The Horus Heresy

For more than 200 years, the armies of the Emperor of Mankind fought to reconquer the galaxy - led by the superhuman primarchs, the Space Marine Legions brought countless worlds back under the rule of ancient Terra. Now Horus, once honoured Warmaster and favoured son of the Emperor, has been corrupted by the whispered promises of Chaos. At his command the Imperium is torn apart by a terrible and bloody civil war, the likes of which the galaxy has never seen....

Stranger things than xenos and mutants dwell in the dark places between the stars - things known only too well to the inhabitants of Davin. Cult priest Thoros calls upon the favour of his patron gods to aid him in casting out the pretenders and non-believers, for only the true disciples of Chaos can be allowed to rule the galaxy....

The Dark Angels and the Night Lords fought one another to a bloody stalemate during the Thramas Crusade, leaving the First Legion scattered and under-strength. Back on Caliban, those Dark Angels loyal to Luther begin to grow impatient for a return to past glories, allowing the corruption at the world's heart to spread.

Though the Word Bearers' attack on Calth and the subsequent Shadow Crusade into Ultramar are but a memory, the borders of Imperium Secundus are far from secure. Sergeant Aeonid Thiel, stranded on the garrison world of Oran on his way back to Macragge, frustrates his superiors once again by pointing out the holes in their defence - traitor warband activity is increasing, and a series of key listening posts have fallen silent.

In spite of the corruption of Corax's plans to rebuild his Legion after the Dropsite Massacre, the surviving Raven Guard remain defiant. Happening upon a stricken Word Bearers vessel far behind the front lines, they find evidence of a new alliance between the traitors and the forge world of Constanix II. With rumours of terrifying new war machines stalking battlefields across the sector, it is a threat too great to ignore.

The Navigator Nisha Andrasta has served the XIIth Legion for over a century. She saw the War Hounds reunited with their progenitor, Lord Angron. She witnessed the rebirth of the Legion as the World Eaters. She looked on in confusion and horror as the primarch joined Horus's rebellion, and now she has seen him betrayed by Lorgar Aurelian, becoming the maddened monster he was always destined to be.

In its earliest days, the III Legion was blighted by a genetic flaw that threatened to end the Phoenician's bloodline forever. Fortunately, through tireless effort and the miracle of the primarch's own genetic perfection, visionaries like Apothecary Fabius were able to halt the corruption and restore the Emperor's Children to their former glory. Except, it would seem, that a terrible secret has been kept from the rest of the Legion, and the threat of further degeneration is quite real....

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.

With the discovery of the lost primarch Angron came violence and confusion, and what should have been the defining moment of the War Hounds Legion instead became a humbling embarrassment. As their senior officers fall one by one to the rage of the newly freed gladiator-king, it seems that they are doomed - perhaps their last chance for redemption comes in the form of the Eighth Captain, Khârn. Will this calm and level-headed warrior be able to lead his father into the Emperor's light, or will he join the rest of his Legion in death?

Caught by the renegade forces of the Alpha Legion and forced to take refuge in the Alaxxes Nebula, the Space Wolves are bloodied but unbowed. The young pack leader Bjorn - now known to his warriors as 'the One-Handed' - is desperate to recover his honour in battle, but replacing lost limbs for proud legionaries is not a task worthy of the Iron Priests. If Bjorn is to fight again, then he must seek out new claws for himself and christen them in the blood of the traitors....

Long ago, the primarch Lorgar was humbled by his brother Guilliman for his belief in the Emperor's divinity. Led down a dark road by this shaming, Lorgar embraced Chaos. Now, he and his Word Bearers rampage across Guilliman's realm, burning his 500 worlds in the name of their new gods. But on such world, Lorgar finds a mystery that brings his past into the present and shines a new light on his endeavours. It seems that Lorgar's legacy may be greater than even he could have ever imagined....

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.

The Thousand Sons - a Legion whose destiny was irrevocably altered at Prospero, and yet who now seem to dance only to fate's tune. Ahzek Ahriman and Magnus the Red cast their psychic sight over the galaxy, seeking any clue as to what the future might hold and where their true allegiance should ultimately be placed.

Nathaniel Garro, knight errant and agent of the Sigillite, returns from the battlefields of Calth to find a new mission already waiting for him - a ragged fleet of Space Marines from several Legions lingers at the edge of the Terran system. With the presence of World Eaters and Emperor's Children causing concern among the loyalist defenders and drawing a grim parallel with his own frantic flight, Garro must look beneath the obvious if he is to determine friend from foe....

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....

For more than 200 years, the armies of the Emperor of Mankind fought to reconquer the galaxy - led by the superhuman primarchs, the Space Marine Legions brought countless worlds back under the rule of ancient Terra. Now Horus, once honoured Warmaster and favoured son of the Emperor, has been corrupted by the whispered promises of Chaos. At his command the Imperium is torn apart by a terrible and bloody civil war, the likes of which the galaxy has never seen....

After the horrors of the Dropsite Massacre, the Raven Guard are trying to survive in the caves and mountains of Isstvan V. Their plight is desperate, and escape from the roaming Chaos Legions seems impossible. Can they hold out against the forces of the World Eaters long enough to reach an unlikely salvation?

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.

After the horrors of Isstvan, the XVIth Legion destroyer-class Grey Talon now flies under a loyalist crew on a campaign of retribution and vengeance, using her original colours to strike covertly at isolated traitor forces. Commanded by Bion Henricos of the Iron Hands, the ship is also home to many disgraced White Scars who have taken death-oaths to seek atonement. But tensions run higher with each new engagement and, without a wider strategy to guide them, the crew will surely come to a sudden end.

The Pharos stands as a beacon of light in the darkness, a whisper of hope in the silent void, a bastion of defiance in the face of treachery. Without it there could be no Imperium Secundus - why, then, do the masters of Ultramar know so little about its operation, or the dangers it could present? Young Oberdeii and Tebecai, Scouts of the 199th Company, descend into the depths beneath Mount Pharos in search of the truth...though it may haunt them for all time.
