A black-silver line cut across the saint's face.
Mara spun.
It had not been there a breath ago.
Now it ran from the top of the wall carving to the floor drain in a blade-thin stroke, dark at the center and pale at the edges, like moonlight trying to remember how to be a wound.
The lower bell rang once.
The line brightened.
Not enough to light the room.
Enough to make the witness-hand on the service drawer shine wet-white through its black wax marks.
Ledger light.
Mara was already moving.
The bell-metal strip came out of her sleeve. The words on it had not changed.
Witness, blood, moon.
The route had opened the last part for her.
"Good," she said, too breathless to mean it.
The light did not stay still. It trembled across the stone as if whatever slit it came through was not fully open yet.
Mara looked up.
Above the saint's rubbed-flat head ran a seam so fine she had missed it the first time through. Not a crack. A shutter line. The kind a maintenance hand would build if they needed moon pressure in a room nobody respectable should know existed.
The moon-salt cloth.
She snatched it from the drawer and climbed the chain block to reach the carving. The room tilted on her halfway up. Fever. Blood loss. Too much pressure too fast. She grabbed a hook, steadied herself, and kept climbing.
The cloth was stiff with age until the Ledger light touched it.
Then it went soft.
Not with rot.
With use.
Mara pressed it into the seam above the saint's head and felt a metal catch give under the salt crust.
There.
She hooked two fingers into the gap and dragged.
The shutter shrieked open by an inch.
Ledger light poured through.
It hit the saint image full in the face and turned the room wrong.
The black stone floor took the light and held it under the surface like deep water.
The hooks on the wall stretched long shadows that looked too much like hanging bodies.
The witness-hand began to sweat clear beads from old cut lines that had no business holding moisture anymore.
And Mara's mark opened under her shirt like a mouth trying not to scream.
She nearly dropped off the chain block.
The shard answered with one hard pulse in her hand.
Not warning.
Aim.
Down.
Mara jumped back to the floor and landed badly enough to jar her teeth.
The beam ran straight over the drain and stopped at the chain ring.
That was the working point.
Of course it was.
Everything in these rooms came back to bracing, holding, witnessing, and moving the helpless somewhere worse.
She picked up the witness-hand again.
The dead calm in it flowed up her fingers at once.
Not enough to blank her out this time.
Enough to take the edge off the hunger clawing at her mark.
Useful.
Disgusting.
She set the hand in the chain ring.
It fit too neatly.
The finger stumps locked into grooves inside the metal as if the ring had been cast for it.
Mara did not want to think about that.
She laid the shard across the palm.
The black shine took the Ledger light and turned it inward.
Still nothing else happened.
All right.
Blood.
She held out her right hand over the witness-hand and squeezed her reopened palm wound.
Three drops fell.
They hit the preserved skin.
Sank.
Waited.
Then slid off and ran useless into the chain block.
Mara stared.
"No."
The room stayed dead.
Not dead exactly.
Refusing.
She looked at the strip again.
Prime witness by line blood.
Not just blood.
Line blood.
Her palm was hers.
But it was labor blood. Gate blood. Running blood.
Not the line.
The line sat higher.
The seam over her sternum had gone from hot to aching cold under the Ledger light. Like the wound in the moon had found its echo in her body and was waiting for her to decide whether she meant anything she had done so far.
Mara laughed once.
Short.
Mean.
"So that's the rule, then."
Not accident.
Not inheritance happening to her while she flinched and bled and tried to keep up.
Choice.
Take it or stay ordinary and lose him.
Simple enough to be cruel. Which meant it was probably true.
She put the strip between her teeth and shoved two fingers under her collar. The mark had swollen into a hard burning ridge under the cloth. Touching it made her breath hitch.
No knife.
No clean tool.
The shard edge would do.
She dragged it out of the witness-hand, braced the dead palm against the chain block, and pressed the lower corner of the shard to the seam over her sternum.
For one second she did nothing.
That second mattered.
The room waited.
The moonlight waited.
Mara thought of Toma gagged on a sledge while some bored official timed his fear against her future.
Then she pushed.
Pain tore white through her chest.
Not skin pain.
Not cut-hand pain.
Deeper.
Like slicing through a scar that had never stopped being made.
Blood ran hot down her ribs.
The mark answered all at once.
The chain ring slammed tight around the witness-hand.
The shard darkened until the Ledger light disappeared inside it.
And the room inhaled so hard the shutter above screamed wider on its own.
Moonlight struck her full in the chest wound.
Mara made a noise she would never admit to later.
The strip fell from her mouth to the floor.
The witness-hand clenched.
