The warmth beneath Duskwatch’s northern boundary faded before sunrise.
By morning, only a narrow strip of thawed soil remained beside the crescent marker. It followed the old quarry path for several hundred paces and disappeared beneath ground that had shown no unusual heat the previous day.
Maelor examined the stone with three different crescent plates.
The later route markings responded weakly. Symbols cut deeper into the marker brightened for several breaths and went dark again.
Callum watched from the road.
“Can you close it?”
“I can damage it,” Maelor said. “I cannot promise where the pressure goes afterward.”
Redhaven had already shown what happened when one branch was blocked without understanding the rest of the network. Callum disliked leaving the line open. He disliked gambling with an unknown system more.
The scouts withdrew from the black-glass hill and the wyvern-cave route. They would watch from the ridges rather than camp directly above a conductor that could heat the ground without warning.
Inside Duskwatch, Elara faced a more immediate problem.
Rellan Tor’s fever had returned during the night. The bite below his knee had blackened around the edges despite repeated cleaning, and the skin above it felt cold.
Elara told him the leg had to be removed.
Rellan stared at her for a long time.
“I walked home on it.”
“You did.”
“I thought that meant it was getting better.”
“It meant you were strong enough to reach us.”
He asked for another hour.
Elara gave him enough time for Callum and Weston to speak with him, but she did not allow the operation to wait until morning.
Weston prepared the instruments himself. He worked only with visible metal pieces, checked every edge and handed them to Mara before the procedure began.
Rellan survived.
When he woke the following day, he kept looking toward the empty space beneath the blanket.
“I came back with both legs,” he said. “How did I still lose one?”
Weston sat beside the bed.
“The wound was deeper than it looked.”
Rellan turned his face toward the wall.
Several days passed before he spoke about work.
Callum offered him a position with the northern signal clerks. He could read the ridge flashes, record times and compare conflicting reports without climbing towers.
Rellan refused.
“I joined the militia to stand on the wall.”
“You cannot stand on it yet.”
“I know.”
Callum left the slate on the table beside him.
Rellan ignored it for two days. On the third, he asked one of the clerks why the western platform had flashed the wrong interval during the Redhaven retreat.
By evening, he had corrected three old signal logs and insulted the handwriting in all of them.
Duskwatch prepared around him.
Desmond returned from Kestrel Hold with the emergency authority needed to move grain, requisition carts and compensate families ordered away from the northern farms. He kept the household lists inside guarded rooms. No names appeared on public work boards after debt collectors had used his earlier records to locate vulnerable families.
Dain Marr inspected the evacuation wagons with his good arm. Each vehicle received a painted household number, a spare wheel and a driver assigned by name. Brinna organised the school groups, while older children carried blankets and water rather than running between the gates.
Grain was divided among five stores. Medical supplies were split between the treatment house, inner hall and two Iron Rams. Weston widened the inner gate lane and strengthened the shelter roofs closest to the keep.
Garen prepared the northern ground.
He shaped low terraces and broken landing surfaces rather than deep trenches. The Iron Rams retained two open road lanes, and infantry could withdraw without crossing pits of their own.
He checked every movement against Nella’s maps.
At Redhaven, grief had interfered with his earthsense badly enough for him to step onto a collapsed cellar. He no longer trusted familiarity as evidence that the ground remained unchanged.
Maevra and Elara redesigned the fire plan.
Ancient dragonfire carried too much heat for a full water curtain. Meeting it directly would create steam hot enough to blind and burn defenders. They wet roofs and wooden structures before an attack instead. Shallow channels crossed the market and inner road, allowing stored water to be released where fire began to spread.
The southern reservoir received a heavier stone cover and three outlet gates. If one failed, Elara could still reach the others.
The repaired Skybreaker stood behind the central wall.
Callum placed an empty rail and false pressure housing on the northern tower where the original weapon had killed the wyvern. From the air, the decoy looked convincing enough at a distance.
