  Warhammer 40,000

  It is the 41st millennium. For more than a hundred centuries the Emperor has sat immobile on the Golden Throne of Earth. He is the master of mankind by the will of the gods, and master of a million worlds by the might of his inexhaustible armies. He is a rotting carcass writhing invisibly with power from the Dark Age of Technology. He is the Carrion Lord of the Imperium for whom a thousand souls are sacrificed every day, so that he may never truly die.

  Yet even in his deathless state, the Emperor continues his eternal vigilance. Mighty battlefleets cross the daemon-infested miasma of the warp, the only route between distant stars, their way lit by the Astronomican, the psychic manifestation of the Emperor’s will. Vast armies give battle in his name on uncounted worlds. Greatest amongst His soldiers are the Adeptus Astartes, the Space Marines, bio-engineered super-warriors. Their comrades in arms are legion: the Astra Militarum and countless planetary defence forces, the ever-vigilant Inquisition and the tech-priests of the Adeptus Mechanicus to name only a few. But for all their multitudes, they are barely enough to hold off the ever-present threat from aliens, heretics, mutants – and worse.

  To be a man in such times is to be one amongst untold billions. It is to live in the cruellest and most bloody regime imaginable. These are the tales of those times. Forget the power of technology and science, for so much has been forgotten, never to be re-learned. Forget the promise of progress and understanding, for in the grim dark future there is only war. There is no peace amongst the stars, only an eternity of carnage and slaughter, and the laughter of thirsting gods.

  Chapter One

  Thessala

  The void is impossible for the human mind to encompass.

  Within the galaxy mankind calls home there are three hundred billion stars. Around these revolve hundreds of billions of worlds, and the spaces between are crowded by a diversity of objects which defy enumeration. Mankind’s galaxy is but one of trillions of galaxies in a universe of unguessable size. The distances between even proximate astronomical bodies are inconceivable to creatures evolved to walk the warmer regions of single small world.

  This is why the void cannot be understood. Not by men, nor by their machines.

  The magi of Mars insist on their understanding, but their apprehension can only ever be an abstraction, dead numbers modelled by dead-flesh cogitators. No matter how brutally expanded their minds, men cannot comprehend the majesty of the void.

  And when one considers the warp, that nightmare realm skulking behind that of touch, sound and sight, well… any being who claims understanding of that is either deluded or insane, and is in both cases dangerous.

  Among the higher races there are those better equipped to grasp their own limitations. They understand that the cosmos is ultimately unknowable; they accept their lack of insight. By comparison, the creatures of Terra are so crude in thought that – in the opinion of these more enlightened civilisations – it is a wonder humanity can understand anything at all.

  Humans are beings of short reach. Give them voidships, change their shape by geneforge and augmetic, provide them with weapons of sufficient power to break a star, and the children of Old Earth are still but apes removed from the savannah. And just as an ape’s mind cannot hold an ocean, and the notion of a whole world is inexplicable to it, so a man’s mind cannot hold the void, and the layered infinities of the warp are beyond him entirely.

  The Imperium claims a million worlds as its own. It is an empire spread gossamer-thin across the run of stars, its worlds so far removed from one another that it requires the bloody effort of countless men and women to sustain. In the grand flow of history, the Imperium is the greatest galactic empire of its day. To the people who populate it, it is the most powerful ever to have existed.

  However, to the uncaring universe, it is nothing, the latest in a line of such realms that stretches back to the days of the first thinking beings, when the stars were young and the warp was calm, and horror had yet to uncoil its tendrils into the material realm.

  There are philosophers that argue war is man’s natural state, and to the inhabitants of this era of blood it is a proven hypothesis. War is everywhere. Peace is the dream of a silent Emperor, broken by His treacherous sons.

  Those sons continued to fight.

  Over the green gas giant of Thessala, two great battlefleets engaged. Titanic energies snapped and blinked in the eternal night of space.

  The total efforts of star systems went into the construction of these fleets. Neither was free of the taint of blood, not in their construction – for tens of thousands of lives had been expended in their making – nor in their usage
. The resources of planets had been poured entire into the forging of their frames, and the secrets of ancient sciences plundered to bring them to murderous life. Both had been responsible for the levelling of civilisations.

  The fleets differed in only two regards. First was in their appearance. One was a gaudy assault on the senses, the other a motley collection of sober liveries. The second and more fundamental difference was in their allegiance. The sober fleet fought for the continuation of humanity’s great stellar empire; the gaudy one was dedicated to its extinction.

