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. 

On the 13th day of Secundus, the bombardment of Terra began. With the solar defences overcome through the devastating strength of the Traitor armada and the power of the warp, Horus launches his assault on the Throneworld in earnest. After withstanding a ferocious barrage of ordnance, an immense ground war commences outside the Palace, with every inch gained paid for in the lives of billions. 

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.

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.

On the world of Verghast, a grinding war between two hive cities - one loyal to the Imperium, the other fallen to the worship of the Dark Gods - is bolstered by the forces of the Astra Militarum, spearheaded by the Colonel-Commissar Gaunt and the Tanith First and Only. But bitter rivalries and treachery threaten to derail the defence of Vervunhive, and it falls to Gaunt to take command of the Imperial forces and forge victory from an almost certain defeat.   

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. 

Belisarius Cawl, Archmagos Dominus of the Adeptus Mechanicus, is the most brilliant mind alive. For 10,000 years he has furthered the cause of mankind, working under the aegis of the Emperor and Lord Commander Roboute Guilliman to prevent the inexorable march of the alien and the traitor. Many call him heretic, but all must recognise the magnitude of his achievements, for who else but he was entrusted to create a new generation of Space Marines?  

The Night Lords were once among the most potent forces of the Imperium, Space Marines who used fear itself as their weapon. Now, cast adrift from the Emperor's light and hunted as heretics after their monstrous betrayal, the Night Lords clad themselves in symbols of death and fight the Long War, bringing pain and terror to all who worship the corpse-god of Terra. A summons from Warmaster Abaddon sends these rebels on a dangerous journey that leads inexorably to a conflict with the Emperor's chosen warriors, the Blood Angels.  

Uncompromising and fierce, Commissar Severina Raine has always served the Imperium with the utmost distinction. Attached to the 11th Antari Rifles, she instills order and courage in the face of utter horror. The Chaos cult, the Sighted, have swept throughout the Bale Stars and a shadow has fallen across its benighted worlds. A great campaign led by the vaunted hero Lord-General Militant Alar Serek is underway to free the system from tyranny and enslavement, but the price of victory must be paid in blood.

Driven on by their hatred of the False Emperor, the Night Lords stalk the shadows of the galaxy, eternally seeking revenge for the death of their primarch. Their dark quest leads them to a fractious alliance with the Red Corsairs, united only by a common enemy. Together with this piratical band of renegades, they bring their ways of destruction to the fortress-monastery of the Marines Errant.

For a thousand years, the Sabbat Worlds have been lost to the Imperium, claimed by the dread powers of Chaos. Now, a mighty crusade seeks to return the sector to Imperial rule. And at the forefront of that crusade are Colonel-Commissar Ibram Gaunt and the Tanith First and Only - better known as Gaunt’s Ghosts. Trapped in the grinding trench warfare of Fortis Binary, the Ghosts find themselves drawn into a conspiracy to assassinate the crusade’s leader, Warmaster Macaroth.

Gotrek and Felix: unsung heroes of the Empire or nothing more than common thieves and murderers? The truth perhaps lies somewhere in between and depends entirely upon whom you ask. Seeking to undermine the very fabric of the Empire with their arcane warp-sorcery, the skaven, twisted Chaos rat-men, are at large in the reeking sewers beneath the city. Led by Grey Seer Thanquol, the servants of the Horned Rat are determined to overthrow this bastion of humanity. Against such forces, what possible threat can just two hard-bitten adventurers pose? 

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.

On Monthax, Colonel-Commissar Ibram Gaunt and his Tanith First-and-Only await the order to advance into the sweltering jungle and drive the alien eldar from the world. As battle approaches, Gaunt walks the lines, raising his men's spirits and remembering their most heroic deeds - and the tragedies that have dogged Gaunt's Ghosts from the day of their founding on lost Tanith. The day that Gaunt became known as the Ghostmaker. 

Horus’ armada gathers, and he has defeated all enemies sent against him, even the Emperor’s own executioner. One barrier remains before he can strike for Terra and lay waste to the Emperor’s dream. The Beta-Garmon system occupies the most direct and only viable route to the Solar System and Terra. To break it, Horus assembles a war host of incredible proportions and Titans in untold numbers. To lose here is to lose the war, and Horus has no intention of turning back. But the Imperium understands the importance of Beta-Garmon too.