The real launcher used four smaller pressure chambers. Weston had noticed that the fourth released a fraction late during the last test. Beren believed the difference remained within ordinary tolerances.
The dragon would not offer an ordinary target.
They had four heavy bolts. Two carried hardened penetrating heads. One held a barbed head and chain. The final bolt used a broad cutter intended for a wing joint.
Nobody knew whether any of them could pierce the dragon deeply enough to matter.
The six Iron Rams returned to Duskwatch, though their cells had not fully recovered from the western campaign. Three carried full charges. Two had enough power for limited movement and one cannon shot. Iron Ram IV still mounted only two upper dart barrels after the damage at Dunmere Cut.
Callum placed Iron Rams I and II near the northern road. III covered the western gate. IV and V waited behind the inner wall. VI remained beside the treatment house for evacuation and reserve supplies.
Tobin wanted all six closer to the workshop.
Callum showed him the distance between the northern and southern gates.
Tobin stopped asking.
Scouts saw the dragon twice during the following week.
The first sighting came west of Redhaven, too far away to judge its direction. The second occurred near the northern signal line after Nella had checked the ridge that same morning.
Large claw marks appeared on bare rock. No tracks led toward or away from them.
Birds abandoned the northern trees before dawn. Cattle refused to settle in the western pens after sunset.
The dragon never entered Skybreaker range.
Weston slept in the workshop whenever exhaustion overcame him.
Elara found him there late one night with his head beside the pressure calculations.
She moved the papers before placing a bowl of stew in front of him.
“The fourth chamber still releases late,” he said.
“Tobin told me.”
“It may pull the rail during the shot.”
“Can you fix it tonight?”
“Possibly.”
“Can you test the repair before morning?”
Weston looked at the launcher diagrams.
“No.”
“Then eat and stop changing a weapon that already has a trained crew.”
He pushed the papers farther away.
Elara sat opposite him while he ate.
“I keep thinking there is another preparation I have missed,” he said.
“There is.”
Weston looked up.
“So have Callum, Garen, Maevra and I. That is why there are several of us.”
“I trust you.”
“You say that while trying to check every water gate and pressure chamber yourself.”
He reached across the table and took her hand.
Elara’s fingers closed around his.
“Let the rest of us be useful before the wall is burning,” she said.
The first warning came on the tenth morning.
The black-glass ridge flashed three rapid bursts. A second platform reported heat beneath the old excavation.
Minutes later, Nyra signalled from the northern heights.
A large shape was circling above Redhaven.
Callum moved before the next report arrived.
He took Iron Rams I and II, Garen, four shield teams and six mounted scouts toward the northern road. Nyra and Nella remained ahead of the column, watching both the sky and the warming branch.
Weston stayed at the real Skybreaker with Beren.
Orlan Pike commanded the walls. Maevra and Elara remained near the reservoir and inner-road channels.
The northern column reached the lower ridge without seeing the dragon.
Heat shimmered above the black-glass hill. Smoke rose from the cracked excavation where Perrin’s probes still remained lodged inside the conductor.
Far beyond it, a dark shape crossed under the cloud cover above Redhaven.
Garen watched the movement.
“It is turning.”
“Toward us?” Callum asked.
“I cannot tell.”
The shape disappeared behind the western shoulder of the mountain.
Garen placed one hand against the road.
The pulse beneath the hill weakened.
Another vibration travelled beneath the eastern branch toward the wyvern cave.
Callum looked from the empty sky to the warming ground.
The timing felt wrong.
He divided the force before the branch erupted.
Garen, Iron Ram I and two shield teams turned back toward Duskwatch. Callum remained with Iron Ram II and the scouts long enough to withdraw the ridge observers and confirm that nobody was trapped near the excavation.
They had covered less than a mile when the hill shifted.
Steam burst through the old cut. Hot water followed, carrying black grit and broken copper from the survey apparatus. The temporary braces held briefly before the lower shelf collapsed into the excavation.
Iron Ram II reversed from the first ground movement.
