Sedition's Gate - Nick Kyme & Chris Wraight

by Warhammer 40K

  In the following five elapsids, the Omnissiax suffers a series of catastrophes the like of which its operational history has not known in a thousand years of service.

  Radiation leaks erupt on deck four and sub-decks five through eight. Reserve coolant chambers for the ark freighter's plasma drive are evacuated, cold-flooding parts of the engineering section and initiating a sequence of further malfunctions. For a moment the torsion coils, cooling after warp translation, register a Geller field spike so profound that the magos empyr initiates a code-vermillion shutdown of all associated systems and sections. An electromagnetic pulse in the open-core ionisation cell stack causes sporadic power and vox transmission loss throughout the ark freighter, while artificial gravity experiences an unexplained calibration flux and

  continues to do so, reducing or intensifying agency by as much as twenty-five per cent in different parts of the vessel. Several exterior voidlocks, situated both port and starboard, are blown, transforming access ways and chambers from a howling maelstrom to a labyrinth of closed emergency bulkheads. Rune banks relay false probabilities, indicating that the hull breach was likely caused by the Omnissiax passing through a particle storm, probably the tail-wake of a traversing comet.

  By elapsid/tau-xi-alpha, the priests, enginseers and auto-savants rushing about the vessel are officially overreached by the myriad calamities now afflicting their ship.

  Logista Minora Auxabel is not one of them. She is doing exactly what she is supposed to be doing under the circumstances - rapidly assimilating the data-storm from her cipher engines and drawing logical conclusions. At elapsid/tau-xi-theta, she transmits her assessment to Arkmaster Manus Cruciam and Magos Dominus Oronti Praeda.

  Conclusion: the Omnissiax is under attack.

  In such circumstances, overall command reverts to the magos dominus. There isn't even need of a discussion.

  In all likelihood the target of the attack is deemed to be the ark freighter's precious cargo, rather than the ark freighter itself, rendering Manus Cruciam's authority superfluous to command priorities. The arkmaster takes his place with Logista Auxubel. Their duty is to get the Omnissiax fully functional, as soon as possible. With the vox transmission and noospherics of all security thralls, gun servitors and roaming servo-skulls patched through the communications of Oronti Praeda's ward force, the enemy's movements are then fed straight back to the Alpha Legion through their planted sparatoi agents.

  Agents like this unit, 55/Phi-silon.

  As the strike commander predicts, the magos dominus does not waste time in following his own protocols and taking precautionary measures. Ordnamats are scrambled to the weapons short-decks,

  and the ark freighter's meagre complement of defensive cannonry is charged and run out. Security on the bridge is tripled, and the ward force of Collegia temple-thralls, Thallaxii shock troops, Legio Cybernetica battle automata and tech-guard of the Seventh Cell-Sentinel Entropriad are directed with all despatch to the payload sections and the cargo bays. Seeing that they are led by the veteran skitarii Arch-Tribune Dynamus Koda and funnelled through the accessible sections and passageways, Dartarion Varix sends his Alpha Legionnaires to meet them.

  Elapsid/omega-xi-zeta sees the first official exchange of gunfire between the Legiones Astartes aboard the Omnissiax and loyal Mechanicum forces. Psi-Sigma IV-of-XI loses his artificially augmented life to Legionnaire Phasal Scolton of the First Hort, Third Harrow. As a living auspex, Psi-Sigma IV-of-XI had been leading advance skitarii squads of the Seventh Cell-Sentinel Entropriad through the crew domiciles. Scolton had ordered flamers used on the quarters before having his legionaries withdraw. As the Mechanicum ward force advances, the intense heat and the flames renders main auspex frequencies useless. The Alpha Legion withdraw within the inferno, their battleplate offering more protection against the flames than their enemies can expect.

  Slowly, calmly, Legionnaire Scolton leans around the passageway apex and brings his boltgun level with Psi-Sigma's hooded, optic-bulbous head. By the time the construct is ready to confirm a lifesign, Scoltan's finger is on the trigger.

