It is the thirty-second millennium and the Imperium is at peace. The Traitor Legions of Chaos are but a distant memory and the many alien races that have long plagued mankind are held in check by the Space Marines. But an ork invasion of unparalleled scale throws the Imperium into disarray. As worlds burn and renowned Space Marine Chapters are destroyed, can the Imperium pull together to defeat the Beast?

After the Great Crusade united the disparate worlds of humanity, the very warriors who made it possible turned on each other and tore it apart. This war was not only fought on a galactic scale – it was contested a million times over in brutal battles between former brothers and allies. Since the near-destruction of the Iron Hands, Raven Guard, and Salamanders on Isstvan V, scattered warbands from these 'Shattered Legions' have waged a guerrilla war on Horus' forces across the galaxy.

Captain Sicarius awakens on Macragge after his defeat on Damnos, but all is not well in the Ultramarines fortress-monastery.

Strange things stir in the darkness, and something deadly waits in the shadows for its chance to strike....

The Horus Heresy is a civil war on a scale the likes of which the galaxy has never seen before. After the Great Crusade united the disparate worlds of humanity, the very warriors who made it possible turned on each other and tore it apart. The Siege of Terra looms, and the fate of the galaxy balances on a razor's edge.

The Horus Heresy is a civil war on a scale the likes of which the galaxy has never seen before. After the Great Crusade united the disparate worlds of humanity, the very warriors who made it possible turned on each other and tore it apart. Soon after word reached Terra of Horus's nascent rebellion, Mars fell. Set upon by the forces of the Alpha Legion before they had even recovered from the Razing of Prospero, the Space Wolves have been hounded to the edge of the Alaxxes Nebula. In desperation, Leman Russ called out to his primarch brothers for aid. None came.

On the grim death world of Fenris, the Space Wolves Chapter selects its aspirants from the best and brightest of the young tribesmen. Ragnar of the Thunderfist tribe finds his life changed forever when he is chosen. After being revived from a savage death on the battlefield, Ragnar is recruited into the fearsome Space Wolves Chapter. He is then thrown into a galactic war against the dark forces of Chaos. However, the implanting of the Canis Helix unleashes his primal instincts and Ragnar must fight to control the beast within him.

After seven long years of conflict, the Horus Heresy nears its end. But now, as the Warmaster Horus marches on Terra to rip his father from the Throne, the seat of the arch-traitor’s power lies empty. Cthonia, a world once dominated by brutal murder-gangs, is occupied by the Emperor’s praetorians—the indomitable Imperial Fists. For the Sons of Horus, this outrage demands a reckoning.

Under almost constant besiegement by the hosts pouring from the Eye of Terror, Cadia acts as a bulwark against tyranny and death. Its fortresses and armies have held back the hordes of Chaos for centuries, but that grim defiance is about to reach its end. As Abaddon's Thirteenth Black Crusade batters Cadia's defences, and armies of the Imperium flock to reinforce this crucial world, a terrible ritual long in the making comes to fruition and the delicate balance of this brutal war shifts.

The Honoured joins the survivors from both sides in the immediate aftermath of the attack on Calth as they are 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. The Unburdened follows Kurtha Sedd of the Third Hand Chapter of the Word Bearers. Garro: Vow of Faith tells the continuing story of Nathaniel Garro.

Nearly a quarter of a million loyal Space Marines lost their lives on Isstvan V. The Dropsite Massacre lasted only a few hours, and yet the Iron Hands, Raven Guard, and Salamanders were slaughtered by those they had once called kin. Corax: Soulforge follows the defiant Raven Guard in the wake of Corax's failed plans to rebuild his Legion after the Dropsite Massacre.

When Horus fell, his Sons fell with him. A broken Legion, beset by rivalries and hunted by their erstwhile allies, the former Luna Wolves have scattered across the tortured realm of the Eye of Terror. And of Abaddon, greatest of the Warmaster's followers, nothing has been heard for many years. Until now....

After seven years of bitter war, the end has come at last for the conflict known infamously as the Horus Heresy. Terra now lies within the Warmaster’s sights, the Throneworld and the seat of his father’s rule. Horus’ desire is nothing less than the death of the Emperor of Mankind and the utter subjugation of the Imperium. He has become the ascendant vessel of Chaos and amassed a terrible army with which to enact his will and vengeance. But the way to the Throne will be hard as the primarch Rogal Dorn, the Praetorian and protector of Terra, marshals the defences.

There are those in the great expanse of the galaxy that seek profit wherever it is to be found: the deal makers, the opportunists and explorers – the Rogue Traders. Granted power by an ancient charter, sanctioned by the Emperor Himself, these scoundrels, entrepreneurs and adventurers roam the galaxy in search of fortune and glory. None perhaps are as hungry for these twin vices as Janus Draik.

A great darkness has befallen the galaxy, and the armies of Chaos are rampant. To survive, humanity must retaliate and take back what they have lost. By the will of the reborn primarch, Roboute Guilliman, is the Indomitus Crusade launched - a military undertaking that eclipses all others in known history. From the Throneworld of Terra does the Avenging Son hurl his fleets, their mission the very salvation of mankind.
