The chapel looked abandoned until Halren touched the third pew and the floor clicked open.
A trapdoor seam appeared in the stone, narrow and clean, with no dust in the crack.
Recently used.
Vane shoved Halren forward with blade point between shoulder blades.
"You first," he said.
Halren gave a thin smile.
"I assumed you would insist."
He climbed down iron rungs into dark that smelled like wet limestone and lamp oil. Caed followed with crossbow ready. Varen went third, left hand on rung, right hand flexing against tremor he did not have time to solve.
At the bottom lay a tunnel wide enough for two people abreast, walls lined with old plague niches now repurposed as storage for ropes, lancets, and wax-sealed route packets.
Not improvised.
Industrial.
Fifty steps in, they reached a split.
Left tunnel carried child voices.
Right tunnel carried machinery noise and the low hum of bell resonance.
Varen started left.
Vane caught his sleeve.
"We need the fail-safe first."
"Children first."
"Gate reset opens an exit for all children, not only the first room."
Caed lifted her hand before either could continue.
"No argument in tunnel," she said. "We run both on sequence. Vane with Halren to fail-safe wheel. Varen with me to holding chambers. Meet at central vault in ten minutes."
Vane nodded once.
Varen hated splitting.
He hated not splitting more.
They moved.
---
The holding corridor had six cells behind iron grates and one larger room with chain benches bolted to floor.
Cell one held three boys with sedative drool on their shirts.
Cell two held two girls and a toddler curled against an older child who could not have been more than ten.
Cells three and four were empty except for torn blankets.
Cell five held chalkboard slates with names half erased.
Cell six held blood draw kits and a basket of bell tags.
Caed swore under her breath.
"They emptied some before we came down."
Varen cut cell locks in quick sequence with left-hand edge while Caed moved children into a line.
"Hands on rope," she told them. "Do not speak. If someone falls, everyone stops."
One boy stared at Varen's palm scar.
"Are you the one from the songs?"
"No songs," Varen said. "Just running."
From deeper in corridor came the creak of turning chain, then a bell strike so low it sounded like stone groaning.
Children flinched.
Varen's teeth hurt again.
The grimoire under his coat warmed against his ribs.
Caed noticed his jaw clench.
"What is it doing to you?"
"Nothing useful."
They pushed onward toward central vault.
At the junction they found the first dead guard, throat cut with narrow blade and no sign of struggle.
Caed crouched, checked pulse anyway.
"Fresh," she said. "Minutes."
"Brass Teeth?"
"Or someone he trained."
They took the left curve and walked straight into a kill box.
Crossfire from two wall slits.
First bolt took the rope in Caed's hand. Children scattered.
Second bolt hit stone by Varen's ear and sprayed chips into his cheek.
He dropped flat and threw an anchor line into the slit on the right, pulling hard. A hidden shooter slammed face-first into metal grate. Caed fired at the left slit and silenced that one too.
"Move!" she shouted.
They rushed children through the junction while Varen covered with short, ugly casts that burned his forearm.
One little girl froze at the dead guard's boots.
Caed scooped her up and kept running without breaking pace.
At central vault they nearly collided with Vane.
Good news: he had the fail-safe key wheel in his hand.
Bad news: Halren was gone.
Vane's expression said exactly what he thought of that.
"He had a tooth blade," Vane said. "Cut his own cuffs when I was opening the wheel housing. He bled himself through a maintenance hatch I was too large to follow."
Caed slammed her palm into the wall.
"He is running to Regent."
"Yes," Vane said. "And he knows our count."
Behind him, a massive bronze gear assembly ticked down from ninety.
Varen pointed.
"What is that?"
"Fail-safe delay," Vane said. "I opened outer gates, but with keyed override this countdown triggers purge protocol if not canceled at zero."
"Purge meaning?" Caed asked.
Vane did not look away from the gears.
"Flooding."
Of course.
Varen swore.
"How cancel?"
"Main bell governor room."
"Where?"
"Below us."
They all looked at each other.
Children in tow. Flood timer running. Halren loose.
No good option.
Caed made the call first.
"I take children to infirmary now. Vane, you escort half-way then return. Varen goes for governor."
Vane frowned.
"He should not go alone."
"Neither should children."
Varen decided for them.
"I go alone."
Caed grabbed his wrist.
"If you do not come back, I cannot hold moderates together."
"Then hold them anyway," he said.
He ran down the lower stair before she could answer.
---
Governor room was a circular chamber under the crypt, packed with old imperial mechanism retrofitted by fresh brass piping and blood channels. In the center hung a pendulum bell no bigger than a man's torso. Around it, twelve glass cylinders held dark red liquid, each marked with response symbols.
Varen recognized the logic immediately.
The big bell above indexed pulse timing.
This bell translated those timings into gate control and screening categories.
Children as data.
On the far catwalk stood Brass Teeth, coat dry somehow, knife in one hand and a ledger packet in the other.
"There he is," Brass Teeth said. "I was worried the bell might not reach you through all that stubborn."
Varen advanced.
"Cancel flood."
Brass Teeth tapped the ledger packet against the rail.
"Trade? You leave, I keep list, children live through dawn."
"Liar."
"True." Brass Teeth smiled. "Still worth asking."
Two more figures stepped from shadow behind him in white plague masks with red thread stitching down the mouth line.
Not dock thugs.
Choir guard.
Brass Teeth tilted his head.
"Regent says hello. Regent says you are late. Regent says you always choose one room while we move three."