Not living movement.
Mechanism.
Still enough to make her flinch.
Then the calm hit again, stronger than before.
This time it did not numb her.
It pinned her.
Pinned her anger. Pinned her fear. Pinned the animal part that wanted to curl around the wound and stop.
It left one thing free.
Intention.
That was worse.
It meant the room wanted her conscious for the choice.
Mara leaned over the chain block, blood dripping from the cut seam onto the witness-hand, and whispered through clenched teeth, "Show me."
Nothing.
Then she understood the missing piece.
Witness.
Not only the dead hand.
Her.
This path did not want her as cargo.
It wanted consent.
Chosen cost.
Fine.
She straightened as much as the pain allowed and spoke into the room like she was filing a grievance that might bite back.
"I pay this for my brother."
The shard flashed.
The chain ring answered.
And the world folded.
No corridor.
No room.
No body for one violent instant.
Only a line pulled through light.
Mara dropped into it hard enough to lose a breath.
Stone flew past beneath her feet without her moving.
Bell ribs.
Drain channels.
Bone braces packed into civic foundations.
The hidden underworks of Rookfall unzipped under the pressure of the Ledger Moon like a wound forced open for inspection.
Then the line caught.
Fifth Stair.
Below it, not above.
The sight locked there.
Mara saw the underside of the harbor terraces through moon-silver grates and wet iron beams. Water slapped black stone somewhere off to the left. Boots hammered along a maintenance shelf too narrow for public use.
Four men.
Just like the imprint.
One with a chain in hand.
One pushing the sledge.
One clerk-thin and sour around the mouth, carrying a shutter lamp hooded down to a slit.
And Toma in the middle, wrists bound, jaw bruised dark where the gag had been yanked too tight.
Alive.
Still alive.
He stumbled once.
The chain-man jerked him upright before he could fall.
The official voice from the ring came back at once, now wearing a body.
Gray coat.
Quiet Chain stitch at the inner cuff.
Not high rank.
High enough.
"Keep him moving," the man said. "If the moon shaft is full when we get there, I will start taking fingers from the slower one."
The clerk-thin man swallowed.
"There are already people at Fifth Stair. Wardens. Terrace sweep."
"Then they can do their jobs and look outward."
The sledge runner scraped sparks off stone.
Toma turned his head.
Not toward them.
Toward something ahead.
Mara followed his line and saw it.
The shaft.
A vertical cut through the underworks where Ledger light poured down in one black-silver column thick enough to drown in. Not natural. Not an ordinary vent. A ritual throat dropping from somewhere under the Fifth Stair bells straight into the buried route.
Chains hung through it.
Hooks.
Winch braces.
And on the wall beside it, written in fast maintenance hand:
moon reception
Mara's whole body tried to move toward him and could not.
Sight only.
Witness only.
That was the cost too.
To see and not touch.
Toma stumbled again, but this time he twisted as he did it. Deliberate. His shoulder slammed the clerk-thin man into the wall hard enough to make the hooded lamp jump.
Good.
That was her brother.
Even bound and bruised, even dragged through a hole in the city's throat, he still knew how to make somebody else's night worse.
The chain-man cuffed him across the back of the head.
Mara lunged.
The sight did not care.
Pain tore through the cut in her chest so hard the underworks went white around the edges.
The official turned his face half toward her line of view then, not because he could see her, but because the method had carried enough of her rage to shake the witness.
Sharp nose.
Split lip gone white with old scar tissue.
One finger on his left hand missing to the middle joint.
Not the clerk.
Not the chain-man.
The handler.
The handprint at the door.
He looked at the shaft and said, almost bored:
"Hurry. The girl's line is already climbing."
The sight broke.
Mara slammed back into herself on her knees beside the chain block.
The witness-hand dropped open.
The shard spat black light once and went dead-heavy in her grip.
Blood hit the floor in bright drops she could actually see now.
Her own.
Too much of it.
She caught herself before her face met the stone and stayed there, one hand clamped over the cut seam, breath sawing in and out.
The room had gone dim again. The shutter above was already dragging itself shut a thumb-width at a time.
Moon window closing.
Method spent.
Worth it.
More than worth it.
She knew where he was.
Under Fifth Stair.
Alive.
Still moving.
And whatever waited at the moon shaft had been prepared for her long before she knew the city was hunting her.
Mara looked up through the last black-silver line crossing the saint's ruined face.
The room gave her nothing else.
No mercy.
No comfort.
Just the fading afterimage of Toma being marched under the Fifth Stair in a flash of moonlight no ordinary mortal was ever meant to see.
