The first tone sounded behind us.
It came through the stone rather than the air, a low note that settled in my ribs. Ahead, the gallery narrowed between the turning brasswork and a wall carved with shallow handholds. Beyond it waited a round brass threshold, its outer ring turning by fractions while white light shone through the seams.
Jak crouched beside the nearest band of moving light. He kept one hand near his crossbow without touching it, eyes flicking from the floor to the balconies behind us and back again. “Three bands,” he said. “They cross at the brasswork. The left opens first, then the middle. We have time for two bodies before the next note, perhaps three if nobody drags a foot.”
“I’ve never dragged anything in my life,” I whispered.
Jak glanced at my boots. “You’re carrying the marker.”
“Then I’ve never dragged anything while carrying a marker.”
Elowen didn’t look up from the floor. “Save your breath. Step where I step.”
One sleeve had slipped back, showing the thin strength in her wrist as she held the sun disk over the first crossing. Gold gathered around its rim, not bright enough to blind, only enough to show where the stone dipped and where a hairline seam waited beneath the dust.
“There,” she said. “The pale strip is safe. The darker one will lift your left foot. Don’t test it.”
That last part was aimed at me with the calm certainty of someone who had met me before. She had good reason. I’d made an entire career of discovering which warnings were meant personally.
Isolde stood at the gallery’s edge, tall and still, one hand raised toward the turning brass. Her dark fitted leathers caught the white light along her waist and the long strength of her legs. I wanted her. The floor still meant to throw me into a wall. Both facts remained true as pressure rippled through the air.
“The brasswork is drawing from the threshold,” she said. “Not power exactly. Weight. The nearer we get, the less the floor will forgive us.”
“Can it be persuaded?” I asked.
“It’s a dwarven defense.” Her gaze shifted to me. “You can insult it, if you like.”
“I was going to compliment the hospitality. The lamps are dead, the floor is trying to murder guests, and nobody’s offered us a chair.”
The next metallic click came before I could improve the joke. I squared my shoulders and held the metal marker forward. The short rod tugged toward the circular threshold, though my arm remained my own. Its warmth seeped into my palm.
“Move,” Dorva said.
She’d stopped behind Jak, one burn-scarred forearm braced against the wall. Her missing fingertip hovered near a seam between the brass plates without touching it. She watched the joints rather than the light, weighing every shudder and settling click.
“The outer plates are compensating for a bad join,” she said. “When they turn, keep your shoulders clear. They’ll catch anything standing proud of the wall.”
Jak went first. He slid across the pale strip, paused where the first band crossed the second, then lifted two fingers. “Now. Elowen, follow. Isolde after her.”
Elowen moved with careful economy. The gold around her disk tightened as she stepped, revealing a shallow groove that would’ve taken her heel. She shifted without stopping. Isolde came behind her, and the air bent around her boots as she passed the turning plates. A ring of rune plates began orbiting above the gallery, each one turning at a different speed, their undersides throwing white sparks across the stone.
My turn.
“Edrin, left foot on the bright seam,” Elowen called. “Then wait.”
I stepped where she said. The floor dipped under my weight, altered gravity tugging sideways at my knee. For one ugly instant, the marker pulled one way and my body another. I let the marker guide my hand, not my feet, and held steady until the force passed.
“Good,” Isolde said. “Don’t fight the pull. It wants a correction.”
“I’m beginning to suspect Ironfast has opinions about my posture.”
“It has opinions about everyone’s posture.”
Dorva crossed last. She didn’t hurry, but the plates above us accelerated. Jak counted under his breath, matching their movement to the three-note rhythm. Dorva reached the far side and pressed her palm to a brass join.
“All five,” she said.
The fifth body crossing changed the gallery.
Frames set into the walls unfolded in perfect alignment, bronze limbs locking forward along the gallery. Their joints made no clumsy scrape. Each movement answered the next, as if the whole defense had been waiting for the final place to fill.
At the circular threshold, an empty sentinel face turned toward us. It had no eyes, only a smooth plate beneath a crown of carved channels. White light gathered in the hollows where a mouth should’ve been.
