Calder Voss died with a condemnation stamp in one hand and an appraisal knife between his ribs.

I knew the knife was mine because I had sharpened it that morning. It was meant for scraping varnish, testing mortar, and exposing counterfeit enchantments. The Guild forbade appraisers from carrying weapons, so it issued us tools that became weapons only after someone put one through your coat.

My inventory slate lay open beside Greymarrow’s heart conduit. The numbers on it were impossible. A dungeon declared exhausted should not have been sending a second pulse through a sealed Guild pipe.

A gloved hand took the slate. A voice flattened by a Guild respirator said, “You should have signed the valuation, Calder.”

The condemnation stamp slipped from my fingers. Brass struck stone. The sound followed me into the dark.

Then something hit my lid.

I woke furious at whoever had shut me in a box.

I tried to inhale before shouting. Nothing happened. There was no pressure in my chest, no air in my throat, and no throat to object. Panic arrived anyway. I heaved against the darkness.

The darkness opened. A slab of wood swung upward with a rusty squeal. Grey light revealed collapsed shelves, broken tile, and a copper pipe torn from the wall. Then the slab dropped with a hollow bang.

It took me several seconds to understand that the slab was not above me.

It was me.

I opened it again, slowly. My sight did not come from eyes. Blurred images gathered through three dark knots in my wood. Where their angles overlapped, the room sharpened. Colors were dull. Edges and movement were painfully clear.

I sat on the floor as a squat wooden chest, perhaps three feet wide and two feet deep. Tarnished iron straps hugged cedar boards darkened by age. The lid was my upper jaw, hinged along what I could only consider my back. Below it waited a hollow interior lined with pale, flexible fibers. They stirred when dust touched them.

I had no arms, legs, lungs, heartbeat, or skin. Every board registered pressure, and my base caught vibrations. A corroded keyplate beneath my lid served as a poor substitute for a face.

I attempted to say, “No.” My lid clacked. The sound was less a word than a cupboard losing an argument.

Panic surged again. I forced the lid closed. Cords threaded through the wood, answering thought with slow pressure. My body was built according to assumptions I found professionally offensive.

Pale lettering appeared behind my closed lid.

[SYSTEM]

Identity continuity detected.

Form: Lesser Wooden Mimic — Level 1

Species status: Extinct

I opened myself. The lettering faded.

“Extinct” was a legal classification I knew too well. It appeared on salvage permits when a species could no longer complicate profitable work. Mimics had been gone for more than a century. Guild histories called the last purge an unpleasant necessity, making blood sound hygienic.

Either the histories were wrong, or I had achieved a particularly bureaucratic form of death.

I tried to move. The boards along my base flexed. My left corner lifted the width of a coin, scraped forward, and dropped. After four attempts, I had turned perhaps two inches and acquired a detailed understanding of despair.

Something metallic pressed against my rear band. Its shape emerged through contact: a coiled strip of steel, one end snapped, trapped beneath my back edge. The pale fibers inside me reached toward it.

Hunger arrived as an ache in every seam, demanding shape and substance. I felt carbon folded through iron and heat fixed into the steel’s curve. Part of me knew I could take it apart without tools.

Another display surfaced.

[SURVIVAL TRAIT: CLAIM PROPERTY]

Completely consume one nonliving object or crystallized monster core. Learn one available property.

Pattern Vault: 0 learned | Active slots: 0/3

The fibers lengthened over my lower lip like pale roots seeking water. The steel smelled of rain on a forge, and I wanted it with a force that made panic seem mild. I stopped them an inch short.

Thirty-four years as a human deserved more than immediate surrender to predatory urges. Also, any appraiser who accepted the first offered acquisition without inspection deserved his losses.

I rocked until my rear edge climbed the coil. Contact clarified the object. Blue scale and quartz grease marked a Hallowmere-pattern pressure regulator from a floor trap. Cheap regulators used layered bronze. This was heat-cycled spring steel, built to accept force and return it. One broken end had made the crew discard it, but the working coils remained sound.

Value was rarely the same thing as condition.

