Desmond planted both boots on the south platform’s ragged edge, looked down at what the collapse had left of a week’s work, and made his decision before he’d finished looking.
“Right,” he said.
“We’re doing it again.”
Marce, wringing harbor out of his coat, stopped mid-twist.
“Doing what again?”
“The wall.
The brace.
All of it.” He turned.
The crew stood near the shed, soaked through, watching him like men who hadn’t decided if their foreman was brilliant or mad.
“Properly this time.
Slow.”
Tomas frowned.
“Des, it’s past six.
The barge inspection’s at dawn.”
“Then we work through the night.”
Nobody moved.
“I rushed it,” he said.
“Didn’t give the Marrow time to set, and it snapped like glass.
That’s on me.
But the fix is real.
I just have to do it right.” His eyes found Marce.
“You said it sets slow or it sets wrong.
So we set it slow.”
Marce stared at him.
Then, slowly, he uncrossed his arms.
“How slow?”
“Hours.
All night if that’s what it takes.”
“And if it doesn’t hold by dawn?”
Desmond met his eyes.
“It will.”
The warmth at his sternum pulsed once, approving.
They cleared the south platform first.
Everything that wasn’t structural got moved — tools, tarps, the bent rebar Tomas had been using as a pry bar.
Desmond walked the edge, palm flat against the surviving piles, feeling for the note.
Faint and steady — the low dry hum of Set Marrow under no strain.
The platform held.
Barely.
The north side was a ragged wound of splintered timber and empty air.
He knelt where old wood met the first rib he’d Set two days ago — back when he still thought he knew what he was doing — and pressed both palms flat.
The voice came up through his hands like heat through stone.
You’ll do it right this time.
“Yes.”
Slow.
I’ll tell you when it’s ready.
“I know.”
Good.
Then feed me and I’ll grow you something that holds.
He reached into the canvas bag at his feet and pulled out the first piece of raw Marrow — forearm-length, ridged, faintly warm, still carrying the mineral smell of the Leviathan’s dead core.
Struck flint over cold marrow-fat.
He set it against the existing rib, felt the node flare hot, and pushed.
The Marrow didn’t snap into place.
It grew.
Like coral in cold water, the new piece fused to the old, the join spreading in hairline branches that thickened and locked into one continuous lattice.
He felt it in his teeth, his chest, the palms of his hands — the hum rising to meet the new growth, accepting it.
It took four minutes.
When it was done, warmth had spread down his ribs and his hands were shaking.
“Bloody hell,” Bram said from somewhere behind him.
He sat back on his heels, breathing hard.
The join was seamless.
And the note — the dry bone-hum of the platform — had deepened, like an instrument gaining a string.
The crew was staring.
“That’s one rib,” he said.
“We need forty more.
Tomas, hand me the pieces.
Bram, you’re going to learn this.
Marce—”
“And I’ll tell you if you’re rushing.”
“Fair enough.”
He reached for the next piece.
By midnight, the wall was halfway up.
He’d stopped counting ribs.
His hands had gone numb an hour ago and the warmth at his sternum had become a constant grinding ache — a coal burning too hot for too long.
The node felt bruised under his skin.
Cold, tired, every breath tasting like metal, but the wall was growing, rib by rib, and the crew had stopped talking and started watching like men in a church.
Bram knelt beside him, hands hovering over the newest join, feeling the hum.
“Can you hear it?” he asked.
“Not hear.
Feel.
It’s like — like a drum.
But in my teeth.”
“That’s the note.
When it’s steady, the structure’s holding.
When it goes flat, something’s wrong.”
“And when it’s growing?”
“It rises.
Just a bit.
Like it’s pleased.”
Bram glanced at him.
“Pleased.”
No answer.
He pressed the next piece into place, felt the node flare, and pushed.
The lattice spread.
The hum rose.
And somewhere deep in his chest, behind the ache, the voice purred.
Yes.
Like that.
Slow and strong.
I can work with slow and strong.
Low and satisfied and almost warm — something in his spine unclenched, a tension he’d carried since the node bonded.
The Roost wasn’t hungry.
