The Cost of Gauze

The brown glass bottle smelled like ditch water instead of sweet fennel, which meant someone had spent the morning thinning our surgical wash to stretch the Instituto's quarterly ledger.

I set the stopper on the warped deal table and watched the murky ring expand across the unvarnished grain. In the drafty west wing dormitory where the twelve of us had been quartered like stray horses, the midday chill had already settled into the floorstones. Eleven cots lined the far wall, each stripped down to horsehair ticking and thin wool blankets that smelled of sulfur and wet lime. Rafael stood near the high arched window, his arms folded across his chest, staring out toward the northern quadrangle where the Instituto's second-year vanguards were running kinetic drills with wooden practice rods.

"Is it salvageable?" Rafael asked without turning around.

"If our goal is to give Bernardo gangrene by breakfast, it is exceptional," I said.

I picked up the tally slate and marked another line through our inventory. The confiscation at the gate had cost us two full crates of surgical stock, but the real insult was what Professor Aranda's wardens had left behind. Out of forty rolls of woven cotton bandage, twenty-two were stained with iron mold. The carbolic wash had been diluted by half. The three jars of bone-setting plaster had seized into solid chalk during transport because the crates had been loaded onto an open cart in the rain.

And the silvered vitriol, the only stabilizing agent fast enough to knit shredded vascular lining before a kinetic charge could liquefy the surrounding flesh, was gone. Every drop of it had ended up under Aranda's riding boot on the threshold stones.

"We have nine ounces of willowbark tincture," I said, tapping the slate against my knuckle. "Six packets of powdered alum, forty yards of clean linen tape if I boil it twice, and five suture needles that haven't rusted through the eyelets yet. That gives our vanguard cohort exactly three minor lacerations and half a fractured collarbone before we are down to prayers and clean rags."

"Bernardo's fever is rising," Inma said from the corner cot. She was sitting cross-legged on her mattress, methodically sorting through a leather pouch of brass trade tokens and tallow candles. "I went down to the lower convalescent ward twenty minutes ago to bring him dry socks. The orderly wouldn't let me past the copper gate without a requisition slip signed by an Instituto proctor."

"How did he look through the grille?" I asked.

"Gray," Inma replied flatly. "Sweating through his tunic. The dressing on his thigh was seeping dark yellow fluid, not pink serum. If you don't flush that arterial channel with pure vitriol by nightfall, the clotting spell you laid at the gate will rot from the inside out."

My fingers moved to my apron pocket, finding the cold three-fluted needle I had pulled from Bernardo's leg. The metal was smoother than glass, ground down with terrifying precision so that it would punch through a ward and spin inside muscle without meeting resistance. Matias Valdivia had cast it from fifty yards away without breaking stride. A man who forged kinetic darts that clean did not make mistakes; he left warnings.

"Aranda knew exactly what he was crushing when he put his heel through my satchel," I said, setting the slate beside the ruined bottle. "He wants Bernardo to lose the leg. If our fastest vanguard spends the term hobbling on a hickory crutch, the Ouro cohort is already broken in half."

Rafael turned from the window, his jaw set hard. "I can take four swords down to the central courtyard. The exchange treaty guarantees us equal access to the standard armory and dispensary. They cannot deny a formal petition from an Ouro squad leader."

"They will not deny it," Inma said, not looking up from her brass tokens. "They will stamp your parchment three times, tell you the dispensary clerk is attending evening devotions, and file your requisition under 'miscellaneous foreign requests' until Bernardo is buried in the potter's field behind the chapel. You cannot intimidate a bureaucracy with a short sword, Rafael. It only gives them an excuse to double the guard at our door."

"Then what is your proposal, Suarez?" Rafael asked, his voice tightening.

Inma pointed a thumb at me. "She goes to the Lower Commissariat. Medics carry treaty status under the third annex. Even Aranda has to maintain the fiction of an administrative review if she demands an inspection of our damaged stores."

"The clerk will laugh at her," Rafael said.

