F-Rank Mimic Chest: My SSS Mimic Skill Lets Me Become Anything

The root found Dane’s old brass tag and pulled on both nails.

Come home entered him without words.

His Door spine leaned toward the western bay. Coffin warmth shifted beneath the wounded man as if preparing a shelf. The four Wagon struts loosened to roll wherever the machine dragged them, and Dane’s three working Stall ribs folded from the thick cable they had uncovered.

The mortar worker felt the lining move. His next breath stopped halfway above the thigh pack.

”Still open?”

Dane struck his crosspiece once.

The answer traveled through the root before its echo reached the landing. Return pressure swelled around it, trying to make one yes serve two questions.

Kett’s gray box slammed onto an evidence groove. ”He answered the man inside him. Leave the rest blank.”

Iron scraped black wax ahead. The Slate Copy had shifted against the root; Dane knew its weight by the three claim threads that tightened across his Door, Coffin, and Wagon patterns. Deeper in the machine, bay chains woke one after another.

”Return teeth live,” the claim-feed technician called from the north side. ”All four bays. Separate order behind it.”

The Door thread tried to straighten Dane for storage. Coffin pressure nudged the worker toward the compartment that had once held bodies without asking them. Wagon lines pulled his front and rear struts apart. Paper tightened along the fine grain of every Stall rib.

Nothing detached. It only hurt in four places at once.

The old loop burned through axles it had never touched. The split around Ada’s rod one pressed into four memories of the same wound, while hunger clenched under the passenger band and asked why warm meat was being protected from a useful room.

Behind Dane, boots cleared the north threshold. The damaged wedge knocked stone twice as Toma tested it.

”We can leave the root,” Brant said. His strapped arms kept his voice from becoming an order his body could enforce. ”Door is open. We have wounded people and one construct between us and work nobody here has survived.”

Ada held rod one beneath the split. ”If the cut slips, it could strip a Form or rip the tag through his side. The failure might reach the cradle. I can keep the pack compressed. I can’t promise Dane’s body holds.”

”Mine either,” the mortar worker said. He drew a careful breath. ”Still choosing open. Still no lid. Don’t let that machine call me stock.”

”It won’t,” Ada told him. Her fingers stayed on the pack.

Vera’s boots stopped outside Dane’s reach. ”Move the living route. The root belongs to Dane’s decision.”

Rope rasped around the north pillar. Voss took the high pull and Kril set his boots for the low. Six metal feet settled behind them: two distinct choices from the coffer, followed by the familiar rattle of four habits. Holt stayed at the cradle. The lye-scarred and flat-handed workers raised Buk’s litter while Jessa led the one-armed owner farther north. The former scheduler kept Tess close enough for the cord to brush both their boots, and the shorn worker rolled Kett’s cart clear of the bay line.

The root jerked. Ada swore and drove the pack back into place.

Above the broken bays, Grib’s voice remained offensively calm. ”Damage to original service roots voids repair eligibility and every surviving protection of the inventory code.”

”You never protected the inventory,” the technician said. Their ink-burned arm slapped a loose chain quiet. ”Brace that rung or fall off it.”

Kett opened one public source line. Its vibration reached Dane through the groove under his strut.

”Three fibers in the sheath,” Kett said. ”Recovery. Inventory. The claim Grib built from Nate’s death. I can prove where they run.”

Buk tapped Pell’s broom handle against the litter frame. ”Root bends under Door bay. Pull north, soft joint rolls to ribs. Feel for the thin place.”

”Keep the tag route away from the bays,” the technician added. ”The sheath will turn one fiber into reach at a time. If it snaps back, it takes the Stall side first.”

Ada’s thumb found the edge of Dane’s split and stayed there. ”Twelve hard breaths. After that, the shared fault stops being pain and starts becoming damage.”

The draft from the north corridor moved across Dane’s open lining. He heard the one-armed owner stumble, Jessa catch him, and Toma curse at the wedge. A retreat existed close enough to measure by breath.

He could take it with the root still inside him.

Brackenvault could wait. Any ordinary stone connected to the dungeon could carry return into the nails later, when the company slept or Ada’s hands were busy or Vera stood too far away to hear the first scrape.

The pull softened.

F-1 Ambush Chest opened inside the pain.

His Door became a thick lid with a straight hinge. Resin covered the peeled grain. The dead strip answered when he moved it, and the split around rod one closed so completely that Dane could no longer remember which side had hurt. Hunger settled into a quiet place where commands would decide when it mattered.

The man in the cradle stopped being a person Dane might fail. Brackenvault marked him approved contents and promised treatment.

That was the worst kindness in the offer.

Let the dungeon choose prey. Let it name responsibility. Take the repaired body and never again wonder whether mercy had been courage or a slower way to kill someone.

