Scavenging the South Wing

The iron bolt outside my door weighs at least four pounds.

I know the weight because I heard the drop. Heavy forged bar, greased track, double latch. Rebato chose the cell well. A guest suite on the third tier of the east wing sounds like an honor until you count the locks.

Four guards stand in the corridor. Their boots scrape the slate at twenty-second intervals. Two paces left, pivot, two paces right.

Standard Mokude sentry cadence. Predictable. Dull.

I sit on the edge of the low timber bed frame, waiting for the oil lamp on the side table to gutter. The cedar wick sputters, drinks the last pool of fat, and dies with a thin ribbon of bitter smoke.

Darkness drops over the room like a wool blanket.

My eyes adjust in ten breaths. Scavengers learn to see in the dark before they learn to walk the sorting pits. When your family lives off the slag heaps of the Hiraga border, light is a luxury that draws tax collectors and raiders.

I stand up. The floorboards are dry mountain pine, pegged rather than nailed. They groan if you put weight on the center of the plank. I keep my feet over the joists, three inches from the wall baseboard.

Silence. Not a creak.

I reach into the waistband of my linen trousers and pull out Nokuto's notched bone token.

The carved marrow is three inches long, tapered at the end where my brother ground it down against a river whetstone. It looks like an ornamental toggle for a tobacco pouch. It is actually a hardened lever.

I walk to the northeast corner of the bedchamber, beneath the high ceiling beam.

The ventilation shaft sits eight feet off the floor, masked by an ornamental iron grate. The Mokude love their geometric lattice work: interlocking hexagons cast in grey pig iron. It looks decorative, but it feeds fresh mountain air into the inner keep from the high windward battlements.

Two slotted iron screws hold the bottom corners of the grate to the timber frame.

I drag the bedside stool across the rug, lifting it clean off the floor to avoid dragging the feet. I step up onto the seat.

The air hitting my face smells of frost, chimney soot, and damp stone. Deeper down, carried on the undercurrent, is the sharp sulfuric tang of black powder.

The powder cache is real. It sits somewhere in the guts of this fortress.

I slide the tapered edge of Nokuto's bone token into the slot of the left screw.

Rusted iron resists. The threads bite hard into the seasoned oak. I do not force it. If the bone snaps, I lose my only tool. If the screw strips, I am trapped in this bridal cage until Sashiro decides which part of me to interrogate next.

I lean my shoulder against the wall, wedge the token at a thirty-degree angle, and apply steady, rhythmic pressure.

Creak.

A micro-fraction of an inch. Rust flakes dust my knuckles.

I turn it another quarter stroke. The threads give way. Three slow turns, and the screw drops cleanly into my left palm. I slip it into my trouser pocket.

The second screw is looser. Five turns with the bone lever, and the iron plate tilts forward on its top hinges.

The opening is eighteen inches wide and fourteen inches high.

Narrow. Tight. Built for smoke and draft, not for an adult body.

A grown Mokude soldier with broad shoulders and plate armor would jam at the collarbones. A Hiraga scavenger who spent three years crawling through the collapsed ventilation flues of the Takamine ironworks can fit with two inches to spare.

I grip the lower lip of the stone shaft.

The stone is rough basalt, mortar crumbling at the joints. I haul myself upward, pulling with my forearms and digging the toes of my linen slippers into the timber trim.

My hips clear the frame. I slide into the shaft on my stomach.

The air inside is cold and thick with centuries of dried soot. It coats my mouth instantly, dry and bitter like burnt barley.

I reach backward with one hand, catch the iron grate, and pull it back against the frame. I replace the lower screws with two small balls of grey wax scavenged from the dead lamp on the nightstand. To a guard glancing up from the doorway, the grate looks firmly fastened.

I turn onto my chest and begin to crawl.

·  ·  ·

A stone fortress is not a solid block of rock. It is a breathing lung.

Air enters through high battlements, draws down through vertical shafts, heats across hearths and forge flues, and vents out the high chimneys. If you know the lungs of a fortress, you know every room it feeds.

The shaft slopes upward at five degrees.

I move on elbows and knees, keeping my weight distributed flat. Every movement kicks up clouds of fine black dust. It gets into my eyelashes, under my fingernails, between my teeth.

After twenty yards, the single shaft intersects a three-way junction.

The air changes here.

To the left, the draft is warm and smells of roasted duck, boiled cabbage, and greasy dishwater. The main kitchen flues.

