The Horus Heresy

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.

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....

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.

A shuttle returns to the Solar System bearing the sole survivor of a traitor attack - however, delirious and so close to death, his tale remains untold. Ison of the Knights Errant, formerly a Librarian of his Legion, delves into the mind of the warrior, and the truth of it will chill him to the core....

After the decimation of his Legion on the killing fields of Isstvan V, the primarch Corax sanctioned an accelerated implantation process to create new Raven Guard - a process subverted in secret by his enemies. But in spite of their horrendous mutations, the warriors of the Raptors still stand ready to do their primarch's bidding. When a watch-pack of Space Wolves legionaries arrives unannounced, it falls to Lieutenant Navar Hef to greet their warlike kinsmen and decide whether or not they might be hiding flaws of their own....

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.

The Dark Angels and the Night Lords fought one another to a bloody stalemate during the Thramas Crusade and, though the Lion eventually claimed victory, it left both Legions scattered and under-strength. Jago Sevatarion, First Captain of the Night Lords, languishes in a gaol cell in the heart of Ultramar. Far from a spent force, the Night Lords must consider where their loyalties lie, and what path they will take in the days and months to come.

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?

Aboard the Molech's Enlightenment, amongst the countless civilian refugees that fled the Warmaster's invasion, a serpent makes its nest. The Chaos cult that brought House Devine to its knees lives on, preying upon the weak and the helpless, and it falls to Alivia Sureka to root out the evil that hides in plain sight. Luckily for her, she has an ally who is more than familiar with such tactics the lone wolf Knight Errant, Severian.

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....

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.

Terra stands upon the brink of Unity. The armies of the self-proclaimed Emperor of Mankind have waged their bloody wars to bring the whole planet under his rule, crushing all traces of outlawed religion and worship from the face of this now secular utopia. But even the mighty Thunder Warriors cannot cow Uriah Olathaire, last priest of the Church of the Lightning Stone, as he goes about his empty, hollow rituals - and only one last and thoroughly unexpected visitor can bring any hope of a possible reconciliation.

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.

As the renegade forces of the Warmaster storm across the galaxy, a very different kind of war rages in the shadows of the Imperium - the Knights Errant, chosen of Malcador himself, move quietly in the dark places where others cannot. Battle-captain Nathaniel Garro makes his way to the Imperial Fists' mighty starfort Phalanx, seeking out another kindred soul for his elite band of warriors.

The Shadow Crusade spreads across Ultramar, with the Word Bearers 34th Company falling upon the isolated world of Percepton Primus. As the fighting draws out into a programme of extermination, embittered commander Sor Talgron begins to question his part in Lorgar's grander scheme - for one who stood beside primarchs and high lords in the grand halls of the Imperial Palace, what glory can there now be in punishing Guilliman's upstart sons?

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 Thramas Crusade draws to its inevitable conclusion, with the forces of the Dark Angels and the Night Lords locked in a struggle which neither side can abandon. The Night Haunter lies comatose after being mauled by his primarch brother Lion El'Jonson, and in his absence it falls to Sevatar and the remaining members of the Kyroptera to command the Legion. But the self-styled 'Prince of Crows' has his own plans to save the Night Lords from annihilation - plans he intends to follow, with or without his comrades in tow.

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 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.

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.
