9:15 AM. Day 16.
No one moved.
Forty-seven people pressed against walls and huddled under blankets on frozen floors. The wind came through the stairwell shaft in slow, irregular gusts — not constant anymore, but pulsing, as if the building itself was breathing through clenched teeth.
The cold had crossed a line. Jae-min could feel it on his skin — not the gradual cooling of the last hour, but a sharper, more aggressive cold that didn't settle on the surface. It bit. His exposed neck and hands had gone from numb to burning, which meant frostbite was no longer approaching. It had arrived. His joints were stiffening at a rate his body couldn't match. His left shoulder — the relocated one — had locked into a position that was becoming permanent.
Across the corridor, the woman in the grey sweater sat where she'd stopped. Her husband had pulled the thermal blanket back over her shoulders, but her face had gone grey-white, and the skin around her lips had started to blister. Early frostnip. It would become frostburn within minutes if the temperature didn't change.
It wouldn't.
A man near the eastern wall tried to stand. His arms trembled. He got halfway up and his right knee locked — not slipped, locked. The joint had frozen in a bent position. He grabbed the wall, but his fingers couldn't grip the plaster. They'd gone past numb into something rigid, tendons too cold to flex. His hand slid. He went back down. The man beside him reached out, got his hand around the fallen man's arm, held it. Didn't pull. They both stayed on the floor, breath coming out in crystals that hung in the air for four seconds before settling like dust.
The stop was final. Not because of the order. Because the cold had made movement physically impossible for anyone who wasn't already standing, and the people who were standing were running out of standing.
"Yue."
Two seconds. Three.
"Here."
"Barrier?"
"Complete. Ten minutes ago."
She didn't need to tell him. He could feel it — the shift in air pressure beyond the south gap, the way the wind through the stairwell had changed its pattern. Something large and organized was positioned just beyond the rubble field, waiting. But it wasn't entering.
The Archbishop was patient, but he wasn't stupid. The south face was a wind tunnel pulling −70°C air through the structure at speeds that made entry hazardous even for his people. The floor was ice. The stairwells were ice. The corridors were filling with frost and crystallized breath.
The attacker couldn't attack. The defenders couldn't defend. Both sides were waiting for conditions that weren't coming.
Jennifer's voice came from the wall. Barely a voice anymore — a thread of sound, thin and strained.
"Still here. No change in formation." A pause. "I can barely maintain the link. It's static now. Shapes without edges."
Her eyes stayed closed. The veins at her temples stood out like cables. She wasn't shutting down — not yet — but she was standing at the edge of it.
Alessia hadn't moved from her position against the wall near Ji-yoo. Awake. Eyes open. But not treating, not assessing, not doing anything except sitting with her hands in her lap, conserving whatever heat and energy remained in a body that had already died once.
Ji-yoo's breathing had become something that required attention to confirm. Each inhale was shallow enough to miss. Each exhale produced less visible vapor than the last. Her face was the color of frozen linen.
Uncle sat at the center of the corridor with his rifle across his knees. Eyes moving slowly — stairwell, south windows, eastern wall, the people. Watching. Calculating. But the calculation was simpler now because there were fewer variables. Fewer options.
No paths.
Then the building shifted. Not a sound — a low, deep vibration that traveled through the floor and up through Jae-min's spine. The kind of vibration steel and concrete make when one of them decides it can no longer hold the shape it was poured into.
The east-facing wall cracked.
A single fracture from ceiling to floor, maybe two centimeters wide, leaking cold air and fine dust. The crack hit the ceiling junction and turned left, following the structural beam toward the stairwell shaft.
The wind changed. The airflow had been coming from the south — steady, horizontal, predictable. The east wall breach introduced a second source. The two streams collided in the center of the corridor, creating a vortex that pulled warmth from every surface and every body.
The temperature dropped four degrees in thirty seconds.
Yue's scanner beeped. She looked at it.
"East wall breach. Interior temperature passing minus forty."
At minus forty, exposed skin froze within minutes. At minus fifty, within seconds. The corridor was heading toward minus fifty, and the rate was accelerating.
A violent gust came through the stairwell from the east side. Ice cracked. A section of frozen plaster fell from the ceiling near the entrance and shattered on the floor. The people near the entrance flinched. The ones further away didn't react at all.
The east wall breach had done what the cold and exhaustion hadn't — it made the corridor itself the enemy. The path to the fifth floor ran through a stairwell that was now a wind tunnel fed by two separate breaches. Nowhere in this structure was the cold not reaching.
The attackers couldn't push in without risking their own people to the same conditions. The defenders couldn't move without expending heat they didn't have. The building was cracking, shifting, spilling cold air into every space it had once protected.
Neither side could continue.
Uncle's voice came from the center of the corridor. Quiet. Not a command. An acknowledgment.
"Nobody moves."
Nobody did.
The corridor held. Wind came through two breaches, met in the middle, circled, pulled, froze. Frost crept across walls, floor, ceiling. The last emergency lights flickered and died, leaving only thin grey light from the fractures.
On the other side of the south gap, the Archbishop's formation held its position.
Jae-min couldn't see them. But he could feel them — the weight of their presence, the patience of their organization, the mechanical precision of a system that had adapted to every disruption and was now waiting for conditions to change.
The battle didn't end. It just stopped.
Not because someone won. Not because someone lost. Because the cold crossed a threshold that made fighting impossible for both sides. Because the system failed, and when it did, the battle had nowhere left to go.
Jae-min closed his eyes. Wind came through the breaches. Frost crept. The people sat in the dark and breathed what air they could.
They were alive. Exposed. Barely holding.
The enemy was present. Waiting. Not defeated.
Nothing had been resolved.
