The second surge hit before Mara got Toma to the next landing.
Water slammed the lower rail hard enough to shake black grit from the stair joints. People screamed below. A chain post burst in blue-white sparks and threw one man backward into three others.
Mara locked her arm around Toma's ribs and kept climbing.
That was all the world was now.
Up.
Breath.
Weight.
Do not let him fall.
Rian Kest was three steps ahead, hitting panicked bodies out of the choke point before they could turn the stair into a grave. He did not move like a savior. He moved like a man too angry to let stupidity kill more people than fear already had.
"Left wall," he barked without looking back. "Keep the boy off the posts."
Mara did not answer.
She did it anyway.
Toma's throat wrap had started twitching again every time the bells screamed. The ash and salt were still there. So was the city's hunger to count him.
Another wave boomed somewhere below the houses.
Not sea on harbor stone.
Sea in streets.
"Mara," Toma said, and the fact that he could still make it sound like complaint instead of prayer nearly broke her.
"Save it."
"Mean."
"Walk."
He laughed once through his teeth, then stumbled. She took more of his weight and felt how little of him there was to take. Bone. Heat. Tremor. If she had not found him when she did, they would have been moving a body or nothing at all.
Rian glanced back at them over his shoulder.
"Bell road's open for one more turn. After that we lose the low quarter."
"And after that?" Mara snapped.
"After that the city stops pretending it knows what a street is."
Useful answer.
Not comforting.
They cut off the main stair through a narrow shrine lane where two stone saints had already lost their heads to falling masonry. Null rain streamed down the broken necks. The harbor stink climbed with them, wrong for this height.
Mara looked once over the rooftops and wished she had not.
The Ledger Moon hung lower still.
Not larger.
Closer.
The black wound in it had widened into something the eye kept trying to measure and failing. Every wet roof tile answered it. Every bell cage on the ridge line flashed at the seams like a city of coals trying not to admit it was already on fire.
Below that light, the sea moved with intention.
Not tide.
Not storm.
As if the harbor itself had been told to stand up.
"Here," Rian said.
He shoved open a warped side door and pulled them into an old bellkeeper room above the lane.
The place had once been a watch office for counting harbor fires. Now it held a cracked desk, two smashed stools, a coil of wet rope, and one lantern set low behind a stack of old tally boards.
The lantern moved.
Mara had the shard half out of her pocket before she recognized the hand holding it.
Seln stood from the far corner in a soot-dark cloak that had once been archive gray.
Toma made a sound halfway between relief and disgust.
"Of course she's here."
Mara wanted to hit her.
Wanted to ask if she had planned even this.
Wanted not to feel the ugly stab of relief at seeing a face from before the city split open.
"You knew this room?" Rian asked, not lowering his spear.
Seln's eyes flicked to the weapon, to Mara's scar, to Toma's throat wrap.
"I knew the bell road," she said. "And I knew Mara would choose height over crowd if anyone gave her a breath to think."
Mara shut the door with her heel.
"You are done speaking about me like I'm a file."
Seln took that without flinching.
"Fair."
Outside, the bells screamed again.
The whole room shuddered.
Toma's mark pulled so sharply under the wrap that he doubled over with a hiss.
Mara dropped with him at once.
"No."
Too late.
The cracked bell bracket over the door gave back a faint blue line. The iron latch answered it. Even the nails in the desk drew a thin wrong gleam toward his throat.
Rian swore, crossed the room in two steps, and yanked the bracket chain free from the wall. The bell head dropped and cracked on the floor.
The pull eased.
Not gone.
Just less.
Seln crouched opposite Mara and took one look at Toma's throat before the color left her face.
"They wrote continuity into him."
"I noticed," Mara said.
"Can you strip it?" Rian asked.
Seln gave him a flat look.
"If I could strip old harbor law off a living body in a flooded bell collapse, captain, none of us would be in this room."
That shut him up for one useful breath.
Toma leaned his head back against the wall, eyes shut.
"I would like a better room."
"You'll die in a better room too if you keep talking," Mara said.
"I know. I was trying for morale."
Her hand stayed at his shoulder until the shaking in him settled to something smaller.
Then she looked up at Seln.
"No more managing me. No more half-truths. Say the next thing whole or get out of my way."
Rian's jaw tightened at that, but he did not interrupt.
Good.
He was learning.
Seln folded herself down onto the broken floorboards like age had found her all at once in the last hour.
"Ordinary seal law is failing with the hinge," she said. "That much you have both seen. Commanded order needs stable bell rhythm, posted consequence, and a city willing to answer it. Rookfall has none of those just now."
Rian leaned one shoulder against the wall.
"Get to the useful part."
"The useful part," Seln said, "is that older harbor law was built for collapse."
Mara stared.
Seln kept going before the anger could cut across her.
"Not the public law. The one under it. Flood law. Wreck law. Fugitive law. It assumes fire, riot, broken chain posts, false orders, water in the stairs. It trusts witness and choice more than command."
Rian's expression changed at that.
Not belief.
Recognition.
"Emergency bond work," he said slowly. "Not state seal. Pre-state."