Its rear wheels reached soft mud at the edge of the road and lost traction. The crew abandoned the vehicle as the earth sank beneath its left side.
Callum’s smaller force withdrew on foot.
The eruption delayed them.
It did not remove Garen and Iron Ram I from Duskwatch’s defence.
The first southern alarm sounded while they were still on the road.
The dragon had circled behind the eastern cloud bank and followed Grayrun toward the settlement. The final river platform saw it only after it passed the ridge at low height.
Its first breath struck the canal intake.
Fire crossed the bridge, sluice frame and surrounding stone in one broad sweep. The upper gate twisted inside its housing. Water forced itself through the damaged opening until part of the intake wall collapsed into the channel.
The southern signal tower stood beside the same foundation.
Cracks travelled from the intake bridge into its lower stone. The guard completed one warning before the upper platform leaned toward the canal and fell.
The dragon climbed over the wall through smoke and spray.
Orlan ordered archers to hold until it came lower.
The first volley broke against the underside of one wing. A few arrowheads caught between scales and disappeared when the dragon banked.
Dain’s evacuation wagons were already moving from the outer streets.
The first two passed through the inner gate without trouble. The third stopped beside the pottery yard when an elderly woman named Hesta Pell refused to board.
Her grandson was missing.
Brinna’s school group had already entered the inner district, but Hesta had not seen him leave the outer street. She pushed past the driver and tried to return toward her house.
Dain blocked her with the wagon bar.
“His name?”
“Corren.”
Rellan checked the copied school register from his reinforced chair inside the signal room. Corren Pell had crossed the inner gate with Brinna six minutes earlier.
The clerk carried the slate to Hesta.
She read the name twice before allowing Dain to lift her onto the wagon.
The delay held two vehicles behind her.
The dragon’s shadow crossed the pottery road while they were still moving.
Orlan saw its head turn toward the line of carts.
“Move them through the side lane!”
The main street had been planned for evacuation. The side lane had not.
One wagon clipped a rain barrel and broke its front step. Dain and two residents lifted the wheel clear while smoke reached the roofs behind them.
The dragon released another breath toward the road.
Maevra could not stop the centre of the flame. She raised a hard current of heat along one edge, pulling part of the blast above the wagons.
The main fire struck the empty roofline beside the school hall.
Sparks crossed toward the pottery yard.
Residents opened the nearest water channel. The first gate jammed when canal grit caught beneath its wooden runner.
Elara abandoned the control lever and broke the retaining peg with a hammer. Water flooded the channel unevenly, soaking the connected eaves before the flames crossed them.
The school roof burned through in two rooms.
The firebreak between buildings kept it from reaching the family registry.
Hesta’s wagon entered the inner gate with the others.
Maevra dropped to one knee beside the wall. Her left glove had burned through along the forearm.
One of her mages pulled her into cover.
The dragon descended toward the reservoir.
Its claws struck the heavy stone lid and tore free one outer slab. The impact cracked an outlet housing and sent water across the lower road. The reservoir remained mostly intact, but Elara lost control of the eastern gate.
She redirected part of the escaping water toward the school fire.
The level dropped steadily.
Behind the central wall, Beren turned the Skybreaker.
The dragon crossed the southern marker and began climbing.
Weston watched the angle gauge.
“Wait.”
The crew held the release.
The dragon rolled toward the reservoir again, exposing the upper shoulder and wing root.
Weston called the shot.
The first three pressure chambers released together.
The fourth lagged.
The uneven force pulled the rear of the rail sideways just as the bolt left it.
The heavy projectile passed below the wing joint and struck the dragon’s upper shoulder. Its point cut across several scales, tore one loose and deflected into the field.
A narrow line of blood followed the broken scale.
Weston’s fear about the fourth chamber had been correct.
There was no time to repair it.
The dragon turned toward the flash and thunder of the launcher. It banked over the inner road and released flame across the central wall.
The breath struck more than the Skybreaker platform. Stone parapets cracked along the entire section. The launcher’s cooling pipes burst, and the outer rail bent as heated supports shifted beneath it.
