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. 

Attached to Crusade Fleet Quintus - dubbed the Cursed Fleet by many - the Ultramarines of the Ithraca’s Vengeance are drawn to a stricken world. With millions enslaved, a malign necron technology siphons the souls of the innocent and heralds the Silent Kingdom’s expansion. The Ultramarines face an impossible decision: mount a desperate last stand to destroy the Pariah Nexus, or break away and damn the entire sector to bring word of this ancient foe’s resurgence to the only being capable of halting it - the Lord Primarch Roboute Guilliman.  

The Shattered Legions crew of the Sisypheum, broken and at the end of their endurance, find themselves divided - torn between following their resurrected captain on a suicidal mission or obeying orders to return to Terra and rejoin their Legion brothers. Following a series of garbled messages intercepted by the Kryptos, the divided warriors descend to the shattered surface of Luna. Here, their bonds of loyalty, duty, and their devotion to one another will be tested as ancient horrors of the earliest days of gene-manipulation are unleashed, and a long-buried secret is revealed.

In the centuries since his return from Commorragh, Fabius Bile has distanced himself from the affairs of friend and foe, content only to oversee the cruel evolution of his New Men. But when his creations are threatened by the monstrous haemonculi of the Thirteen Scars, the Manflayer is forced to seek out new allies and old enemies alike in an effort to preserve all that he has built. Homo Novus must survive...even if Fabius Bile must die to ensure it.   

In the immense city of Varangantua, life is cheap, but mistakes are expensive. When Probator Agusto Zidarov of the city’s enforcers is charged with locating the missing scion of a wealthy family, he knows full well that the chances of finding him alive are slight. The people demanding answers, though, are powerful and ruthless, and he is soon immersed in a world of criminal cartels and corporate warfare where even an enforcer’s survival is far from guaranteed.

Constantin Valdor. It is a name that brings forth images of heroism, honour and peerless duty. For it is he who commands the will of the Legio Custodes that most esteemed and dedicated cadre of elite warriors. He is the Emperor’s sword, His shield, His banner and he knows no equal. Clad in shining auramite, his fist clenched around the haft of his Guardian Spear, he is the bulwark against all enemies of the throne, within or without. Nearing the end of the wars of Unity, Valdor’s courage and purpose is put to the test as never before. 

A single, harrowing trial stands between supplicant Ferendir and a life of loyal service to his Alarith temple. But on the day of the young aelf’s final initiation, a Slaaneshi warhost descends upon his mountain home, leaving slaughter and destruction in their wake and stealing a long-hidden Lumineth treasure of terrible power. His world now torn asunder, Ferendir and his stalwart masters, Serath and Desriel, are forced to navigate a realm at war to stop the depraved warriors of the Dark Prince. 

Ciaphas Cain's latest mission takes him and his Valhallan regiment to the planet of Adumbria to defend against an approaching Chaos invasion. However, infighting with fellow Imperial Guard regiments from the world of Tallarn, commanded by an old 'friend' of Cain's from the Schola Progenium and the uprising of a sinister cult on the planet puts paid to any hopes of an easy life.

Experience the beginning of an epic, time-twisting saga of revenge, betrayal and attempted atonement. John French takes the Ahriman you know and love from the Horus Heresy in new and interesting directions, making him both deeply sympathetic and thoroughly evil.   

As Guilliman, Regent of Terra, heads off to lead the Indomitus Crusade, he leaves behind a world still in turmoil, beset by cult activity. Stripped of its huge armies for the galactic offensive, recovery is precarious. The Custodians do what they can while keeping the Palace secure, and the Sisters of Silence rebuild their citadel on Luna. When the warship Phalanx returns, it seems that stability will at last be assured. However, as reconquest forces push out further into the slums, they come across signs that another mysterious foe is active.

As the Great Rift tears the galaxy apart, portents and darkness beset Mephiston. At the time when he needs his psychic sight the most, the chief librarian's powers are rendered blind. Haunted by the ghosts of the damned, their purpose unclear, Mephiston takes his ship the Blood Oath and the Blood Angels in his charge to the world of Morsus, where he believes the source of his psychic blindness is to be found. But Morsus is embroiled in conflict too, a longstanding struggle between the Imperium and some of its most ancient foes called the Revenant Crusade. 

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.

The hunters have become the hunted. The Night Lords flee to the dark fringes of the Imperium to escape their relentless pursuers - the aeldari of Craftworld Ulthwé. Their flight takes them to the carrion world of Tsagualsa, where their primarch died and their Legion was broken. There, history will repeat itself as a deadly assassin stalks the shadows, and the Night Lords are drawn into a battle they are destined to lose. 

The Custodian Guard have stood watch over the Emperor's Palace on Terra since the foundation of the Imperium. Charged with protecting the Master of Mankind from all threats, within and without, their fearsome resolve is renowned throughout the galaxy, and their golden armour is the last thing that a would-be assassin or saboteur will ever see.

The shrine world of Divinatus Prime has become lost to the light of the Astronomican, and no ship can piece its veil. Only the Lord of Death himself, Blood Angels Chief Librarian Mephiston, has any hope of discerning the fate of this once pious world. After enacting a powerful blood ritual, Mephiston and an honour guard of his fellow Blood Angels reach the stricken shrine world to find it seized by religious civil war. Each faction fights for dominance of a potent artefact, the Blade Petrific, said to be wrought by the Emperor Himself.
