The Horus Heresy

Crowned as the new Emperor of Imperium Secundus, Sanguinius of the Blood Angels faces the very real threat of betrayal from within his new realm. As ever, it falls to his Sanguinary Guard to protect the primarch, and Commander Azkaellon must resort to the most dire of measures....

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?

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?

On a distant world of the Imperium, an agent of Rogal Dorn finds himself the prisoner of a Legion whose loyalties may be divided. Shackled and bound, the former Luna Wolf must fight a battle of wits with his captor, lest the course of the Horus Heresy take an unexpected turn. Will his very presence drive his erstwhile allies into the arms of the Warmaster, or will maintaining the status quo prevent another Legion from turning traitor? And just who is the mysterious Space Marine aiding him from the shadows?

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?

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....

On the doorstep of Holy Terra, the shadow of treachery still lurks. Upon a comet-shrine dedicated to the glory of Unity, a group of heretic Word Bearers prepare to return to the Solar System after being abandoned by their brethren - only the forces commanded by Sigismund, First Captain of the Imperial Fists, stand between the traitors and their goal. But will the legendary Templar's skill at arms be enough to prevail over this new enemy, or will the doubt in his heart prove ultimately to be his undoing?

While the war rages on across the galaxy, for many on the Throneworld of Terra it exists only in hearsay. But in the course of her daily duties, humble adept Katanoh Tallery discovers evidence of a conspiracy within the monolithic Administratum - surely, this can only be the precursor to a traitor attack on the Solar System itself? Fleeing into the shadows, she soon finds herself at the mercy of the mysterious Knight Errant Nathaniel Garro. Will this stalwart defender of mankind be her saviour, or her executioner?

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?

Since he was crippled by rebel treachery on Sixty-Three Nineteen, Maloghurst the Twisted has continued to serve Warmaster Horus as his closest aide and confidant. His loyalty has remained constant, but the XVI Legion has changed. Rivalry and personal ambition run rife, and although Horus' authority is supreme, his equerry's is certainly not. When a daemonic plot to infest the Vengeful Spirit comes to light, Maloghurst reluctantly turns to the few allies he has left: the mysterious Davinites.

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.

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.

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....

The ravaged world of Tallarn now plays host to the greatest armoured conflict in the history of mankind, with the bitter and vengeful Iron Warriors leading warhosts of tanks and Titans across the befouled plains. In desperation, a covert team of Imperial Fists resort to seemingly unthinkable measures in order to regain the upper hand - but will their mission to seize the macro-transporter Eagle's Talon ensure victory or merely spell doom for their loyal allies on the surface below?

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.

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.

After returning from Calth and the Underworld War, Sergeant Aeonid Thiel is summoned before his primarch Roboute Guilliman. The fragile peace of Imperium Secundus is threatened by traitor warbands left behind by the Shadow Crusade, and a new order of battle must be written.

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.

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....

The primarch Angron: gladiator-king and Horus' lunatic attack dog. Never having hidden his resentment for his brothers, he now carves a bloody swathe through the galaxy in the Warmaster's name, with the Heresy providing a convenient excuse to indulge his love of brutal warfare. When they are tasked with a secretive mission alongside the Word Bearers Legion, the World Eaters' violent tendencies soon attract the attention of xenos raiders, troubled by the portents surrounding the primarch's berserk fury.
