The shouting in the corridor started before Kai moved away from the door.
Someone on the floor above was calling for a child. A door slammed hard enough to shake the wall. Boots hammered down the metal stairs outside in fast, uneven waves. The apartment, which had felt small only a minute ago, now felt like a box waiting to be buried.
The weak red emergency strips along the wall gave the room an ugly color. Under that light, Liora looked even more tired than she had before. The warmth of the morning was gone from her face.
Another heavy impact rolled through the district. A burst of screams came from the street below.
Kai kept his place in front of the door. "You are not going alone."
Liora held his gaze for a second. Her face did not soften, but her answer changed. "Then stop blocking the door. If we stay here, we lose time."
That was enough for him.
Kai stepped aside, pulled on his jacket, grabbed the small tool pouch from the shelf, and took the narrow utility knife from beside the sink. It would not help much against a beast, but empty hands felt worse. Liora saw what he took and said nothing.
When he opened the apartment door, the hallway was already full.
People were rushing toward the stairwell at the end of the corridor, some carrying bags, some still in sleep clothes, some with nothing at all. An old man from the next unit was trying to drag a broken cart behind him. A woman from the floor below was holding two children so tightly that one of them could barely breathe.
The speaker overhead crackled, then died again before any words came through.
Liora moved first. Kai stayed close beside her as they joined the flow of bodies.
The stairwell was worse than the hallway. Every landing was crowded. People pushed down three steps, stopped when the level below clogged, then pushed again. Somebody had dropped a bag of canned food, and the loose tins rolled under boots. Children were crying. The smell of sweat and hot wiring filled the air.
Kai took one look at the center of the stairwell and knew it could turn deadly.
He leaned closer to Liora. "Too tight. If someone falls, this becomes a trap."
She looked down the stairs, then toward a narrow maintenance ladder shaft behind a locked mesh gate on the side wall.
Kai understood at once.
"That lock is old," he said.
"Good."
He moved before anyone around them noticed. The gate had a cheap side housing and a manual override plate. Kai dropped to one knee, forced the cover loose with a pry tool from his pouch, and slipped his fingers inside. The building shook again while he worked, but the old lock gave way after a few seconds.
The gate clicked open.
Kai pulled it wide and pointed the woman with the two children inside. "Maintenance stairs. Move."
She stared at him for half a heartbeat, then dragged the children through. The old man abandoned his cart and followed. Three more neighbors squeezed in after them before the crowd in the main stairwell noticed. By then Kai and Liora were already through, and he had pulled the gate mostly shut behind them.
The maintenance stairs were narrow, steep, and badly lit, but they were still better than being trapped in a crush of bodies.
They went down fast.
The sounds of the breach followed them through the walls. Impacts. Sirens. A deep roaring sound that did not belong anywhere near a city. On the sixth-floor landing, one of the children slipped. Kai caught him by the jacket and pushed him back toward his mother without breaking stride.
By the time they reached the ground level, everyone was breathing hard.
The shaft opened into a service corridor behind the main lobby.
The lobby itself had already fallen apart. Residents from the lower floors were flooding toward the front exit while two building workers shouted different orders that nobody followed. Through the cracked glass panels, Kai could see the street outside. Smoke was rising beyond the next block. A transport van lay at an angle near the curb. People were still running, but not like an evacuation. It looked like panic.
Then a body struck the front glass.
The sound froze half the room.
It was a man in district transit colors. Blood covered one side of his chest. He hit the panel, slid down it, and disappeared from sight.
Something moved in the smoke outside.
Long limbs. Pale hide. A body built wrong.
The front glass exploded inward.
People screamed and threw themselves aside. The creature came through the broken entrance in a blur of impact and weight, knocking one of the building workers into the wall hard enough to drop him at once. Its forelimbs were too long, its mouth too wide, and its movement too fast to feel natural.
Kai grabbed the nearest metal stand and drove it sideways into the beast as it turned toward the crowd. The blow did not hurt it, but it changed its line. That gave Liora enough time to drag an injured resident away while the others stumbled toward the side corridor.
"Back way," Kai shouted. "Now."
This time people listened.
Kai backed toward the service corridor, keeping the twisted stand between himself and the beast. It struck the metal once and tore half the frame off. Then it lunged again and caught a hanging cable in the broken wall. Blue sparks flashed across its shoulder. The beast screamed and recoiled, and Kai slammed the emergency side door control with his elbow.
The reinforced panel dropped halfway, struck debris, and jammed.
It would not hold for long, but it would slow the beast.
Kai ran after Liora into the corridor.
There were nine of them now. Kai and Liora. The mother and her two children. The old man from the upper floor. A maintenance worker with a broken wrist. A delivery driver with blood on his sleeve. And a teenage girl so pale she looked ready to faint.
