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

The slab rose with stone dust pouring from its teeth.

Brant came under it as soon as the gap cleared his shield. He entered low, hook raised over the shield rim and eyes fixed on Dane’s lockplate. Holt followed on Brant’s left with his prayer cord looped around two fingers. Tess slipped through last, knife out, and turned toward the service latch before the slab had finished grinding overhead.

They had entered ready to recover a body.

Vera stood three paces from Dane with a torn strip hanging from her outer sleeve. Rust scored her bracer. The skin beneath both remained whole, and the ward crystal in her fist still held a low blue glow.

"Hold," she said.

Brant held because the order came before his relief could become motion. His hook point stopped above Dane’s front hinge.

The room showed what had happened. Blue flare residue stained the floor around the pillar, displaced straw exposed two scent grooves, and a fallen chain crossed them. The patrol leader’s short sword rested in the third groove; his knife lay by the dusty latch. A chipped cleaver remained buried in the far wall.

The left latch jumped once. Tess faced it with her knife ready while Brant put his shield between Vera and the wall. Overhead, Holt tracked the ceiling mechanism for another drop.

"Three left alive," Vera said. "The tunnel may bring them back. Clear the blades and keep the exit open."

Brant hooked the short sword by its guard and dragged it across the stone without lowering his shield. Tess pinned the flat with her boot, nudged it behind the rising slab, and returned to the latch. The skinning knife followed. For the cleaver, Brant caught the haft with the hook while Tess hauled the fallen chain clear of the grooves. One pull freed the blade from the wall. It struck the floor hard enough to make Dane’s lid twitch.

Brant turned the hook toward him.

"That movement was the room," Vera said. "He held through the patrol."

"Running kept the patrol alive," Brant answered. "I still count the chest as hunger with poor reach."

"Agreed. Nobody touches it. Nobody opens it, kicks it, blesses it, or feeds it anything with a pulse. We clear our route, test what happened, and leave before the room changes terms."

Holt moved to the slab channel and held his cord near the stone without laying it down. "No prayer line unless ordered. If the ownership route takes blessings as commands, I will not hand it another handle."

Tess lowered her knife enough to show she had heard. Her attention remained on the latch hinges and the dark tunnel beyond them.

Brant dragged the cleaver to the threshold. "You have until that wall moves again. Then I break the front hinge and accept the consequences while they are still smaller than a funeral."

The command mark in Dane’s lockplate warmed at the word break. Moderate pressure stirred his tongue beneath the five dull coins and laid a single target across the room: Vera’s wand wrist, three paces away, exposed where the torn sleeve moved.

The mark wanted him to open.

Dane set pain into the split hinge and kept the lid below the bite line. Cognition held the command target apart from the room’s actual positions: Brant behind a shield, Holt at the channel, Tess guarding the latch, and Vera fixed on the chalk arc. The predatory outline faded before his lid moved.

Vera studied the patrol marks while Brant watched Dane. The scuffs ran from the right grate along the wall, crossed behind the pillar, and crowded around the left latch. A dark arc on the floor showed where the fallen chain had swept through ward light. None of the tracks crossed into Dane’s cleanest bite groove.

The debris distinguished the three attackers better than their retreat had. A narrow heel cut marked the leader’s rush. Paired dents followed the hook-pole along the pillar base. The cleaver fighter had crushed whole patches of straw under broader boots. At the latch, every heel gouge pointed out into the tunnel. They had fled under their own power, but the fresh lever scratches on the frame said they knew how to open it again.

Vera traced the evidence with her crystal light, never her fingers. "We have minutes at most."

"They worked the right side first," Brant said.

"Then entered here." Vera indicated the dusty latch without touching it. "The first creak traveled through the ring beneath his left side. I heard it from this wall."

Brant’s jaw tightened. "Old rooms carry noise. A chain moved under a bad hinge, and three goblins panicked."

"That remains possible."

Her answer denied him an argument and kept the rival cause alive.

Holt looked from the right grate to the latch. "Then test location, not intention."

Vera gave him one nod.

She crouched on the same three-pace arc and drew a chalk line between the right grate and the left latch. A short crossbar marked the chain ring under Dane’s base. The test existed only on those three pieces of hardware and the path connecting them.

Brant planted himself outside her right shoulder. His shield covered the grate; the hook remained high enough to reach Dane’s split hinge. Holt stayed at the slab channel, watching the chalk and the ceiling track together. Tess took the left wall, far enough from the latch to see a goblin before it could clear the opening.

Vera closed her fingers around the crystal. "Right grate first."