Straight ahead, the shaft drops vertically into a dark vertical drop with iron rungs mortared into the rock. That leads down to the central barracks and the armory.

To the right, the shaft narrows into a dark horizontal tunnel that slopes downward toward the south wing. The air coming from that tunnel is freezing cold, smelling of stale water, mold, and dry limestone.

Third cistern, Nokuto had whispered. Behind the collapsed smoke duct.

I turn right.

The shaft here is older. The stones are uncut river boulders held together with coarse lime mortar. In some spots, tree roots from the mountain slope above have cracked through the masonry, hanging down like dry webs.

My shoulder scrapes a jagged edge of slate.

Pain flares across my skin, sharp and hot. I stop. I press my forehead against the cold floor of the shaft until the tremor in my shoulders passes.

A wedding night in the great house of Mokude.

Most highborn brides are currently untying silk sashes, drinking spiced plum wine, and pretending not to dread their new husbands. I am crawling through a rat-choked chimney shaft in my underwear, coated in soot, hunting for dead men's weapons.

Nokuto would have laughed. He had a dry, barking laugh that used to echo off the iron scraps in the sorting yard.

You always picked the hardest ditch, Tomi, he would say.

I push forward another ten yards.

The tunnel widens into a square masonry chamber where four ventilation ducts meet around a central chimney flue. In the center of the chamber, an iron damper plate hangs suspended by a heavy counterweight cable.

The mechanism is jammed.

A massive iron plate, three feet square and two inches thick, hangs at a precarious tilt directly over the south conduit. It looks like an ordinary chimney baffle meant to block winter drafts.

Something about the angle is wrong.

The counterweight cable does not run to a wall winch. It loops around a rusted pulley and anchors directly into the floor mortar beneath a sheared iron pin.

I reach out my right hand.

My fingertips brush the broken iron shear-pin sticking out of the floor socket.

The Trace wakes with a jolt.

My skull rings like a struck anvil. The copper taste hits the back of my tongue.

A memory tears through my vision:

Ten years ago. Mokude masons in leather aprons hammering iron pins into the rock.

They are not building an air shaft. They are rigging a deadfall.

A heavy tripwire made of braided horsehair runs across the lip of the south conduit. If a human shoulder hits the wire, the shear-pin snaps completely. The four-hundred-pound damper plate drops like a guillotine, sealing the shaft and crushing whatever is beneath it into paste.

The vision snaps shut.

I pull my hand back, my palm sweating against the cold basalt.

My nose begins to run. I wipe it with the sleeve of my linen shirt. A thin streak of crimson stains the grey fabric.

The Trace is taking its tax. Every reading tears a little more lining out of my head.

I look at the floor of the shaft.

Two inches ahead of my knees, half-buried under a layer of accumulated soot and rat droppings, is the dark strand of braided horsehair.

It is taut. One careless kick of my toe would have dropped four hundred pounds of solid iron onto my spine.

"Charming builders," I murmur under my breath.

I flatten myself against the left wall of the masonry chamber. Carefully, inch by inch, I lift my right leg over the tripwire, planting my knee on the solid flagstone on the other side. Then I drag my left leg through, keeping my hips pressed against the rough side wall.

The horsehair wire does not twitch. The iron damper plate stays suspended in the dark.

I let out the breath I was holding and slip into the south conduit.

·  ·  ·

The south conduit drops steeply downward toward the mountain bedrock.

Here, the air grows damp. Condensation slicks the walls, turning the soot into black grease that smears across my arms and thighs. The temperature plummets until my breath plumps out in white clouds against the stone.

I count the vertical drops.

One. The second-tier guest quarters.

Two. The guard mess hall. I can hear the muffled thump of wooden tankards hitting trestle tables below, accompanied by rough laughter and the scrape of benches.

Three. The cistern level.

The draft here dies completely. The air is heavy, still, and reeks of stagnant mineral water and old lime.

I reach a dead end where the stone conduit terminates against a collapsed brick wall.

This was once a secondary smoke flue for a smithy forge that burned out fifty years ago. The bricks are blackened, crumbling, and choked with dry mortar rubble.

I pull Nokuto's bone token from my pocket.

Three notches.

I count three courses of brick down from the ceiling vault.

The mortar in the third course is not ancient lime. It is grey clay mixed with ash—a quick-setting patching paste Hiraga scouts use to conceal supply drops in the field.