One crewman died beside the release stand.
Beren and Weston survived behind the lower shield.
Three bolts remained on the loading rack.
The pressure housing below them had split around the fourth chamber.
Weston touched the visible rail.
Heat distorted the boundaries inside the connected mechanism. The charged cells remained below the platform, and he could no longer separate the damaged brackets safely.
Beren looked toward the remaining ammunition.
Weston shook his head.
“Get everyone down.”
Beren ordered the surviving crew away from the platform.
The dragon did not return for a second strike against the launcher. It crossed toward the southern canal gate, leaving part of the central parapet burning behind it.
The gate carried Grayrun beneath the outer fortification.
Garen and Weston had reinforced the arch during Duskwatch’s first months, but the water passage still required an opening beneath the wall.
Two canal workers remained inside the lower control chamber, struggling to close the emergency barrier after the intake collapsed.
Dain sent an empty evacuation wagon for them.
The dragon landed outside the southern wall.
Its weight broke the road beside the canal trench. One claw tore through the channel lining and released water into the surrounding ground.
The dragon lowered its head toward the gate.
Maevra’s remaining fire mages raised their heat breaks across the wall. Elara opened the lower reservoir outlet before the dragon’s breath could trap all the water behind the damaged gate.
Steam filled the canal road.
The workers emerged through the side passage as Dain’s wagon reached them. One walked under his own strength. The other had suffered burns across his back and neck.
They loaded him face down on the wagon boards.
The dragon breathed into the canal arch.
The outer stone endured the first heat. Iron braces inside the frame began glowing and spread the heat into connected sections of wall.
Weston reached the inner side of the gate.
He widened the visible supports into a thicker lattice, keeping his Calling away from the hidden lower mechanism. The dragon struck the outside with its shoulder.
The first impact cracked the parapet.
The second shifted the arch.
Garen arrived with Iron Ram I while the wall was already moving.
He dismounted before the vehicle stopped and placed both hands against the road.
The stone beneath the arch felt wrong.
Dragonfire had changed the outer supports into glassed material that carried heat but no longer responded like ordinary rock. Garen’s earthsense blurred around it.
He raised two columns beneath the gate.
The first found solid ground.
The second entered a softened layer below the canal lining and began sliding sideways as soon as it took weight.
“Right support is wrong!” Garen shouted.
Weston saw the column leaning.
Before Garen could lower it, the dragon struck the wall again.
The misplaced support drove against the inner edge of the arch instead of beneath it. Stone broke above Garen and showered the road.
Callum reached him from the northern lane and pulled him away as the second column collapsed.
The failure had come from the altered ground, not a lack of strength.
Garen stared at the glassed stone.
“I could not feel where it ended.”
Iron Ram III arrived from the western gate and fired its front cannon into the dragon’s chest.
The bolt shattered against overlapping scale.
Iron Ram I moved closer and fired while the dragon raised one foreleg to climb over the broken canal trench.
Its bolt entered beneath the lifted limb and lodged between two lower scales.
The dragon recoiled with a roar that shook dust from every wall.
Blood ran around the embedded iron.
Its tail crossed the road.
The strike caught Iron Ram III behind the front wheel.
The vehicle lifted onto its left side and overturned against the damaged wall. The driver’s ribs broke against the control frame. The loader struck the inner plate and lost consciousness.
The rear hatch jammed beneath the vehicle’s weight.
The upper gunner was thrown into the road and lay unmoving until two militia members dragged him behind cover.
Tobin ran toward the overturned machine.
Callum caught him.
“The cell is still charged.”
“They cannot get out.”
The crew inside hammered against the rear hatch.
Weston reached the exposed upper edge of the vehicle. He reshaped only the visible outer hinges, softening them enough for the trapped crew to force the hatch inward.
The driver crawled out holding his side. The unconscious loader had to be pulled through by his armour straps.
The cell housing had cracked but had not ruptured.
No one attempted to recover the vehicle.
