Ferrus Manus, primarch of the Iron Hands, employs his brutal methods of war to bring a world to heel in the Emperor's name. The Great Crusade has swept across half the galaxy, a million human worlds now embracing the truth and reason that comes with allegiance to the rule of Terra. But even such unparalleled success comes at a cost. Rumours abound that the Emperor plans to step back from the Crusade and raise one of his primarch sons to lead in his stead. Faced with the bitterly non-compliant human empire of Gardinaal and a leaderless host of Ultramarines, Thousand Sons and Emperor’s Children at his Legion’s command, the Iron Hands primarch Ferrus Manus decides to make an example that even the Emperor cannot ignore.

Amongst the Adeptus Astartes there are few warriors so utterly committed to the Imperium and the service of mankind than the Iron Hands. With their conviction comes contempt for any show of weakness and a determination to expunge it whatever the cost. Original.

Includes an excerpt from "Angel of Fire" by William King.

The sixth title in The Horus Heresy: Primarchs series, focusing on Fulgrim, primarch of the Emperor's Children Legion. Lord of Chemos and bearer of the Palatine Aquila, Fulgrim, primarch of the Emperor’s Children, is determined to take his rightful place in the Great Crusade, whatever the cost. A swordsman without equal, the Phoenician has long studied the art of war and grows impatient to put his skills, and those of his loyal followers, to a true test. Now, accompanied by only seven of his finest warriors, he seeks to bring a rebellious world into compliance, by any means necessary. But Fulgrim soon learns that no victory come without cost, and the greater the triumph, the greater the price one must pay...

Created in the Emperor's own image, the primarchs had long thought themselves to be princes of the universe and masters of their own destiny--they led the Space Marine Legions in glorious conquest of the galaxy, and no enemy of the Imperium could stand against them. However, even amongst this legendary brotherhood, the seeds of dissent has been sown long before the treacherous Warmaster Horus declared his grand heresy. Gathered within this anthology are four novellas focusing on some of the mightiest warriors and leaders that mankind has ever known--Fulgrim, Ferrus Manus, Lion El'Jonson and the twin primarchs Alpharious and Omegon--and the roles that they may have yet to play in war which threatens to change the face of the Imperium forever.

Placed in command of a Legion he does not want, in service to a father he cannot forgive, Angron gives an ultimatum to his children, one that will set them down a path from which they can never return… As the Emperor travels the galaxy at the head of his Great Crusade, few events are as important as rediscovering his scattered sons, the Primarchs, and bestowing them as the masters of their Legions. United, a Legion becomes a reflection of its Primarch, both in his strengths and his flaws. For the Twelfth Legion, once the War Hounds and now the World Eaters, the line between strength and flaw is almost impossible to separate. Desperate for his acknowledgement, will the World Eaters follow their father and cast themselves in his broken image or will they resist? And will any of them ever learn who their father was truly meant to be?

In the wake of the Dropsite Massacre at Isstvan V, the survivors of the Salamanders Legion searched long and hard for their fallen primarch, but to no avail. Little did they know that while Vulkan might have wished himself dead, he lives still. As the war continues without him, all eyes turn to Ultramar and Guilliman's new empire there, and Vulkan's sons are drawn into an insidious plot to end the Heresy by the most underhand means imaginable.