I dig the tapered point of the bone token into the seam.

The clay flakes away easily, soft and crumbly compared to the hard mountain stone. Within three minutes, I have carved out an eight-inch square opening.

I reach my arm into the dark cavity behind the bricks.

My fingers brush against cold, greasy oilskin.

My pulse jumps.

I wrap my hand around the bundle and pull it out into the shaft.

The package is the size of a small cedar box, wrapped in three layers of heavy oiled sheepskin and bound with waxed hemp cord.

I use the edge of the bone token to saw through the cord.

I unwrap the leather folds.

Inside sits a narrow wooden box carved from red camellia wood. Inside the box, nestled in dry wood shavings, is a single glass vial sealed with green beeswax, and a rolled strip of oiled parchment.

I pick up the vial.

The liquid inside is pitch black, thick as treacle. When I tilt the glass, a faint emerald iridescence clings to the inner walls.

Kuro-hebi. Black viper bile distilled with mountain nightshade.

The signature poison of the Hiraga border scouts. It has no taste, no smell, and leaves no discoloration on silver. Two drops in a cup of wine will seize the heart muscles within forty heartbeats.

A slow, terrifying death that mimics sudden apoplexy.

Nokuto did not leave black powder here. He left the key to a quiet murder.

Beside the vial, the rolled parchment crinkles in my fingers. I unroll it against my knee.

It is a hand-drawn map of the Kashiro compound's sublevels, sketched in charcoal by Nokuto's own hand.

My brother's handwriting is unmistakable: sharp, angular strokes, hurried and precise.

He mapped the drainage sluices beneath the central courtyard, the secret tunnels connecting the inner keep to the lower stables, and a single red circle marked deep beneath the third cistern.

The Arsenal.

Written beneath the circle are three words in the Hiraga cipher:

Forty barrels. Powder.

I stare at the map.

The powder is here. Nokuto found it before the Mokude killed him. It sits four levels beneath my feet, locked behind the heavy iron sluice gates of the lower reservoir.

I roll the parchment tight and slide it into the hollow bamboo tube stitched into the lining of my trouser waistband. I take the vial of poison and wrap it in a scrap of oiled cloth, securing it against my ribs beneath my sash.

The weight of the vial against my skin is cold, but it brings a vicious, steadying calm.

I am not just a hostage anymore. I am an armed threat inside their walls.

·  ·  ·

I repack the empty camellia box with loose mortar rubble, slide it back into the wall cavity, and plaster the opening with leftover clay paste.

To an untrained eye, the brickwork looks undisturbed.

I turn around in the narrow shaft and begin the crawl back.

Moving against the draft is slower. My shoulders burn with exhaustion, and the scrapes along my ribs throb with every inch I drag myself forward. The twelve-pound bridal gown from earlier had already drained my legs; now my upper arms feel like lead weights.

I reach the junction above the south guardroom.

A warm, flickering glow filters up through an iron floor grate directly beneath the conduit floor.

Voices drift up through the slats.

I freeze, flattening myself against the soot-stained stone.

"He put her in the east wing," a voice says.

Rebato.

His rough, guttural voice is unmistakable. It grates like two river stones grinding together.

I slide forward half an inch, peering down through the diamond-shaped openings of the iron grate.

The room below is the inner watch office. A charcoal brazier glows red in the center of the flagstone floor. Maps of the mountain perimeter are pinned to the timber walls with iron spikes.

Rebato sits at a heavy trestle table, nursing a steaming bowl of bitter barley tea. His scarred skull gleams in the brazier light, the jagged white line running from his ear to his crown looking like a jagged lightning bolt.

Two Mokude senior retainers stand before him, their hands resting on the hilts of their curved blades.

"Lord Sashiro claims she has value," one of the retainers says. "He told the council she read the siege engine failure at Takamine."

Rebato spits into the brazier. The spit sizzles and evaporates in a puff of white smoke.

"Sashiro is blinded by her parlor tricks," Rebato growls. "The girl is Hiraga vermin. Her brother was the one who mapped our outer trench lines before the spring assault. You think she came here for peace?"

"The treaty mandates the marriage, Commander," the second retainer says. "The elders signed the pact at the border. If the bride dies before the registry is sealed, the southern clans will declare a breach. We will have forty thousand spearmen in the gorge before the snow melts."