The next tone began.
Jak’s hand dropped. “Now it’s counting.”
The blank sentinel counted us in light.
A white line passed over Jak and kindled a carving of a watcher on a wall. Dorva lit a smith at a bench. Elowen raised a healer beside a narrow bed; Isolde, a woman holding a gate against a storm. When the light reached me, a swordsman appeared in a breach with people running behind him.
Not one carving wore a crown.
“It’s sorting us by work,” Elowen said.
“It’s trying to fill empty places,” Dorva replied.
The old images moved. The watcher signaled. The smith shut a furnace. The healer lifted one end of the bed while someone smaller took the other. The woman at the gate waited until the last citizen passed. Only then did the swordsman step backward through the breach.
For one breath, Ironfast had people again.
Then the sentinel’s furnace-mouth brightened, and the floor tried to drag each of us toward the place it’d chosen.
Jak found one pale path running straight to the round door. “Together. Before the next note.”
A bright break opened beyond Dorva’s rail. “Two steps when the floor settles?” I asked.
Jak watched one pulse cross the stone. “Two. No third.”
Dorva took the rail. Elowen’s gold light exposed a dip waiting under its dust. Isolde pressed the sideways pull flat while Jak led us across.
I kept the marker against my chest and followed. Halfway over, the floor changed its mind about down. My shoulder went toward the wall. A hard pocket of air caught my ribs and held me upright.
Isolde stood close enough that her shoulder pressed mine. Strain ran through her raised arm.
“Stop means stop,” she said.
“I’ve stopped.”
Her eyes dropped to my next foot. “You were considering another step.”
“Briefly.”
Dorva reached back, caught the front of my harness, and pulled me onto settled stone. Jak crossed last. The pictures on the wall went dark behind him.
The round door drew close. Three bands of runes rose around it, and the sentinel’s face followed the marker in my hands.
The next tone came early.
The tone struck through the chamber and left my teeth aching. The rotating plates halted halfway through their turn, three narrow bands of runes standing upright around the circular frame. The brass sentinel remained beyond them, motionless except for the furnace glow moving behind its face.
Dorva ignored the sentinel and crouched beneath the brass frame. Her fingers found a seam no wider than a nail.
“There.” She struck the housing once. Something inside answered. “That round piece is the catch. The lever carries the rail. The catch tells the lock whose hand is on it.”
“And if the lock dislikes the hand?” Jak asked.
“Heat. Force. Then worse.”
That narrowed the list of things I wanted to experience. I shifted my weight and watched the three bands. Their script didn't merely shine. It leaned, each line of light sliding a fraction against the stone as the plates sought one another. A hairline tremor ran beneath my boots before the left band advanced.
“There’s the tell,” I said. “The left moves before the center. When it shivers, the gap closes.”
Isolde turned her head toward me. Her violet eyes caught the pale fire, and the rings on her fingers gave a quiet metallic hum. “You can read that from here?”
“I can read that it wants to ruin our evening.”
“A useful translation.”
The next shift began. Isolde lifted one hand, not high, just enough for her fingers to clear the dark leather at her wrist. The bands bent toward her. Air compressed between the rune plates with a heavy thump, and the central band twisted into a narrow ribbon of pale pressure.
She held it there.
Not stopped. Held. The bands strained against her control, their light fraying at the edges like hot wire drawn too thin. A current of air tugged at my shirt and pulled grit across the floor. Isolde’s shoulders stayed level, but the muscles in her forearm stood out beneath her sleeve.
“I can give Dorva one opening,” she said. “Not two. The machinery is already trying to close around the force I’m keeping out.”
Elowen stepped nearer and touched the sun disk at her throat. Gold edged the disk, clear against the light. She crouched beside the cradle and studied the floor between the broken plates.
“Dorva, show me where your boots go.”
Dorva pointed with two fingers. “Left foot here. Right inside the cradle. I turn the catch inward. Nothing crosses the bright groove.”