I let the fibers close. They drew the spring into my hollow, and my lid slammed without permission. Inside me, steel softened with tiny crystalline pops. The object came apart against the fibers, flaking into red light that soaked through my wood.

For one alarming moment, I understood the spring better than I had understood my own hands. Three aspects separated themselves.

[CLAIM: TEMPERED PRESSURE SPRING]

Stored Tension: Store limited force from impact or resisted movement; release it in one burst.

Tempered Flexion: Bend farther before cracking.

Fatigue Resistance: Reduce wear from repeated stress.

Choose one.

Tempered Flexion would make this fragile body less likely to split. Fatigue Resistance promised long-term value. Both were sensible. Neither solved the fact that an ambitious snail could overtake me.

Stored Tension was riskier. “Limited” concealed more than it explained, and a burst without steering could turn me into firewood somewhere else. But it offered movement and leverage. A property’s best use did not always match its intended one. That principle had paid my rent for twelve years.

I chose Stored Tension.

[PROPERTY LEARNED: STORED TENSION]

Pattern Vault: 1 learned | Active slots: 1/3

Instability: Stable

The iron straps around me drew tight. A new awareness spread through my hinge and boards. I pressed my lid against a fallen shelf brace. The brace resisted; the property converted my effort into pressure stored through my grain. It was not pain exactly, but a mounting need to move.

I released it.

My lid snapped wide. The recoil kicked my entire body backward. I struck the floor, rolled onto one corner, and crashed upside down. For several seconds I stared at the world through badly aligned knots.

The experiment established three facts. I could move quickly once. I could not steer. And dignity was no longer among my immediate assets.

I flexed my lid against the floor, but there was not enough room to open it fully. Each attempt rocked me and scraped splinters from my rim. I had nearly gathered enough force for another try when footsteps sounded beyond the chamber.

Human footsteps.

I went still. Yellow lantern light widened under the half-open door. A key grated in the lock.

“Thought they cleared this room,” a man said.

“They cleared anything worth carrying.” A woman answered. “We’re here for the copper spine.”

The door struck broken tile and stopped. Boots pushed through. From my overturned position, I saw two workers in dust-grey Guild reclamation coats. The man carried a pry bar and chain. The woman held a hooded survey lantern and a clipboard.

I tried to look like an ordinary chest. Being upside down weakened the performance.

The woman swept her lantern across me. “Was that on the salvage sheet?”

The man nudged my side with his boot. Every fiber inside me lunged toward the pressure. I clamped my lid shut before I could clamp it around his ankle.

“Rotten coffer,” he said. “Iron’s not worth the cart space.”

My professional pride objected to his methodology. The rest of me was relieved.

They crossed to the torn wall. A copper conduit thicker than my old wrist ran through exposed stone and disappeared behind a cracked pier. Green corrosion covered it. White inventory marks read: DECORATIVE CHANNEL. NONARCANE.

Wrong twice.

Blue mineral veins had grown around the conduit’s clamps. It was a tension brace distributing the vaulted ceiling’s sideways push, disguised as ornament so delvers would hesitate to steal it.

The man uncoiled his chain. “Hook the third clamp. Winch team can pull from the corridor.”

The woman did not move. “The appraiser’s report said the east intake was unstable.”

“The dead appraiser’s report.”

“Calder Voss died in the south register room. How did he survey this side after the accident?”

Silence held. The man lowered his voice. “Provost Veyr signed the sequence. Challenge his dates after we’re paid.”

If I had possessed blood, it would have gone cold. Lucan Veyr headed condemned-property reclamation for three provinces. He had assigned me to Greymarrow and demanded my findings directly. He knew I had surveyed the east intake before visiting the register room.

The official story was already written. I had died in an accident. Any work that contradicted the timing would be adjusted until it behaved.

The woman consulted her clipboard. “Demolition warrant activates in thirty days. Why strip a brace today?”

“Because in thirty days the breakers take the whole hill. Core, walls, vermin, all of it. Veyr wants salvage closed before the heart crew arrives.”

The word heart passed through my wooden body like a cold nail.

The man fed his chain around the copper spine and shouted into the corridor. A distant voice answered. Links tightened.