For several heartbeats, Dane wanted the relief more than he wanted to be proud of refusing it.

Then the worker’s packed leg trembled against the open lining. He was warm, frightened, and still waiting for Dane to keep the answer he had given.

Dane rolled his front struts toward the root.

Kett’s public line scratched one short mark. No praise followed.

Dane opened Four-Form Coordination.

He gave the four bodies their order once: Door brace, Coffin hold open, Wagon step, Stall cut.

The first breath drove his crosspiece into the command spine. A flat slab of the Slate Copy struck from the other side, bending living grain until the lower loop bit deep. Dane held the upright line between the blow and the cradle.

Holt counted the worker’s breathing. Ada kept his face, chest, and feet clear while the lining tried to cup him tighter. Voss and Kril drew the guide rope north; four struts took their pull and carried it through Dane’s side into the tag.

The nails heated.

All three ribs reached into wax, but only the damaged one found Buk’s soft joint. Fine grain entered the seam and read layers by tension: sheath, old adhesive, then something narrower that tightened whenever the machine called him recovered property.

”Three,” Holt said into the worker’s exhale.

Dane crossed two ribs around the narrow fiber and cut.

It parted with a wet-cable snap. Every recovery reel in the western bays screamed backward. Brass tabs tore loose and struck stone in a spray of hard notes. The command dragging his Door spine home went slack, and one clean inch of his body belonged to gravity again.

The root wrenched the tag sideways, burning both nails white through the living grain while Grib shouted from above that the cut remained reversible.

Dane rolled another fraction north.

At the sixth breath, the sheath turned a second difference beneath his ribs. This fiber carried cupboard pressure, shelf depth, and the old certainty that anything inside him could be counted before it could be asked.

The Slate Copy abandoned the root and hit his crosspiece with its full weight.

One plate hooked the Door edge. A counting corner ground down his right side toward rod one. The contact told Dane more than sight could have: the construct was high on his left, driving across him, with its lower seam open wherever Kril’s hook scraped sparks from wax.

”Voss, pull it high,” Brant said. ”Kril, spoil the base. Vera, give Dane a floor.”

The hook chain snapped taut above. Kril rammed metal into the low seam.

”Front-right clears,” Vera called from beyond Dane’s reach. ”Quarter turn toward my voice. Stop when the rope leaves your axle.”

Dane turned. The counting corner passed rod one close enough for Ada to feel wind from it.

”Collector fold on its left!” Tess shouted. The restraint cord scraped as the former scheduler stopped her advancing. ”Silver paper under black wax. That’s what moves the elbow.”

The technician lunged into the bay noise and tore the paper route. Slate’s pressure stuttered against Dane’s crosspiece.

His ribs closed on the second fiber.

The cut emptied inventory pressure from the drawers. They burst open with a clatter of brass teeth and old sheets skidding across stone.

”Historical trash,” the technician called. ”Glove recovery, copper destruction, dissolved token. Nothing came out of him.”

Kett’s box stayed shut. So did Dane.

The sheath contracted around the last fiber, thick with years of commands laid over Grib’s claim to Nate’s death. Returning became the sensible shape of every relief it offered.

The repaired composite settled over him again, fitting four Forms without friction while the passenger received approved treatment and Vera’s debt moved beneath Thorne’s protection. Hunger became a scheduled task instead of a private terror.

Dane felt how easy it would be to let a better-built body make his choices look inevitable.

On the ninth breath, Slate caught the dead left rib.

The useless strip tore against its one living attachment without breaking. Shared instability carried the pull through every pattern: Coffin warmth lurched beneath the worker, the right split ground against rod one, Door grain bowed, and all four axles tried to fold toward the same bad angle.

The mortar worker groaned. His hand struck the open edge, not in command but to prove he was still conscious.

”Pack holding,” Ada said. ”Dane, stop or take the last pull. One for continue. Three for stop.”

Vera’s boots held their place outside his reach; Ada’s question stayed between doctor and patient.

Dane struck once.

Return pressure seized the impact.

Kett drove the edge of his closed box into the groove. ”Ada’s question. Current load only.”

Holt’s count reached ten with the worker’s next shortened breath. Dane braced Slate against the command spine while Voss’s rope creaked overhead and Kril fought to keep the lower seam open.

At eleven, the Wagon struts rolled north. Both tag nails pulled hot through living wood, but neither tore free. The sheath stretched between his ribs and the machine until the final fiber hummed against all three cutting edges.

”Twelve,” Ada said.

Dane closed his ribs.

On the same breath, he released the high-load coordination that held Door, Coffin, Wagon, and Stall inside one command.

The last fiber resisted long enough for the old F-1 body to become painless once more.

Then it broke.

The root recoiled through the service joint and tore free of Dane’s ribs. Cold rushed into both nail channels. The brass tag remained fixed to his side, every stroke still present, while the emptied pressure left the nails hanging in hollow channels.

