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.

Unless Oltyx acts to save his dynasty, revenge will win him only ashes. 

Phil Kelly continues his look at the life of Commander Farsight with his first campaign against the full might of the Imperium and shows how the T'au Empire's technological superiority fares against Imperial grit.

Before the being called the Emperor revealed himself, before the rise of the aeldari, before the necrontyr traded their flesh for immortal metal, the world was born in violence. Even when they inhabited bodies of flesh, Trazyn the Infinite and Orikan the Diviner were polar opposites. Trazyn, a collector of historical oddities, presides over a gallery full of the most dangerous artefacts - and people - of the galactic past. Orikan, a chronomancer without peer, draws zodiacs that predict and manipulate the future.

The Sons of Sanguinius gather in numbers not seen since the dark days of the Horus Heresy. 

Baggit is the fast-talking ratling with an eye for the big score. Clodde is the ogryn with a heart of gold and a head full of dreams. These abhuman deserters-turned-criminals operating in the city of Varangantua have crossed the wrong man for the last time—and now they’re on the run. At least, that is, until Baggit learns of a score that could pay their debts and save their skins—the Wraithbone Phoenix, a fabled treasure rumoured to be hidden aboard a voidship recently scheduled for decommission. But Baggit and Clodde aren’t the only ones with eyes on the prize.

The skitarii are the soldiers of the Machine God, the tireless legions of the Adeptus Mechanicus.

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.

On the nightmare battlefields of the far future, few foes spark more fear and dread than the Chaos Space Marines. Nurturing a hatred that is millennia-old, they attack without mercy, spreading terror and destruction in their wake. Now hell has come to Hydra Cordatus, for a massive force of terrifying Iron Warriors, the brutal assault masters of Chaos, have invaded the planet and lain siege to its mighty Imperial citadel.

The Night Lords were once among the most potent forces of the Imperium, Space Marines who used fear itself as their weapon. Now, cast adrift from the Emperor's light and hunted as heretics after their monstrous betrayal, the Night Lords clad themselves in symbols of death and fight the Long War, bringing pain and terror to all who worship the corpse-god of Terra. A summons from Warmaster Abaddon sends these rebels on a dangerous journey that leads inexorably to a conflict with the Emperor's chosen warriors, the Blood Angels.

Haunted by nightmares, surrounded by a dysfunctional crew and striving to find her place amidst a proud and insular regiment with a culture so different from her own, Etsul must guide her crew to victory. 

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.