"Let him laugh," I said, tying the canvas strings of my utility apron and grabbing my empty leather satchel. "A clerk only laughs until you show him what he signed."

·  ·  ·

The Lower Commissariat occupied a vaulted cellar beneath the western bastions of the Instituto, where the damp cold smelled of salted pork, damp coal, and old tallow. Low iron arches supported a ceiling encrusted with saltpeter, and the only light came from sputtering oil lamps hung every twenty paces along the corridor.

At the end of the hall, behind a heavy lattice of oak and iron bars, a clerk named Garrido sat at a high counting desk with three inkhorns and a stack of vellum ledgers. He was a round-shouldered man in a patched wool robe, his spectacles perched on the tip of a bulbous nose. When Inma and I stepped onto the stone flags before his wicket, he did not look up. He dipped a quill, scratched a line across a sheet of yellowed paper, and turned a page with deliberate slowness.

"Visiting students," Garrido muttered to the vellum. "Requisitions close at noon. Come back on Friday after the third bell."

"The third annex of the Sovereign Exchange Accord," I said, resting both hands on the iron ledge of the wicket, "states that medical stores damaged or seized during intake processing must be reconciled within six hours of arrival. We arrived at midday. It is now two in the afternoon."

Garrido's quill stopped mid-stroke. He lifted his head, his small gray eyes squinting at my gray-and-gold Ouro shoulder badge. A faint, oily smile crept across his mouth.

"Ah," he said. "The field medic. The one whose classmate had an unfortunate accident on the threshold. Professor Aranda already submitted the import assessment. Two crates of uncertified biologics were confiscated under the health safety ordinance. You were issued your standard baseline allowance."

"The baseline allowance is forty percent water and twenty percent mold," I replied evenly. "I need four vials of silvered vitriol, ten rolls of bleached surgical linen, and a box of tempered suture needles."

"Vitriol is a controlled alchemical reagent," Garrido said, waving a limp hand as if brushing away a fly. "Class three combatants only. Visiting students are not cleared for high-purity catalysts until the second semester, pending a disciplinary review."

"Bernardo Vega has an open arterial puncture," I said. "Without silvered vitriol to neutralize the kinetic residue, the wound will suppurate before tomorrow morning. That is not a disciplinary matter. That is manslaughter under treaty oversight."

"Then I suggest you pray for his constitution, Señorita Flores," Garrido said, leaning forward until his breath smelled of sour wine and pickled cabbage. "This is the Instituto del Cobre. We do not waste military-grade reagents on careless boys who cannot hold their wards at the front gate."

Inma stepped up beside me, leaning her shoulder against the iron wicket. "Garrido," she said in a low, conversational tone. "Your sister's boy is still apprenticed to the copper-smiths in the lower quarter, isn't he? The ones who buy their flux through the Ouro border merchants?"

Garrido stiffened, his fingers curling around his quill. "Are you threatening an officer of the stores, girl?"

"I am observing the weather," Inma replied cheerfully. "Flux prices are terribly volatile when trade routes get complicated. But Cata here isn't asking for flux. She is asking for what the treaty specifies on page fourteen."

Garrido sneered, reached beneath his desk, and slammed a wooden tray onto the shelf between the bars. "Fine. Your treaty ration. Take it and clear the corridor before I call the bastion wardens."

On the tray sat three small stoneware jars sealed with wax and a rough bundle of gray cloth tied with hemp twine.

I did not touch the cloth. I picked up the first stoneware jar, broke the wax seal with my thumbnail, and held the mouth of the vessel beneath my nose. The pungent sting of vinegar hit first, followed by a sharp, metallic tang that made the back of my throat contract.

I reached over, plucked the blackened iron bodkin from Inma's hair, and dipped the blunt tip into the liquid. When I pulled it out and held it up to the oil lamp, the surface of the iron had turned a dull, mottled salmon pink.

"Copper sulfate," I said, looking Garrido dead in the eye. "You took standard vinegar, dumped in blue vitriol crystals to fake the color of silvered astringent, and topped it with ditch water. If I pour this into Bernardo's wound, the copper will bond with the kinetic residue and corrode his femoral wall in twenty minutes."