Elowen leaned farther, her silver-blond hair slipping loose from one side of its ribbon. The golden light from her disk traced the groove and revealed a thin line of pressure trembling just beyond it.
“That line is live. If your heel crosses it, I pull you out. Not because you're old enough to argue with me.”
Dorva’s mouth tightened. “I wasn't going to argue.”
“You were going to continue.”
“That too.”
The answer nearly made me laugh. It came out as a breath instead, because the chamber had begun to move again. Above us, suspended brass geometry rotated in impossible directions. One ring turned flat while another passed through it without touching. The change altered the weight of my body. My boots pressed hard against the floor, then grew strangely light, as if the stone had forgotten which way was down.
Beyond the inner gate, I saw more than a chamber. I saw an enchanted reliquary built on a scale that made the vault seem like a single ornament. Rune plates orbited a core of bound light. Brass arms hung in the air with their joints fixed to nothing. Crystal panes drifted through the geometry, each carrying a brief image of hands at work, a hammer rising, a door closing, a home being warmed. Every bright surface had been made for hands six centuries gone.
My palm tightened around the marker. Carrying it’d felt suspiciously like having a purpose. Giving it away felt like stepping backward.
Jak held out his hand. “Give me that.”
The left band shivered beneath my boots. I put the marker in his palm.
“Call the window,” I said. “If you miss, Dorva gets burned.”
Jak’s fingers closed around the marker. He looked at me, then at Dorva’s position beneath the cradle. “You won't get the signal back once I start.”
“Then don't make me ask.”
He clicked his tongue once, though it might’ve been strain. He moved to the outer rim, where the shifting light fell across his mismatched leathers. He raised the marker and began counting the intervals under his breath, not numbers, but short clicks of his tongue timed against the machinery.
“Hold,” he said.
Isolde drew the bands tighter. The pressure between us narrowed until my lungs had to work for each breath.
“Now,” Jak said.
Dorva entered the cradle.
Elowen watched her feet, one hand hovering over the sun disk. “Clear. Turn only while the groove is pale.”
Jak shifted the marker. The rune plates answered.
Dorva twisted the catch.
The sound was small, almost polite. Somewhere beyond the inner gate, a lock released. The circular frame opened along three vertical seams, and the brass sentinel’s face flared with light. Its head turned toward us.
It hadn’t been defeated. It had only been told that the door could open.
Inside, the reliquary’s orbit widened. Loose dust lifted into a slow ring around our ankles while a deeper mechanism began to count beneath the stone.
The plates rose from their tracks and began to circle the reliquary, each one carrying a different line of blue-white script. They didn’t spin together. One climbed while another sank, and a third slipped between them with the slow certainty of a key finding its lock.
“The floor’s going,” Isolde said.
She stood near the opened frame, one hand raised, violet eyes fixed on the dust. The air bent around her fingers. Not wind exactly, but pressure gathered into a hard invisible wall between the outer ring and the cradle.
The stone tipped beneath my boots.
My stomach rose as if I’d stepped off a roof. Loose fragments skittered toward the far side, then stopped against Isolde’s unseen boundary. She clenched her hand, and the fragments dropped together.
“I can hold the force,” she said. “Not the whole chamber. Don’t cross the pale lines unless I tell you.”
Dorva ducked beneath the nearest plate and reached the brass frame’s lower housing.
“I keep this moving, the dead thing keeps listening.”
“And if it stops?” Jak asked.
“You’ll hear me swear before it kills us.”
Jak moved along the outer rim, crossbow coming free of his back. He pointed with the hunting knife toward a narrow strip of stone between the orbiting plates. “That’s the retreat line. Don’t step past it unless I call. The plates return on a repeating count, but the gap changes when the center turns.”
He glanced at me, then at the space between us and the brass figure. “You’re the one it’ll notice.”
“I do have a face people remember.”
“It’s the sword.”
“Cruel.”
Jak clicked his tongue once without looking away from the machinery. He set a bolt against the crossbow and began marking the intervals with his thumb.
