Long before the coming of the Imperium, the realm of Ultramar was ruled by Roboute Guilliman, the last Battle King of Macragge. Even after learning of his true heritage as a primarch son of the Emperor of Mankind, he strove to expand his domain as efficiently and benevolently as possible, with the XIII Legion Ultramarines as his alone to command.

As the Emperor marshals his armies to reclaim the galaxy for the glory of mankind, one by one his Space Marine Legions are reunited with their missing primarchs. The XVIII Legion are still waiting to find their true identity, unaware their own lord has been found. In the Taras Division, legionaries face annihilation as they take a last, desperate stand against a monstrous ork invasion. Meanwhile, on Nocturne, Vulkan has raised and trained a new force of warriors. Now it is the time for him to lead his sons into battle.

A galaxy burns and brother turns on brother as the conflict brought about by a beloved son’s betrayal reaches its fateful end. The Warmaster Horus has triumphed. His massive fleet at last nears Terra and the patriarchal Throne of his hated father. Many have fallen to bring this moment about; their tales are the ashes upon which the Heresy was born and prospered. Others have played their own small parts, drops in an ocean of war and blood. None of it matters. Terra looks to the skies as it raises its defences. Armies muster, heroes raise their swords, citizens cower. The war is coming. And nothing can stop it.

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?

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. 

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. 

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.

In the age of the Dark Imperium, Primarch Guilliman’s Primaris Ultramarines are a shining beacon in the darkness of war. On the Imperial Hive World of Ikara IX, Chaplain Kastor and Apothecary Polixis, brothers in blood as well as in battle, stand firm against the endless Greenskin horde. But a threat is looming. An invasion like no other assaults the broken city of Shebat, as the crazed warlord Urgork arrives to lay waste to the Imperial forces and capture a Primaris Marine for his own twisted ends. 

Gotrek and Felix: unsung heroes of the Empire, or nothing more than common thieves and murderers? The truth perhaps lies somewhere in between and depends entirely upon whom you ask.... Once companions on the greatest of adventures, Gotrek and Felix have long since gone their separate ways. Felix, married and settled, secretly craves the excitement of his youth. And when the opportunity arises, Felix embarks upon what might be his final journey. As the chaos of the End Times engulfs Kislev, Gotrek and Felix are reunited, battling the hordes of the Troll King alongside Ulrika, Snorri and Max. 

War rages in the Caradryad Sector. Worlds are falling to madness and rebellion, and the great war machine of the Imperium is moving to counter the threat. Amongst its agents is Inquisitor Covenant. Puritan, psyker, expert swordsman, he reserves an especial hatred for those of his order who would seek to harness the power of Ruin as a weapon. Summoned to an inquisitorial conclave, Covenant believes he has uncovered such a misguided agent and prepares to denounce the heretic Talicto before his fellows.

Gotrek Gurnisson was the greatest monster slayer of the age, who met his doom at the End Times. The heroic duardin stepped forth into the Realm of Chaos to fight the daemons gnawing at the world's ending and satisfy his death oath, leaving behind his companion Felix Jaeger. Now Gotrek has returned, having outlived the old gods and the Old World. Spat from the ruinous depths with his redemption unfulfilled, he emerges into the Mortal Realms, a strange new world where gods walk the earth and dark forces are ascendant. Nothing is as he remembers.

The Inquisition moves amongst mankind like an avenging shadow, striking down the enemies of humanity with uncompromising ruthlessness. When he finally corners an old foe, Inquisitor Gregor Eisenhorn is drawn into a sinister conspiracy. As events unfold and he gathers allies - and enemies - Eisenhorn faces a vast interstellar cabal and the dark power of daemons, all racing to recover an arcane text of abominable power: an ancient tome known as the Necroteuch.

Reborn in body and spirit beneath Mount Deathfire, the primarch Vulkan gathers his most trusted sons and prepares for the final part of his journey. The Legions shattered at Isstvan V have stalled the Warmaster’s advance across the galaxy, but fresh cracks are spreading through the alliance between the Iron Hands, Salamanders and Raven Guard, along with mysterious rumours of the return of Ferrus Manus. Haunted by a sense of destiny unfulfilled, Vulkan must choose between joining their war of vengeance against the traitors and following his own barely understood path all the way to the Throneworld itself.

A malevolent threat looms over the once great city of Excelsis. For as long as the treacherous Ortam Vermyre lives, civilisation is no longer safe within the Realm of Beasts. Witch Hunter Hanniver Toll must brave the deadly seas and jungles of the Taloncoast to stop Vermyre before he can reach the legendary lost city of Xoantica. For within this forgotten ruin lies an artefact of darkest sorcery that possesses the power to reshape reality itself: the Silver Shard. 

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.