"The bride does not need to die tonight," Rebato says, his voice dropping into a sinister murmur.

I hold my breath. My fingernails dig into the stone floor of the air shaft.

Rebato leans forward across the table, his scarred face twisting into a cruel, calculating grin.

"The banquet is set for tomorrow night in the Great Hall," Rebato says. "Sashiro wants a formal show of unity. He ordered the forty Hiraga attendants brought up from the lower holding pens to serve the wine."

"And?"

"And accidents happen in old fortresses," Rebato says.

He taps the edge of his tea bowl with a heavy iron ring.

"At midnight, before the banquet concludes, my boys will breach the east storehouse beneath the servant quarters. A barrel of pitch. A dropped torch. The fire will sweep the lower barracks in three minutes."

The retainers exchange a glance.

"The Hiraga retinue?" one asks.

"Locked from the outside," Rebato says coldly. "Forty Hiraga dogs burned to ash in their sleep. When the smoke clears, we tell Sashiro the attendants tried to set fire to the powder store and blew themselves up. The treaty remains intact, the bride is isolated without a single ally inside the walls, and the Hiraga vermin are purged."

My blood turns to ice.

Forty people.

Yumika is in those holding pens. The craftsmen, the weavers, the young grooms who escorted my litter across the gorge—every single one of them will be burned alive in the dark while Rebato bars the iron doors.

"What about the bride?" the second retainer asks. "If she suspects—"

"If she opens her mouth, I will break her neck myself," Rebato says, standing up from the table. "Sashiro thinks he can tame a scavenger. I know better. A viper is a viper until you crush its skull."

He picks up his heavy iron cleaver from the table and slides it into his belt.

"Set the pitch barrels at tenth bell tomorrow night," Rebato orders. "Not a word to Lord Sashiro. If he asks, we were reinforcing the east wall."

"Understood, Commander."

The two retainers bow and exit the room, their heavy boots echoing down the stone corridor.

Rebato lingers for three heartbeats by the brazier. He stares into the red coals, his thumb tracing the jagged scar on his skull.

Then he turns, blows out the single oil lantern on the table, and walks out into the hall.

The heavy door thuds shut.

Silence returns to the guardroom.

·  ·  ·

I lie in the darkness of the air shaft, my chest heaving against the cold stone.

My ribs ache. My knees are raw and bleeding through my trousers. The soot in my throat feels like crushed glass.

Midnight tomorrow.

Rebato is going to butcher my entire retinue.

If I go to Sashiro, what will I say? I heard your commander plotting treason while I was illegally crawling through your air shafts with a vial of poison in my shirt.

Sashiro would slit my throat before I finished the sentence. Even if he hates Rebato for Kisa's murder, he will not accept intelligence from a scavenger bride who violated his fortress security on her wedding night.

I cannot run to Sashiro.

I cannot fight Rebato's men with iron.

I touch the small, hard shape of the poison vial pressed against my ribs.

Kuro-hebi.

Nokuto left me the poison to bleed the Mokude dry.

Tomorrow night, at the Great Hall banquet, I am going to use it.

Not on Sashiro.

On Rebato.

I back away from the grate, inching backward through the dark shaft toward the east wing.

The hunt has begun.

·  ·  ·

I drop through the ceiling vent into my bedchamber with the silence of falling snow.

My bare feet hit the floorboards directly over the joist. Not a single creak.

I turn around, push the iron grate back into the timber frame, and secure the lower corners with the two balls of grey wax. The fit is snug. In the darkness, nobody could tell the screws are missing.

I walk to the washstand in the corner of the room.

The ceramic basin holds cold well water. I dip a linen towel into the basin and begin scrubbing the soot from my skin.

Black water runs off my forearms, my neck, my collarbones. I wash away the grime until my skin is raw and red, scrubbing every trace of the ventilation shaft from under my fingernails.

I take Nokuto's map and the vial of poison and conceal them inside the hollow cedar base of the heavy wardrobe behind the bed.

Then I pull on a clean linen robe, climb onto the hard timber platform, and pull the coarse wool blanket up to my chin.

Outside, the sentries pace their twenty-second cadence.

Two paces left. Pivot. Two paces right.

The first grey light of dawn begins to bleed through the vertical slit window, painting thin stripes of silver across the cedar floor.

I close my eyes.

I do not sleep.

I lie in the cold light, listening to the fortress breathe, and wait for the wolves to wake.
