Yarrick: the very name carries the weight of legend, of great deeds and of wars won for the Imperium. But Sebastian Yarrick, who fought on Armageddon, who Space Marine Chapter Masters show their fealty to on bended knee, was not always Lord Commissar. He was once just a man, a newly minted officer from the ranks of the schola progenium. His first mission under the tutelage of Lord Commissar Rasp was on Mistral. Here, an uprising of barons had upset the delicate balance of power. But, as Yarrick was soon forced to learn, Mistral and Imperial politics are often murky, the truth seldom clear cut. As war engulfs the world, a plot unravels that pits old friends against one another and fashions unusual alliances. Chaos cults, the fanatical Adepta Sororitas and clandestine inquisitors all stand between Yarrick and his mission. Here is where the legend began. In this crucible was Lord Commissar Sebastian Yarrick forged in blood.

Commissar Sebastian Yarrick returns to action to defend the world of Armageddon. When the largest ork horde seen for centuries hits the hive world, the Imperial forces are faced with an overwhelming attack. As battle rages across the planet, Yarrick and his allies lead the defence, striking at the orks in a series of daring assaults. Even if it means incurring the wrath of Armageddon’s corrupt Overlord, Commissar Yarrick will not let Armageddon fall. When the ork warlord Ghazghkull Thraka dares to invade the territory of the Imperium, Commissar Yarrick finds himself in the battle that will make him a hero – the Second War for Armageddon.