Slate drove one stored step into him after its authority died. Its weight struck the command spine; the spine answered by folding. Service plates slammed from opposite sides, caught the construct between them, and sheared brass through wax. Counting joints burst across Dane’s crosspiece. A slate corner struck stone, cracked, and disappeared under the grinding wall.

Nothing in it screamed. Nothing tried to crawl back.

The three severed commands took their bays with them. Recovery reels ripped from their housings. Inventory drawers spat teeth and false paper. The kill-credit chain hauled half the gantry sideways before its anchors tore out, sending black wax roots whipping through the gap it left.

A broken plate carried one piece of Thorne’s voice—”Roo—”—and shattered beneath falling brass.

Metal boomed across the north lane.

”Stretcher!” Holt shouted.

”Coffer front,” Brant answered.

Two different choices knocked from inside the six-legged coffer. Its four habits rattled after them as all six legs drove the sealed body beneath the falling support. The toothed beam struck its lid hard enough to shove it a handspan across stone.

Voss’s hook caught the high tooth. Kril jammed Cutter’s abandoned lance beneath the low one and put his whole weight on the shaft. Holt and the rear carriers dragged the unknown adult through while breath scraped in that stretcher’s chest.

The coffer backed out with six legs and six patterns intact.

A loose root lashed Dane’s rear struts. High-load coordination was already closed. He took one slow Wagon step instead, letting the separate components settle around the old fault rather than forcing them through it.

”North, now!” Brant called.

Voss and Kril hauled. Dane folded the Stall ribs, kept a simple Door brace, and rolled with his Coffin lining open around the worker. Ordinary hands and rope took them through the north door.

Behind them, boots hammered toward the same exit—then reversed. A gray seal rang against console teeth.

”He’s going back for it,” the technician said.

The old inventory barrier dropped with a crash. Grib hit the bars from the machine side; the technician cleared them by less than a stride. The two bodies already lying beyond the landing remained there with him among the dead bays.

”Emergency management review!” Grib shouted. ”Open this before the department loses institutional memory!”

Nobody spent a breath answering.

The corridor ended in a square service refuge. Voss and Kril lowered the manual inner bar into its stone brackets, and Toma drove the damaged wedge underneath until each blow traveled through Dane’s struts. No claim line followed it.

Ada leaned over the cradle. ”Dry shelf. Same pack. Do you want out?”

”Out,” the mortar worker said.

Ada, Holt, and the lye-scarred and flat-handed workers lifted him without changing the compression. His breath remained rough but regular. Once his feet cleared Dane’s open edge, the lining held still until every hand had withdrawn.

Brant counted by asking for the lives most likely to go quiet. His boots found Holt’s stretcher first. ”Rear litter?”

Holt bent close enough for his sleeve to brush the frame, listening through two breaths before he answered. ”Shallow, but holding.”

The one-armed owner coughed before Brant reached him.

”Conscious and complaining,” Jessa said. The man made a hoarse sound that supported half her report.

The former scheduler named Tess. Buk knocked Pell’s tab once and the crossed brooms twice. Kett’s gray box stayed sealed under his hand. Two awake replies came from the coffer, followed by four familiar rattles. Toma and Jessa answered; Voss, Kril, Vera, Ada, Holt, Shorn, both litter workers, and the remaining north-side adults filled the refuge with tired voices or boots.

The claim-feed technician sat against the barred door. ”Count me alive. Don’t count me Ash Company.”

Brant accepted the first statement and left the second for later.

They held silence for sixty counts. At first, brass and stone kept falling beyond the bar. Grib tried three emergency classifications, each farther away than the last. By the end, Dane could hear the worker breathing on the shelf and nothing moving toward them.

The System waited until the count finished.

F-2 -> F-1: Self-Claimed Mimic

Basis: four chosen Forms + severed ownership + independent choice witnessed

Control: 0.10% / Cognition: 6

Ordinary Brackenvault tag command route: severed

Four-Form Coordination and shared instability retained

No repair granted

No flesh filled Dane’s frame. Hunger remained under the empty cradle. The dead strip carried no weight, the peeled rib stung, the split stayed around rod one, and every brass nail remained exactly where Grib had driven it.

Someone tested the refuge’s two farther passages.

”Upper gate is Thorne’s pattern,” the technician said. ”Short route. It wants all four Form signatures live from entry to exit.”

Buk dragged a broom end over the lower threshold. ”Old warren cut. Kesh work. Road takes labor before it takes coin.”

”No road tonight,” Brant said. ”We have a bar. Use it.”

Nobody argued, and nobody chose what came after the night.

Dane sent the smallest possible answer toward the tag: one grain of pressure into the first nail channel, then the second.

Only the old pain came back.
