The Horus Heresy

Before the Warmaster's betrayal, the primarchs and their Legions were a warrior brotherhood without equal. At Calth, a planetary jewel in Ultramar's crown, a great mustering is taking place. Two proud Legions gather in hopes of healing the discord after the notorious shaming of the Word Bearers at Monarchia. Captain Alcaeus of the Ultramarines plans on joining the muster but will not rest until the remnants of the Ghaslakh Empire are purged utterly from the galaxy, For honour and glory, he has sworn an oath to succeed.

Even as the Imperium faces the renegade Legions of the Warmaster, the ruling Council of Terra is becoming paralysed from within by petty bureaucracy. Fabricator General Kane has seen his fellow Mechanicum adepts dismissed again and again by the High Lords - with his traitorous predecessor Kelbor-Hal still at large on the Red Planet, the political status of the tech-priesthood remains ambiguous. New alliances must be forged from the old if Mars and Terra are to survive the final battle.

Shortly after the shameful events of Monarchia, the Word Bearers Legion have begun to prosecute the Great Crusade with a previously unseen level of zealotry and aggression. The world of Forty-Seven Sixteen falls into their sights, a world where the human populace worship graven idols in their heathen rights and yet plead to be integrated into the wider Imperium.

As the Great Crusade sweeps across the galaxy, the forces of the Imperium encounter a world held in thrall by the alien eldar. While the Iron Hands of Ferrus Manus and Mortarion's Death Guard battle against the hated xenos, it is the Salamanders who brave the deepest and most deadly jungles, encountering monstrous reptilian beasts and foul witchery along the way. Ultimately, it falls to their primarch Vulkan himself to thwart the sinister designs of the eldar, if the Legions are to liberate this world and bring illumination to its inhabitants.

After the war to save Ultramar from the traitor hosts of Horus ended, formerly disgraced Ultramarines Sergeant Aenoid Thiel believes that enemies still linger within the borders of the empire. Finding other men of purpose, fellow Space Marines known as the ‘Red-Marked’, Thiel wages a guerrilla war to root out these enemies and vanquish them for good. Following the threads of a previous mission, the Red-Marked arrive on the moon of Bael. There they find an underwater rigging station that has seemingly been abandoned.

Charged with a solemn duty by the primarch himself, Forgefather T'kell of the Salamanders prepares for what may well be his final journey. Along with a chosen few of the Legion's elite Firedrakes, he must bear the last seven of Vulkan's greatest weapons away to the secret vault known as the Wrought, putting them forever beyond the reach of treacherous enemy and well-intentioned ally alike.

After the destruction of the Infidus Imperator, Kor Phaeron of the Word Bearers brought his followers to supposed safety in the Eye of Terror. However, their newly adopted home, the daemon world Sicarus, is far from the sanctuary they imagined - the twisted hordes of the Kairic Adept Larazzar seek to crush these newcomers and all who would ally with them. Only in the ancient legends of Sicarus can their salvation be found, but is Kor Phaeron the one to lead them to it?

As Lord Commander Primus, Eidolon leads the Emperor's Children in the absence of his primarch - who even knows where the daemon prince Fulgrim resides now? But a challenge from within the Legion forces Eidolon to confront one of his rivals, the ambitious Archorian, a capable officer and tactician who would see the Legion returned to glory. Dissent is unacceptable. It is time for the Kakophoni to be set against their erstwhile brethren.

When Horus' treachery was declared, the Iron Hands primarch Ferrus Manus sped to the Isstvan system with his elite forces to confront the traitors...and fell into their trap, losing the battle and his life. The X Legion warship Veritas Ferrum arrives in the Isstvan system in the second wave of Imperial forces. Battered by the foes and forced to retreat, the crew must make a difficult choice when survivors of the massacre ask for aid. Has the nascent war already started to claim the humanity of those involved?

