Two weeks after SKYHAVEN's survivors descended.
Two weeks since the plaza fell.
Two weeks, and the city had not gotten better. It had only gotten quieter in the wrong ways — the kind of quiet that meant the living were fewer, and the dead had learned the streets.
Caleb felt it before he saw it.
That was the thing about having lived in SKYHAVEN long enough — you learned the language of the city beneath your feet. The hum of the gravity generators was so constant, so woven into the architecture of daily life, that you stopped hearing it the way you stopped hearing your own heartbeat. It was simply there. It was simply true.
And then it wasn't.
The hum changed at 11:47 PM.
Hummmm—hnnn—
It was subtle. A half-step lower in frequency, a tremor in the air that Caleb registered in his chest before his brain had the language for it. He was three blocks from the eastern shelter, his earpiece crackling with his team's status reports, his dual guns holstered and his blade at his back — they'd found a family of four in the second floor of a collapsed pharmacy, the father with a broken arm, the youngest child still holding a stuffed frog that had seen better decades. They were moving. They were safe. He'd been about to radio that the sector was clear.
The hum dropped again.
KRMMMM—GRRRRNNNN—
Caleb stopped walking.
Around him, the surface of the artificial ground — the engineered substrate that kept SKYHAVEN's underside looking like solid sky to anyone below — gave a sound that had no name. Not a crack. Not a groan. Something older than those words. Something geological, like the earth itself was clearing its throat before an announcement.
He looked up.
The infrastructure tower three hundred meters north listed four degrees to the left.
creeeeaaak—
Not possible. He'd been briefed that the towers were rated for catastrophic load. He'd been briefed that the failsafes had failsafes. He'd been briefed by men who had not accounted for what two weeks of walker-dead operators and zero maintenance looked like at the structural level.
The tower listed five degrees.
KRRRRAAAK—
"All units," Caleb said into the earpiece, and his voice was absolutely level, which was the most frightening thing any of his team would later say they remembered about that night. "Evacuation. Now. Every civilian, every soldier, every body that is breathing — to the flight decks. Move."
"Colonel, what's the—"
"Move."
He was already running.
Nana was dreaming about macarons.
Specifically, she was dreaming about the little patisserie on the corner of Seventh and Linhua that had the pistachio ones with the gold leaf on top, which she had only ever eaten once but which had achieved mythological status in her memory — and dream-Nana was reaching for the last one on the display tray when someone lifted her entirely off the ground.
She made a sound like a startled seal.
"Gege—"
"Up. Now. We're leaving."
He had her over his shoulder before she'd fully processed that she was awake. The room was moving — or no, she was moving, and the room was staying, and through the window the city below Luna City looked wrong, the lights at the wrong angle, the—
"Caleb," she said, and something in her voice made him glance back at her even mid-sprint. "Caleb, the tower—"
"I know."
"Is it—"
"Don't look at it."
She looked at it.
The infrastructure tower was at fifteen degrees now, and pieces of the access walkway were falling — not fast, not dramatically, just pieces of engineered metal separating from their housing with a kind of tired inevitability, tumbling down, down, down toward Luna City below where the walkers moved in their endless directionless patterns and could not look up and could not understand what was coming.
Around them, SKYHAVEN was waking up in the worst way. Alarms. Running feet. Screaming in three different languages. A child crying somewhere behind a door. Soldiers barking orders at civilians who were too panicked to hear the words.
Caleb navigated through all of it like water finding the lowest point — certain, efficient, his grip on Nana's legs absolutely unbreakable.
"My bag," she said.
"Got it."
"The bunny—"
"Nana."
"I'm just saying—"
"It's in the bag. I checked it before I came for you."
She went quiet for exactly one second. Then: "You checked my bag before you woke me up?"
"I always check your bag."
She didn't have an answer for that. She pressed her face into his back and held on.
The flight decks were chaos organized just barely on the right side of catastrophe.
