Heart of Decay

It is the 31st millennium. Under the benevolent leadership of the Immortal Emperor, the Imperium of Man hasstretched out across the galaxy. It is a golden age of discovery and conquest. But now, on the eve of victory, the Emperor leaves the front lines, entrusting the great crusade to his favourite son, Horus. Promoted to Warmaster, can the idealistic Horus carry out the Emperor's grand plan, or will this promotion sow the seeds of heresy amongst his brothers?

Fell times have come to the galaxy. Cadia has fallen, destroyed by the onslaught of Chaos. A Great Rift in the warp has opened, and from its depths spew daemons and the horrors of Old Night. But all hope is not lost.... A hero, long absent, has returned, and with him comes the wrath of the Ultramarines reborn. Roboute Guilliman has arisen to lead the Imperium out of darkness on a crusade the likes of which has not been seen since the fabled days of the Emperor.

As the Horus Heresy rages and the death toll rises, one more will be added to the numberless dead: Sibel Niasta, personal astropath to the First Lord of the Imperium, Malcador the Sigillite. As her end approaches, Malcador sits vigil by her bedside, and the pair discuss their friendship and what it means - how the past and present have shaped Malcador and the Imperium, and what the future holds.

The Blood Angels Chapter of Space Marines is under threat. Having obliterated all human life in the Red Scar region of space, the largest tendril of Hivefleet Leviathan ever seen in the Imperium has converged and is making relentlessly for Baal. To face this awesome foe, Commander Dante has called upon the Successor Chapters of the ancient Ninth Legion. The Sons of Sanguinius gather in numbers not seen since the dark days of the Horus Heresy. 

On the warship Messenger of Hermes, Ahzek Ahriman and his servant, Ignis, study a most unusual prisoner - a metal construct containing the consciousness of a member of a long-extinct race - the necrontyr.

As they interrogate the necron Setekh, he is also learning about them - over and over again as he uses ancient technology to relive the moment and plot his escape. Will he succeed, or will Ahriman prevail?

Following a ferocious battle against Nurgle’s hordes, Lieutenant Quiller and the crew of Titans’ Bane are trapped inside the stricken Shadowsword. With her Cadian unit half-depleted, Quiller is forced to rely upon Paragonian and Mordian replacements. Vicious infighting within the tank soon becomes as dangerous as the enemy outside. In order to survive, Quiller knows she must remind her men that loyalty, camaraderie and self-sacrifice in the name of the Emperor transcends all planetary customs and patriotism.

The skitarii are the soldiers of the Machine God, the tireless legions of the Adeptus Mechanicus. Holy warriors, they carry the word of the Omnissiah across the galaxy, destroying impure machines and spearheading the Quest for Knowledge. A discovery of ancient technology sends a skitarii legion into battle on a forge world overrun by Chaos. When a cataclysm cuts him off from his tech-priest overseers, Stroika must rally his forces and battle both corrupt machines and Chaos Space Marines.

He is known by many names - Clonelord, Manflayer, Primogenitor. He is the epitome of deceit and perversion, and feared by man and monster alike. Once the Chief Apothecary of the Emperor's Children, the madman known as Fabius Bile possesses a knowledge of genetic manipulation second to none.

When Horus fell, his Sons fell with him. A broken Legion, beset by rivalries and hunted by their erstwhile allies, the former Luna Wolves have scattered across the tortured realm of the Eye of Terror. And of Abaddon, greatest of the Warmaster's followers, nothing has been heard for many years. Until now....

The last survivors of their company, the battered remnants of the Cadian 267th trek across the deadly toxic deserts of Sanzu in search of salvation. Taking shelter in a damaged Adeptus Mechanicus facility, they think they have found a place to await reinforcements - but something lurks in the darkness, something large and dangerous and determined to kill every last Imperial Guardsman. The Morkanaut awaits....
