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....

After the destruction of Monarchia and the Emperor's reprimanding of the Word Bearers Legion, the primarch Lorgar spent many long years searching the stars for the universal truths of the cosmos - when he finally came to gaze deep into the Eye of Terror, with grim inevitability he found that the Eye stared back.

As the epic battle for Terra rages and the future of mankind hangs in the balance, former Knight Errant Nathaniel Garro fights among the ashes and fire of the embattled Imperial Palace as the shadow of Horus Lupercal's triumph looms. From the brutal betrayal at Isstvan to the desperate flight of the Eisenstein, through his missions as Malcador the Sigillite's Agentia Primus, Garro's path has drawn him inexorably towards a destiny that can only end in bloodshed.

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.

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?

The Mor Deythan stand apart from their brothers of the Raven Guard Legion - indeed, there are many who would claim that they do not even exist. Blessed with the same powers of stealth and subterfuge as their primarch Corax, the self-styled Shadowmasters may slip through any battlefield, unseen and unheard, until they are ready to strike. Now, as the Legion mounts its attack on the forge-temples of Atlas, Brother-Sergeant Chamell leads his warriors on a vital, clandestine mission to strike at the enemy's heart.

Becalmed in the backwater Phall system, the Imperial Fists' relief fleet originally headed for Isstvan III has been waiting out the warp storms that waylaid them so many months ago. Under the assumed command of Captain Alexis Polux and seemingly forgotten by the rest of the Imperium, they hope yet to complete their mission and report back to their primarch Rogal Dorn, so that they might return to the greater conflict.

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....

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.

After bringing warning of Horus' treachery to Terra, Nathaniel Garro bade a solemn farewell to his Death Guard brethren and was set upon a more noble path than he ever could have imagined for himself. Now, an old comrade returns - Meric Voyen, once an Apothecary of the XIVth Legion, carrying a deadly cargo within the boundaries of the Solar System.

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.

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?

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.

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....

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.

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.

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.

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.

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.
