While voyaging through the depths of the warp, the infamous blademaster Lucius the Eternal is challenged by a servant of another god - a champion of the old Death Guard Legion, no less. Keen to remain dominant over his preening and ambitious rivals in the Cohors Nasicae, Lucius takes up his sword without a second thought...but could an unfeeling daemonhost of Nurgle, or the voices inside his own head, be the undoing of his Slaaneshi curse?

In the fighting pits of the Conqueror, Khârn and his fellow World Eaters compete in ever-bloodier contests of carnage and mayhem. As the Butcher's Nails dig ever deeper into their brains, the Legion have forsaken the Crimson Path. Now they walk a darker, more dangerous road: the Eightfold Path.

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....

Lupercalia burns, the might of the Traitor Legions reducing the last redoubt of the Sons of Horus to rubble. And through the ruins strides Apothecary Fabius of the Emperor's Children, with an army of vile genetic experiments. But what does the twisted Apothecary want in the temple to the fallen primarch Horus? And will he find it?

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.

Caught by the renegade forces of the Alpha Legion and forced to take refuge in the Alaxxes Nebula, the Space Wolves are bloodied but unbowed. The young pack leader Bjorn - now known to his warriors as 'the One-Handed' - is desperate to recover his honour in battle, but replacing lost limbs for proud legionaries is not a task worthy of the Iron Priests. If Bjorn is to fight again, then he must seek out new claws for himself and christen them in the blood of the traitors....

On the world of Colchis, mighty religions rule a decaying society in the name of absent gods - until the arrival of Lorgar. Primarch, prophet, leader of destiny, the Golden One is raised by Kor Phaeron, priest of the Covenant, to be his weapon in a quest for power. As religious war spreads across the planet, spearheaded by the Brotherhood of Lorgar, the primarch is plagued by visions of the future and the coming of the Emperor.

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.

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....

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.

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.

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.

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.

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.