The corridor was narrow, concrete-walled, and lined with old pipes. Behind them, metal shrieked as the jammed door started to fail.
Liora reached the maintenance worker first and checked his arm while moving. "Can you walk?"
He nodded too fast. "I think so."
"Then keep moving."
Kai looked ahead. The corridor led toward a junction connected to the district tram access and freight tunnels. He knew the rough layout from repair jobs. If the breach was already on the streets, the main exits would be death.
The corridor bent left.
Gunfire rattled somewhere above them. A heavier defense cannon answered in the distance. For a moment Kai felt something close to relief. The city was fighting back.
That feeling died when another announcement echoed through a speaker in the ceiling.
"Outer transit access compromised. Civilian reroute in effect. Proceed to secondary evacuation channels."
No map appeared. No arrows changed. Nothing in the corridor told them where those channels were.
They reached the junction and stopped.
The main tram corridor ahead was blocked by a collapsed support beam. To the right, the freight line security shutters had dropped completely. To the left, an old emergency transit passage was still open by less than a meter.
Kai saw the route marker on the wall and understood where it led.
"Utility transfer corridor," he said. "It reconnects with the lower tram lane."
The delivery driver looked at him. "You sound very sure."
"I repaired signal relays down here last winter."
"Will it hold?"
Kai looked at the cracked ceiling and the rust around the support bolts. "Not forever."
Another crash came from behind them, much closer now. The beast had broken through the side door or found another way into the service line.
That ended the discussion.
Kai sent the mother and children through first, then the injured worker and the old man. Liora followed with the teenage girl, guiding her by the shoulder. Kai stayed behind only long enough to grab a fallen maintenance rod from the floor before entering the transfer corridor himself.
He pulled the emergency lever beside the frame. The old gate behind them shuddered downward with painful slowness.
Halfway closed, it stopped.
Then a pale arm slammed into the narrowing gap from the other side.
The whole gate buckled inward.
The mother cried out. The children began screaming again.
Kai reached the lever housing at once and ripped off the cover plate with the rod. The backup motor was dead. The gate had dropped on old spring tension, and now something stronger was forcing it back up.
He jammed the rod into the lower brace and the exposed gear housing.
The mechanism shrieked.
The arm drove forward again.
This time the rod bent, but the gear teeth caught hard enough to hold for one more moment.
"Move," Kai said. "All of you. Run."
Nobody argued.
They ran deeper into the corridor while the gate screamed behind them under repeated blows.
Kai retreated last, stepping backward until he was sure the others had gained distance. Liora had not gone far. She stood ahead with one hand on the teenage girl's shoulder, waiting for him.
He ran to her, and together they pushed farther down the transfer line.
The passage narrowed, then opened into a wider maintenance tube with exposed wiring along one wall and old inspection windows on the other. Through the dusty glass, Kai could see part of the lower tram lane. A few civilians were running along the platform beyond.
The next problem was waiting for them.
The access door connecting the maintenance tube to the platform had sealed automatically.
An emergency terminal beside it flashed red.
ROUTE LOCKDOWN
LOCAL AUTHORIZATION REQUIRED
Kai swore under his breath.
The children were crying harder now. The maintenance worker was shaking with pain. Somewhere behind them, the blocked gate gave a long tearing sound.
Liora looked at the sealed door, then at Kai. "Can you open it?"
He was already moving toward the terminal. "Maybe."
The panel was old district hardware. That was the only reason he had a chance.
Kai tore off the lower cover and exposed the wire cluster inside. Lock feed. Alarm loop. Manual override. The labels were half burned away, but the layout was still familiar enough for him to read.
Behind them, metal screamed again.
Kai forced himself to breathe evenly and crossed the override line with the damaged power feed.
Sparks jumped.
The terminal went dark.
For one terrible second, nothing happened.
Then the sealed door jolted and began to slide open.
Cold air rushed in from the tram lane.
Relief hit the group so sharply that one of the children started crying even harder.
Kai did not trust it.
He looked through the widening gap and saw the lower platform clearly for the first time. The lane lights were failing in sections. A few civilians were pounding on the locked door of an idle service tram. One side of the platform wall had collapsed, leaving a break full of dust, cable, and darkness.
And at the far end of the lane, something moved.
Not one shape.
Several.
Kai felt the cold drop through his chest.
The breach was already below ground.
The gate behind them exploded inward.
The sound cracked through the tunnel like a shot.
Kai shoved the nearest civilians through the opening to the platform as a pale shape burst into the maintenance tube behind them.
The path ahead was open.
The safe route was gone.