Garrido's face lost its smug slackness. "That is the standard tincture from the depot vats—"

"It is poison," I interrupted, keeping my voice cold and steady. "And you know it. An apprentice alchemist knows copper sulfate plates out on iron. Do you want me to carry this jar directly up the central stair to Arch-Chancellor Vane's chambers? I am sure the council would love to know that the Lower Commissariat is cutting military stores with mining runoff and charging the crown for pure vitriol."

Garrido swallowed hard, his Adam's apple bobbing above his woolen collar. For three seconds, the cellar was utterly silent except for the hiss of the oil lamp.

"A mistake," Garrido muttered, his knuckles whitening as he dragged the wooden tray back through the wicket. "A new batch from the lower vats. Untested."

"I do not care what vat it came from," I said, leaning closer to the bars. "Give me clean surgical steel needles. Give me four rolls of double-washed linen. And give me half a jar of pure carbolic paste, or I will stand in the middle of the quadrangle at the change of watch and demonstrate this titration on my bodkin for every passing squad."

Garrido did not argue. He turned around, unlocked a small iron-bound cupboard behind his desk, and pulled out a flat tin box and a sealed glass jar of dark carbolic ointment. He slammed them onto the ledge alongside four tightly bound bundles of bleached bandage.

"Take them," he hissed, his face dark with suppressed fury. "And do not come back to this window again."

"We will be back on Friday," Inma said with a bright smile. "Have the good linen ready, Garrido."

·  ·  ·

I packed the needles, the bandages, and the carbolic paste into my satchel, fastening the brass buckles with deliberate care as we walked away from the depot. The weight against my hip was a relief, but the victory tasted like ash in my mouth.

"We got the steel and the linen," I said as we ascended the narrow stone stairs toward the upper cloisters. "But we still do not have the vitriol. Without it, the carbolic is only buying Bernardo another twelve hours."

Inma glanced behind us, checking the shadows between the vaulted buttresses before catching my elbow and pulling me into the alcove beneath a marble statue of some long-dead Cobre grandmaster. The stone alcove smelled of damp moss and old incense.

"You pushed him as far as he could go without calling the guards," Inma said in a hushed whisper. "Garrido doesn't have pure vitriol in those cupboards anyway. None of the depot clerks do."

I frowned. "What do you mean?"

"The administration locked all high-grade reagents in the upper vault three days before we arrived," Inma said, her dark eyes narrowing. "I talked to one of the scullery runners while you were arguing at the gate. Aranda issued a directive. The Ouro cohort is on a restricted medical quota by executive order. They aren't just skimming supplies for profit, Cata. They are running a deliberate attrition protocol."

A cold weight settled in my gut. "They want us to bleed out in the training rings."

"They want three of our vanguards crippled and sent home on a wagon before the first month ends," Inma corrected. "That gives the Instituto political leverage to claim Ouro's combat standards are defective, while keeping the exchange legally compliant. They don't have to murder us in our beds. They just have to let simple dueling wounds turn septic."

I looked down at the satchel at my side. Eleven students left in our wing. Rafael was proud, Bernardo was already incapacitated, and the rest were eighteen-year-olds who thought their shield charms could stop anything. If an infection took hold in our dorm, I would be burying classmates before the autumn rains turned to sleet.

"There has to be another source," I said. "The Instituto's senior duelists use vitriol after every match. Where do they get it when the dispensary is closed?"

"From the pits," Inma said simply.

I stared at her. "The sub-vaults?"

"The old foundry beneath the lower barracks," she said, leaning closer until her voice was barely a murmur against the damp stone. "The faculty pretends it doesn't exist, but every squad leader from the second year up wagers their stipend down there. Unsanctioned duels, real kinetic charges, no proctors to call a halt on first blood. When someone gets opened up, they can't go to the hospital ward without getting an official reprimand on their record. So the pit masters buy pure alchemical supplies on the black market to patch up their fighters."

"And who runs the pit stores?"