The dragon tore Iron Ram I’s bolt free with its teeth.
It kept its injured side turned away from the remaining cannons as it moved toward the canal breach. Whether it understood the weapon angles or simply guarded the wound, Callum could not know.
Its next breath swept across the road in front of the Iron Rams.
Smoke and heat separated the crews.
Callum ordered the outer defenders back.
The market district had already been cleared of families. Soldiers, mechanics and fire crews still occupied the road between the canal and the inner gate.
Dain’s final wagon appeared through the smoke with the two canal workers aboard.
The burned man stopped breathing before they reached the inner wall.
Elara climbed onto the wagon, checked him and covered his face with a wet cloth.
The surviving worker tried to get down and return to the canal.
Dain held him in place with his good arm.
“There is nobody left inside.”
The man looked back at the broken gate until the wagon crossed the inner line.
Maevra’s mages burned empty awnings along the retreat path before the dragon’s flame could carry through them. Elara released the remaining street channels. Water moved beneath the smoke in shallow streams, cooling the stones enough for wounded soldiers to cross.
Desmond waited at the inner gate with the evacuation register.
Household leaders reported by group. Brinna’s school count matched Rellan’s signal-room record. Hesta Pell found her grandson inside the keep yard and struck him once on the shoulder before pulling him against her.
Two residents were still unaccounted for.
One had entered the western grain store instead of his assigned shelter to recover a locked coin box. Callum’s patrol found him coughing behind the store wall and dragged him out without the box.
The final missing name belonged to a woman who had left Duskwatch for Kestrel Hold two days earlier. Her departure had been recorded in the market ledger but not copied into the evacuation register.
Desmond crossed the name out himself.
The canal arch collapsed before the last outer soldiers reached the gate.
Stone and iron fell across the road. Water spread through the broken channel and disappeared into cracked ground outside the wall.
The dragon stepped through the breach.
Iron Ram III lay overturned beside it. The dragon placed one claw on the rear armour and pushed the ruined vehicle into the canal without examining it further.
Tobin watched the machine disappear beneath stone and muddy water.
Callum moved him toward the inner gate.
Weston remained outside long enough to touch the connected metal ties beneath the market roofs. He separated them into stone sections, breaking the routes that could carry fire from building to building.
The edge of his vision blurred before he completed the final row.
Elara caught his sleeve.
“Inside.”
The inner doors closed after them.
Heavy bars dropped into place.
The dragon entered the empty market district at a slow walk. Smoke moved around its legs. It passed the abandoned stalls and damaged workshop roofs without breathing fire again.
Callum reorganised the inner defence.
Iron Rams IV and V faced the central road. VI remained beside the treatment hall. Iron Ram I withdrew behind the second line with a damaged cannon mount. Iron Ram II was trapped near the black-glass hill under a small guard.
The Skybreaker platform could no longer fire.
The reservoir held less than a quarter of its water.
Maevra’s left arm required treatment, and two of her fire mages could barely stand. Garen could still move ordinary stone, but the burns on his palms and the glassed ground near the canal made his earthsense unreliable along the southern wall.
The dragon stopped beside the old canal road.
Maelor stood inside the gatehouse with the three crescent plates laid across a stone bench.
The western plate warmed first.
The wyvern-cave plate answered several breaths later.
The plate copied from Redhaven’s cistern stayed cold until the dragon shifted one claw onto the fitted stones above the buried canal.
A dull pulse travelled through the bench.
Garen placed his bandaged hand against the inner-gate foundation.
At first, he felt only the keep hill and the old reinforcement work he had done months earlier.
Then something answered beneath it.
A hollow space lay behind and below the keep, deeper than the storage rooms and outside every foundation line on Duskwatch’s plans.
Garen lifted his hand.
“There is a chamber under the hill.”
Maelor looked at the warmed plates.
“Was it there before?”
“I never felt it.”
Another pulse moved beneath the gate, stronger than the first.
Dust fell from the inner arch.
Outside, the dragon lowered its head toward the wall and listened.