Elowen stepped beside the threshold, vestments tugged sideways by the altered pull. “If someone is caught, I decide who can move. Living person before preserved knowledge.”
Dorva’s hand paused beneath the cradle. “That may cost us the inner chamber.”
“Then it costs us.”
The deeper mechanism gave a low note, and the runes brightened.
Then light poured from the ceiling.
It fell in narrow streams, molten gold without heat, threading through the orbiting plates and gathering around the sentinel. A towering dwarven shape emerged inside it, broad shouldered and jointed in layered brass. Its face had no mouth. Its eyes opened as two square furnaces.
White script burned across its chest.
Dorva read it aloud. “Brassweld.”
The machine lowered one arm toward her. The catch answered with a pulse. Dead hands still had permission.
“Edrin,” Isolde said.
I looked at her.
“You're the blade,” she said. “We hold its world steady, and you take it apart. Stay inside Jak's calls and leave it nothing to learn.”
My grip tightened around Duskfang. The sword felt ordinary for one heartbeat, then the pact mark in my palm warmed. I let the bond run into the blade. A dusk-colored sheen gathered along the edge, thin and hungry, without changing the sword’s weight in my hand.
“And when it learns anyway?”
“Move before it does.”
I stepped onto the first pale line.
Brassweld turned.
Ironfast’s song began as three tones, each struck from somewhere below the floor. The sound passed through my teeth. More notes joined it, measured and beautiful, a work song preserved without a worker left to sing it. The light tightened around the sentinel’s limbs.
Jak’s bolt snapped across the chamber and struck a small brass tooth beside the cradle. Sparks burst. Dorva used the opening, wrenching the catch another fraction.
“Left,” Jak called.
I moved left. A plate swept through the space where my ribs had been. I cut across its edge, and Duskfang drove a black pulse into the metal. The plate shrieked past Dorva’s shoulder.
“Good,” Isolde said, and the word carried no praise, only instruction. She thrust her palm outward. The tilted gravity slammed against Brassweld’s legs, pinning one foot to the stone.
The sentinel answered with a fresh sequence of tones.
Its furnace eyes went from gold to white.
Every rune in the opened frame went dark.
“That’s wrong,” Elowen said.
Brassweld released the catch. The brass frame locked beneath Dorva’s hands. Across its chest, the old script burned away and returned in a harsher pattern.
Jak stopped counting.
“It changed the order,” he said.
Brassweld raised its arm. The song broke into a single sustained note, and the opened passage became the center of its aim.
A plate tore free of its orbit and came at us edge-first.
I ducked beneath the spinning plate as it shaved sparks from the stone behind me. Heat struck my cheek. The plate screamed past and lodged halfway in the far wall, its rim still turning.
“Jak!” Isolde called.
“Two beats!” he shouted. “Then the low sweep.”
Brassweld dragged its pinned foot free. The force around its legs buckled the floor dust into little waves, but Isolde held her ground, one hand raised, violet light threading between her fingers. The chamber seemed to lean toward her. Her rings burned white.
I had no room to admire it. The sentinel's shoulder opened along a seam, and three smaller plates slipped out like teeth from a jaw.
Jak's crossbow snapped. His bolt struck the first plate at its central rivet. The impact turned it just enough for the second to collide with it. Brass rang against brass. The third came through the gap.
I stepped onto the narrow strip of unmoving stone beside the brass frame. It was the only ground that hadn't begun to roll. The choice was ugly, but clean. Every other surface was becoming part of Brassweld's reach.
My palm warmed. Duskfang answered.
A dusk-colored sheen deepened the steel along the edge. I waited until the third plate dipped, then cut upward through the exposed joint beneath Brassweld's arm.
The blade went through with a force from somewhere beyond muscle. Metal sheared. The forearm dropped to swing from one bright tendon of brass, hot fragments bursting across the chamber, and the song lost a voice it never got back.
“Now,” Jak called.
Dorva moved.
She was compact enough to vanish behind the service housing, then suddenly there again, one burn-scarred forearm braced against the cradle while her other hand hunted across the brass fittings. Her leather apron caught a spark and smoked. She slapped it out without looking away from the mechanism.