  The blast of bolt-fire cuts straight through the living auspex, before chewing up the Entropriad skitarii behind who shield their vulnerable organics from the flames. The Alpha Legion weave their way confidently through the domiciles in alternating columns, slamming their pauldrons into cover whilst watching over their opposite numbers as they advance. The choreographed tactical advance is a thing of serpentine beauty. Phased plasma fire and las-beams slice through the flames from the disciplined ranks of skitarii, but the Legion will not

  be denied. Their advance is murderously economical. Every blinding lick of flame and every obstructive piece of cover is their ally.

  The Entropriad, undoubtedly veterans in their own class, do the only thing an enemy of the Alpha Legion can do.

  They die.

  By elapsid/khi-nullus-delta, Arch-Tribune Dynamus Koda has watched enough lifesigns fade on his intracranial display that he orders the Castallax battle automata of the 13th Maniple Proxim/ Mephistra Cohort into the flames.

  Several decks below and running parallel to the Phasal Scolton's advance, Dartarion Varix and a squad of the veteran-hort legionnaires wade through coolant on the flooded sub-decks. I am with them. The syrupy darkness of the fluid cascades down through the levels as maintenance floor-hatch after maintenance floor-hatch is pops, and the Alpha Legion make their way down through the ship.

  There are encounters. Servo-drones hurtle up corridors, filling sections with flashing lamps and the wail of klaxons. Groups of gun-servitors march their way past with cybernetic indifference, all unsightly with enhancement and baggy flesh. While canopy formations are maintained and boltguns aimed, Varix has his legionnaires retract behind cover or sink back into the shadows. All constructs on board the Mechanicum vessel will die - the strike commander has so ordered - but the Alpha Legion are not given to moments of rash opportunism. The unplanned end of one enemy might put at risk the meticulously arranged end of a thousand more. There is no glory in the individual death, only the communal honour of a victorious action executed to perfection.

  Once down in the bowels of the ship, the ancient sludge of the bilge smearing their armoured boots, I lead my Alpha Legion masters to what on bank schemata is labelled as the fore-keel trunk distribution nexus. On a diagram grid it is nothing more than a 90/120 peta-watt power drain associated with a malfunctioning flush drive that was

  4,263rd of 16,457 in a rolling programme of maintenance repairs, and scheduled to be addressed post-voyage. Standing before it in the frosted sludge, with methalon gas drifting through their number like a moorland mist, the Alpha Legion find what they are looking for.

  A jury-rigged iso-store of ten cryopods. A team of sparatoi agents that they have sown deep within the ship. I get to work immediately, initiating a rapid thaw. There is no standing on ceremony. Varix and his legionnaires also pitch in, disconnecting pipes and cables, bringing their very own Titan crew back from the brink of semi-death.

  'How long?' Varix demands.

  'Once out of containment,' I tell him, 'Princeps Darrieux and his crew are scheduled to have two hours with Abyssus Edax for core cycles, interfacing and spiritual observance.'

  'How long to simply jack the god-machine?' the strike commander puts to me.

  'What do you need, my lord?'

  'Automotive function and weapons systems only,' Varix insists.

  'Forty-five...' The dead-eyed optics of the strike commander's helm turn on me. I hastily revise my estimate. 'Twenty minutes, my lord.'

  'Time elapsed since mission start?'

  'Elapsid/khi-rho-iota-epsilon,' a legionnaire tells him.

  With the thaw cycle initiated, Varix and his veteran-hort begin to exit the chamber and push on through the ark freighter bilge.

  'Explain to Princeps Darrieux the new constraints of our situation,' Varix tells me. 'As per his original orders, he is to bring his crew up through the forge-temple sump duct
s. My legionnaires will engage the temple guard and give him the distraction he needs to get to the Titan. I want Abyssus Edax operational and ready to enact firing sequences in twenty minutes. Understood?'

  'Yes, strike commander.'

  'When all this is done, bring me the telepath Quorvon Krish.'

  With that, Dartarion Varix is gone.

  Elapsid/khi-tau-kappa-delta. The Omnissiax is in a state of

  controlled chaos. Though neither the legionnaires of the XX nor the constructs of the Mechanicum are given to such descriptions, it remains an undeniable fact that the ark freighter is suffering a cascade of malfunctions while being ripped apart from the inside by firefights and explosions moving through the decks.

