The Horus Heresy

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.

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.

In the strategium of the Vengeful Spirit, Warmaster Horus sets up his assault on his father's Imperium. He discusses his brothers, loyal and traitor, and his hopes and fears for the war he has begun...and whether or not he really thinks it can end it. But just who is Horus talking to as he lays out his plans for galactic domination?

The galaxy is divided, but while his armies prepare for battle, the Emperor himself remains curiously absent. In his place stands Malcador - legendary Sigillite, First Lord of Terra and regent to the throne - now arguably the single most powerful man in the Imperium. Army officer Khalid Hassan reports back to the Palace after a disastrous secret mission into the wastelands of Gyptus but soon learns an awful truth about the destiny of mankind. Where do Malcador's true loyalties lie?

In surviving the horrors onboard the Eisenstein, Nathaniel Garro proved his courage and absolute loyalty to the Emperor. On his return to Terra, Garro is despatched on a mission of even greater importance - a mission given to him by Malcador the Sigillite himself. He soon finds himself back amongst the stars and on the fields of battle, thrust into a warzone where the Ultramarines are purported to be battling a greenskin invasion. Once again Garro must fight for survival, but now he also fights to achieve a higher purpose....

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.

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.

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....

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?

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?

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?

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....

As one of the many staging grounds for the forces serving in the Great Crusade, the verdant world of Tallarn has long served as a transfer point for the personnel and war machines of the Imperial Army. Now, destroyed by a deadly virus-bomb attack launched by the battered Iron Warriors fleet, the entire world is reduced to a toxic wasteland where the survivors must fight to defend what little remains of their home.

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?

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 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.

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....

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?

As Calth burns, the Battle Titans of the Fire Masters legion take to the streets of the city of Ithraca, ready to massacre the fleeing civilian population in the name of their new, dark masters. But the remaining loyalist engines of the Legio Praesagius - the True Messengers - still stand ready to defend the Imperium, even in the face of almost certain death. With the nearby Ultramarines forces scattered and lost, the people of Ithraca must fend for themselves as gigantic war machines unleash apocalyptic weaponry across the ravaged skyline....

Coaxed and goaded by the wiles of the warp – and an entity whose whispered truths stretch even his credulity – Eidolon finds himself stranded around the world of Tatricala, where the ghosts of his past haunt every fated step. Now he must choose which life he wants to lead… and how much of his soul he is willing to sacrifice for it. If Eidolon cannot banish his daemons, then they will surely take him for their own.
