For a thousand years, the Sabbat Worlds have been lost to the Imperium, claimed by the dread powers of Chaos. Now, a mighty crusade seeks to return the sector to Imperial rule. And at the forefront of that crusade are Colonel-Commissar Ibram Gaunt and the Tanith First and Only - better known as Gaunt’s Ghosts. Trapped in the grinding trench warfare of Fortis Binary, the Ghosts find themselves drawn into a conspiracy to assassinate the crusade’s leader, Warmaster Macaroth.

Supreme Grand Master Azrael summons Lazarus and his Fifth Company to honour an old debt on the Knight world of Reis – a planet upon which the warp has set its hungry gaze. But Lazarus is not so sure Reis wants to be saved – its Knights are long lost, its governance is dogged by political strife, and internecine conflict hampers the world’s defence against an ancient evil. ­An evil which, like Lazarus himself, refuses to die.

After seven years of bitter war, the end has come at last for the conflict known infamously as the Horus Heresy. Terra now lies within the Warmaster’s sights, the Throneworld and the seat of his father’s rule. Horus’ desire is nothing less than the death of the Emperor of Mankind and the utter subjugation of the Imperium. He has become the ascendant vessel of Chaos and amassed a terrible army with which to enact his will and vengeance. But the way to the Throne will be hard as the primarch Rogal Dorn, the Praetorian and protector of Terra, marshals the defences.

A great darkness has befallen the galaxy, and the armies of Chaos are rampant. To survive, humanity must retaliate and take back what they have lost. By the will of the reborn primarch, Roboute Guilliman, is the Indomitus Crusade launched - a military undertaking that eclipses all others in known history. From the Throneworld of Terra does the Avenging Son hurl his fleets, their mission the very salvation of mankind.

In the hellish sprawl of Imperial Terra, Ordo Hereticus Inquisitor Erasmus Crowl serves as a stalwart protector, for even the Throneworld is not immune to the predations of its enemies. In the course of his duty, Crowl becomes embroiled in a dark conspiracy, one that leads all the way to the halls of the Imperial Palace. As he plunges deeper into the shadowy underbelly of the many palace districts, his investigation attracts the attention of hidden forces, and soon he and his acolyte Spinoza are being hunted.

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.

There are those in the great expanse of the galaxy that seek profit wherever it is to be found: the deal makers, the opportunists and explorers – the Rogue Traders. Granted power by an ancient charter, sanctioned by the Emperor Himself, these scoundrels, entrepreneurs and adventurers roam the galaxy in search of fortune and glory. None perhaps are as hungry for these twin vices as Janus Draik.

After seven long years of conflict, the Horus Heresy nears its end. But now, as the Warmaster Horus marches on Terra to rip his father from the Throne, the seat of the arch-traitor’s power lies empty. Cthonia, a world once dominated by brutal murder-gangs, is occupied by the Emperor’s praetorians—the indomitable Imperial Fists. For the Sons of Horus, this outrage demands a reckoning.

Cadia licks its wounds in the wake of the Thirteenth Black Crusade. The heretic forces retreat on all fronts. The day is won. But Lord Castellan Creed cannot rest easy. Something tells him the assault was a mere prelude to something greater, something more final. He is right. Out of the Eye of Terror comes Abaddon the Despoiler, at the head of a warhost unmatched in scale since the dread days of the Horus Heresy.

The primarch Roboute Guilliman of the Ultramarines has returned in the galaxy’s hour of need, and all muster to his Indomitus Crusade to hold back the darkness. Amongst these heroes is Cato Sicarius, Master of the Watch and vaunted captain of Second Company. Disaster befalls Sicarius and his brave warriors as their ship, the Emperor’s Will, is lost to the hellish warp, its entire crew believed slain. But Sicarius endures, though he and his men are fighting for their very survival against the denizens of the Great Rift - the daemons and renegades of Chaos.

Since the halcyon days of the Great Crusade, these noble rogue trader dynasties have plied the void in the Emperor’s name, answering to whomsoever sits as the king of the Davamir Compact. There has been profit and adventure and abundance in these times… Yet now the galaxy is changed, divided by the birth of the Great Rift. As plans are drawn up for the most immense crusade imaginable, the Emperor’s reborn son demands that the Compact seek a way across the Rift.

The feral warrior-kings of Fenris, the Space Wolves are the sons of Leman Russ. Savage heroes, few can match their ferocity in battle. After half a century apart, Space Wolves Ingvar and Gunnlaugr are reunited. Sent to defend an important shrine world from the plague-ridden Death Guard, the Grey Hunters clash with the pious Sisters of Battle—who see the Space Wolves as little better than the enemy they fight. As enemies close in around them and treachery is revealed, Gunnlaugr and his warriors must hold the defenders together.

Newly promoted to the captaincy of the Ultramarines Fourth Company, Uriel Ventris leads his warriors to the world of Pavonis, where vicious alien raiders are bringing death and destruction. As Pavonis descends into political turmoil, Uriel and his warriors must battle the xenos as they unravel a plot to unleash an ancient evil buried deep beneath the world - the mysterious and deadly Nightbringer.

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.

Ufthak Blackhawk and the green tide descend upon Hephaesto - an Adeptus Mechanicus forge world bristling with loot - only to find it already under siege by the notorious Freebooter Kaptin Badrukk. When his warboss, Da Biggest Big Mek, orders temporary co-operation, Ufthak seeks to make a name for himself by crushing some of the Imperium’s most advanced defenders and claiming the greatest prize.