The Dark Angels Legion is couched in layers of mystery and secrecy, harkening back to the days of the knightly orders of Caliban that helped to raise their infant primarch. But Lion El'Jonson's greatest strength often proves to be one of the most divisive issues amongst his sons - rarely can any two commanders agree upon one single course of action from the start. As they seek to bring the world of Byzanthis to compliance, Chapter Masters Astelan and Belath are among those with very different notions of what victory might require.

Amon Tauromachian, one of the Emperor's elite Custodian Guard, returns to the Imperial Palace after a year on one of the Blood Games by which these exalted heroes train. Tasked with a new mission, he is sent to the hives of Hy Brasil to check on the loyalty of a notorious troublemaker. With the galaxy at war and half the Imperium's armies in rebellion, any hint of heresy on the Throneworld must be stamped out.

Chagrined by his defeat at the hands of Jaghatai Khan, Mortarion abandons the pursuit of the White Scars and instead leads the Death Guard in a spiteful, punitive rampage across the systems of the Prosperine empire. World after world has fallen to this horrific onslaught, and yet the insular and secretive primarch seems preoccupied by some other unspoken goal. Finally, on Terathalion, the truth of Mortarion's sinister heritage will be exposed, and the future of the XIV Legion will be written....

Renowned as one of the finest duellists the galaxy has ever known, Lucius seeks ever greater challenges against which to test himself. After the Emperor's Children Legion scattered in the wake of their primarch's apotheosis on Iydris, he finds his way into the domain of a similarly legendary swordsman - Sanakht of the Thousand Sons. But which of these infamous warriors carries the greater favour amongst their new masters?

As war continues to ravage the galaxy, the new Age of Darkness sees whole systems simply lost and countless battles forgotten. Surely there can be no hope for peace, forgiveness or respite in such times, and all that will be left are the dying warp-echoes of supreme galactic ruin....

Fighting alongside the Raven Guard Legion, Marcus Valerius of the Therion Cohort has long scorned those who seek to deify the Emperor. But recent events have made him doubt his cast-iron convictions, and as his forces lines up against an overwhelming enemy force, a flash of inspiration leads him to question whether or not there are greater forces at work in the universe....

In the fighting pits of the Conqueror, Khârn and his fellow World Eaters compete in ever-bloodier contests of carnage and mayhem. As the Butcher's Nails dig ever deeper into their brains, the Legion have forsaken the Crimson Path. Now they walk a darker, more dangerous road: the Eightfold Path.

Soon after word reached Terra of Horus' nascent rebellion, Mars fell. Rogue elements within the Mechanicum priesthood, stirred by the Warmaster's promises of independence and prosperity, turned against the Imperium and forced the primarch, Rogal Dorn, to order an impenetrable blockade of the Red Planet. Now it has become clear that the corruption has spread too deep, and that more drastic measures must be taken if the Forge World Principal is to be reclaimed.

For a select few amongst the First Legion, the Northwilds of Caliban hold a particularly dark secret. At the command of Luther himself, young Librarian Zahariel accompanies the Lord Cypher on one of his mysterious forays into the unknown depths. But an ancient evil is stirring once more and, with rumours of galactic civil war creeping back to their home world, it may have already sunk its claws into the Dark Angels Legion....

After Fulgrim's ascension to daemonhood at Iydris, Perturabo and his Legion were trapped by the singularity at the heart of the so-called 'Eye of Terror'. Their only option? To thread the needle, and dive into the heart of the black hole. Perhaps by sheer blind luck, they were transported far across the warp to the Tallarn System but the Navigators in service to the Iron Warriors fleet were irreversibly corrupted by that harrowing experience.

Though he knows such beliefs are forbidden, Vice-Caesari Marcus Valerius of the Therion Cohort is willing to lay down his life in service to the immortal God-Emperor, for the good of all mankind. Sent by Corax to the great slaughter at Beta-Garmon, every last one of the Imperial Army soldiers under his command knows that the end is nigh - but can Valerius' holy visions guide them to one final victory over the hordes of the hated Arch-traitor?
