The thought of losing control and becoming little more than a killer without a conscience frightened him greatly. Briefly he thought of confessing to the growing darkness within him, but bit back the words, unsure of how to articulate his feelings. Such weaknesses were foreign to a Space Marine and he had not the humanity to reach out and express them.

  The three Space Marines watched the boiling sky in the far distance with trepidation. None would ever forget the horrors they had witnessed on Ichar IV and the thought of facing such a foe again brought nothing but apprehension.

  While they knew they could fight any foe and triumph, they were but a hundred warriors and, against such a numberless horde, there was only so much they could do.

  The soldiers around them were numerous, though nowhere near as numerous as the tyranids. But where the defenders of Tarsis Ultra had the advantage over the alien horde was in their basic humanity, the courage that came from defending one’s hearth and home.

  The very thing Uriel and his sergeants lacked.

  THE WESTERN MOUNTAINS writhed with motion. Thousands upon thousands of mycetic spores hammered the ground, each disgorging a mucus-covered creature that hissed and screeched in animal hunger. Swarms of beasts gathered in the shadow of the twisting, smoke-wreathed forests, the natural beauty of the ecology perverted into monstrous, alien flora that consumed the nutrients in the soil and spread a dark stain of necrotic growth across the landscape. Bubbling pools of acids and enzymes formed in sunken patches of ground, small devourer organisms plunging into the acid baths to give up the energy they had consumed to feed the voracious appetite of the alien fleet.

  When enough creatures had gathered in a snapping, biting mass, the horde set off at some unseen signal, powerful hind limbs propelling the bounding swarm through the deep snow of the mountains and onto the plain below. Larger creatures stamped through the snow, their bestial jaws snapping and clawed hands sweeping aside the smaller aliens as they moved through the swarm. Tens of thousands of aliens charged down the mountains, directed to their prey by invisible cords of psychic hunger that connected them with thousands of flying gargoyles that swept ahead of the swarm and reeled them closer to their prey.

  All across Tarsis Ultra, the beasts of the tyranid invasion closed on their targets.

  GUARDSMAN PAVEL LEFORTO of the Erebus Defence Legion nervously licked his lips, then wished he hadn’t as he felt the cold freeze the moisture within seconds. He desperately needed to empty his full bladder, but the latrine pits were three hundred metres behind his platoon’s section of the forward trench. He cursed the need to drink so much water. At his age, his bladder wasn’t the strongest in the world, and the need to drink five canteens of water every day to stave off dehydration – a very real danger in this cold climate – was a constant pain.

  But the corpsmen of the Logres regiment were all humourless bastards when it came to cold weather injuries, and it was now a court martial offence to suffer from dehydration, frostbite or hypothermia.

  The trench was not as cold as it had been in the weeks previous to this, though high on the periscope platform, a cold

  wind chilled him to the marrow despite the many-layered thermal overwhites he wore. The presence of so many soldiers raised the temperature by several degrees and the tanks had become a magnet for cold soldiers who basked in the heat radiating from their engine blocks. This section of trench alone was home to over three hundred soldiers, a mix of squads from the Logres and Krieg regiments. None of the off-world soldiers were that friendly, and treated the majority of the Defence Legion soldiers like weekend warriors, amateurs playing in the big boys’ arena. This combined with fraying tempers caused by the miserable conditions, had made relations between the defenders of Tarsis Ultra strained to say the least. The initial excitement of leaving his regular post in the Erebus smelteries had long-since evaporated and he missed the predictable monotony of his work.

  But more than that, he missed returning home to his wife and children at the end of the day and the cramped, yet homely hab-unit that they and three other families shared high on the north face of District Secundus. Sonya would be readying the evening meal about now and his two children, Hollia and little Solan, would be on their way back from the scholum. The ache of their absence was painful and Pavel looked forward to an end to this war when he could be reunited with them.

  Banishing thoughts of home and family, he pressed his face to the rubberised eyecups of the bipod-mounted periscope magnoculars and pressed the button that flipped open the polarised lens covers. He shifted his balaclava under his helmet to get a good look through the magnoculars. The heat from his skin momentarily fogged the glass before the image resolved into clarity before him.