Seln nodded once.
"The city calls it obsolete because it cannot fully own it."
Mara looked between them and hated that they could speak each other's kind of sentences.
"And this helps us how?"
Seln pointed, not at Mara, but at Toma's throat.
"Because what he carries is imposed route law. What you carry is chosen old-harbor law. If you want to move him through a city whose public count is breaking, the best chance you have is not to erase the mark." She swallowed. "It is to bind him inside a stronger chosen line."
Mara thought of Gate-House Four.
Witnessed.
Uncompelled.
Descent.
No master sends me.
I go for the living.
The descent is mine.
The rings in her palm had already burned those truths into her. Maybe that was why the idea did not sound impossible.
Only dangerous.
"What does it cost?" she asked.
Seln did not lie this time.
"Intent. Witness. A named burden. And anything false in the room."
Rian gave a short, ugly laugh.
"That last one takes half the district with it."
Toma opened one eye.
"I can still leave if you'd all prefer to keep your spiritual purity."
Mara turned on him so fast he nearly smiled.
"You are not leaving anything."
"Then stop talking around me like I'm freight that learned language."
That landed.
Not only on her.
On Seln.
On Rian too.
Good.
Toma dragged himself straighter against the wall, breathing hard from the effort.
"If this is a line, make it with me in it. I'm done being moved while better people discuss my value."
There he was.
Her brother.
Frightened.
Hurting.
Still mean enough to be real.
Mara took the shard out and unwrapped it.
Its black face drank the lantern light and gave nothing back.
"Tell me how."
Seln looked to Rian.
"Do you have field oath-ink?"
He did not answer right away.
Mara saw the refusal cross his face first. Officer instinct. Keep your tools. Keep your last pieces of command. Then he reached into the inner seam of his coat and pulled out a squat brass vial and a folded strip of witness paper gone soft from rain.
"If this turns into a trap," he said, "I break the room before I let it close."
"Reasonable," Seln said.
Infuriating woman.
She took the strip, laid it on the cracked desk, and flattened it with both palms.
"Not the state form," Rian said.
"No," she said. "The older shape under it."
She turned the paper sideways.
Used the black cabinet shard to score one line down the middle.
Then she looked at Mara.
"Palm."
Mara put her marked hand over the score.
The three black half-rings heated at once.
Not enough to burn.
Enough to answer.
Seln uncorked the oath-ink vial, spilled one dark line onto the paper, then pushed the brass stylus end toward Rian.
"No one commands this. Each mouth chooses. If a line is false, the oath will fail or twist. Speak only what you can hold."
Outside, water hit stone again.
Closer.
No time for prettier ritual.
Rian set two fingers on the desk.
"Name the cause," he said.
Mara did not hesitate.
"The living leave."
The words landed in the room like iron laid flat.
Seln nodded.
"Good. Now each mouth to the cause."
Rian went first.
Of course he did.
He was either brave or too angry to wait.
"I hold this line against ordered murder until the living clear the city."
The ink moved.
A small thing.
Just enough to prove the paper had heard him.
Seln put her hand beside his.
"I witness without command, and I withhold nothing needed for the crossing."
The line on the paper darkened.
Mara felt Toma watching her.
Not as sister.
As next mouth.
She put more weight through her marked palm and said the only version that would hold.
"I take the living forward. I do not surrender them to chain, clerk, shrine, or fear."
This time the answer ran through her hand.
Heat up the wrist.
Across the scar.
Back down into the page.
Toma laughed once under his breath, weak and unbelieving.
"Show-off."
"Your turn."
He pushed himself off the wall and came to the desk like each step had to be argued through blood first. Mara moved to catch him. He shrugged her off on pride alone and planted his good hand on the paper between theirs.
His voice shook.
It did not break.
"I stand in this line alive. I do not go back to frame, route, or quiet hand."
For one terrible beat, nothing happened.
Then the cargo-continuity mark at his throat burned white under the wrap.
Mara grabbed him.
Rian caught the desk edge.
The scored line on the witness paper flashed black-silver, jumped under Toma's hand, and split into four hooked strokes joined at the center by Mara's palm mark.
The pull in the room changed.
The nails stopped leaning toward Toma.
The cracked bell bracket on the floor went still.
Even the shrieking outside seemed to shift one step farther away, as if the room had slipped under a different count.
Toma sagged.
Mara got an arm around him before he hit the desk.
"Toma."
"Still here," he muttered.
Barely.
But here.
Rian stared at the paper.
"It worked."
Seln's mouth went thin with something too close to grief for triumph.
"Yes."
Mara looked down.
Four lines.
Four mouths.
One dark center under her marked palm.
Not safety.
Not forgiveness.
Not even trust, not really.
But a thing that would hold until broken honestly.
It was more than the city had offered any of them.
Outside, the bells struck wrong again.
Inside the room, the paper answered.
Not four echoes.
Five.
The extra voice did not come from Seln.
Or Rian.
Or Toma.
It came cold and clear from the wrapped black shard against Mara's wrist and moved through the oath line like a blade finding an old seam.
"No jailer keeps this one."
