Kharn the Betrayer takes to the field of battle as the champion of his old comrade Argus Brond, but his own motives go far beyond the petty squabbling of rival Chaos warlords....

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.

On a world besieged by the forces of Chaos, the Emperor's Children and the World Eaters are forced into an uneasy alliance when the bodies of the fallen start to go missing....

The daemon prince Mortarion has emerged from the Eye of Terror at the head of a vast plague-horde, intent upon the corruption of the Imperium he once served. Under Supreme Grand Master Geronitan, the Grey Knights finally meet the daemon army in battle on the plains of Kornovin - a mobilisation of the Chapter the likes of which few have ever seen. Kaldor Draigo and his fellow brotherhood masters lead from the front, trusting to their lord's secretive plan...until Geronitan is unexpectedly struck down by the Death Lord.

In the aftermath of battle, Flesh Tearers Chapter Master Amit picks his way across the blasted landscape and is drawn into single combat with a survivor of the enemy force, a berserker dedicated to the Blood God. As they fight, Amit begins to realise that at slaughter's end, he and the servant of Khorne are not so dissimilar.

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?

Lupercalia burns, the might of the Traitor Legions reducing the last redoubt of the Sons of Horus to rubble. And through the ruins strides Apothecary Fabius of the Emperor's Children, with an army of vile genetic experiments. But what does the twisted Apothecary want in the temple to the fallen primarch Horus? And will he find it?

Of all the Emperor’s sons who fell to Chaos, it is perhaps Magnus the Red whose tale is the most tragic. Sanctioned because of his desire for knowledge, chastised, judged, and shattered to his very elements – there is much for the Crimson King to feel vengeful for. Yet revenge is not the only thing that draws him to Terra alongside the Warmaster’s besieging armies. He seeks something, a fragment, the missing piece of himself that lies within the most impregnable place on the planet – the inner sanctum of the Imperial Palace.

Once a loyal son of the Emperor's Children, Fabius Bile now loathes those he once called brother. But when a former comrade requests his aid on a mission he cannot refuse, Bile is drawn once more into the sinister machinations of his former Legion. Now, accompanied by new allies and old enemies alike, Fabius Bile must travel deep into the wilds of the Eastern Fringe, in search of a world unlike any other. A world which might hold the key to his very survival. A world called Solemnace....

For long years, the Horus Heresy has ground on. Now, the Death Guard have been sent to begin the final battle. But Mortarion and his sons must face their gravest challenge first - for Nurgle has claimed them as his own, and he will not be denied.... The skies darken over Terra as the final battle for the Throne looms ever closer.... As the Traitor primarchs muster to the Warmaster’s banner, it is Mortarion who is sent ahead as the vanguard of the Traitor forces. But as he and his warriors make way, they become lost in the warp and stricken by a terrible plague. 

Legend tells of a foolhardy expedition, led by the radical Magos Telok, that ventured out into the unknown space beyond the Halo Worlds in search of the 'Breath of the Gods' - an arcane device with the power to unmake and reshape the very stars themselves. Thousands of years later, the ambitious Lexell Kotov musters his Adeptus Mechanicus Explorator fleet and sets out to follow in mad old Telok's footsteps. 

The Cadian Gate is broken, and the Imperium is riven in two. The might of the Traitor Legions, kept shackled for millennia behind walls of iron and sorcery, has been unleashed on a darkening galaxy. Among those seeking vengeance on the Corpse Emperor’s faltering realm are the Death Guard, once proud crusaders of the Legiones Astartes, now debased creatures of terror and contagion. 

For many long years, Gabriel Seth has led the Flesh Tearers to war. Master of a dwindling Chapter, he has made many enemies in his unceasing battle to keep his warriors alive - and now those enemies conspire against him, luring him to a remote world in order to end his leadership and life in the most violent and bloody way possible: Gabriel Seth is to be assassinated. But can even an Eversor Assassin kill one of the deadliest warriors in the entire Imperium?

In the void and upon the worlds of Greater Ultramar, the battle for the Imperium continues. Intent on rebuilding his home realm and using it as a base to reconstruct the ravaged stellar empire of mankind, the returned primarch, Roboute Guilliman, proceeds with his war to drive Mortarion and his Death Guard Traitor Legion from the domain of the Ultramarines. But when Guilliman brings his brother to battle upon the diseased plains of Parmenio, the intervention of a greater power in their fraternal struggle threatens to upend the Imperial Regent’s understanding of the galaxy. 

Exile to the miserable world of Sedh, the disgraced Necron Lord Oltyx is consumed with bitterness. Once heir to the throne of a dynasty, he now commands nothing but a dwindling garrison of warriors, in a never-ending struggle against Ork invaders. Oltyx can think of nothing but the prospect of vengeance against his betrayers, and the reclamation of his birthright. But the Orks are merely the harbingers of a truly unstoppable force. Unless Oltyx acts to save his dynasty, revenge will win him only ashes.