  The bleak, unbroken whiteness of the landscape was empty as far as he could see, though he knew that the freezing temperatures reduced his depth perception and visual acuity. Still, he wasn’t the only one watching this sector, so he wasn’t too bothered that he couldn’t see much. Seeing nothing was a good thing anyway, wasn’t it?

  ‘Anything?’ asked his squad mate, Vadim Kotash, holding out a steaming tin mug filled with caffeine towards Pavel. At forty-five years old, Vadim was a year younger than Pavel and together, they were probably the oldest men in the platoon.

  His friend’s face was obscured by his balaclava and snow-goggles, a scarf wrapped around his mouth muffling his words.

  ‘Nah,’ said Pavel, snapping the covers back over the magnoculars. He took the mug and, pulling the scarf from his mouth, sipped his hot drink. ‘Can’t see anything worth a damn in this weather.’

  ‘Aye, I hear that. Con tells me that Kellis got taken back to the medicae yesterday. Snow blindness got him. The young fool kept taking his goggles off.’

  The provosts will haul him over the coals for that.’

  ‘I wouldn’t mind being hauled over the coals, it might warm my old bones up,’ chuckled Vadim.

  ‘It would take the furnace back in the smeltery for that now,’ said Pavel.

  Vadim nodded as an officer in a long, mud-stained Krieg greatcoat and a thick, furred colback studded with a lieutenant’s pips stalked down the trench. He carried his lasgun slung over his shoulder and he scowled in displeasure as he marched.

  ‘Uh-oh, it’s Konarski,’ hissed Vadim, tapping Pavel’s shoulder, but it was already too late.

  “You!’ snapped Konarski. “Why the hell aren’t you watching for the enemy?’

  Pavel started at the sharp bark of Konarski’s voice, spilling caffeine onto his overwhites.

  ‘Uh, sorry, sir. I was just—’

  ‘I don’t give a damn what you were doing, you are supposed to be watching for the enemy. You might single-handedly condemn us all to death with your carelessness. I’ll have you on report for this, you mark my words.’

  Pavel groaned in frustration as Konarski fished out a battered, and obviously well-used, disciplinary infractions notebook and a worn-down nub of a pencil.

  ‘Right then, soldier, name, rank and serial numb—’

  Konarski never got a chance to finish his question as the alert sirens blared into life all along the front line. Wailing klaxons screamed a warning to the soldiers and the trenches erupted in panicked motion as troopers fumbled for their weapons and scrambled to the trench’s firing step. Pavel dropped his mug and pressed his face to the trench periscope, the altercation with Konarski forgotten.

  He snapped up the covers and gasped as he saw the swarming black shapes knifing through the air towards the trenches. The entire upper half of the viewer was filled with alien creatures and he could hear the rustling roar of thousands of beating wings as they drew nearer.

  Realising he no longer needed the scope, Pavel dropped to the firing step and lifted his rifle to his shoulder. Engines belched smoke as Hydra flak tanks drove forward, sending frozen mud and snow flying as their tracks churned the ground. Ammunition trucks followed the tanks, each carrying three thousand shells in easy-to-load ammo panniers, since a Hydr
a could pump out up to a thousand rounds a minute.

  Pavel watched the approaching cloud of flying aliens with a mixture of terror and anticipation. Never having journeyed far beyond the walls of Erebus, he was excited to have the chance to see real aliens from afar. But if even half of the information given in the platoon briefings on these creatures was true, then he knew that in all probability he wouldn’t enjoy too close an encounter with a tyranid organism.

  The noise of the sirens died, and the awful sound of the aliens’ flapping wings echoed from the valley sides along with a brittle, high-pitched noise of millions of claws clicking together.

  ‘Hold your fire until they get closer,’ ordered a captain of the Logres regiment, calmly walking behind them with his sword drawn, the blade resting on his shoulder. ‘Don’t waste any of your shots, you’ll need every one of them.’

