But Garibaldi is well prepared for any assassin and the path to the throne room of the castle is blocked by his most powerful minions, including his two personal bodyguards. Logan must destroy all resistance in order to advance to the final confrontation in a battle that will decide not just the fate of the land, but the fate of all humanity!
