The Horus Heresy

As one of the vaunted Crusader Host, Brother Crius stood as the representative of the X Legion upon the soil of Holy Terra, but when he learns of the death of his beloved primarch Ferrus Manus at the hands of the traitors, his stoic, mechanical grief imbues him with the strength and resolve to undertake a special mission on behalf of Rogal Dorn himself. Striking out into the stars, he searches for any signs of his lost Iron Hands brethren, hoping to bring them back to Terra to aid in the final defence of the Palace.

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?

Chagrined by his defeat at the hands of Jaghatai Khan, Mortarion abandons the pursuit of the White Scars and instead leads the Death Guard in a spiteful, punitive rampage across the systems of the Prosperine empire. World after world has fallen to this horrific onslaught, and yet the insular and secretive primarch seems preoccupied by some other unspoken goal. Finally, on Terathalion, the truth of Mortarion's sinister heritage will be exposed, and the future of the XIV Legion will be written....

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.

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....

Captain Tybalt Marr of the Sons of Horus, so often overlooked by his more glory-hungry brethren, returns to his Legion in triumph. However, his boasts of having slain the infamous Iron Hands warleader Shadrak Meduson soon fall flat when he learns of the recent assassination attempt on Horus himself. Gathering his forces upon the conquered world of Dwell, Marr returns to battle against the Shattered Legions, determined to earn his rightful place in history.

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....

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.

It is the 31st millennium. Under the benevolent leadership of the Immortal Emperor, the Imperium of Man hasstretched out across the galaxy. It is a golden age of discovery and conquest. But now, on the eve of victory, the Emperor leaves the front lines, entrusting the great crusade to his favourite son, Horus. Promoted to Warmaster, can the idealistic Horus carry out the Emperor's grand plan, or will this promotion sow the seeds of heresy amongst his brothers?

The Great Crusade that has taken humanity into the stars continues. The Emperor of Mankind has handed the reins of command to his favoured son, the Warmaster Horus. Yet all is not well in the armies of the Imperium. Horus is still battling against the jealousy and resentment of his brother primarchs, and when he is injured in combat on the planet Davin, he must also battle his inner daemon. With all the temptations that Chaos has to offer, can the weakened Horus resist?

Having recovered from his grievous injuries, Warmaster Horus leads the triumphant Imperial forces against the rebel world of Isstvan III. Though the rebels are swiftly crushed, Horus' treachery is finally revealed when the planet is razed by virus bombs and Space Marines turn on their battle brothers in the most bitter struggle imaginable.

Having witnessed the terrible massacre of Imperial forces on Isstvan III, Death Guard Captain Garro seizes a ship and sets a course for Terra to warn the Emperor of Horus' treachery. But when the fleeing Eisenstein is damaged by enemy fire, it becomes stranded in the warp - the realm of the Dark Powers. Can Garro and his men survive the depredations of Chaos and get his warning to the Emperor before Horus' plans reach fruition?

Under the command of the newly appointed Warmaster Horus, the Great Crusade continues. Fulgrim, Primarch of the Emperor's Children, leads his warriors into battle against a vile alien foe, unaware of the darker forces that have already set their sights upon the Imperium of Man. Loyalties are tested and every murderous whim indulged as the Emperor's Children take their first steps down the road to true corruption - a road that will ultimately lead them to the killing fields of Isstvan V....

The planet of Caliban exists much as it has for thousands of years - the knightly orders protect the common people, fighting back the beasts that lurk in the depths of the seemingly endless forests. Young Zahariel and Nemiel aspire to join the greatest of the orders, led by the example of mighty Lion El'Jonson and his vision of a peaceful and unified world. But the coming of the Imperium brings new concerns and a new destiny for the Lion as part of the Great Crusade, and the sons of Caliban must decide if they will follow him to glory among the stars.

A Great War is coming, and it will engulf the Imperium of Man. The Space Marines of the Alpha Legion, the last and most secretive of all the Astartes brotherhoods, arrive on a heathen world to support the Imperial Army in a pacification campaign against strange and uncanny forces. But what drives the Alpha Legion?

Now that news of Horus' treachery is in the open, a time of testing has come. Some Legions have already declared their allegiance to the Warmaster while the loyalty of others lies firmly with the Emperor. As Horus deploys his forces, loyalist Astartes learn that a massive Wordbearers fleet is heading to Ultramar, home of the Ultramarines. Unless they can intercept the fleet, and destroy the mighty battleship that has been sent to reinforce it, the Ultramarines may suffer a blow from which they will never recover.

As the flames of treachery spread throughout the Imperium, Horus plots to subvert or destroy all those who would stand against him. On Mars, home world of the Mechanicum priesthood, the great manufactory-cities have long produced much of the weaponry required for the expeditionary fleets across the galaxy - making the world invaluable to whoever controls it in the coming war.

When Horus the Warmaster rebelled against the Emperor, the ensuing civil war nearly destroyed the Imperium. War raged across galaxy, pitting Astartes against their battle-brothers in a struggle where death was the only victor. But long before that, the Legions struggled with their identities and the demands of the Great Crusade. From battles with alien invaders to conflicts within a Legion, and even dealing with a wayward primarch, these stories show the battles fought as the Great Crusade draws to a close and the Horus Heresy begins....

With news of Horus' treachery spreading across the galaxy, the Great Crusade grinds to a halt as the primarchs and their Legions decide where their loyalty lies - with the Emperor or with the rebel Warmaster. The Dark Angels, too, face a time of testing, both among the stars and on their home world, Caliban. Luther, once Lion El'Jonson's trusted second-in-command, now languishes as an exile in all but name while his master struggles to thwart the traitors' advance upon the forge world Diamat.

Censured at the Council of Nikaea for his flagrant use of sorcery, Magnus the Red and his Thousand Sons Legion retreat to their homeworld of Prospero to continue their use of the arcane arts in secret. But when the ill-fated primarch forsees the treachery of Warmaster Horus and warns the Emperor with the very powers he was forbidden to use, the Master of Mankind dispatches fellow primarch Leman Russ to attack Prospero itself.