Caleb deposited her at the boarding ramp of the evacuation transport with the efficiency of a man delivering a package — both hands on her shoulders, turned her to face the aircraft, made brief eye contact with the flight officer at the top of the ramp, received a nod.
"In," he said.
"You're coming—"
"I have people still in the east sector. In."
"Caleb—"
"Nana." His voice didn't change pitch. It never did. But there was something in the way he said her name — the way he'd always said her name, since she was five years old and learning what it meant to be called by someone who meant it — that said everything he wasn't going to say. "Get on the plane."
She grabbed his face with both hands. She had to reach up to do it. She always had to reach up.
"Come back," she said.
He looked at her for exactly one second.
"I always do," he said.
She got on the plane.
He went back into the city.
Three people from the east sector. A soldier with a broken radio. The family with the stuffed frog. He moved through the tilting geometry of SKYHAVEN's infrastructure corridors with his guns drawn and his mind partitioned — work on one side, the point on the map that was Nana on the other, the gap between them simply a distance to be closed, a problem with a solution, a door with a key.
He did not think about what would happen if he ran out of time.
He found the soldier first. The family. He was reaching for the last door when the second tower went.
The sound was — there wasn't a word. It was the sound of something enormous deciding it was finished. Metal and engineered stone and a hundred years of confident infrastructure simply releasing its agreement to stay in the sky, and SKYHAVEN gave a lurch that sent Caleb into a wall, sent the family skidding, sent the stuffed frog sliding across the corridor floor.
The child dove for it.
Caleb dove for the child.
He had them all to the flight deck in four minutes. He was the last one on the transport. The ramp was closing when the western tower finally, completely, with a sound like the end of a very long argument, let go.
SKYHAVEN fell.
CRAAAAAASH—!!!
Not all at once. That would have been merciful. It fell the way certainties fall — in stages, each one worse than the last, each one giving you just enough time to understand what was happening before the next stage took something else. The gravity generators went sector by sector. The artificial ground fractured along fault lines that had never been stress-tested because no one had imagined stress like this. Buildings that had stood for a century listed and toppled and came apart at their roots.
From the transport window, Nana watched.
She had her hands pressed flat against the glass. She was not crying. She had gone somewhere past crying, into the territory where the body simply cannot process what the eyes are sending it, and all that remains is witnessing.
whshhh…
SKYHAVEN's people fell like flower petals from a tree caught in a storm. That was the thought that would stay with her afterward, that she would never say out loud to anyone, that would come back to her at three in the morning for the rest of her life: *petals.* Little lights in the dark. Some falling toward the safe zones the military had scrambled to establish. Some falling toward rooftops where they might survive. Some falling toward the streets below, where the walkers moved, and the lights went out on the way down.
WHUP—WHUP—WHUP
The transport banked south.
She pressed her forehead to the glass.
Xavier. she thought.
He had been reading comics.
This was the thing that Xavier would later find almost funny, in the dark private corner of himself where he kept the things that were too strange to say out loud: the last ordinary thing he did before the world came apart a second time was lie on his bunk in SKYHAVEN's officer quarters with a borrowed manga, three volumes in on a series he'd been meaning to start for months, and the story had just gotten good, the kind of pacing that made you turn pages faster than intended, and he had been so entirely absorbed that he didn't hear the first alarm.
He heard the second one.
WEE—OOO!!—WEE—OOO—!!
He was on his feet in one motion, blades in hand on instinct, before his conscious mind had caught up with what his body already knew. The floor was wrong. The angle of the walls was wrong. Outside the window, the city he'd grown up looking down at was at a tilt that floors should not allow.
He grabbed his pack.
He looked once at the comic, still open on the bunk, marking the page he wouldn't finish.
He went to the door.
The corridor was already chaos — people running, shouting, the building giving a shudder that sent plaster raining from the ceiling. Xavier moved against the current of screaming the way he always moved through hostile space: steady, mapped, reading the geometry. Service stairs on his left. Structural support pillar on his right. Emergency exit two hundred meters down that corridor, if the corridor held.