  Pavel caught Vadim’s eye, seeing the fear behind his friend’s nervous smile.

  ‘Don’t worry, Vadim,’ said Pavel. ‘Just keep a fresh power cell handy and you’ll be fine.’

  Vadim nodded shakily as the Hydras began firing and the noise of the quad-barrelled weapons as they began pumping shells into the approaching swarm was deafening. Hundreds of explosions burst among the flying creatures, painting the sky with dirty smears, and the distant screeches of dying creatures drifted through the cold air. Steam billowed from the air-cooled barrels and robed enginseers circled each tank, sprinkling their hulls with blessed water from their aspergillum as the guns sprayed the air with explosive shells.

  Pavel watched the swarm above convulse as fire from the Hydras ripped through it, blasting apart hundreds of creatures with every passing second. The carnage wreaked among them was fearsome and hundreds of falling black objects drifted from the swarm. He wondered how they could possibly take so much punishment and still keep coming.

  In perfect synchrony, a portion of the swarm dipped and flowed from the sky as another climbed, heading for the high peaks of the city. The lower swarm rapidly lost altitude to skim the ice and race towards the trenches like dark bullets.

  The Hydras continued to spray the air with shells, the barrels depressing as the swarm heading for the trenches descended. The range was closing rapidly, the chittering screeches of the aliens clawing at the nerves of the thousands of men facing them.

  Pavel watched the aliens through the scope of his lasgun, the blinking red crosshairs flashing to green as the aliens entered the weapon’s lethal range.

  ‘Fire! Fire at will!’ bellowed an officer, and thousands of las-guns opened fire simultaneously. The black swarm jerked, hundreds upon hundreds of the beasts cartwheeling into the ice. Disciplined volleys pierced the swarm. Pavel fired without aiming. It simply wasn’t necessary when the enemy came at you in such numbers.

  The alien screeches rose to a howling gale and suddenly they were upon them.

  Vadim ducked as a flying monster smashed into the lip of the trench, vestigial rear limbs scrabbling for purchase on the ice. Membranous wings flapped as its ribbed arms pointed towards him, a slime-dripping symbiotic weapon aimed at his heart.

  Pavel shot the beast in the head and its thrashing carcass fell into the trench. A pair of hissing monsters swooped low, gobbets of black slime spattering the trench walls as Pavel pushed Vadim to the slush at the bottom of the trench. He rolled as the beasts came at him, oblivious to the screams and sounds of battle echoing from all along the trench line. He opened up on full-auto, filling the trench with bright lasbolts and cutting the creatures in two.

  Vadim shot another beast as it clawed its way over the snow berm. He dragged Pavel to his feet. The air was thick

  with gargoyles, swooping and diving at the trenches, clawing and biting and firing their disgusting bio-weapons. Screams tore through the hissing of the monsters and the air reeked with the stench of blood and fear.

  A clutch of the screeching beasts swooped down from the thinning swarm, bright spurts of bio-plasma melting snow and flesh with equal ease. Vadim screamed as he was lifted into the air by a gargoyle, his legs thrashing and his cries piteous as he was carried from the trench. Pavel jumped, grabbing hold of Vadim’s legs, but his thick mittens couldn’t get a grip and his friend was carried into the sky. Pavel fell back into the trench as another gargoyle swooped towards him. He dived to one side, desperately bringing up his lasgun to block its sweeping claws. Sparks flew as the alien’s talons hacked through the barrel, ripping through his overwhites, but tearing free before cutting into his chest. He stumbled, falling to his ramp on the firing step. He hurled his useless weapon aside, reaching for his war-knife as the beast spun in the air and came back for another pass.

  Alien gore spattered him as the gargoyle exploded in midair, detonating from within as it was struck by a burst of fire from a Space Marine’s bolter. He wiped dripping ichor from his goggles in time to see an Ultramarines captain and sergeant fight their way down the length of the trench, killing aliens and shrugging off their attacks as if they were on the parade ground.

  ‘Thanks,’ blurted Pavel, but the warriors had already moved on.