Varen's right hand twitched. He ignored it.
"Where is Regent?"
"Near enough to hear your teeth grind."
Brass Teeth flicked a lever.
The pendulum bell began to swing.
First strike hit Varen like pressure behind his eyes. Not pain exactly. Direction.
Second strike aligned with his pulse.
Third strike made the grimoire pulse in answer.
Brass Teeth laughed softly.
"See? Pattern likes you."
Varen cast anchor at the lever block. Right hand failed mid-line, unraveling into a spray of blood droplets that did nothing except stain stone.
One of the masked guards lunged.
Varen switched left and caught him under the ribs with a short blood spike, not lethal, just enough to drop him. The second guard slammed a weighted chain into Varen's shoulder and drove him into the catwalk rail.
Brass Teeth backed away, still holding ledger packet.
"You are not weak," he said. "You are tuned wrong."
Varen ripped the chain free, stepped in, and drove his forehead into the second guard's mask. Bone cracked. Guard fell.
He lunged for Brass Teeth.
Brass Teeth threw the ledger packet into a brazier.
Pages caught fire instantly.
"No," Varen snapped.
He reached with left-hand pull to yank the packet clear, but the bell struck again and his cast skewed, pulling brazier itself across the floor. Burning pages sprayed into a drainage channel where water hissed and carried ash away.
Gone.
That was the mistake.
Not missing the cast.
Choosing the cast.
Brass Teeth used that beat to slash the flood lever guard chain.
Gear locks slammed somewhere above.
Countdown in Vane's chamber would not just flood anymore.
It would lock all inner doors first.
Brass Teeth saluted with bloody knife and vaulted to a side ladder.
Varen chased three steps, then stopped as a voice came through a brass speaking pipe mounted over the governor panel.
Smooth. Distorted. Neither man nor woman.
"Candidate Kross," the voice said. "You chase paper while children drown in architecture. This is why you are useful but not yet worthy."
Varen gripped the pipe hard enough to dent it.
"Regent."
"A title, yes. Keep it for now."
"Cancel the flood."
"No." The voice almost sounded amused. "Show us what you sacrifice."
The pipe hissed and went silent.
Varen slammed both palms on the governor board.
Right hand shook so hard he could not maintain fine line work.
Left hand could brute force one thing only.
He took a breath, chose ugly over perfect, and ripped the pendulum axle out with a raw anchor he could barely control.
The small bell crashed sideways and shattered three glass cylinders. Red liquid spilled across gears and shorted part of the mechanism. Flood chain stuttered.
Not stopped.
Stuttered.
Above him, heavy doors began slamming shut one by one.
Varen ran.
---
Water hit the lower corridors first, knee-high in seconds, then thigh-high where tunnels dipped.
Vane met him at the stair with two children over his shoulders and blood on his collar.
"Where is Caed?" Varen shouted.
"At junction with others. Door three sealed between us."
"Can you break it?"
"Not before water rises."
Varen swore and kicked the flooded stair rail.
From behind the sealed iron grille came Caed's voice, clear despite rushing water.
"Varen! We have nine children and one route up through ossuary shaft!"
"We have seven and main stair!"
"Then both routes. Meet infirmary."
Varen pressed his forehead to the grille for one second.
"Do not die."
Caed's answer came immediately.
"I am too angry to die today. Go."
He laughed once despite everything and hauled Vane up the main stair with the two children.
Water chased them like a living thing.
At vault level, Prell and Kesh had forced open a service hatch and were pulling soaked children through one at a time. Prell's injured leg buckled twice, but he kept hauling.
"Count!" he shouted.
"Seven with us!" Vane yelled back.
"Nine with Caed route if she clears shaft!"
They stumbled into the chapel nave as floodwater erupted from floor seams in gray fountains.
Bells above resumed, weaker but steady.
Someone had reconnected partial relay.
Outside, monastery yards were full of running figures.
Not all hostile.
Some guards were abandoning posts. Some acolytes were trying to pull children from side corridors. Others were dragging crates toward north quay.
No clean lines anymore.
Varen saw a flare launch from the quay tower.
Green-white.
Signal to move transfer team.
He started toward the tower.
Prell grabbed his arm.
"No," Prell said. "Not now. You chase that, we lose those in hand."
Varen looked from flare to children to floodwater pouring from chapel stones.
He chose the children.
Again.
Cost carved itself in him anyway.
They reached the infirmary with sixteen children.
Caed came in from the ossuary shaft route three minutes later with nine more and a broken crossbow string.
Total twenty-five rescued.
Vane checked the roll twice.
Still short.
Fen's lockhouse copy had listed fourteen names from Bellvale and four from chapel hostels. Varen spoke them under his breath while Prell checked faces in the infirmary light: Dera. Tovin. Mels. Kori. Nix. Jena. Lark. Pavo. Sarit. Hen. Vessa. Olda. Brim. Pell. And the four hostel tags with no true names, only dorm numbers.
Six answered.
Eight did not.
And those eight would vanish by sunrise if north-quay rail reached open water.
At least one transfer team had cleared north quay during flood chaos.
The plan to seize full list had failed.
The plan to stop movement tonight had failed.
They had saved who they could and lost who they could not reach.
Caed sank against the wall, soaked and shaking.
"How many are still out there?" she asked.
Nobody answered because nobody trusted their own number.
Outside, through shattered infirmary windows, they watched the green flare arc east over marsh and fade into night rain, leaving behind a thin trail that smelled of salt, burned pitch, and iron.