  The battlefleets pursued each other in a slow dance that broke through Thessala’s rings, hundreds of vessels ploughing gaps through the dust that would take centuries to close. The voiceless lightning of their guns filled the skies of Thessala’s inhabited moons. The lives of millions below depended on the outcome of the battle, but the consequences would ripple much further.

  At the centre of this iron storm there was no calm, no eye in which respite might be found. Instead, there was a pair of leviathans: the Ultramarines battle-barge Gauntlet of Power and the Emperor’s Children battleship Pride of the Emperor. Two vessels, forged in a common cause but now implacable enemies, locked together in mortal combat only thirty kilometres apart – no distance at all in void war.

  Each was the flagship of a primarch, genetically engineered demigods crafted by the Emperor of Mankind. Aboard the Gauntlet of Power stood Roboute Guilliman, the foundling of Ultramar, the Avenging Son. The Pride of the Emperor was home to Fulgrim – the traitor, the fallen exemplar, the blighted phoenix. Once covered in his Emperor’s blessings, Fulgrim had followed the arch-traitor Horus and pledged his allegiance to ancient dark gods, becoming the herald of perversity.

  In fighting for their father, both primarchs were made fathers themselves, though not of princes or strong daughters; through the application of arcane science, they were the sires of two of the Space Marine Legions, mankind’s greatest warriors. The Space Marines were lords of the galaxy, designed to reunite the human race and shepherd it to a glorious future. Instead, they had failed and turned upon one another, and their war had nearly destroyed the Imperium.

  Such fury a battlefleet can unleash!

  It can cow a world without a shot. It can extinguish the life of a species. Battlefleets are the tools of tyrants, whomever they fight for. Whether their admirals espouse salvation or damnation matters not to the execution of their purpose. Death follows in their wake.

  To those participating, a void war seems a terrifying, roiling chaos of violence, but it is the pinnacle of mankind’s destructive ingenuity, a whirl of gigantic explosions where lives are snuffed out by the hundred. In such combat, a single man is nothing; he is but part of the machine of the ship he serves, as essential or otherwise as a steel cog or an indicator lumen. He can do nothing but work his appointed task and pray his life will not end, or if it must end, that it does so in painless disintegration. A single crewman’s task dominates everything, even his fear of death. There is no escape from service. War and his part in it are the totality of his existence.

  Yet what is a void war to the timeless deeps of the blackness that envelops all these footling motes of light that sentient creatures battle so earnestly over? A void war is twinkles in the distance. It is silence. It is infinitesimals of matter sparking and dying, scintillas of metal and flesh consumed by transient fires. The detonation of a battleship kilometres long is insignificant to a cosmos where the death of a sun atomises worlds. On a galactic scale, the loss of a warship and ten thousand lives is a nugatory flash outshone by the billion-year candles of the stars.

  The inverse is true to a single man. His life is all that matters, for one life is all a man has, and he fears to lose it. Yet he must blindly serve in terror. The universe gives meagre gifts, and it does not care how they are spent.

  Over Thessala, mankind fought in a civil war already centuries old. The Emperor of Mankind, a human with the power of a god, had tried and failed to unite humanity’s scattered worlds so that the species might survive the supernatural threat of Chaos. His sons, the primarchs, godlike beings He had created to complete this task, had themselves been corrupted, and half had turned against Him. The Horus Heresy, that war was called. It had ended the Emperor’s dream.

  The Heresy was part of a war that had continued for aeons and would continue for aeons still.

  To the beings of this galaxy, the war was everything; to the blank gaze of time, it was nothing. And yet, for all humanity’s seeming inconsequence, the children of its greatest son held the fates of two realities in their careless grasp.

  Roboute Guilliman remained loyal to Terra. His ship was sternly decorated in gold, so much so that it rivalled that of Fulgrim’s vessel in ornamentation, but whereas the Gauntlet of Power was ornate, the Pride of the Emperor appeared vulgar. Its decoration had been applied with abandon – everything that could be adorned had been adorned. Back when the two ships had fought side by side, its extravagance had not been to the taste of the Ultramarines, who were born of more solemn worlds. Now it was an affront to decency, added to and added to again until tawdry obscured all trace of art. Neglect went hand in hand with this ostentation, and it made the Pride of the Emperor appear ugly. It was a decayed relic from a bygone age, like a theatre from a decadent century left to rot in the rain.

