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

Brant stopped outside the old hazard room.

Vera’s three warning slips still marked the walls. The red route stroke crossed the threshold, cracked cleanly through her licensed-liability curve. Beyond it waited parallel iron scuffs, rat stains, and an empty rectangle where a chest had stood.

Brant lowered the hook across the entrance. "Outside the mark until I clear it."

Vera obeyed her own order from that morning. She opened the crystal’s padded case but left the glass inside while Brant tested the floor, rear wall, and service slit from beyond the threshold.

The rear warning lifted in a draft.

Blue-gray lines showed beneath it: hook, cup, and trailing line rubbed to resemble a boot scuff.

Tess looked away too late. Holt closed his frayed prayer cord around one fist.

Vera watched both reactions. "Whose code?"

"Mine," Tess said.

"Who saw you place it?"

Holt answered before she had to look at him. "I did."

The old room had held a forced feeding, a licensed warning, and two decisions made behind Vera’s back. Vera kept her first questions behind her teeth. The fresh drag trail set the earlier deadline.

"Thirty breaths," Brant said. "Exact purpose, then we move or withdraw."

Tess took the blue chalk stub from her inner pocket and offered it to Vera. "The code asks recovery networks for an intact capture team. Quiet carts, warded chains, paid labor. I placed it after you left."

"Using my seal as cover."

"Yes."

"And the wrong collector?"

Tess’s fingers remained open around the chalk. "Could reach him first."

Vera took the stub. "You surrendered tools after the vote and kept this one."

"Yes."

Holt spoke through a dry throat. "I meant to tell you before we cleared the bend. Then movement became an excuse I was relieved to have."

"You will both give me the full order after we leave this floor." Vera put the chalk beside the cased crystal. "Until then, Tess gives route knowledge from the rear and touches nothing. Holt records every order, including this one."

Neither asked for forgiveness. That preserved enough time to follow the trail.

Brant crossed first. Iron scuffs cut the chalk in two tracks, each as wide as a roller. Crescent gouges under the empty footprint showed where hook bars had struck the base rings. One gouge was shallow; the second bit stone on its way in.

"Uneven first catch," Brant said. "They tilted him left. Dropped him once."

Holt wrote the sequence while Vera waited for Brant to test the center, then entered and knelt beside the cracked seal without touching the wax. Its break met the seam of a false rear slab.

"The service door opened through my liability stroke," she said. "The Core kept the warning and removed what it warned against."

"Asset relocation before a classification hearing," Brant said.

"A thinking hazard moved beyond licensed observation."

His gaze lifted. "That word will cost you under oath."

"Then the hearing will learn what careful costs."

Brant set the hook into the rear seam and leaned his weight through the long shaft. Mortar cracked. A low stone panel shifted inward, revealing rails, chain grease, and fresh black-red resin scraped from Dane’s cured side.

Six sets of narrow heel marks overlapped beside the chain wheel recess. Two workers had braced the brake, two had hauled chain, and two had guided the hook bars. Brackenvault’s staff had not improvised a theft. They had followed a practiced movement plan.

Holt stared at the under-base gouges. "There should be a rule for moving a mind."

"There are rules," Tess said from the rear. Her usual market humor stayed absent. "People with enough access learn where the rules cannot see."

Brant inspected the open groove. "We follow long enough to confirm direction. Vera stays second. Holt counts every branch. Tess calls staff hardware before I touch it. If a door closes behind us, we return immediately."

"And if the return closes first?" Holt asked.

"Then we stop calling it a trail and start calling it an ambush."

They entered in order.

The ceiling forced Brant to hunch over the hook. Rails ran between his boots, slick with old grease and fresh wood dust. Before each step he pressed the hook shaft against the stone ahead, testing for drop plates. Vera followed with the cased crystal in one hand and her field book in the other, sketching without touching. Holt marked branches and counted backward under his breath. Tess named a roller brake, chain pawl, staff bell, and rat-feed shutter from behind them.

The route showed Brackenvault’s working organs. Copper pipes sweated hot water onto their collars. Rat grates inhaled, drawing damp straw scent through side burrows. Thumb-sized doors snapped shut ahead of their lamp. A pale worker with too many elbows darted across one junction carrying a stiff brush and a bucket of black wax.

