Cold. Damp. Stale air.
Ava landed with a
soft thud,
knees bending to absorb the impact.
Her hand shot out, brushing against the rough,
grimy walls.
Metal. Concrete. Corrosion.
This place wasn't just old—
it was dying.
The tunnels had been built for
maintenance crews before the collapse.
Hidden arteries beneath the bunker, snaking through the underground to service
electrical grids, WiFi nodes, and water systems.
Now?
They were a
graveyard.
Ava inhaled slowly.

She
gritted her teeth.
Lucas was getting an earful when she got out. One
wrong step
in this place and she wouldn't just be lost. She'd die.
Fried.
Crushed. Drowned.
Ava adjusted the
strap on her belt bag,
stepping carefully over a rusted pipe. The walls around her
hummed faintly
—a low, constant vibration.
The bunker's power grid was still running through here.
That meant live
cables.
That meant
danger.
She moved slow.
Precise.
Her boots barely skimmed the ground as she navigated past
exposed wires, unstable flooring, and dripping water that smelled like metal.

Ava
froze.
A soft
crackle
echoed through the tunnel—sharp, violent.
Then—
a burst of blue light.
Ava barely had time to
throw herself back
before an
overhead cable snapped, whipping down like a steel serpent.
It
hit the floor hard.
Sparks erupted,
dancing across the metal plating, hungry and erratic.
Ava's breath came fast.
That could've been
her.
[
Alternative Route Required.
]
Her jaw clenched.
She didn't have time for this.
Ava turned sharply, scanning ahead.
The tunnel
split.
Left—
the mapped path.
Longer, safer.
Right—
a dark, narrow corridor.
Ava exhaled.
Then—
she turned right.
The air grew
thicker.
Staler.
The passage was
narrower here,
forcing her to duck under hanging pipes and step over
twisted metal grates.

Ava's fingers twitched.
She didn't like
blind spots.
Didn't like
walking into places even her system couldn't read.
But
going back wasn't an option.
She adjusted her bag and moved forward,
each step careful, calculated.
The tunnel sloped
downward.
The hum of the bunker's power grid faded, replaced by
the slow, distant drip of water.
Then—
her boot hit something soft.
Ava stopped.

She inhaled through her nose,
already knowing.
A
body.
Not fresh. Not intact.
Ava crouched, eyes narrowing as she
scanned the remains.
The clothing—
scavenger gear.
The size—
a small frame. Maybe a teenager.
And the way they had
collapsed?
Like they had been running.
Ava's stomach
tightened.
She didn't move the corpse.
Didn't touch it.
But her fingers brushed the ground beside it, feeling for—
There.
Shallow scratch marks in the metal plating.
They had tried to crawl.
Tried to escape
something.
Ava exhaled.
Her system was silent.
No warnings. No threats detected.
And yet—
every instinct screamed at her to move.
She stood, boots
silent against the damp floor.
Then—
a noise.
Soft. Wet.
A slow, dragging sound.
Behind her.
Ava didn't hesitate.
She
ran.
Boots skimming the ground, breath steady, movements precise.
The tunnel was
tight, unstable, treacherous.
She dodged
low-hanging pipes, rusted support beams, jagged cracks in the flooring
that could send her
plummeting into god-knows-what.
Behind her—
That sound.
Wet. Dragging.
Closer.

Ava's chest

Something else. SHIT.
She
pivoted hard,
skidding around a corner.
Took a risk.

Ava's jaw clenched.
She pushed forward, heart hammering
but steady.
Don't stop.
Don't look back.
Then—
A sharp hiss.
So close it
prickled against her skin.
Ava's grip
tightened on her bag.
She needed a weapon.
Fast.
[
Improvised Weapon Suggestion: Conductive Shock Tool.
]
Not ideal.
But
better than nothing.
Ava
yanked
a small, modified screwdriver from her sleeve—
wired with a high-voltage capacitor.
A makeshift
shock blade.
She gritted her teeth, turning the next corner
fast—a
nd
froze.
Dead end.
A collapsed wall of concrete and steel.
[
NO EXIT DETECTED.
]
Her stomach
dropped.
Behind her—
The sound
stopped.
Ava
turned slowly.
And for the first time—
she saw it.
Crouched in the darkness,
half-hidden by shadow.
Twisted. Wrong.
A body that had once been
human.
But now?
Stretched. Warped.
Bones jutting at unnatural angles beneath sickly, mottled skin.
Its arms were
too long. Fingers too sharp.
A spine that arched like something had tried to break it in half—and failed.
And the worst part?
The face.
Or
what was left of it.
Its jaw hung loose, unhinged, like someone had
ripped it open and never let it close.
And inside—
Teeth. Too many.
The thing
twitched.
Joints cracking.
A wet,
gurgling sound
bubbling from its throat.
Ava's system
kicked in, fast.

Her
fingers tightened
on the shock tool.
No talking her way out of this.
This thing
wasn't human anymore.
It was hungry.
It took a step forward.
Ava
moved first.
She lunged, jamming the
shock blade
straight toward its chest—
The thing
reacted instantly.
Too fast.
It
twisted away,
limbs bending at angles that shouldn't be possible.
Ava barely had time to curse before
it struck.
A clawed hand
slashed toward her throat—
She
dropped low, twisting away—
The claws missed by inches,
slicing into the wall behind her.
Sparks erupted.
Ava's system
blared warnings.
[
ELECTRICAL DISCHARGE DETECTED.
]
The creature
jerked violently.
Twitching. Shuddering. Its body
convulsed—just for a second.
Ava's eyes narrowed.
Then—
She understood.
The bunker's old power grid.
The
wires.
The
exposed panels.
The
electrical surge that nearly fried her earlier.
This thing was
fast. Strong. Resistant to damage.
But
electricity?
That slowed it down.
Ava's grip tightened on the shock blade.
She looked at the flickering, half-broken power conduit behind her.
Then back at the creature.
And
smirked.
"Alright, you ugly bastard," she muttered.
"Let's see how well you fry."