  He dropped to his knees, retching as the reality of his near death flared and shock began to take hold. Sick dread filled him and hot fear dumped into his system as he realised how close he had come to leaving Sonya a widow.

  He felt his limbs shake and rooted amongst the dead on the floor of the trench for a weapon, realising that action was his only hope of staving off the onset of this paralysing fear.

  Pavel hurriedly loaded the lasgun, and surged to his feet. He clambered back to the firing step and fired into the mass of creatures boiling in the air above him. He fired and reloaded, losing count of how many power packs he slammed home, resorting to taking more from the pouches of the fallen when his own ran out. But even he could see that the swarm’s numbers were diminishing.

  Unable to land and fight, the gargoyles could never capture the trenches, and Pavel wondered what exactly the point of this attack was.

  The answer was horrifyingly clear. The aliens were probing them… learning. This attack was nothing more than an exploration of their prey’s capabilities, the merest hint of what was to come. This vanguard was a diversion only, and the beasts that died here in their thousands were expendable, fodder to be used in order to decide how best to defeat the creatures that defended this world.

  The thought of such a cold, unfeeling logic chilled him to the core. If thousands might be sacrificed for the merest scrap of information, what more horrors might the aliens’ leaders unleash?

  The sounds of battle were beginning to diminish and here and there, Pavel could see the armoured forms of the Ultramarines and the Mortifactors despatching the last elements of the swarm, moving and firing their cumbersome weapons with an efficiency that came from decades of constant practice.

  He steadied himself against the side of the trench as a crippling wash of sensations flooded him. Relief at his survival, an ache for his family and grief for Vadim – though he had no idea whether his friend was alive or dead.

  He slumped to the trench’s firing step as exhaustion filled his limbs with cold lead and his hands started to shake.

  Pavel wept for his lost friend and the tears turned to ice on his cheeks.

  SNOWDOG LET RIP with a huge burst of fire from the heavy stubber, the shells cutting a hissing gargoyle in two and sending it tumbling from the boarded-up window it had been attempting to batter its way through. Silver calmly double-tapped another as it tore at a hole in the ceiling and Tigerlily spun and wove her way through the aliens, tearing wings and plucking out eyes with her thin daggers.

  Jonny Stomp and Trask fought back to back, blazing away with their purloined weapons at the bizarre-looking creatures that were trying to bust into their warehouse hideout. The guns’ reports were deafening, and cries of panic and fear from those civilians who’d been lucky enough to reach the safety of the warehouse dopplered in and out of perception between the blasts of fire.

  The doo
rway timbers finally splintered and half a dozen screeching monsters fought to get through the opening. Snowdog spun and braced himself, keeping his stance wide as he depressed the firing stud on the textured grip of the heavy stubber. A metre-long tongue of fire leapt from the perforated barrel and annihilated the aliens in a blood-and-smoke stained cloud. Even braced, the recoil staggered Snowdog, the stream of shells ripping upwards and blasting chunks of the plaster ceiling loose.

  He swung the gun back down again, searching for fresh targets, but, for the moment, finding none. The panicked whimpers and muffled sobs from the two-dozen civilians at the back of the warehouse were already irritating him and he let out a deep, calming breath, running to the edge of the shattered window frame to risk a glance outside.

  Since early evening, the roaring of defence guns had echoed from the valley sides and he’d watched the tops of the rock faces erupt in a furious storm of gunfire. At first he couldn’t see what they were shooting at, but pretty soon a billowing cloud of creatures came into view. Trailing the monsters came a black rain, spores in their thousands, dropping towards the city at a terrific rate.

  Explosions painted the sky, shells bursting amongst the dropping organisms and killing thousands of aliens. Snowdog had never seen such a magnificent display of the city’s defences before, and the firepower they brought to bear on the spores was nothing short of incredible.

  The scale of the tyranid invasion was of an order of magnitude greater than the city’s architects had ever bargained for, and scattered pockets of the aerial bombardment were able to penetrate the umbrella of flak, mostly in the lower reaches of the city, far from where the extra guns studding the walls of the Imperial Palace of Sebastien Montante defeated the first wave.
