Behind the lines of the Black Legion, atop a jagged, windswept ridge, Abaddon the Despoiler stood amidst his veterans of the Long War. He watched the distant carnage in silence. As the armored spearheads led by the Iron Warriors and the remaining Chaos Astartes plunged into the Imperial ranks, the plains became a slaughterhouse of grinding metal and screaming souls.
Seeing the momentum of his assault begin to falter, Abaddon did not waste breath on commands. He simply raised his chin and pointed his left hand—the Talon of Horus—toward the final bastion wall. In response to the Warmaster's silent decree, the Legio Vulcanum accelerated its advance, the wrath of the God-Machines pouring forth with renewed, apocalyptic intensity.
The armies of the Corpse-God seemed powerless to halt the stride of the Titans. Watching the Vulcanum relentlessly close the distance to the final threshold, Abaddon gripped the hilt of Drach'nyen tightly. "The final moment has finally arrived..." he hissed. If the pylon array anchoring the Eye of Terror could be shattered, the foundations of the Imperium would follow.
Suddenly, Abaddon's thoughts were cut short. His gaze snapped toward the warships descending through the clouds, a sudden, cold sense of foreboding rising within his chest. "Cyrone! Cyrone!" he bellowed. The sorcerer-advisor immediately rushed forward.
"Summon the Vengeful Spirit to our aid! At any cost! Do it now!" Abaddon's voice rose to an angry roar as he watched the center-mounted axial cannons of the fleet above rotate to lock onto the Legio Vulcanum.
High above, the laser arrays of the Aiur fleet ceased their scanning of secondary targets. The low-frequency hum of cold-fusion engines faded into a terrifying, heavy silence. The entire fleet appeared to enter a dormant state, all power diverted from non-essential systems to the primary weapon capacitors. Only the Void Shields remained active, glowing under the ineffective fire of the Titans below.
The battlefield fell into an eerie, expectant hush. The Titans continued their frantic bombardment, but the Imperial Scythes Chapter, recognizing the signs of an imminent orbital-grade discharge, realized the danger. Those terrifying axial muzzles were gathering energy.
Confirming the Despoiler's growing dread, the muzzles of the ships began to glow with a blinding, celestial light. Vast quantities of nuclear energy were compressed into the firing chambers, the atmospheric pressure dropping so sharply that everyone on the battlefield felt the hair on their skin stand on end. Under the frantic orders of the Lord Castellan, the Imperial forces engaged in close combat with the Titans began a desperate, scrambling retreat.
The Legio Vulcanum seemed to sense its impending doom. The Legion Commander's hysterics echoed over the vox as the Titans abandoned the fleeing Imperial infantry, turning their massive barrels toward the sky in a futile attempt to forestall the inevitable. They were too slow.
In the next heartbeat, all sound in the universe was drowned out by a colossal, mountain-shaking roar. The clouds above the Spire Plains were instantly disintegrated by a massive thermal impact. A dozen artificial suns bloomed in the sky, casting a light so radiant it threatened to burn the retinas of any who looked upon it. The violent shockwave that followed was so powerful it tossed Cadian soldiers aside like autumn leaves if they failed to find cover.
The Astartes on the field drove their chainswords and power weapons into the earth, leaning their weight into the gale to withstand the terrifying displacement of air.
On the high bastion, Creed followed Alexei's urgent warning and turned away just as the world turned white. Captain Garadon used his massive, armored frame to shield the Lord Castellan from the debris and the heat, his ears ringing with an endless, high-pitched buzz. When the light finally faded and the dust began to settle, the battlefield had been utterly transformed.
The Legio Vulcanum, the armored hordes of the Iron Warriors, the traitor Astartes, and the swarming cultists—all had vanished. In their place remained a dozen perfectly circular, glassed craters. The air shimmered with scorching thermal currents that distorted the very space above the impact sites. Not a trace of the enemy's main force remained.
"This... this is..." Creed stammered, his mind momentarily losing the capacity for speech. The control required for such a strike was incomprehensible—a scalpel-like precision that had annihilated tens of thousands of enemies without so much as singeing the uniforms of the Imperial soldiers only hundreds of yards away.
The Imperium possessed planet-killing weapons, but a strike this precise, performed by warships within the atmosphere without the need for pre-calculated ground coordinates, was unheard of. It defied every tenet of Imperial naval doctrine.
Creed stared at the devastation with a complex mixture of awe and suspicion. He turned to Governor Alexei, who stood nearby with his hands clasped behind his back, a faint, satisfied smile playing on his lips. Before Creed could demand an explanation for the origin of such weaponry, the sound of cheers erupting from below the wall broke his train of thought.
Surviving Cadians embraced one another, their voices hoarse as they shouted that their world would never fall. They wept openly; they had lost everything—families, comrades, and homes—to the invasion of Chaos. For days, they had held on by nothing but blind faith and desperation.
Now, on this scorched and scarred earth, they had achieved a true victory. They did not know if the enemy would return, but in this moment, they could finally shout the words with conviction: "Cadia stands!"
The Astartes on the field steadied themselves, exchanging silent, wary glances. Tarquill, Chapter Master of the Imperial Scythes, removed his helm and looked toward the high wall, his expression unreadable.
Garadon, still gripping his power hammer, watched Alexei's retreating figure. His mind raced with tactical assessments of the fleet's power, his expression shifting between respect and deep concern. Beside him, Saint Celestine watched the golden light of the fleet fade, murmuring softly, "So, you are the one of whom the Holy Father spoke..."
The peace was short-lived. Before her words had even finished, a chorus of guttural roars echoed from the depths of the distant plains. Abaddon had not conceded. The Black Legion's armored core was gone, but the Chaos Sorcerers had begun a blasphemous ritual. A terrifying wave of warp-spawned daemons, summoned from the very depths of the Empyrean, surged toward the Cadian lines. The soldiers were forced to cut their cheers short and return to the blood-slicked trenches.
At the rear of the battlefield, Abaddon's roar was one of pure, unadulterated fury. His Legion—the empire he had spent millennia forging—had been reduced to ash in a matter of seconds. Those damned, impossible ships! "AIUR! AIUR!!!" he screamed, the name of the fleet becoming a curse on his lips.
He had lost his most veteran brothers. Now, aside from the elite Terminator guard standing behind him, his ground forces consisted of nothing but the warp-horrors summoned by his sorcerers. He loathed relying so heavily on the fickle denizens of the Warp, but he had no choice.
Leading the last of his Justaerin veterans toward the open plains, Abaddon watched as the power of the Great Game surged once more. He would personally end the minions of the Corpse-God and the upstart commander who had dared to destroy his legacy.