“The catch's not where it should be,” she said.
“You said it was the third tooth,” Jak answered.
“I said the teeth were numbered. I didn't say the old fools had put them where a sensible hand would reach.”
I almost laughed.
Brassweld turned toward her.
Isolde's hand closed. Gravity seized the sentinel's chest and dragged it sideways. Its feet gouged trenches through the plates. The motion pulled the song out of tune, a low note bending until my teeth hurt.
“Keep it looking at us,” Dorva said.
“I'm trying,” Isolde replied.
“Try harder.”
Isolde's mouth tightened. The air slammed down.
Brassweld dropped to one knee. Its furnace eyes flared white, and the plates circling its body widened their orbit. The maneuver opened a path toward Dorva and closed ours. That was the adaptation. The thing had stopped trying to cut through us. It was reshaping the room.
Jak glanced over his shoulder, then back to the sentinel. “It'll cross on the next note.”
“Where?” I asked.
“Where we're standing.”
His bolt struck the brass tooth at the edge of the floor. The note came a breath early. Brassweld lunged, and I saw the tell before I understood it, a slight settling of its damaged shoulder, the weight gathering where the next plate would launch.
“Down!”
I dropped. Isolde did too, though her magic kept working. The plate passed over us and smashed into a pillar. The impact shook flakes of old mortar loose from the ceiling.
Elowen seized the moment. She stepped into the space Jak had abandoned and closed her fingers around the sun disk at her throat.
“Hold,” she said.
The word carried farther than her size should’ve allowed. Gold opened across the floor in a thin line, not a wall, not a shield, but a boundary that made the shifting plates hesitate when they reached it. The light trembled around her boots.
“That won't last,” she said.
“It only needs to last once,” Dorva called.
Dorva found the catch.
It sat behind a brass guard beneath the cradle, hidden under a false screw and a ridge of old soot. She struck the guard with the heel of her hand. It released with a click. Her missing fingertip made no difference. She’d learned how to do more with less before I ever met her.
“Jak, the count,” she said.
“Three tones. Then the upper plate.”
“I can hear the upper plate.”
“Then listen to the rest.”
Brassweld drove its damaged arm into the floor. The plates around it snapped inward. Isolde's magic buckled. Her black hair lifted in the still air, and her boots skidded half a pace toward the sentinel.
I caught her wrist and yanked her sideways. A brass edge struck where her head had been.
“Let go,” she said.
“Gladly.”
I released her. She turned with the motion, planted one hand against the floor, and sent a burst of force through the nearest plate. It spun away, scraping a bright wound through Brassweld's chest.
“Now finish what you started,” she said.
Dorva twisted the catch.
The brass frame opened.
It parted reluctantly by the breadth of a hand, revealing nested gears and a hollow lined with red glass. A breath of old heat spilled over Dorva's face. The chamber answered with a deep, resonant chord. For the first time since the sentinel woke, the song sounded complete.
Then the dead thing changed.
The red glass went black.
A seam appeared beneath Dorva's hands. She had one instant to turn her head.
“Third tooth, not the lever.”
The concealed jaw came out from inside the housing.
It rotated one way above the cradle and the other below it, two thick sections of toothed metal closing around the space where Dorva stood. The upper edge caught her working arm first. Bone broke with a hard, wet crack. Her hand struck the housing and remained there, fingers spread, while the jaw dragged her inward.
Dorva made a sound that wasn’t a word.
I moved.
Duskfang flashed in my hand. I cut at the upper jaw, then the lower. Pact force burst through both strikes. The first blow split a tooth. The second sank into a seam and stopped dead. The mechanism didn’t yield. It’d been built to answer a command, and my sword wasn’t a command.
“Edrin, back!” Elowen shouted.
I seized the cradle's edge and pulled anyway. The brass burned through my palm. Dorva's torso disappeared against the housing as the counter-rotating jaws crushed inward. Her chainmail folded. The sound beneath it was softer than the metal and worse for that.
