The first attempt to attack the orks' home world has failed, but the Imperium is not defeated yet. New, more flexible fighting teams of Adeptus Astartes have been assembled - the Death Watch. Allies from the Imperium's past have also pledged their support - the legendary Sisters of Silence, female warriors with anti-psyker powers. With new troops, and revised tactics, Koorland leads a second attack against the orks' home world. This time, the attack goes better, and Koorland is able to confront the Beast in battle. But the creature is truly a monster, more than a match for even a primarch. How can the last son of Dorn possibly prevail?
