This was only the beginning.
The toxic deluge had saturated the staging ground. The servitors—tasked with ammunition transport, maintenance, and auxiliary fire—suffered catastrophic losses. More than a third of the augmented laborers were slagged by the corrosive venom, reduced to steaming piles of scrap and charred organic matter.
The air in the hatchery grew thick with a pungent, acidic stench that burned the throat. More critically, the kinetic shields protecting the anti-Titan battery were failing. Under the relentless barrage of bio-shells, the emitters groaned—a dying wheeze of overworked machinery. The translucent field flickered erratically, threatening to vanish at any moment.
"Shield integrity at critical threshold!" the Skitarii overseeing the field-projectors reported. His mechanical voice carried an uncharacteristic jitter of static.
The Hive Mind did not miss the opportunity.
ROAR!!!
The Hierophant let out a triumphant, earth-shaking cry. It took another ponderous step forward, each footfall sounding like a death knell. Driven by this surge of synaptic command, the surrounding swarm—Hormagaunts, Termagants, and Rippers—launched a frenzied, suicidal charge against the Sons of Medusa's line.
Their goal was clear: interference. They would throw themselves into the muzzles of the guns to delay the next salvo. If the Bio-Titan secured even one unhindered opening, the human defense would be erased.
"Hold the line! For the Emperor! For our fallen brothers!"
Cassius's voice was cold as iron, yet it carried a hidden heat like molten lava. He swung his Thunder Hammer, pulping a Tyranid Warrior's skull in a spray of green ichor that coated his Storm Shield.
"All auxiliary fire, prioritize the breach! Heavy artillery, prepare for the second salvo!"
"Plasma at seventy percent!" "Multi-Meltas cycling—fifteen seconds!" "Missiles reloading!"
The reports crisscrossed the vox-channel as the battle entered its most brutal phase of attrition. The Sons of Medusa fought with the legendary resilience of their lineage. Bolters roared without ceasing; chainswords and power-blades carved a bloody storm through the chitinous tide.
Skitarii Vanguard and Sydonian Dragoons threw themselves into the gaps, using their very bodies to bolster the steel perimeter. Onager Dune Crawlers pumped rockets into the fray, and the Land Raider's Heavy Bolters sang a song of relentless destruction, even as its Flamestorm Cannons began to hiss with the heat of constant use.
Every second, a warrior fell. Whether a Skitarii was overwhelmed by scuttling claws or a servitor was dissolved by acid, the line held. Miraculously, it held.
Finally—
"Plasma fully charged!" "Multi-Meltas ready!" "Missile-lock confirmed!"
"FIRE!!!" Cassius roared.
BOOM!!
Beams of blinding white and azure light tore through the smog, slamming into the Hierophant's massive form with vengeful intent.
ROAR!!!
The Bio-Titan let out its most agonizing cry yet. Its thick carapace finally reached its limit. Large chunks of purple chitin melted and sloughed away, revealing the raw, pulsing biological tissue beneath. Four anti-tank missiles followed instantly, diving like precise scalpels into the open wounds.
Purple-green ichor gushed out like a waterfall. For the first time, the Hierophant staggered, its bio-cannons damaged and their charging cycle interrupted.
"It's working!" a soldier shouted.
Cassius, however, did not relax. He knew they were at the precipice. The heavy guns needed to cycle again, and the swarm's frenzy had reached a fever pitch. Both sides were gambling on who could strike the killing blow first.
Amidst the cacophony of the front line, an urgent report broke through.
"Target approaching! Three o'clock high! Extreme velocity!"
It wasn't a cogitator that found it, but a soldier's naked eye. Cassius snapped his head toward the organic dome of the ceiling.
A blurry shadow, almost perfectly camouflaged against the dark biomass, was plunging down. It moved in a silent, predatory arc—no heat signature, no energy fluctuation, not even the whistle of displaced air. It was a spear of death launched from the darkness.
"Intercept! Intercept that flyer!"
The Indomitable Terminators swung their heavy weaponry upward, tongues of flame licking the air as they saturated the flight path. Skitarii raised their galvanic rifles, weaving a web of energy.
Thump-thump-thump!
Only when the rounds struck did the figure reveal its outline. It was a Hive Crone, but far larger and more sophisticated than any Hive-fleet record suggested.
The heavy shells hit home, but the impact was bizarre. The creature's armor plates exhibited a "fragmentation-detachment" pattern, shattering upon impact to dissipate the kinetic force. When plasma beams scorched the purple-red shell, a faint shimmer appeared, dispersing the heat before it could penetrate.
"Reactive armor... and a thermal-resistant coating?" Cassius's pupils contracted. This was a level of biological engineering that mimicked the advanced defensive patterns found in Martian archives. This was guided evolution.
Sarah—the evolved queen—bore down on them. She locked onto one of the Terminators whose heavy weapon was mid-cycle. The bio-plasma cannon on her forelimb glowed with a lethal green light.
Pfft—BOOM!!!
A condensed sphere of plasma struck the Terminator's raised arm. The ceramite softened and ran like wax. In a heartbeat, the warrior's left arm and his weapon were reduced to a pool of molten slag.
Sarah didn't stop. She retracted her membrane wings and used her diving momentum to slam into the damaged warrior.
CRUNCH.
The impact was sickening. Under the sheer mass of her enhanced form, the Terminator's servo-systems shrieked in overload. The warrior roared, trying to fire his remaining weapon, but Sarah ignored him. Her claws—sheathed in ultra-dense chitin—tore through his chestplate like it was parchment.
The sound of twisting metal filled the air. With a brutal tug, she ripped open the support systems, exposing the Astartes warrior beneath. For a fraction of a second, the soldier's defiant face was visible before the claws drove back in, stirring through armor and flesh alike.
In two seconds, a veteran of the Sons of Medusa was dead.
"NO!!!"
Cassius watched the slaughter, his eyes turning bloodshot. A volcano of fury and grief exploded in his chest.
"XENO!!!"
He let out a roar like a wounded beast, his heavy boots pounding the fungal floor as he charged toward Sarah.
