The chaotic battlefield was a charnel house of death and discordant screams, yet near the fortress walls, a pocket of eerie, focused violence existed where only the roar of the duel and the deafening clang of god-like weaponry could be heard. The wider carnage of the Spire Plains seemed to shy away from this zone; no living being—mortal or daemon—dared to intrude upon the circle of the masters.
Abaddon's roar echoed relentlessly beneath the shadow of the high wall. He moved like a localized storm of destruction, the Talon of Horus and the daemon-blade Drach'nyen weaving a lethal, interlocking trajectory around his massive frame.
Alexei, Celestine, and Garadon launched their coordinated assault from three vectors, but the Warmaster's combat prowess had been honed to a razor's edge over ten thousand years of continuous slaughter. Fueled by the profane blessings of the Four Gods, every parry he made was accurate to the millimeter, and every riposte carried enough kinetic force to shatter ceramite and bone alike.
"You truly believe the three of you can cast me down?" Abaddon grinned, a mask of pure malice as Drach'nyen swept in a wide, singing arc that forced Celestine's holy blade back. Simultaneously, the Talon of Horus slammed into Garadon's power hammer. The sheer impact sent a shockwave through the ground, forcing the Imperial Fist Captain to retreat, his boots carving deep furrows in the scorched earth.
Alexei seized the opening, triggering his internal time-acceleration and thrusting his power sword toward the Despoiler's exposed flank. However, Abaddon's instincts were preternatural. He twisted with impossible fluidity, dodging the strike and delivering a crushing kick to Alexei's chest that sent the Governor hurtling backward once more.
"Damn it..." Alexei hissed as he hit the ground. He struggled to find his footing, the agony in his chest sharpening into a suffocating pressure. Every breath felt like inhaling shards of glass.
Nearby, Captain Garadon was in no better state. He leaned heavily on his hammer, blood gushing from between his gritted teeth and pooling on the dirt. His primary heart was stammering, and he felt as though his lungs had been pulverized by the kinetic transfer of Abaddon's blows.
Garadon's gaze flickered to Alexei. To the shock of the elite Astartes, this mortal commander—who lacked the protection of power armor—had done more than just survive; he was repeatedly standing back up after taking hits that would have crumpled a Space Marine. Is he even human? Garadon wondered. Or is he merely some unknown predator wearing a human facade? Among the four combatants, Alexei appeared the most fragile, yet his tenacity was frightening. After suffering several blows that should have been fatal, he was once again pulling himself upright.
On the field, only Saint Celestine fought with escalating ferocity. The golden light radiating from her form grew blinding, threatening to swallow the darkness that clung to Abaddon. Shouting the Emperor's name as a battle cry, she launched herself into the fray again and again, a living avatar of divine retribution.
Between the clashing of light and shadow, the duel reached a fever pitch. But the situation deteriorated as a fresh wave of Justaerin Terminators—Abaddon's elite veterans—broke through the Cadian interior lines atop the wall. They descended like an iron torrent, their power weapons and heavy bolters reaping a bloody harvest as they moved to surround the three heroes.
Alexei looked up toward the command tier, searching for Creed. To his relief, the Terminators attempting to reach the Lord Castellan were intercepted by Marshal Amalrich and his Black Templars. The High Lord was safe for now, shielded by a wall of black ceramite and righteous zeal.
Suddenly, the Justaerin charge was halted by a new arrival. A group of spectral Astartes, their armor wreathed in flickering, otherworldly flames, materialized from the mists. The Legion of the Damned had arrived. Without a word, the silent specters charged the traitors, meeting the iron torrent with the cold fire of vengeance.
Alexei took several ragged breaths, feeling the unnatural resilience of his body knitting his tissues back together. He watched the stalemate between Celestine and Abaddon, then looked at the spectral melee of the Cursed Legion. He spat a mouthful of bloody foam and gripped his power sword. "Again!" he growled, his figure blurring as he lunged back into the center of the storm.
Captain Garadon attempted to follow, but his shattered ribs and internal hemorrhaging made every movement an ordeal. He hesitated, realizing he could no longer keep pace with the duel, and diverted his path to support the Legion of the Damned against the Justaerin.
