Rosa found him at the new wall three days after she’d moved in.
Desmond had his palm flat on the Set Marrow, reading the note — steady now, a low hum that sang clean through the join where the wall met the old lattice deck.
The thing had cured hard as bone, ridged and strange and solid enough to lean on.
He trusted it more than he’d trusted anything he’d built with steel.
She didn’t knock.
Just stood there at the edge of the planks until he turned around.
“You said a week,” she said.
“I worked it.
The kids are warm.
Tomas stopped looking at me like I was going to rob him, and Marce let me use his good kettle.
So here’s the question I’ve got.”
He waited.
Rosa stepped closer.
Not tentative — she crossed the planks like the decision was already behind her, like turning back had stopped being an option somewhere on the pier.
“This place.
The wall, the shed, the platform that doesn’t creak the way platforms creak.
I’ve been in a hundred squats since May.
None of them felt like this.”
“It’s engineered,” Desmond said.
Flat.
True enough.
“It’s not that.” She touched the wall — just a fingertip, testing.
“It feels like it’s listening.
Like something’s holding it together that isn’t rivets.”
The warmth at his sternum pulsed.
Faint.
Covetous.
Bound her.
That one sees it.
Bind her and she holds us up.
She’s already half-ours.
Make it whole.
He didn’t answer the voice.
Didn’t answer Rosa either — just stood there running his thumb along the cured edge of the wall, trying to find words for a thing he’d never had to explain to anyone, least of all himself.
“You want to stay,” he said finally.
“I want to belong to it.” She met his eyes.
No flinch.
“There’s a difference.
Staying’s what you do when you’ve got no choice.
Belonging’s what you do when the place is worth the risk.
I’m asking which one this is.”
The Roost stirred.
Not words — just a low pull, the way the node warmed when it wanted something.
Hers.
Make her ours.
I’ll hold her.
Bind her and I stand truer.
He’d felt it before, vaguely, when the crew had moved from wary hires to something closer.
But this was sharper.
Specific.
The Roost wanted Rosa bound, not just sheltered, and it was showing him how.
A hand on the Set Marrow.
A choice spoken aloud.
The node’s confirmation.
That was all.
That was the shape of it.
“If you belong to this place,” Desmond said slowly, “it’s not just a roof.
You’d be roped to it.
What happens to the platform happens to you.
If it stands, you stand.
If it lists—”
“I was in the shelters for six weeks.
They kicked us out twice because the space was temporary and someone else’s need was bigger.
My daughter asked me every night if we’d still be there in the morning.
I can’t do temporary anymore.
I need a place that can’t be taken.”
“This place could fall.”
“Every place could fall.
That’s not the question.” She put her hand flat on the wall, palm to the ridged Marrow, and the note shifted — just a quarter-tone, warming.
She felt it.
He saw her feel it.
“The question is whether you’re building something that means to stay up.
Are you?”
The whole platform hummed.
Low.
Certain.
Waiting.
Yes.
Say yes.
She’s choosing.
Let her choose us.
He looked at Rosa — greying hair pulled back, crow’s-feet deep from squinting into too many cold mornings, hands scarred from work she’d done to keep her kids fed.
She wasn’t asking for a favour.
She was offering one.
Her belief, freely given, in exchange for a place she could defend because it was hers.
And he knew — bone-deep, the way he knew load paths — that if he said yes, if he let her bind, she’d be roped to a structure built from the dead.
A secret he hadn’t told her.
A lie she’d be standing on every day for the rest of her time here.
The warmth at his sternum spread.
He could say no.
Send her away.
Keep the crew small, keep the lie contained, keep every life at arm’s length where it couldn’t be his fault when things broke.
Or he could let her choose.
“Put your hand on the wall,” he said.
Rosa’s hand was already there.
She pressed harder, fingers spread.
“Say it out loud,” Desmond said.
“That you’re choosing this.
That you belong to the Roost.”
“The Roost?”
“The place.
That’s what it’s called.”
She nodded once.
Looked at the wall, then at him, then back at the wall.
“I choose this.
I belong to the Roost.
Me and mine.
We’re yours.”
The node flared — not heat, not pain, just a sudden bright certainty that sang up through his chest and out into the structure.
The wall hummed.
The whole platform steadied, a half-degree truer than it had been three seconds ago, and the Marrow under Rosa’s palm went warm.
She gasped.
Didn’t pull back.
Just stood there, breathing hard, hand flat on alien bone that had started to glow faintly at the edges.
Bound.
She’s bound.
She’s ours now.
OURS.
I hold her and she holds me.
One more and I stand truer still.
Get me more of these.
The light faded.
Rosa took her hand away slowly, staring at her palm like she expected to see a mark.
There wasn’t one.
But something had changed.
Desmond could feel it — a new thread, delicate and load-bearing, running from her to the structure to him.
She was part of the keel now.
If the Roost listed, she’d feel it in her bones before the instruments did.
If it fell, she’d fall with it.
And if he failed her, it would be because he’d let her bind herself to a lie.
“What was that?” Rosa’s voice shook.
Just a little.
“You’re Roostbound now.” He said it like it was a thing he’d always known, because the word had come up whole and certain from the node.
“The place knows you.
You’re not a guest anymore.”
She flexed her fingers.
Looked at the wall, then at the deck, then at the shed where her kids were sleeping.
“It feels different.
Steadier.
Like I’m standing on bedrock instead of planks.”
“You are.” He wasn’t sure if he was lying.
The platform had steadied.
She’d felt it.
He’d felt it.
The Roost purred, sated and smug, the way it had after the wall had cured.
“Will the others feel it?” Rosa asked.
“Don’t know yet.”
“Can they do it too?
Bind?”
“If they choose it.
Same as you.”
She nodded.
Stood there a moment longer, hand resting on the wall like she was testing a new weight.
Then she turned and walked back toward the shed, steady and certain, already walking the boards like she’d bought them — like the ground was hers now and no one could repossess it out from under her.
Desmond stayed at the wall.
Put his hand back on the Set Marrow and felt the note sing through him, warmer and truer than it had been an hour ago.
[The Roost] — BOUND: 1 (Rosa Iniguez, Roostbound).
She chose us.
She’ll hold the cold now.
She’s ours to keep alive.
I stand a little truer on her faith.
Lift +2 t.
Get me more of these and I fly.
One woman.
One choice.
And the whole platform had steadied on her belief.
He stood there in the cold, watching the harbour wake up grey and distant, and tried to convince himself he’d done the right thing.
She’d chosen.
Freely.
With open eyes.
He hadn’t lied to her — he just hadn’t told her the whole truth.
Heat climbed his sternum again, content and hungry.
More.
I want more.
Bind them all and I’ll hold them all.
Trust me.
I’ve never dropped what’s mine.
He didn’t answer.
Just stood there with his hand on the bone, feeling the weight of a life he’d just roped to his keel, and tried not to think about what would happen the day the truth came out and she asked him what she’d been standing on all along.
The wall held.
The platform stood.
The note sang clean.
For now, that would have to be enough.
