the Diamond Empire once more, hidden amongst people. Arthur slays monsters and people alike under the moniker of the Deathwalker, seeking a truth that was stolen from his very mind. Accompanying him on his hunt for revenge is Maisha, a bone shaman whose visions of a monstrous serpent come to fruition when Arthur stumbles upon her village and becomes a prisoner. Meanwhile, the Diamond Empire continues its conquest for land and resources. Civil unrest grips the empire's furthest reaches as rebels from the occupied Syndicate of Spades spread death and fear around the world, and the passing years have done nothing to quell their bloodshed. The Spades can burn everything to the ground for all Arthur cares. He just wants their king, and Maisha just wants her freedom.