Aboard the high wall, Creed stood his ground. He bypassed the swirling melee between the Templars and the traitors to stand at the edge of the ramparts. He would not hide. Every Cadian needed to see that their Lord Castellan was still there, standing with them until the very end.
"So that's it! I see... I finally see!"
Deep within the catacombs beneath a Blackstone Obelisk, Archmagos Belisarius Cawl worked with manic speed. Under the cryptic guidance of Trazyn the Infinite, Cawl's mechanical appendages flew across the ancient Blackstone interfaces. Beside him, Magos Kran watched in binary confusion, his logic circuits unable to follow Cawl's erratic leaps of genius.
Nearby, the Necron Overlord was occupied with a servo-skull. Trazyn held the human device as it buzzed and clicked in a futile attempt to escape his metallic grip. Curiously, he began plucking out its exposed wiring until the device went limp and silent.
"What are you doing?!" Magos Kran hissed, tapping his mechanical staff against the floor in annoyance.
"Oh, do not be so sensitive. I am merely curious about this primitive little specimen," Trazyn replied airily. He was, in truth, bored. The arrival of the "Aiur" reinforcements had stabilized the battlefield beyond his expectations, requiring less direct intervention from his collection.
Suddenly, Trazyn's gaze shifted to a figure visible on his remote sensors near the bastion wall. For a fleeting second, he sensed an aura he recognized—and loathed—emanating from the commander named Alexei. Then, it vanished. "Intriguing..."
"Stop your bickering! I have it!" Cawl shouted, his voice echoing through the chamber. Kran let out a string of binary grumbles: You are the loudest thing in this tomb.
As Cawl made the final adjustments, the Blackstone pylons across the entire world of Cadia began to throb with a low-frequency hum. A massive, invisible force field began to expand from the obelisks at a terrifying rate. "I've done it! I've reversed the polarity! The negative shift is active!" Cawl's four arms flailed in triumph. "It works! You despicable, alien genius! We've won!"
However, his jubilation was cut short. His sensors picked up a sudden, agonizing wave of bio-data from the humans near the cave entrance. They were collapsing, wailing in sudden, inexplicable pain.
"No... no! Trazyn, is this expected? How long will this last?" Cawl froze, looking for the Overlord, but the Necron had already phased away into the shadows of the cave.
Alexei, locked in a desperate exchange with Abaddon, felt a sudden, crushing shift in the air. He looked toward the horizon as the force field swept over the plains.
The effect was instantaneous and horrific. The Living Saint and the Warmaster froze mid-strike as the field enveloped them. Celestine let out a strangled gasp; the golden light and holy flames that defined her essence flickered and died. She slumped, her connection to the Emperor severed, leaving her as nothing more than a frail mortal woman in heavy armor.
Abaddon, too, recoiled. He roared in agony as the voices of the Four Gods were silenced. The Warp-energy that fueled his strength was being violently pushed out of the materium by the Blackstone's anti-psychic pulse.
Across the distant battlefield, the daemon hosts simply ceased to exist. Thousands of warp-entities vanished in a heartbeat, leaving the remaining Black Legion veterans standing alone and bewildered. For the mortals, the sensation was different but no less traumatic. Every Cadian felt a heavy, soul-crushing weight settle upon them. Blood leaked from noses and ears; it felt as if thousands of needles were being driven into their brains. They collapsed into the mud, howling in collective agony.
Beneath the wall, Garadon staggered back. The spectral warriors of the Legion of the Damned had vanished as if they had never been there, leaving him alone against dozens of confused but still deadly Justaerin. Garadon didn't hesitate; he turned and used a pile of rubble for cover as he withdrew toward the Cadian regrouping points.
On the ramparts, Creed caught a collapsing officer. He wiped blood from his own face, his head throbbing with a psychic migraine he couldn't explain. At that moment, a crackling vox-transmission from Belisarius Cawl reached him:
"The Pylon field is active! The Warp is being suppressed! Caution: the side effects on non-augmented humans will be severe!"