The obvious move was to make noise: warn them, reveal myself, and trust two reclamation workers to respond calmly to an extinct predator. I valued that plan at zero.

The chain snapped taut. Dust sifted from the pier. The conduit would resist perhaps three pulls. When the second clamp failed, the pier would rotate. The ceiling’s first slab would strike the shelving beside me and drop its top rail across my position.

A drainage slot waited six feet away at the base of the opposite wall. I could fit if I reached it upright. One blind launch would not be enough.

Something moved inside the cracked pier.

A tiny hand appeared between two stones. Its fingers were the color of old candle wax. A creature squeezed into view no taller than my former forearm. It had a narrow face, large black eyes, and a soft horn bent over its brow like an unlit wick. One leg dragged behind it.

The workers had not seen it. Their attention stayed on the chain as the creature crawled toward the drainage slot.

The first clamp tore free. Copper shrieked against stone. The little creature froze beneath the shelving rail.

I had spent twelve years telling myself an appraiser did not decide what deserved to survive. We recorded. We classified. We gave decision-makers accurate values.

Launching toward the drain alone was logical. I was the last known member of an extinct species. The creature was an unidentified monster in a condemned dungeon. Guild arithmetic made the choice simple.

I had seen what Guild arithmetic did with inconvenient lives.

The second clamp began to bend. I forced my lid against the floor. Upside down, I could open it only a few inches, but resistance accumulated. Stored Tension filled my bands. I held it until a split stung along my left rim.

Then I released one side before the other.

The uneven force spun me onto my base.

The man turned. “What was that?”

I opened my lid against the fallen shelf brace and pushed. Force gathered faster now. The shelf creaked downward over me.

The second clamp tore loose. The pier shifted. Stone thundered overhead.

I released.

The burst threw me across the floor. I hit the wax-colored creature broadside as the shelving rail crashed down. It made a thin, furious squeak. We tumbled together. My front edge struck the drainage slot, and momentum folded me through with the creature trapped against my side.

The first ceiling slab fell behind us. Noise became weight. My lid struck stone, and a crack raced through one cedar board. Dust swallowed the lantern light. Beyond the collapse, the workers shouted as they ran.

I slid down a chute slick with mineral residue and struck a shallow basin. Grey water flooded my hollow, cold and metallic, then drained through seams I had not known I possessed. For a while, nothing moved except settling grit.

The little creature rose beside me. Its injured leg shook. A faint amber flame kindled at the tip of its bent horn, revealing a cramped maintenance passage ribbed with pale stone.

It stared at me. I stared back with all three knots.

“You’re welcome,” I tried to say. My lid produced a tired click.

The creature placed one warm hand against my cracked board. Its flame brightened. It tapped two fingers against the wood—tok-tok—with the solemn care of a ritual. Then it limped into an opening I could not enter and looked back once before disappearing.

I was damaged, trapped below a room that had partly collapsed because I had not warned the people dismantling it, and thirty days from being broken with the rest of the hill. Still, the warm print on my wood felt like the first honest payment I had received in years.

Cold answered it from beneath me.

The basin’s stone was threaded with exhausted blue mineral. I recognized a dungeon’s sensory lattice, dry almost to extinction. When my base touched it, a pressure entered my grain. Not force. Attention.

An image flickered through me: a crystal suspended in darkness, once the size of a man’s torso, now webbed with black fractures. Thin pipes pierced the chamber around it. Beyond the walls, small frightened shapes hid in sealed rooms, each a weak point of warmth.

The contact recoiled, then returned with desperate caution.

Mimic?

The meaning was not spoken. It arrived as wonder wrapped around old terror. I pressed my base against the mineral thread.

“Greymarrow?” My lid clicked, but the lattice understood intent.

The dungeon showed me a brass condemnation stamp falling beside a dead man’s hand. Then a glass conduit drawing blue light out of a wounded crystal.

The second pulse from my final inventory.

Not treasure. Not mana.

Something the Guild needed an appraiser not to recognize.

The presence beneath me weakened. Its next thought barely crossed the stone, but every word carried the weight of a mountain trying not to beg.

Calder Voss, Greymarrow whispered through every splinter of me. Do not let them take my heart.