  For Magos Dominus Oronti Praeda and Logista Minora Auxabel the surprise attack is a sudden influx of new data to be addressed within a cold and ongoing assessment. For Strike Commander Dartarion Varix it is satisfaction denied: the promise of victory in every boom and scream. It is the clunk-click perfection of a chambered round, the slick mechanical unity of all parts working together and acting as one. Death premeditated. The sickening realisation of the target in sight. The disorientation of the muzzle's thunderous announcement. The shock. The pain. The rich futility of the moment in which an enemy knows that they are done. Then, the neatness and artistry of death. Only then does the killing come to an end and the Alpha Legion allow themselves the cool pride - and perhaps even pleasure? - of reporting a mission accomplished.

  And so the relentless havoc unfolds. I have sent the Titan crew on with their orders. The telepath Quorvon Krish is by my side. Together we report to our strike commander.

  At elapsid/khi-upsilon, tech-adepts of the 13th Maniple Proxim/ Mephistra Cohort report unacceptable losses in the crew domiciles. Later analysis would attribute these losses to a winning combination of Banestrike ammunition, shredding its way through the automata plate and workings, and expert marksmanship. In particular, kill-shots targeted the constructs' crania-canopy and the vulnerable neural cortex beneath. Arch-Tribune Dynamus Koda is forced to once again plug the gaps created by fallen Castallax automata with skitarii from the Seventh Cell-Sentinel Entropriad. The situation becomes so dire that the Arch-Tribune himself must take up arms. It has been six years, two hundred and fourteen days and

  twelve minutes Terran-standard since the skitarii commander has personally fired a cybernetic attachment.

  He does not receive the honour of doing it again.

  Legionnaire Phasal Scolton blows the back of his head out with an economical burst of fire from a concealed position in the dark recesses of a maintenance booth. Skull and fragments of intracranial tech shower the passage. By elapsid/khi-upsilon-kappa-theta, Koda's own auspectral signature is confirmed lost and skitarii sentinel Inx Voltar is cursorily promoted to the rank of sub-tribune. At Magos Dominus Praeda's insistence, Voltar's first recorded act of leadership is to order the Entropriad to withdraw to the forward hold. It is not considered by the sub-tribune to be a decorous act, but he complies with his protocols regardless.

  Concurrent with the unstoppable slaughter rolling through the crew domicilia, Logista Minora Auxabel receives a data-confluence of further hostilities. Limited surveillance coverage identifies enemy contingents wearing Mark IV battleplate. Fragmented reports bear witness to rank, insignia and Legion colours. Auxubel calculates for the magos dominus only a thirty-seven point six per cent chance that the enemy belong to the XX Legion. This estimate is based on incomplete capture-testimony, and what little information the Mechanicum runebanks hold on the Legion's operational histories during the recent movements of the Great Crusade. Nonetheless, it is the greatest likelihood at her disposal.

  Oronti Praeda demands further enhancement and tactical options but the logista has little to give him. Having fought alongside the Alpha Legion at Cypra Chasmis, the magos dominus knows that the XX favour the long game and calculates that the best chance for the beleaguered Omnissiax is to hit the Legiones Astartes with everything they have in one devastating push.

  At Praeda's command, any construct with a martial rating of any description is ordered into battle. They are directed to the emerging hostilities near the temple forge section of the forward hold,

  and to the starboard auxiliary gun decks where enemy targets have been observed entering through malfunctioning voidlocks from outside the ship. They are also directed to the portside flight decks where security thralls are being decimated among the skiffs and freight ambulatories, and to the sub-levels where gun servitors and electro-priests of the Battle Group Astramax-attendant 'Grex Anbarica' hold their ground against targets emerging from maintenance decks. As the firefight rages several levels below their boots, Praeda considers it prudent to despatch a Thallaxii cohort of cyborg shock troops to crush the rising advance.

  'What of our own security?' Arkmaster Manus Cruciam asks across the bridge, his voice clearly audible to me through the noospheric link. It is not an unreasonable question. Beyond auspex-drone weaponry, only deck thralls and Praeda's personal ward engines remain.

  'Our security,' the magos dominus tells him, 'nay, our survival, depends upon the Omnissiax reaching Callistra Mundi as soon as possible.' Logista Auxubel nods her slow agreement. 'Preoccupy yourself with that, arkmaster.'