“Dorva!”
Her head jerked toward me. Her face had gone gray beneath the light. Blood ran from the corner of her mouth. The crushed arm hung at an angle no living arm could bear.
Elowen reached the cradle and pressed two fingers to Dorva's throat through the gap. Her other hand touched the sun disk. Gold light gathered around her knuckles and spilled into the housing.
“Release the latch,” I said.
“I can't.”
“Cut it.”
“If you cut it, the jaw completes its turn.”
Her voice didn’t shake. Her fingers did. She pressed the light harder. It ran over Dorva's face and vanished into the crushed metal without closing anything. Elowen watched the pulse at Dorva's throat, counted against her thumb, and looked once at the angle of the housing.
“Her chest is pinned,” she said. “The heart and lungs are damaged. The pressure is holding what remains together. Release will kill her before I can draw her out.”
“Then stop it.”
Elowen's eyes met mine. The gold light faded from her hand.
“No rescue attempt. We finish the shutdown.”
The words struck harder than the furnace heat. I still had Dorva's apron in my fist. The leather was warm, slick, and pulling me toward the jaws.
“She's alive,” I said.
“For seconds.”
“Elowen.”
“If you keep pulling, you die with her, and the sentinel stays active.”
Isolde stepped beside us, her face gone still. One hand remained lifted toward Brassweld. The other closed around my shoulder.
“Edrin. Leave her.”
I pulled harder. Speed had saved people before. I could still make it save her.
Brassweld's furnace eyes fixed on us.
Stay.
Astarra's word struck flat inside my skull. I hated her for choosing a side.
I let go.
Isolde pulled me backward as the jaw completed its turn. Dorva’s body was pinned fully into the housing. Her head struck the brass once. Her eyes closed. The mechanism continued for another rotation, then locked around her with a final grinding click.
Elowen touched two fingers to Dorva's throat again through the narrow gap. She waited. The furnace glow reflected in her green eyes. When she withdrew her hand, she wiped the blood from her fingers against her own vestment instead of reaching for a cloth.
“Dorva is dead,” she said.
Nothing in the chamber softened.
Jak fired. His bolt drove into the exposed seam beneath Brassweld's damaged shoulder. “Third tooth,” he called. “Not the lever. I heard her.”
“I heard her too,” Isolde said. “We use it.”
She thrust both hands forward. Force struck Brassweld from opposite sides and compressed its chest. The sentinel staggered, plates crashing into one another around it. Its cracked armor split farther, revealing a lattice of red crystal and turning brass beneath.
Elowen lifted the sun disk once more. This time the gold light ran along the floor, reinforcing the narrow boundary around the brass frame and keeping the loose plates from reaching us. Her lips moved in a prayer too quiet for me to catch.
Jak lowered his crossbow and pointed with two fingers. “The third tooth is under the left shoulder. When it lifts, strike the bright line.”
“You call it,” Isolde said.
He looked at her, then at me. I took the look for a handoff.
“Wait,” he said.
Brassweld raised its arm. The damaged shoulder opened. A brass tooth rose through the broken armor, turning against the red crystal behind it.
“Now.”
I crossed the shifting ground. My boots found the unmoving strip, then the edge of a fallen plate, then the stone beside the housing. Duskfang gathered its dusk-colored sheen. I struck the bright line beneath the third tooth.
The bond drove through the blade.
The crystal lattice cracked with a sound like ice breaking across a lake. Brassweld reeled. Isolde's pressure caught it and held it upright. Jak's next bolt punched through the opening. Elowen's golden boundary kept the returning plates from closing around us.
For one breath, all four of us worked around the space Dorva no longer occupied.
Brassweld's furnace eyes remained white.
Its arm rose again, slower now, but still moving.
The song continued beneath our boots. Dorva’s hammer lay near the cradle, its head turned toward the ceiling. I could see one gauntlet and one braid gone gray with dust, and nothing else.
My hand went toward the housing.
Elowen caught my sleeve. “The pressure shifts if we open it. If the vault changes mode, the jaws retract and lock. Touching it now loses the chance to recover her.”