She followed the chalk arc without reducing the distance between herself and Dane. Her boot stopped beside the grate. She lowered two fingers until they hovered above the iron bars.

The room pushed.

RIGHT SOUND. DRIVE MAGE LEFT. OPEN WHEN SHE CROSSES.

Dane felt the new Sound Lure route waiting beneath the command. The inner rim could pass vibration to wood, wood to the split hinge, and the under-base ring into any connected hardware. One copper already rested close enough for his tongue to use.

A creak from the grate would move Vera away from it. The room had taught him exactly where that retreat ended.

He left the copper still.

Nothing answered her hand.

Rat scent breathed through the disturbed straw while water struck somewhere inside the tunnel. Brant held the hook level.

Vera waited through three breaths, withdrew her hand, and returned along the same arc.

She put a chalk stroke on the dusty latch.

"Left latch."

Dane anchored in the split hinge. His lid stayed shut. His tongue pressed the nearest dull copper against the inner rim and carried one small vibration through wood, hinge, under-base ring, and ceiling loop.

The creak came out beneath Vera’s chalk.

Holt leaned forward to catch the quiet end. Exact direction made volume unnecessary: silence held at the right grate, the ceiling chains barely trembled, and the left latch complained once.

Vera stepped back to her original place.

Brant shifted the hook from Dane’s hinge to the space between the chest and Vera. He had not lowered it. He had changed what it guarded.

Holt loosened one turn of prayer cord around his fingers. "The room offered two answers. He selected one."

"Or the left path carries better," Brant said.

"Then it carries better when asked," Vera replied. "That is enough to change our procedure. It is not enough to call him safe."

Tess glanced at the short sword beyond the threshold, then at Vera’s marks. Her mouth opened on a price and closed again.

The System opened behind Dane’s sight.

/==[ Brackenvault Registry: Intelligence Review ]==\

| Trigger: Mage Inquiry / Sound Response

| Behavior: Pattern Selection

| Threat: Asset Reclassification

| Witnesses: Party Unit / Four

| Staff Action: Containment Pricing

\==[ Thought: No Longer A Maintenance Fault ]==/

Sound Lure had let him answer. The Registry had watched the same answer become a price.

A further answer could use the five coppers or point a creak toward Brant’s hook, Holt’s cord, then Vera’s chalk. Repetition could turn selection into crude vocabulary and prove that a mind stood behind the hardware.

It would also give Brackenvault a cleaner inventory of his mind.

The Registry had not rewarded communication. It had priced the number of people who witnessed it. A better answer now would teach the Core how much attention he understood, which object he distinguished, and how cheaply another owner might buy cooperation.

He kept every coin still as the left service latch rattled again. Brant’s shield rose. Tess kicked the three goblin blades into the hall, Holt checked the slab channel, and Vera closed her chalk before backing along the cleared line.

"We leave it alive," she said. "Breaking it may activate the room, and we do not know whether the bite order belongs to the chest, the ownership mark, or both. It selected location under a bounded test. It also held an open mouth above a goblin’s neck. Those facts earn containment and review. They do not earn trust."

Brant kept his shield toward Dane. "If the guild calls containment a rope and tells me to take the other end, I am cutting it."

"Put that objection in Holt’s record."

"Already there," Holt said. "Along with the strike threshold."

Tess sheathed her knife only after the latch fell quiet. "Restricted intelligence, three abandoned weapons, and a room trying to assist murder. The paperwork will arrive wearing boots and charge us for the leather."

It was the only joke anyone allowed. Nobody laughed.

Vera set the ward crystal near her heel. Its light made a narrow blue line across the chalk path without touching Dane. "We report a responsive hazard, hardware-borne sound selection, active ownership pressure, and an unresolved command source. No claim of speech. No claim of personhood. No claim of safety."

"And no price," Brant said, looking at Tess.

Tess’s mouth tightened. "No price in the report."

Tess had agreed only to the report. Brant accepted that narrow term long enough to move.

Holt crossed first with the goblin weapons. Tess followed, watching the left latch until the wall took it from view. Vera reached the threshold and stopped.

She remained three paces from Dane.

"I am not your owner, and I am not your food," she said. "If any part of you understands that, keep your lid shut until we leave."

Dane held the lid shut while she stepped beneath the slab. The ownership mark urged him to show coin, tongue, tooth, anything that would call the mage back. Containment pricing urged a different performance: valuable, responsive, recoverable.

He refused both.

Brant backed out last with shield and hook covering the gap. The slab descended. Blue light thinned across the floor, caught the chalk by the service latch, and vanished when stone met stone.