  Like a ceramite gauntlet, the Alpha Legion have the ark freighter in their grasp. With every bolt-smashed construct and every scoured section, Dartarion Varix tightens his grip. Alpha Legionnaires of the First Hort, Third Harrow weave their way through the expanse of the ark freighter like serpents through the undergrowth. Little stops their advance - not the vessel's souless thralls, not the battle-automata with their lumbering movements and limited protocols and not the battle-hardened skitarii. Elapsid/khi-phi becomes elapsid/khi-omega. Elapsid/khi-omega becomes elapsid/betakhi-rho. With each passing second, Mechanicum constructs die. Some are blasted apart in showers of hydraulic fluid and shattered components, while others simply thud to their knees as Alpha Legionnaires put single bolt-rounds through skulls and central cogitators alike.

  Veterans of First Hort, after exiting the vessel and climbing along the exterior hull, now re-enter through blasted voidlocks. As they

  progress through the side of the ship like a burrowing worm, they open bulkheads before them and evacuate entire sections of Mechanicum warrior-constructs, who are dragged and dashed along the trail of howling corridors that the Alpha Legion left in their wake. For these unfortunate servants of the Omnissiah, only the frozen void beckons.

  Gradually, moment by moment, even with staid reports of rapid successes pouring in over the vox-channels, this unit deduces that Dartarion Varix begins to feels denied. He misses the screams. The begging seems strangely absent. The blood-soaked intensity, the futility and the desperation that the Alpha Legion creates in enemy forces is found to be lacking in the cold, calculating servants of the Machine-God. Even as Varix and his legionnaires put bolt-rounds through the dead, oil-black eyes of servitors and the iron masks of tech-thralls, the constructs make no sound but the crash of their augmented bodies on the deck. Bolt-blasted battle automata grind to a statuesque halt, while even the psycho-indoctrinated skitarii merely give a grunt as the air of their last breath escapes their artificial lungs. The strike commander is no fear-hungry Nostroman monster, nor one of Fulgrim's deviant Children. The howls and anguish of the fallen are not a perversity to be savoured. For the Alpha Legion, executing the enemy, their mission directives and their duty with peerless skill, the screams of the dying are simply a professional courtesy.

  At elapsid/betakhi-rho-gamma-digamma, Alpha Legionnaire Duceus Ladon dies right next to his strike commander. Thrall soldiers on the stairwell part to admit the Thallaxii - cyborg shock troops, armoured from head to foot in powered plate. The crackling arcs of their lightning guns sear down through the stairwell to cook Ladon right there in his armour. Varix snarls. It is a waste. Ladon was an excellent legionary, and had served with him on his last five actions. Varix hears the heavy
clunk of the Thallaxii's ambulatory systems as they lock down their position.

  It is the first in a succession of losses for the strike commander.

  Elapsid/betakhi-rho-omicron-delta sees Legionnaire Argan reported dead in the forward hold, the victim of a skitarii grenade clutch. Elapsid/betakhi-sigma-mu-theta witnesses the passing of Orman Zalco, tom apart by the vice-claws of a Castallax battle automaton. Seconds later, Squad Sergeant Xantina is gunned down by a ceiling-mounted rotary cannon, its auspectral wetware returning unexpectedly to life as enginseers in some distant part of the ship begin to repair some of the damage done to the ark freighter's systems.

  The Mechanicum are unleashing everything they have in an effort to stop the Legiones Astartes in their tracks. Dartarion Varix expected as much of their commander. Indeed, the he is relying on such a strategic response. Warrior-victims of Alpha Legion assaults were like traditionally tormented, wild beasts - wounded and disoriented, they were most dangerous when they were near their end. Varix allows a thin smile to find its way across his face. Actions speak louder than words. He can suddenly see the suppressed emotion of the Omnissiah's servants in their tactical responses. They are losing their ship and becoming increasingly desperate. They are no longer safe in their data and equations. They entrust their survival to gambles and risks - even if they are calculated ones.

  'Armoured targets,' Varix announces over the vox.

  Immediately, sickle clips are exchanged in boltguns; Banestrike bolts will make short work of the armoured Thallaxii. In the bloodshot gloom of the stairwell with klaxons blasting and emergency lamps flickering on and off, Varix takes cover as streams of lightning blast down past him. The Thallaxii are not moving.
