Rogal Dorn, Primarch of the Imperial Fists Legion, faces a stark reality. He must tear down the magnificence of the Emperor's Palace, a shining beacon in a galaxy of darkness, and turn it into a fortress. With the army of the Traitor Horus drawing ever closer, as he blights the Palace with gunports and defence towers, Dorn must face a difficult question: "What are you afraid of?"
