The Horus Heresy

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.

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?

Before the Warmaster's betrayal, the primarchs and their Legions were a warrior brotherhood without equal. At Calth, a planetary jewel in Ultramar's crown, a great mustering is taking place. Two proud Legions gather in hopes of healing the discord after the notorious shaming of the Word Bearers at Monarchia. Captain Alcaeus of the Ultramarines plans on joining the muster but will not rest until the remnants of the Ghaslakh Empire are purged utterly from the galaxy, For honour and glory, he has sworn an oath to succeed.

Nathaniel Garro - loyalist Death Guard, and hero of the Eisenstein - has found a new calling in his service to the Emperor. Surrounded by a cloak of secrecy, Garro travels the galaxy in pursuit of his new goal. His quest will lead him to heart of the most destructive warzones and reveal a secret that will change the course of the Horus Heresy itself....

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 the war to save Ultramar from the traitor hosts of Horus ended, formerly disgraced Ultramarines Sergeant Aenoid Thiel believes that enemies still linger within the borders of the empire. Finding other men of purpose, fellow Space Marines known as the ‘Red-Marked’, Thiel wages a guerrilla war to root out these enemies and vanquish them for good. Following the threads of a previous mission, the Red-Marked arrive on the moon of Bael. There they find an underwater rigging station that has seemingly been abandoned.

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....

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.

The ravaged world of Tallarn plays host to the greatest armoured conflict in the history of mankind. The bitter and vengeful Iron Warriors led entire divisions of tanks and war machines across the befouled plains, until a macro-transporter plunged to the surface and ended a million lives. Stranded upon an unnamed, toxic battlefield that resembles nothing more than a graveyard of Titans, Warsmith Koparnos has precious little time left - will he find salvation amidst the dead god-machines, or succumb to violent madness?

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.

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.

'The Dark King' by Graham McNeill. The acts of terror and warmongering by Konrad Curze, Primarch of the Night Lords Legion, have earned the ire of his brother primarch, Rogal Dorn. Wracked by terrible visions of the future, Curze is driven insane and attacks Dorn, setting the Night Lord on an inexorable course towards eternal damnation. 'The Lightning Tower' by Dan Abnett. Rogal Dorn, Primarch of the Imperial Fists Legion, faces a stark reality - he must tear down the magnificence of the Emperor's Palace.

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.

As sanctioned executioners, the Wolves of Fenris were tasked with rooting out treachery at the heart of the Legions...but would they be capable of carrying out a death sentence upon one of the Emperor's own sons? Now, a stolen Alpha Legion dropship crashes on the primitive oceanic world of Pelago, bringing news of a terrible war that has erupted out among the stars. Will the pursuing traitors, thirsty for vengeance, reach the lone survivor before his own battle-brothers can?

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 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?

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 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?

Amon Tauromachian, one of the Emperor's elite Custodian Guard, returns to the Imperial Palace after a year on one of the Blood Games by which these exalted heroes train. Tasked with a new mission, he is sent to the hives of Hy Brasil to check on the loyalty of a notorious troublemaker. With the galaxy at war and half the Imperium's armies in rebellion, any hint of heresy on the Throneworld must be stamped out.
