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....

In the immediate aftermath of the Word Bearers' attack on Calth, survivors from both sides were driven into the subterranean arcology shelters by the tortured Veridian star. While their primarch Roboute Guilliman had planned for many seemingly unthinkable eventualities, the Ultramarines now face a new war in the underworld - could Steloc Aethon, renowned captain of 'the Honoured 19th' Company, be the one to lead them to ultimate victory over the traitors?

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.

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.

In the depths of Calth's arcology network, the Underworld War has raged for years. Aeonid Thiel, previously an honoured sergeant of the Ultramarines, once again finds himself in trouble.

Renowned as one of the finest duellists the galaxy has ever known, Lucius seeks ever greater challenges against which to test himself. After the Emperor's Children Legion scattered in the wake of their primarch's apotheosis on Iydris, he finds his way into the domain of a similarly legendary swordsman - Sanakht of the Thousand Sons. But which of these infamous warriors carries the greater favour amongst their new masters?

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?

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.

The Black Ships are a mysterious and fearful sight - unmarked vessels that scour the distant reaches of the galaxy, ever watchful for latent psykers and witchbreeds for the monolithic Astra Telepathica. When one such ship, the Validus, is found drifting unpowered in the nightmare realm of the warp, it falls to the Sisters of Silence to uncover the reason behind it. As pariahs capable of blocking even the most potent psychic energy, Amendera Kendel and young Leilani Mollitas ready themselves for the worst....

In surviving the horrors onboard the Eisenstein, Nathaniel Garro proved his courage and absolute loyalty to the Emperor. On his return to Terra, Garro is despatched on a mission of even greater importance - a mission given to him by Malcador the Sigillite himself. He soon finds himself back amongst the stars and on the fields of battle, thrust into a warzone where the Ultramarines are purported to be battling a greenskin invasion. Once again Garro must fight for survival, but now he also fights to achieve a higher purpose....

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.

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.

Massacred, broken, their primarch lost, the Salamanders scour the killing fields for any sign of their liege - but they are being hunted, and carry their own dangers with them as well. Hear the aftermath of the Dropsite Massacre as the Salamanders search desperately for any sign of Vulkan.

In the strategium of the Vengeful Spirit, Warmaster Horus sets up his assault on his father's Imperium.

The Great Crusade is ending. The Emperor has returned to Terra, while Horus remains among the stars to complete the unification of humanity.

Granted a rare audience with the master of the Templars, the answer takes Voss on a revelatory journey to a time before Sigismund became a Space Marine.
