The hallway tilted beneath Mara's feet as she sprinted, her pulse hammering like a second alarm in her skull. Every light above them flickered violently, turning the world into a stuttering slideshow of terror.
RUN.
DARK.
RUN.
DARK.
Behind them, Sentinel Three barreled down the corridor like a locomotive made of bone and muscle, each impact of its limbs shaking dust from the ceiling.
Daniel shouted over the roar, "Left! Service tunnel!"
They veered sharply into a narrow passage half-lit by dying bulbs. Pipes overhead rattled from the vibrations. Even here, the creature's snarls echoed through the ducts.
Ten panted, "It's not stopping… it's tracking us— it's tracking you, Mara!"
Mara felt it too—
a strange, magnetic pressure,
like her body was calling the thing forward.
"Why me?" she breathed.
Evelyn's answer was grim.
"Because you're what replaced it."
A shudder tore through Mara's chest—
not fear,
but guilt that wasn't hers.
They burst into a wider maintenance bay filled with humming machinery. Daniel skidded behind a large generator, yanking Mara down with him.
"Quiet," he hissed.
They crouched, hearts pounding.
In the silence, they could hear it:
The sentinel sniffing.
Searching.
Hunting.
Then—
a deep metallic groan.
The corridor they'd just come from buckled outward as claws punched through the steel.
Ten muffled a scream. Evelyn held her close.
Daniel's jaw clenched. "It's tearing through walls now?!"
Mara felt her nerves blister with heat—
her power rising like panic,
but sharper.
Focused.
Not random like before.
This time she could feel the shape of it.
"Mara," Ten whispered, staring at her. "Your hands…"
A faint white glow spiraled around Mara's fingertips like mist caught in a breeze.
Evelyn breathed out, "She's stabilizing."
"I don't feel stable," Mara whispered back.
Before anyone could speak again—
BOOM.
The wall exploded inward.
Sentinel Three lunged through, jagged and massive, its skin stretched over biomechanical implants, its jaw unhinging with a screech that rattled Mara's bones.
Daniel fired.
Three shots slammed into the creature's torso—
it barely flinched.
It swung an arm the size of a steel beam toward them.
"MOVE!" Daniel yelled.
They dove aside as the impact demolished the generator, spraying sparks and metal shards. Mara rolled across the floor, ears ringing.
The sentinel turned toward her.
Mara froze.
Its dead-white eyes locked onto hers—
not with rage,
not with instinct,
but with recognition.
As if it saw its own replacement
and wanted to destroy it.
"Mara!" Daniel shouted.
But she couldn't move.
The creature leapt.
At her.
She raised her hands not out of strategy,
but out of raw fear.
The glow erupted instantly.
A shockwave blasted out of her palms—
silent, bright, instantaneous.
It hit the sentinel midair like an invisible freight train.
THUD.
The monster was thrown backward, slamming into the far wall so hard the entire bay shook.
Daniel stared, stunned. "Holy— Mara, what— what was that?"
Mara stared at her own hands, trembling. "I don't… I didn't mean to—"
"You saved us," Ten said gently.
But Sentinel Three wasn't dead.
Its limbs twitched.
Its head snapped up with a wet crack.
It began dragging itself forward again.
Mara gasped. "It's still coming—"
Evelyn grabbed her shoulder. "Sentinels don't stop unless you destroy the brainstem!"
Daniel cursed. "And how the hell are we supposed to do that?!"
Ten grabbed Daniel's sleeve. "We need to lure it to the cryo turbines! The temperature drop will slow it down!"
Before they could move, a new sound echoed overhead—
a sharp clang,
then another,
like something crawling inside the ventilation shafts.
Daniel's face drained of color.
"There's more than one."
A second inhuman shriek tore through the ceiling.
Mara's heart seized.
"Sentinel Four," Evelyn whispered. "Voss released the whole line…"
The first sentinel roared, surging back to its feet.
The second sentinel punched through the ductwork above, snarling, its jaws dripping serum.
They were surrounded.
Daniel raised his weapon even though they all knew it wouldn't help.
"Mara," he said quietly, "whatever power you used—do it again. Do more."
Mara felt the pressure in her chest tighten, heat blooming beneath her skin.
"I don't know how," she said.
"You don't have to know," Evelyn said. "Just survive."
Ten grabbed Mara's hand. "I believe in you."
The sentinels charged.
Something inside Mara broke open.
The glow burst from her skin like a storm, swirling with heat and gravity—
not light,
not energy,
but something deeper.
Something meant for war.
Something Voss didn't design at all.
She screamed—
not in fear,
but in awakening—
as the power surged outward
and the world detonated in white.
