The Horus Heresy

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.

The battle for Tallarn rages between the traitor Iron Warriors and the Imperial Army. A carpet of armour covers the surface of the toxic planet: Dreadnoughts versus tanks versus Titans. But what secret purpose drives the Iron Warriors onwards to war?

Oll Persson stands apart from the rest of mankind. He is one of the old ones, one of the undying. One of the Perpetuals. Now, fleeing from the ruins of Calth with his band of fellow refugees, the vagaries of the warp have brought him through the backways of time and space to a city that rests on the edge of oblivion...and no further. The path has ended abruptly, and Oll's enemies are finally closing in. Will his immortality be enough to save him this time?

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....

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....

Long considering themselves persecuted by the rest of the Imperium, the apostles of the XVIIth Legion have courted sedition, betrayal and even open heresy for decades. But for Kurtha Sedd of the Third Hand Chapter, the Word Bearers' assault on Calth has proven...troubling. Drawn into the haunted shadows of the planet's underworld, the Chaplain and his devout brethren must now put aside all other concerns and continue to wage war against the Ultramarines, no matter the ultimate cost.

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.

Since the near-destruction of the Iron Hands, Raven Guard and Salamanders on Isstvan V, scattered warbands from these 'shattered Legions' have waged a guerrilla war on Horus' forces across the galaxy. Now, the crew of the Sisypheum are drawn into a covert assault on a hidden Alpha Legion outpost - an assault orchestrated by none other than the infamous warleader Shadrak Meduson himself. But what does Meduson really hope to make from such a bold move against the sons of Alpharius, arguably the undisputed masters of deception?

The Space Wolves of the VIth Legion are among the most fierce and dedicated of the Legiones Astartes, bringing the Emperor's wrath against the many enemies of mankind. As part of the 954th Expedition, Wolf Lord Bulveye's warriors of the 13th Company come across a world previously shrouded by warp storms and cut off from the rest of the Imperium - when it becomes apparent that the human population is being raided by mysterious xenos known as 'the Harrowers', the Space Wolves are duty-bound to intervene.

In the aftermath of the Isstvan V massacre, a group of Salamanders survivors lay a trap for their foes, a group of unwary Night Lords on the hunt for easy prey. As they lure the Night Haunter's murderous sons into a trap, the battered survivors of the Dropsite Massacre contemplate their fate...and for some of them, it may come sooner than they think.

As daemons swarm across the fields of Velbayne, bringing madness and Chaos to all that they touch, Leman Russ and the Rout stand arrayed against them. Packs fight back to back, brothers protecting one another - except for one. The Lone Wolf, the warrior without a pack, stands alone. And somewhere on the battlefield is a foe against which he will have vengeance.

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.

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?
