The fluorescent lights in Walmart's aisle seven buzzed overhead, filling the silence of 2 a.m. with their familiar, grating hum. It was a sound Marcus Kane had grown to despise over the past eight months. Stack. Scan. Repeat. Stack. Scan. Repeat. The routine was supposed to calm him down—that's what they told him at the VA. "Mindfulness through repetition," the therapist had said, as if he were training to become some kind of monk instead of a former combat medic reduced to stocking canned soup with a plastic name tag that read: MARCUS – HAPPY TO HELP!
He wasn't happy. And he sure as hell wasn't helping anyone by lining up cans of chicken noodle soup in the middle of the night.
He reached for another can—his third pallet of the night—and felt the now-familiar tremor ripple through his right hand. The same hand that had once held a scalpel steady while mortars screamed overhead. Now it shook while gripping soup.
His fingers tightened unconsciously. The scar across his knuckles—a souvenir from shrapnel—caught the fluorescent light. He wrapped his hand around the can a little too tightly, like he needed to prove something to himself.
He caught his reflection in the chrome of an abandoned shopping cart. Twenty-eight years old. Looked closer to forty. Dark circles hollowed out his eyes. His military-short brown hair was already graying at the temples. The Walmart vest hung loose on his six-foot frame—he'd dropped twenty pounds since leaving the service. Muscle replaced by exhaustion.
But it was his eyes that gave him away. Hazel, according to the therapist's notes. But that word meant nothing. They never stopped moving. Always scanning. Always calculating exits. Always searching for threats that weren't there.
Combat eyes.
He clenched his fist. Counted to five. Released. The tremor eased.
Four hours without an episode. That counted as progress, right?
"Hey, Kane! You planning to stock those cans or marry them?"
Marcus didn't turn around. He recognized the voice instantly—Derek. Assistant night manager. Twenty-three. Brimming with confidence that exceeded his actual authority.
Derek was everything Marcus no longer was—young, energetic, soft in all the ways life hadn't hardened yet. Clean vest. Polished name tag. Expensive cologne that tried too hard.
"Just making sure they're aligned," Marcus replied flatly, adjusting another can so the label faced perfectly forward.
Muscle memory. In another life, alignment could mean survival.
"Whatever, man. Just finish up. We got a truck coming at four."
Derek's footsteps retreated toward the electronics section, where Marcus knew he'd spend the next hour playing games on the display consoles and watching YouTube on his phone. Some people got all the luck—
The lights flickered out of sudden.
Marcus's hand flew to his hip before he even realized he'd moved. His heart rate spiked instantly. Cold sweat broke across his skin.
The lights flickered again.
The air changed and the world tilted.
Then everything went black.
Not normal darkness or power-outage darkness.
This was deeper, heavier and suffocating.
He couldn't barely see his hands in front of his face.
His breathing accelerated. Too fast. Too shallow.
"Five things you can see…" the therapist's voice echoed in his mind—Dr. Patricia Chen, fifty-something with kind eyes and infinite patience.
He couldn't see anything.
Then—
Light.
Not from above. Not even from anywhere physical.
It formed in the air itself—pale blue, cold, unnatural.
Words began to appear.

"What the—" Marcus's voice came out as a croak. He blinked hard.
The text didn't disappear.
He dropped the soup cans. The sound felt distant. Muffled.
More text appeared.

Marcus rubbed his eyes. This was it. He'd finally snapped. Eight months of night shifts and prescription cocktails and mandated therapy sessions, and his brain had finally said screw it, let's go full psychotic break. He'd wake up in a hospital bed, and the doctors'd—

Marcus stared at the floating words. For the first time in eight month his hands stopped shaking.
The blue text shimmered slightly, as if reacting to his focus.

Marcus let out a slow breath.
Hardcore mode.
Of course.
A low, grinding noise rolled through the darkness.
It wasn't coming from the ceiling or from the walls.
It sounded like reality itself was shifting—stone dragging against stone, metal tearing, something massive being forced open after centuries of stillness.
Then the system spoke again.

Good luck. You'll need it.
The text faded.
Marcus spun around, his eyes finally adjusting to the darkness.
And the world changed.
The fluorescent lights were gone.
The shelves vanished mid-row.
The smooth linoleum floor beneath his boots fractured into uneven stone.
Where aisle seven had stood seconds ago, there now stretched a massive corridor of rough-hewn granite.
The transition wasn't gradual. It was surgical. Clean edges where drywall had simply ceased to exist.
Water trickled between the stones.
The air turned damp and cold. The temperature had dropped at least thirty degrees. Marcus's breath fogged in front of him.
"Jesus Christ," Marcus breathed.
Torches flickered along walls that stretched up fifteen feet into shadows that the firelight couldn't penetrate.
Real torches, the medieval kind, pitch-soaked wood burning with greasy orange flames that spat and hissed, sending up coils of acrid black smoke that stung Marcus's eyes. The smoke smelled exactly like burning tar, catching in the back of his throat and making him want to cough.
The smell hit him next.
Damp stone. Mildew. Iron. And beneath it—
Blood.
Old blood, oxidized to brown, mixed with fresher red that was still sticky.
Marcus's senses sharpened automatically. The tremors were gone. The panic was gone. There was only assessment. Distance to nearest cover. Number of light sources. Possible ambush angles. This was familiar. Too familiar. Then—
A scream echoed down the corridor.
High-pitched. Panicked. Human.
"Marcus!"
It was Derek.
The scream cut off abruptly.
Marcus's hand went to his hip again. Still no weapon.
Another sound reached his ears. Not human. A wet, clicking noise, like something with too many joints moving through the darkness.
He grabbed a fallen torch from the wall. Not ideal, but better than nothing. The flame cast dancing shadows across the stone. Sixty feet ahead, the corridor opened into what looked like a larger chamber. Derek's scream had come from that direction.
Marcus started forward, his footsteps silent on the stone. Every nerve in his body was alive, alert, the way it used to be on patrol. The tremors were gone. The cold sweats. The intrusive thoughts. For the first time since Kandahar, Marcus Kane felt like himself again.
Even if that self was about to die in some impossible stone dungeon at two-fifteen in the morning.
He reached the edge of the chamber and pressed his back against the wall, torch held low. Slowly, he leaned out to look.
The chamber was enormous, easily the size of a basketball court, with a vaulted ceiling that disappeared into darkness. More torches lined the walls, their light revealing... things. Creatures. Marcus's brain tried to process what he was seeing and failed spectacularly.