He made it forty meters.
The floor gave.
CRACK—!
Not the whole floor — a section of it, where the substrate had sheared along a fault he hadn't known was there, and Xavier's body processed *falling* before his mind did and he caught the pillar with one hand, the impact jarring through his shoulder, swinging out over the gap that had opened up below him. The manga was somewhere down there. The corridor was groaning. The screaming had gotten higher.
He pulled himself up.
He found the stairwell.
Around him, people were making it. Some of them were. He could hear the distant sound of transport aircraft, the military doing what the military did, and he moved through the stairwell routing the fastest path up — up, because the roof would give options, the roof would give sight lines, the roof would tell him where the aircraft were and which direction the fall would likely go.
He was thinking: *Is she already on a transport? She would be with Caleb. She would be with Caleb, which means she is already on a transport, which means she is already safe.*
*She is already safe.*
He held that thought like a rope.
He was almost to the roof when the building decided.
The structural column on the north face went first, somewhere below him, and the sound of it was something that bypassed thought entirely and went straight to a place in the nervous system that is very old, the place that understands in the body what the mind hasn't finished processing. The stairwell tilted. The walls came toward him. Xavier put his back to the reinforced inner column, wrapped his arms around a surviving support beam, tucked his chin, and held on.
The debris came down.
RUMBLE—!
CRASH—!
He was aware of pain. He catalogued it the way he catalogued everything — methodically, without panic, while the building fell around him and the screaming became very loud and then, in stages, became quieter. Something hit his left side. Something hit his head. His vision went white for a moment, then gray, then came back.
Dust.
Silence, or what passed for silence when you were still in the process of understanding whether you were alive.
He was alive. He catalogued this also.
His blades were still in his hands. He didn't remember maintaining his grip but here they were, here he was, upright against the column he'd wrapped himself around, in a space that had collapsed to approximately two meters of viable clearance. His ribs informed him of the situation on his left side. His head offered its own complaint. His left hand, when he looked at it, was bleeding from three knuckles.
Acceptable.
He found the path upward through the debris because there was always a path, if you looked correctly and did not panic. He moved through it slowly, conserving, assessing each handhold before committing weight. Once a section of ceiling shifted when he touched it and he froze and breathed through his nose until it settled. Twice he found people who hadn't made it, and he looked at them long enough to be certain, and then he looked away and kept moving.
The roof.
The night sky.
SKYHAVEN was still falling around him — not where he was, not exactly, but sectors of it were still in the process of completing their descent, the sounds of impact rolling up from below in waves. Luna City's lights were wrong from this angle. Everything was wrong from this angle.
He stood on the roof of a building that had settled at a seven-degree lean, on an island of surviving structure surrounded by the wreckage of everything that had been his city for two weeks, and he looked out at the dark, and he breathed.
Somewhere below him, the walkers would already be moving toward the sound.
"Hhhrk...gghhk..."
Somewhere below him was Luna City, and the outbreak, and everything they'd been surviving.
Somewhere below him was Nana.
*She is already safe*, he told himself. *She was with Caleb. She is already safe.*
He looked out at the dark and he breathed.
*I will find her.*
His left hand had stopped bleeding. His ribs complained with each inhale.
He looked at the blades in his hands — still clean, the steel still picking up what remained of the light, the weight of them exactly right in his palms. Familiar. Certain. The one constant in any geometry.
He looked out at the fallen city.
He thought about her laugh. The specific frequency of it. The way it caught him off guard every time, even now, even after everything — the way it sounded like it couldn't help itself.
Below him, SKYHAVEN's wreckage settled into its new shape.
The walkers were already moving.
Xavier Shen, S-Class, stood on a listing rooftop at the edge of the fallen sky, and thought: *first, survive the night.*
And then his legs gave out from under him, quietly, without drama.
THUD!.
And then the dark came, and took him.