  However, the Pride of the Emperor’s ability to mete out destruction remained undiminished. At point-blank range, it traded punishing blows with the Gauntlet of Power as the ships passed slowly alongside each other. Huge cannons flared, exchanging projectiles the size of transit containers. The space between became a deadly thicket of lance beams and laser light. Void shields blurred and sparked with the dissipation of mighty energies. Multi-hued lightning silenced communications and burst sub-systems with their feedback for thousands of miles around. Weaponry capable of levelling cities blinked and flashed on both sides.

  Around these metal behemoths, dozens of other ships struggled in cosmic silence, some approaching the size and power of the flagships in their own right. Without exception, those on Fulgrim’s side were the damned ships of the Emperor’s Children. Though Fulgrim had lost his war and his humanity, his Legion yet held some cohesion. On Guilliman’s side fought half a dozen successor Chapters of the proud XIII Legion: the Ultramarines. Dissolution had been the price of faithfulness for the Legion of Ultramar, and though there were strengths in the smaller formations Guilliman had forced upon the Space Marines after the Great Heresy War, there were weaknesses also.

  For all their primarch’s famed strategical genius, the loyalists had been out-manoeuvred and caught. Their pursuit of the fallen primarch had become a fight for survival. Three fleet elements of Emperor’s Children had pinned the loyalists into place above Thessala; Fulgrim had turned his flight from Xolco into a devastating trap.

  Once, Roboute Guilliman would not have made such an error. Perhaps the dire situation over the emerald skies of Thessala was simple misfortune, and Fulgrim was no ordinary opponent, after all. Should Guilliman fail, history would surely be forgiving, if there were any good men left to write it.

  Or perhaps the truth was that rage had clouded the Avenging Son’s judgement. Perhaps, some dared whisper, Roboute Guilliman had allowed his desire for revenge to overtake his reason.

  Roboute Guilliman was stretched. Although several other primarchs still stood as champions of humanity, the wounded Imperium looked to Guilliman to save it. Every man has a limit, demigod or peasant, and Guilliman’s burden was the heaviest of all. He was the saviour of humanity.

  The Pride of the Emperor heeled over, bringing its portside weapons batteries into better firing arcs. In response, the Gauntlet of Power intensified its barrage, and the void shield covering the Pride of the Emperor’s ventral towers winked out.

  Explosions bloomed suddenly across hull plating encrusted with gold and filth.

  An opening had been made.

&
nbsp; On board the Gauntlet of Power, one hundred of Ultramar’s finest warriors waited on teleport blocks surrounded by buzzing machinery. They comprised fifty of the First Company and fifty of the Second, all garbed in the deep blue of the Ultramarines Chapter. The white helmets of the First Company’s veteran Space Marines, recessed under the cowls of Terminator armour, looked out at hundreds of tech-adepts and mortal crewmen labouring to prepare the Ultramarines’ way through the warp.

  The Space Marines of the Second Company were in standard power armour, and were being equipped with tall breaching shields by arming servitors. Their battleplate lacked the sheer thickness of Terminator armour, and the shields, though bulky, would increase their survivability in the close-quarter fighting of the coming boarding.

  Ammunition trains rumbled across the deck on plasteel wheels. Smartly uniformed Ultramarines Chapter menials handed out munitions to their masters while the enhanced warriors performed last-minute armour checks on themselves and their brothers. Chaplains strode from platform to platform, hearing oaths and affixing papers to armour with wax that hissed as they were impressed with sacred iron seals. Whether human or transhuman, every member of the Chapter worked with perfect efficiency. Even so, as invested as they were in their preparations, all of them had half an eye on the grand archway leading onto the deck.

  The ship shook violently. Alarms blared. Lumens spat sparks and went dark. A section of gantry clanged down from the tangle of struts and pipes that clogged the ceiling high above. The crew continued upon its business with unhurried purpose. Orders were given to reroute power. Emergency teams of armoured voidsmen and specialised servitors began clearing the wreckage. All was restored to order.

  Such calm made it easy to forget the punishing fire the ship was under. But there was no doubt that they were losing.

  This was not how the battle was supposed to have gone.

  From voxmitters studded into the columns and walls, a clipped voice sounded.

  ‘Shields down on the Pride of the Emperor. Prepare for assault.’ The words were swallowed by the clatter of preparation and tumult of war beating at the ship. They were not repeated, for the superior hearing of the Space Marines caught them all.