Tess whispered, "It has a cleaning shift."

No one answered. A rat shutter opened somewhere behind them and made the rails hum.

Brant raised a fist. They listened until the vibration faded, then continued.

Ahead, Dane recognized four sets of feet through the floor.

Brant came first, heel-heavy and measured. Vera followed with a pause after every few steps. Holt’s tread kept exact distance behind her. Tess favored the outside of one boot and now stayed farther back than usual.

The five coppers near Dane’s front rim trembled.

Moderate command pressure warmed the ownership nail at Vera’s approach. His assigned body read the approaching mage as pulse, throat, wrist, and bite angle. Dane used Cognition 5 to keep those predatory instructions separate from his own sequence.

Hurt first.

He anchored against the split left hinge. The spent resin bubble offered nothing; old damage supplied the pain.

Hold second.

The lid stayed beneath its inviting angle.

Move last.

One copper had edged toward shine with the vibration. His tongue pushed it dull-side up into the left pair. Two pairs and the diagonal center held near the gap, too deliberate for spilled money and too incomplete for language.

The service door ground open.

Brant entered the new room first and stopped before the chalkless threshold. He tested the first pace with the hook point, then the left and right edges. Above Dane, ceiling chains hung from a slab track. Three low grates faced the center. Straw-packed scent grooves ran from them around a bite-scarred pillar and beneath Dane’s front board.

"Found him," Holt said from the service groove, relief weakening that one word before fear restored his next breath.

Vera opened the crystal case. Clouded light folded around the wrong-side print and recoiled from Dane’s ownership nail.

The lid shuddered.

Brant put his forearm across Vera’s path. "My line ends here."

"Agreed."

She stayed behind it and studied the room before looking at Dane: slab track, chain anchors, grates, scent grooves, rails, then the mouth. The coppers caught her last.

The tarnished faces returned almost no lamplight.

"Those were arranged," Vera said.

Brant kept the hook raised. "Or the Core built bait that flatters your conclusion."

"Possible. Five shallow coins, all dull-side up. Two paired columns and one diagonal. The lure loses shine, and the pattern survives movement that cracked cured resin off his side."

Tess leaned just enough to see past Holt. "Dull on purpose. A collector would turn every face toward the gap."

"A warning?" Holt asked.

"Evidence of selection," Vera said. "Meaning remains unproved."

Dane held the split until pain traveled from hinge to lockplate. She had not called him safe. She had seen the choice without giving it a story.

The crystal’s print pressed outward. Vera crouched behind Brant’s line and angled the glass toward the coin pattern. The slab track above answered with a small chain tick.

Brant looked up. "Back."

Vera rose at once.

A side grate exhaled mage-scent into Dane’s room. His lid surged against the split, and the diagonal copper rolled a fraction. Vera saw the change.

"One bounded step left," she said. "If the coin follows me, trigger. If it returns dull, selected resistance."

"Denied. We know the room is active."

"Then we leave with bait as the stronger explanation and no route to challenge it."

Brant measured the left wall, the hook reach, and Vera’s retreat. "Half a step. My hand stays on your sleeve."

She accepted the condition.

Vera shifted along the wall rather than toward Dane. Brant kept two fingers locked in the fabric above her elbow. Her boot cleared the point his hook had tested and settled on a separate stone inset disguised by straw dust.

Click.

Dane heard the floor catch. Brant heard it through the hook shaft.

He yanked Vera backward as the ceiling released.

The slab fell between them.

Its lower edge struck Brant’s hook, drove the shaft from his hand, and showered sparks across the threshold. Vera tore free of his grip on the other side. Stone hit its floor channel hard enough to jump dust from every grate.

Brant seized the hook again and rammed its point into the seam. The slab held.

Holt shouted Vera’s name. Tess braced beside Brant without touching the mechanism she had failed to predict.

Inside, Vera backed to the left wall with her crystal raised.

She was alone with a predatory chest she had just called deliberate and a dungeon prepared to test the word.
