10:50 AM. Day 16.
The corridor narrowed.
They'd left the north stairwell and entered a section Jae-min didn't recognize — walls closer together, ceiling lower, debris from collapsed ductwork blocking the left side entirely. The group compressed into single file along the right wall.
The cold was different here. Stiller. The wind from the breaches didn't reach this section as directly. The air hung dead and heavy and tasted like frozen concrete — mineral and old, the way buildings smell when the warmth has been gone long enough for the bones to show.
Through a crack in the ceiling, Jae-min caught a glimpse of the snow canyon outside — ten meters of white pressing against the building's upper floors, the packed surface catching the grey light.
Rico at the front. Then the able-bodied carrying and supporting priority cases. Then the children between adults. Then Jae-min at the rear, insulated gloves on both hands, left arm stiff where the wound was exposed to the cold, right hand trailing the wall for balance.
The floor was a sheet of ice — thin enough to see concrete beneath, thick enough to make every step uncertain. Two people had already slipped. Neither fell. Both lost ten seconds catching themselves.
Yue was ahead, three bodies back from the front. She hadn't spoken since the stairwell. Both hands braced against the wall, eyes moving in a slow systematic sweep — floor, walls, ceiling, floor. The gash above her left eyebrow glistened with antiseptic beneath the frostnip crusted at the edges.
She stopped.
"Something's off" Yue breathed, flat, the word landing without inflection,
Rico paused. The line behind him compressed.
"Frost pattern. There's a section ahead where the frost is disturbed. Footprints. Recent. One person. Moving toward the north junction" Yue whispered, her voice low and precise,
The building had been evacuated. The residents were behind them. Victor was outside. The Archbishop's people were at the south gap.
Nobody should be ahead of them.
The frost didn't lie.
"Continue. Slow" Rico said, his voice calm and measured — the steadiness of a man who'd learned that panic killed faster than any threat,
The corridor turned left at a structural junction — thick concrete pillar at the center, section of intact insulation still clinging to the northern face. The spot Rico had identified as their next stop. Interior walls intact. Residual heat in the concrete.
They entered and stopped.
Someone was already there.
"An unknown. Stationary. No visible weapons. Body temperature — stable" Saem crackled, flat, the signal faint but present — the voice sealed inside his void, reading the data before Jae-min's slower mind could catch up
He stood against the north wall where the insulation blocked the worst of the draft. Arms crossed. Watching them arrive with the expression of a man who'd been waiting for something he'd expected to find.
Middle-aged. Lean. Short dark hair, grey at the temples. Narrow, weathered face — the kind that had spent time outdoors in conditions that left marks.
He wore a heavy coat that looked military but wasn't. His boots were civilian. His hands were bare.
His bare hands weren't shaking. In minus seventy, that meant something.
Rico's hand went to his sidearm. Ready. The civilians compressed behind him. Children pulled to the center.
The man's eyes moved across the group slowly — counting, assessing. He noted the injuries. The frostbitten fingers inside insulated gloves. The woman being supported.
The child being carried. The locked knee. The gash on Yue's temple. The way Alessia's hands trembled even inside the thermal fabric.
He took it all in without expression, the way a mechanic looks at an engine that's been driven too hard.
"You shouldn't be here" the man said quietly. Flat. Just fact.
Nobody responded.
"You're not from here" the man added, his tone unchanged,
A pause. His eyes went to the frost creeping along the ceiling joints.
"You're not surviving this building either" the man whispered, reading the diagnosis without emotion or cruelty,
"Who are you" Rico asked, his voice low but steady — the question of a man who preferred to talk before reaching for steel,
The man didn't answer. Instead he shifted two steps to the left — a small, casual movement into the dead zone where the draft didn't reach. He knew where the cold moved and where it didn't. That was experience, the kind you couldn't fake.
"Your group has frostbite cases, at least two mobility-limited, and one who needs proper treatment within the hour" the man stated, his gaze moving to the center of the cluster where the priority cases walked between adults
His eyes found Ji-yoo. She walked with Soulcleaver's shaft braced against her shoulder, her jaw set, her stride slow but steady. The bruise on her crown had darkened to a deep purple. Her feet inside the frozen boots moved with the mechanical determination of someone who'd decided that stopping wasn't an option.
"If you stay in this building, the frostbite cases lose their fingers first. Then the immobile ones. Then the rest" the man added, his voice unchanged,
Through the twin resonance, the thread between Ji-yoo and Jae-min pulled taut. Her heartbeat pulsed against his — slow, stubborn, refusing to stutter. The frequency was holding.
"You've been here the whole time" Rico said, his voice flat,
The man looked at the ceiling — cracked ductwork, fallen insulation, frost spreading across concrete. His expression didn't change.
"There's nothing left for you here" the man whispered quietly,
Jennifer's voice came thin from the rear, barely a whisper.
"Enemy still h-holding south. N-no push. Signal degrading. They're n-not moving" Jennifer whispered softly, the link straining her to the edge of what she could bear, gloves flexing on her hands as she forced the signal through the static,
In the background of the link, she caught a fragment — the Archbishop's voice, cold and unhurried, before static swallowed it.
"Have they moved" the Archbishop barely audible through the link's interference — patient, questioning, the tone of a man with nothing but time,
They couldn't go back. Couldn't stay. The building was failing, the cold was accelerating, and the stranger was standing in the only junction that still had insulation on the walls.
"He knows this structure. That is either a blade or a bridge," Jae-min thought, the calculation running cold and precise through a mind that had been doing this for sixteen days.
The man uncrossed his arms. Took a step toward the northern corridor.
"There's a passage through the service corridor. Connects to the north loading dock. Covered, no direct wind exposure, intact structure" the man stated, walking without looking back,
A pause. He stopped at the edge of the junction.
"It's cold. But it's not dying" the man added over his shoulder,
He kept walking. Waiting for nothing. Offering to lead no one.
Rico looked at Jae-min. The exchange lasted less than a second. The junction was filling with cold. The Archbishop was waiting at the south gap.
Through the building's bones, faint sounds carried — boots shifting on ice, the scrape of gear being adjusted. The rhythm of an army holding position with the patience of something that knew the cold would finish what it started.
"Eastern approach clear. Nothing moving" a voice from beyond the gap faint, carried through concrete and frost — the words barely reaching the junction,
The insulated gloves on Jae-min's hands weren't going to hold the frostbite back forever.
Rico released his sidearm and moved toward the northern corridor.
"Follow. Stay tight" Rico said, gruff but warm underneath,
The group moved. The stranger walked ahead, his bare hands swinging at his sides, his footsteps finding the ice-free patches on the floor without looking down. Behind him, forty-three people followed a man they didn't know through a building that was killing them.
They weren't alone in the cold. That didn't make it better.