She couldn’t promise more. I could see that in the grip she kept on my sleeve.
Jak tracked the turning arm. “Next window after the fourth note. Six breaths after the low answer.”
“We finish the shutdown,” Isolde said. One hand held Brassweld’s raised arm a finger’s width off its path. “Then we come back for her.”
I wanted to ask whether Dorva had heard the last command, whether any part of her had stayed awake beneath the crush. No one in the room could answer.
I raised Duskfang between the living and the machine. “Finish the shutdown.”
The control ring answered with a deep metallic cough. Plates slid beneath my boots, and the floor tilted toward the sealed cradle. For one breath, my stomach rose into my throat.
“Don’t take the lever,” Jak said. He’d moved to the outer rim, crossbow braced against his shoulder. His eyes tracked the gaps between the moving plates. “You’ll have one passage when the upper jaw lifts.”
“How generous of it.”
“It isn’t.”
He fired. The bolt struck a narrow brass catch above us. A panel folded back, revealing a crawl of black metal and teeth. The opening lasted only because the bolt held the catch crooked.
Isolde planted herself beside the turning housing. Wind burst from her in a hard circle, lifting dust and loose fragments from the floor. Her rings flashed once. The bands that had begun to close around the mechanism shuddered apart under her control, leaving a narrow gap through the machinery.
“Go,” she said. “I can hold this for seconds, not miracles.”
Elowen knelt at the golden boundary. She touched her sun disk, then pressed two fingers to the stone beside Dorva’s trapped form. The line widened by the breadth of a hand and revealed the angle of the body beneath the brass.
“She’s clear of the moving parts,” Elowen called. “I’m marking this position.”
She drew a second golden sign across the floor. It ran bright from the boundary to a cracked pillar and held when the ring lurched again. The work left her shoulders tight, but her hand didn’t shake.
I slid through the opening Jak had made. Brass scraped my shoulder. The passage narrowed at once, and something inside the wall began to move. I saw only a blur of jointed metal before it struck.
Duskfang came up. The blade’s dusk-colored sheen gathered along its edge, and my cut met the moving arm with a crack that numbed my wrist. The force drove me sideways. A thin edge caught my sleeve and missed the skin beneath it by the width of the leather.
“Edrin,” Elowen said.
“Still handsome.”
“Skin?”
“Untouched.”
Another plate shifted behind me. There was no room to turn, no space to swing properly. I set my boot against the wall and pushed toward the only gap I could see, following the gold line Elowen had drawn. The mechanism groaned around my ribs.
Jak’s second bolt struck above my head. A tooth withdrew from the wall, exposing three identical points along a narrow rail.
“First is false,” he called. “Second locks the arm. Third releases the main lock. Wait for the upper plate.”
“You could’ve mentioned that before I entered the brass throat.”
“You’d already moved.”
I almost laughed anyway. Then the upper plate began to rise.
I reached for the obvious lever. It stood within arm’s length, thick and red-marked, made for a hand like mine. My fingers closed around empty air instead.
The lever stood where a hand like mine would look first. The tooth was smaller, half-hidden beneath a lip of brass. I dropped lower and drove Duskfang into the gap beside it. Pact power ran through the blade, a cold pressure tightening my grip and sharpening the edge. I didn’t try to break the rail. I only held the plate away long enough to reach.
“Now!” Jak shouted.
His bolt cut past my cheek and struck a pin behind the third tooth. The mechanism jerked. I hooked two fingers around the tooth and pulled.
For a moment, nothing happened.
Then every command plate in the ring turned toward me.
Isolde’s wind slammed into the bands. Her boots skidded across the stone, but she stayed upright, one arm extended and the other pressed against her ribs. Violet light flared through the seams of the housing.
“It’s asking for a final hand,” she said. “Do I give it one?”
Elowen looked from the moving plates to Dorva’s body. “If you finish, the lower vault seals.”
“The archive?” Jak asked.
“Sealed with it.”
