The severed head hummed faintly in One's grip.
Its glow had dimmed to a dull, unstable pulse. Pollution leaked from its broken facial disk in thin vapor trails before dissolving into the heavy air.
One walked several meters from the crater and placed the head atop a fractured slab of concrete.
Proof.
The wind shifted.
Not naturally.
The pollution did not drift in lazy spirals anymore. It pulled inward… then released. As if something unseen nearby was breathing it in and exhaling it slowly.
The ground beneath his boots vibrated faintly — not from movement, but from pressure imbalance. The Warframe's internal filtration systems flickered, recalibrating against unseen fluctuations.
Somewhere nearby—
A structure creaked.
But no debris fell.
Silence thickened.
Even the distant mechanical hum of the sanctuary felt muted, swallowed by the density at the edge.
One turned and scanned the wasteland stretching outward in fractured silhouettes and skeletal ruins.
The pollution here moved differently now.
Not just thick.
Disturbed.
It had watched everything.
From the moment the first laser split the air.
From the recoil of thermal rounds.
From the shoulder cannon's detonation.
From the saber's execution.
It stood where light did not reach — pressed flat against the underside of a collapsed structure.
It was terribly thin.
Its body resembled carved obsidian fused with bark — layered, ridged, rough like ancient tree skin turned black. No eyes marked its face.
Only two large, bat-like ears twitched subtly.
It did not blink.
It did not breathe in rhythm.
Its rib-like frame expanded irregularly, drawing pollution through thin slits along its bark-like chest. The energy did not swirl violently like the first creature.
It settled.
Controlled.
Stored.
Its ears reacted not only to sound but to minute distortions — the scrape of cooling metal on One's armor, the faint hum of recharging energy cells, the microscopic crackle of corrosion spreading beneath damaged plating.
It memorized patterns.
The delay between charge cycles. The half-second stabilization before shoulder discharge. The micro-shift in stance before rifle recoil.
It learned.
It knew the shoulder cannon required buildup. It knew the Warframe was strongest at range.
So it would not allow range.
Its form blurred.
Then vanished.
Not faded.
Gone.
Even the pollution currents did not cling to it.
It moved.
Silently.
Closing in.
One took a step forward.
Then paused.
The pollution density around him shifted.
Subtly.
Like a single drop disturbing still water.
His Armament stirred instinctively.
The Warframe's intake vents flickered as he adjusted stance.
Behind him—
Air displaced.
The creature reappeared mid-lunge.
Its right arm had lengthened into a narrow, curved blade of blackened bone and obsidian. The edge vibrated with microscopic serrations.
It aimed directly for the exposed neck seam.
A perfect kill angle.
For any other mutant—
It would have been over.
One twisted instantly.
The blade grazed his shoulder instead.
Metal shrieked.
A layered sound — grinding alloy, vaporized fragments, brittle cracks spidering outward.
Heat flooded across his right side. Warning lights flared red inside the cockpit.
Armor compromise: 61%.
The creature vanished before recoil finished echoing.
One fired blindly.
Thermal rounds shredded empty air.
Nothing.
The pollution shifted again—
Left.
He pivoted.
Too slow.
A blade erupted from beneath, slicing across his thigh actuator. Hydraulics ruptured with a violent hiss.
The Warframe staggered.
Armor compromise: 68%. Mobility impaired: 12%.
The creature did not linger.
It struck. Disappeared. Reappeared.
Each attack surgical. Each angle deliberate. Each retreat clean.
The worst part was not the strikes.
It was the silence between them.
No breath. No footstep. No friction against debris.
The Warframe's sensors swept in widening arcs.
Nothing.
Then pain.
Another slash carved across his upper plating.
Corrosion spread instantly from the wound. Blackened veins crawled along the inner armor surface like invasive roots.
Armor compromise: 79%.
The creature was not testing him.
It was dismantling him.
One attempted to bring the shoulder cannon to bear.
The creature reacted instantly.
It materialized above him, legs morphing into twin spear-like extensions, slamming into the cannon housing before it could charge.
Mounting bolts sheared off with metallic snaps. The cannon drooped at a useless angle.
Shoulder cannon alignment: critical error.
It had learned.
It would not allow heavy discharge.
It remained inside minimum firing range.
Herding him.
One switched to rifle configuration and unleashed a sweeping barrage.
Again—
Nothing.
A ripple in pollution.
Then absence.
The next strike came from behind.
A blade pierced partially through back plating, stopping just short of the cockpit.
The grinding intrusion was worse than impact.
The creature withdrew cleanly.
Vanished.
It wanted a one-shot kill.
It prolonged the fight deliberately.
Every strike aimed at joints. At seams. At actuators.
Never random.
Always lethal.
A horizontal slash fractured his visor.
Cracks branched outward, distorting light into warped segments. The battlefield split into fractured reflections.
The creature reappeared ten meters away.
Still thin. Still eyeless. Still silent.
Its tongue extended slowly.
Then elongated.
Split.
Hardened into twin needle-thin blades.
It crouched.
Then vanished completely.
Not even pollution currents betrayed it now.
The Armament inside One pulsed urgently.
Ahead.
The density collapsed inward violently.
Incoming.
Fast.
Too fast.
His damaged leg actuator struggled to respond. Hydraulics ground under strain.
Time did not slow.
His mind simply tried to survive.
Shoulder cannon disabled. Mobility impaired. Armor critical. Opponent unseen.
The creature reappeared mid-thrust.
Its entire right arm had transformed into a massive, straight obsidian sword — longer than his torso, razor-thin, perfectly aligned.
The blade made no sound.
It reflected fractured red light across his cracked visor.
He saw himself in it.
Distorted.
Small.
The tip aligned with the weakest seam of his faceplate.
No angle to twist. No time to evade.
The blade cut forward in absolute silence.
For the first time—
One did not calculate.
He did not strategize.
He felt something primal crawl up his spine.
Fear.
Not of pain.
Not of defeat.
But of sudden erasure.
Of ending without understanding.
The sword closed the final distance toward his face.
And in that suspended second—
He knew.
If not for his Armament sensing that shift earlier…
He would already be dead.
The blade reached him.