Wasn’t pressing.
Just…
pleased with him.
With how he was feeding it.
And God help him, that felt good.
Another rib.
Then another.
The wall climbed.
By two in the morning, Marce handed him a tin cup of something hot that wasn’t quite tea and dropped onto an upturned crate.
“It’s working,” Marce said.
“Working.” His voice came out hoarse.
“You look like hell.”
“I’ll live.”
Marce sipped, eyes on the wall.
Taller than a man now — a sweeping curve of Marrow that followed the pier’s load-path like something had poured it there, something that understood where the weight wanted to go.
Under the work lamps it looked like bone.
A rib cage holding up the platform’s chest.
“This isn’t welding,” Marce said.
Silence.
“I don’t know what it is.
But it isn’t welding.”
“No.”
Marce’s gaze settled on him, steady.
“Are you going to tell me what it is?”
The Leviathan’s corpse under the harbor.
The rawness in his own chest, the price of every rib.
The lie he was already too deep into to climb out of.
“Not yet.”
Marce was quiet a moment.
“But you will.”
“When I can.”
“Right.” Marce stood, drained the cup, held out his hand.
“Give me the next piece.
You’re shaking too hard to hold it straight.”
He handed it over.
The lattice grew.
The note rose.
Marce, feeling it happen under his own skin, went very still.
“Christ,” he whispered.
“Welcome to the church,” Bram said from the shadows, and someone laughed, short and half-mad, the sound of men who’d stopped sleeping two days ago and started believing in something they couldn’t name.
He reached for the next rib.
The barge inspector arrived at six-fifteen, just as the sky was going grey.
Slumped against the shed wall, too tired to stand, he watched Tomas and Bram guide the man along the platform.
The wall was done.
Forty-three ribs of Set Marrow, cured slow and locked strong, curving along the pier’s south edge like a spine holding the whole structure upright.
Beautiful.
Impossible.
And if the inspector looked too close, enough to get them all arrested.
The man stopped in front of the wall, frowning.
Older, grey-haired, ink-stained hands — someone who spent more time with clipboards than salvage.
He knocked his knuckles against one of the ribs.
The note rang, low and pure.
“Welded?” he asked.
“Welded,” Tomas said, smooth as silk.
“Salvage steel.
Des did the joins himself.”
Another knock, harder.
The note held.
He stepped back, marked his clipboard, shook his head.
“Twenty years inspecting waterfront work.
Never seen a weld that clean.”
“Des is particular,” Tomas said.
The man grunted.
Walked the length of the wall, testing joints, checking the load-path, and stopped in front of Desmond.
“You do this in one night?”
A nod.
He didn’t trust his voice.
“Hell of a thing.” Another mark.
“Passes.
Don’t let me catch you cutting corners next time.”
Gone.
Eyes closed, head tipped back against the shed wall.
His chest ached.
Hands bruised.
The node still hot — a coal that wouldn’t bank — and the exhaustion behind his ribs felt like it went down to bone.
But the wall was up.
The crew had seen it rise.
And the Roost, sated and content since it bonded — truly content, not just quiet — was showing him something.
Not words.
A vision.
The pier, whole.
Platforms raised and joined, Marrow-laced and strong, rooms built into the bones, a place with walls and a roof and people safe underneath.
The Hatchery at the center, pulsing warm.
Harbor below.
Sky above.
A city small enough to hold in his mind and vast enough to matter.
This, the voice said, low and satisfied.
Feed me slow and I’ll grow you this.
His eyes opened.
The crew still stood on the platform, staring at the wall like they’d never seen steel before.
Marce at the pier’s edge, one hand flat against a rib, feeling the note.
Bram on a crate, grinning like a fool.
Hollowed and aching, still riding the high of the Roost’s purring contentment, he looked at what he’d grown by hand and thought: yes.
God help me.
I want that.
[The Roost] — FIELD-SET: COMPLETE.
Wall cured, load stable, structure holding.
You did it right.
Slow.
I can work with this.
Feed me more and I grow you rooms.
I want the whole pier.
Give me this and I grow you a home.