Something heavy crashed beyond the ring. A section of the outer machinery folded inward, crushing a stack of brass frames and sending sparks through the air. Whatever salvage had been waiting behind that wall was gone beneath the closing plates.
Isolde’s eyes found mine across the machinery. “If I release this, the core wakes again.”
She held my gaze. The third tooth cut into my fingers, and my hand wanted to let go.
“Finish it,” I said.
Isolde turned her wrist.
The wind vanished inward. The bands snapped together around the command housing, not crushing it but pinning every moving part in place. The chamber gave one enormous shudder. Jak’s bolt broke. I pulled free and threw myself toward Elowen’s golden line as the floor dropped beneath me.
A brass edge scythed for my forearm, and I had no time to dodge.
Darkness came off my skin to meet it. Not shadow lying on me. Shadow standing up: a literal layer of it, thick as boiled leather, sheathing my forearm in solid dark the color of deep water. The edge that should have opened me to the bone skated off it with a sound like a struck bell. The impact still shoved me. The pain never arrived. For half a breath my whole arm wore the dusk that usually lived on Duskfang's edge, and then it drained back under my skin like something patient returning to its den.
Armor of Shadows.
I waited for the price.
There isn't one. This is yours.
“Move,” Elowen said.
I moved.
Jak seized the back of my collar and dragged me clear as the final plates settled. The song thinned into a single note, then stopped. Silence filled the ring so completely that I heard my own breath stumble.
Gravity eased beneath us. Dust that had hung above the floor descended in slow gray veils. The gold boundary held. Beneath it, the brass cradle gave a heavy click as its floor clamps disengaged. The counter-rotating jaws stayed locked around Dorva. Nothing withdrew.
Elowen leaned over the opening. “Recoverable,” she said. “Not now. The floor still has charge.”
Isolde lowered both hands. The violet light faded from her eyes, and the ruined outer machinery gave one last settling groan.
Along the far wall, doors sealed the archive while the largest salvage frames lay crushed behind them. For now there was only the quiet cradle, the dormant ring, and four living people where the machine had demanded five.
Jak looked toward the darkened controls. “Brassweld’s stopped.”
I flexed the forearm the vault had failed to open. The skin was unmarked, and the shadow beneath it felt rested rather than gone. Part of me wanted the machine to try again. Dorva was still under it. I lowered my arm and kept Duskfang ready while the last plates went still.
The room stayed still long enough for dust to settle. Nothing struck us. Nothing opened. The cradle no longer drew power, but its jaws remained clamped around Dorva beneath Elowen’s gold boundary. One hand lay palm-up between them.
I took a step toward her.
“Not yet,” Elowen said.
“The charge is gone.”
“Most of it. Most isn’t a condition I use for lifting bodies.” She kept two fingers on the sun disk at her throat. “Dorva first. Archive and salvage after.”
Dorva’s hammer lay beside the cradle, half an arm’s length from her open hand. I picked it up and slid it beneath her belt, where she’d carried it. The leather creaked. Nothing else moved.
Jak checked the gallery mouth, the ceiling, and the path behind us. “The approach is open. Inner gates are dead. We go back through the gallery with the broken statues and up the sloped passage.”
“You sound almost cheerful.”
“I’m saving it for outside.”
At the sealed wall, Isolde pressed violet threads into the existing custody marks. Each break in the pattern closed with a faint glimmer.
“Those will show if anyone tampers?” I asked.
“Yes. The archive can wait.”
Elowen faced me. “Bring the leather strap from Jak’s pack. You take Dorva’s shoulders after I release the restraints. Jak takes her feet. Isolde watches the plates. Nobody pulls until I say.”
Jak passed me the stiff old strap without looking away from the gallery. I wound it around my hand and slid it beneath Dorva’s shoulders.
In memory, her voice cut once through the machine’s roar: third tooth, not the lever.
Elowen looked up. “Ready?”
I took Dorva’s weight against both hands. “Ready.”
Behind us, in the dark beyond the settled plates, one brass tooth turned.
It stopped before anyone else looked up.