"A broker named Tadeo," Inma replied. "He owes me three favors from a flux shipment last winter. I sent a runner to his workshop while you were packing your kit this morning."

As if summoned by her words, the soft scrape of leather boots sounded against the flagstones at the edge of the colonnade.

A young man stepped into the shadows of the alcove. He wore the dark green tunic of the Instituto's artisan guild, his sleeves rolled up to the elbows to reveal forearms crosshatched with minor acid burns. A heavy brass ring hung from a cord around his neck, stamped with the insignia of a smelting crucible.

"Inma," he said, nodding once. His gaze flicked over me, taking in the satchel and the Ouro badge with frank assessment. "This is the medic who stopped the femoral bleed at the gate?"

"Catalina Flores," Inma said. "Cata, this is Tadeo. He handles the requisitions that never make it into Garrido's ledgers."

"I hear you know how to clamp an artery under kinetic fire," Tadeo said, his voice quiet and practical. "And I hear your friend down in the lower ward is about eight hours away from losing his thigh to gangrene."

"I need three ounces of silvered vitriol," I said, skipping the pleasantries. "Pure grade, ninety-five percent minimum. Name your price."

Tadeo gave a dry, humorless chuckle. "Gold is useless down here, Flores. Everyone has gold. What we don't have is a field surgeon who can seal a kinetic tear without leaving an ether signature that the wardens can track."

"What are you asking?"

"Midnight," Tadeo said, reaching into his pocket and pulling out a small, flat token made of tarnished red copper. He held it out between two fingers. It was stamped with an open eye surrounded by five kinetic needles. "The sub-vault beneath the old blast furnace. We have a three-card challenge match tonight between the second-year champions. The main card is heavy kinetic, no damping wards."

My pulse jumped. "Who is on the main card?"

Tadeo's mouth twitched into a sharp, lopsided smile. "Matias Valdivia."

The name hung in the damp air between us, heavy and cold. My hand tightened on the strap of my satchel.

"Valdivia doesn't fight in student brawls," I said. "He is the star vanguard of the Instituto. Aranda treats him like a royal prince."

"Aranda uses him like an iron hammer," Tadeo countered. "And even hammers need to keep their edges sharp where the proctors can't watch. Valdivia took a private challenge from our third-year dueling master. It's an honor match with full kinetic loads. Someone is going to get shredded, and the pit master will not allow a corpse on the floor to draw the provost's watch."

"And you want me to be the butcher who cleans up the mess," I said.

"I want a medic who doesn't panic when the blood hits the stone," Tadeo said. "You stand at the edge of the pit. If someone takes an internal bleed, you stabilize them on-site, off the record. In exchange, I put three sealed vials of pure military vitriol into your hands before the first strike is cast. Enough to cure your boy Bernardo and keep your entire cohort patched for the next three weeks."

I looked at the copper token resting in his palm.

Taking it was madness. If the faculty wardens raided the sub-vaults, an Ouro exchange student caught at an illegal blood match would face immediate expulsion or a sentence in the penal quarries. Rafael would tell me to refuse. Bernardo would rather lose his leg than have me risk my neck for Cobre duelists.

But Bernardo was burning with fever three floors below us, and tomorrow morning another Ouro student would be shoved into the training quadrangle with watered-down carbolic in our kit.

"Three vials," I said, meeting Tadeo's eyes. "Unopened, sealed with the silver sovereign wax. I inspect them before I touch a single needle to any of your fighters."

"Done," Tadeo said, dropping the heavy copper token into my outstretched palm.

The metal was freezing against my skin, its stamped edges biting into my fingers.

"Midnight," Tadeo whispered, stepping back into the shadow of the colonnade. "Third door past the old coal chute. Do not bring a lantern."

He turned and melted into the gloom of the cloister, leaving Inma and me alone beneath the cold stare of the marble grandmaster.

"You're out of your mind," Inma said softly, though there was no real surprise in her voice.

I closed my fingers around the token, feeling the hard press of the open eye against my palm.

"I have four hours to sharpen my needles," I said. "Let's go boil the linen."
