The wind off the Caldera Waste always tasted of sulfur and shaved hair, but on the morning the beast died of pride, it tasted mostly of cheap copper.

Bram stood thirty feet in the air on an unplaned spruce gantry, balancing on the balls of his boots while holding a notched measuring pole against the swelling ridge of a war-mammoth’s spine. Below him, three apprentices held the stabilizing tethers, their knuckles white against greasy hemp. Down on the slush-covered cobbles of the yard, Master Haddon, the chief harnessmaker for the Grand Scribe’s logistics guild, was shouting about delivery deadlines and the glory of the Thrice-Crowned King. Bram ignored him. A man who shouts while standing near four tons of irritated muscle is either an inspector from the capital or a fool who has never had to scrape a shattered rib out of an ox-hide lining.

"Hold the pole plumb, Bram, by the gods," Haddon yelled, his fox-fur collar trembling in the draft. "We do not have three days to calibrate the wither-girth. The Lord Scribe moves his corps toward the Pale Trench before the new moon, and if this bull is not trussed and plated by dusk tomorrow, I’ll have the Guild Warden look into your timber allotments."

Bram did not look down. He pressed his thumb against the notched elderwood rod, sighting past the dense, grease-stiffened winter wool to find the actual line of the shoulder blade. A bull mammoth in musth was three-quarters deceit. The shaggy over-hair stood six inches off the pelt, puffed out by rage and moisture, and an apprentice who fitted a tree-frame to the beast’s silhouette rather than its skeleton would find the entire howdah rolling into the animal's belly the first time it wheeled to gore a siege-engine.

"He’s hollow behind the left scapula," Bram said, his voice flat and dried out by the forge smoke drifting across from the armory. "You bought him out of the Oakhaven salt-pans, didn't you?"

Haddon adjusted his gloves, his mouth tightening into a thin line of civic authority. "He was acquired through legitimate requisitions from the southern satrapy. He is sixteen hands higher than the beasts we took from the western clans last winter."

"He’s high because he’s starved of lime, and his near shoulder was cracked when he was five years old," Bram said. He ran his hand—broad-palmed, scarred by dozens of glancing slips with the crescent knife—down through the matted wool to the hot hide beneath. The mammoth, an old tusk-shorn bull known in the stockade registers as Iron-Eye, let out a low rumble that vibrated through Bram’s shinbones and made the gantry pins hum in their mortises. "You put eight hundredweight of plate and twelve spearmen on this spine, Haddon, and the third time he takes a ditch, the saddle will snap his transverse processes like dry pine kindling. Then you’ll have sixteen tons of meat lying in the dirt, blocking the supply train, and the Sorcerer-King’s horse-archers will turn your spearmen into pincushions before you can cut the girths."

A third man stepped out from the shadow of the brick tanyard wall, his movements so smooth they seemed devoid of weight. He wore the gray homespun of a clerk, but his sleeves were lined with silver wire that caught the pale northern light, and the staff in his right hand was made of boiled ash tipped with a lump of greasy, green-veined river-slate.

"The Master Saddler is thorough," the gray man said. His voice was light, lacking the vulgar breathiness of the yard-workers, but it carried through the cold air with the unnatural clarity of glass struck by a needle. "That is why Lord Vael paid three silver talents to clear his debts with the Tanner's Bench."

Bram didn't pause his measurement. He slid the brass slide along the rod, noting the breadth across the ribs: six spans and three fingers. Wide enough for a double cinch, but the loin was short. "Lord Vael bought my workshop because his own artificers kept using unboiled walrus hide for the under-straps," Bram said to the slate-capped staff, not bothering to address the wizard's face. "Walrus stretches when it gets wet, and it gets very wet when a beast sweats under bronze barding. Two of his towers slid sideways at the Crossing of the Red Mere because some academy-trained idiot thought hide was just leather that hadn't been dyed yet."

The wizard, who called himself Brother Kaelen though no temple claimed him, smiled without showing teeth. "A practical failure. Easily rectified by practical men. Can you strap this bull or can you not, Master Bram? The army marches in forty days, with or without your approval, but Lord Vael would prefer his catapults to remain upright while they reduce the Redoubt of the Seven Nails."

"Everything can be strapped," Bram said. He marked the rod with a piece of charred bone, swung his leg over the platform railing, and slid down the grease-slicked post to the stones. He landed with a heavy, flat-footed thud that set his knees aching. He had been twenty years in the trade, and the damp cold of the northern marches had long since found its way into his marrow. "The question is whether you want him strapped for parade or strapped for iron."

"Explain the difference to the Master of Accounts," Haddon snapped. "The timber for the side-boards is already cut. Seasoned ash, three inches thick, sourced from the King’s preserve."

"Ash is too stiff for an animal that breathes six gallons of air a minute," Bram said, walking around the mammoth’s rear flank. He stayed four feet clear of the hocks; Iron-Eye had a habit of shifting his hindquarters to pin careless men against the stone revetments, an old trick common to draft-beasts that had spent their youth hauling cedar trunks out of the river-drifts. "A war-mount isn't an ox-cart with legs. When a bull charges, his pelvis drops three inches and his rib cage expands by nearly a palm's width. If your tree doesn't flex, the leather has to. If the leather stretches, the tower shifts. If the leather doesn't stretch and the wood doesn't yield, the girth breaks the ribs. You want three-ply laminate: birch on the outside for the grease-resistance, split willow in the belly for the give, and an under-plate of five-gauge ox-hide that's been curried with tallow and neat’s-foot oil until you can knot it around your wrist."

He stopped at the bull’s left rump, where an old brand had scarred over into a gray, hairless knot the size of an iron skillet. Bram laid the flat of his palm against it. The skin was hot—hotter than a draft horse, hot enough that he could feel the pulse of the great vessels beneath the fat.

"Look here," Bram said, tapping the edge of the scar.

Haddon leaned in, squinting, while Kaelen remained three paces back, his chin resting on his thumb over the slate head of his staff.

"A brand from the Southern Scriptorium," Haddon observed. "The three curls of the River-Gate. It shows he was part of the siege corps at Oakhaven."

"It shows he was burnt by sorcery," Bram corrected. He took an awl from the leather frog at his belt and gently prodded the skin half an inch above the brand. The mammoth did not kick, but its tail whipped against its thigh with a dry, leathery thwack, and a wet shiver ran through the massive flank. "Feel that? The muscle beneath is dead. It turned to gristle when the pyromancers threw pitch into the lines. You can't put a flank-stay there. The pad will rub the scar until it weeps, the flies will get into it within three marches, and by the time you reach the Seven Nails, the beast will be kicking at its own belly to stop the rot. You’ll have to cut him loose or kill him."

Kaelen stepped forward, his slate-headed staff tilting slightly. The green veins in the stone seemed to darken, like moss soaking up dirty water. "The wound can be numbed. A simple warding on the saddle skirt would prevent him from feeling the chafe."

Bram looked at the wizard then, meeting eyes that were small, pale, and entirely devoid of the grease that defined everyone else in the Caldera tanyards. "A beast that can’t feel its flank can’t balance its load, Brother. You numb that hip, and he’ll tread short on the left side. The saddle will list three degrees to the south, your tower-archers will lose their sight-lines, and after five leagues of gravel road, his off-forefoot will split from the uneven weight. You can't ward your way out of geometry, wizard. The leather doesn't care about your runes. It only cares about weight, grease, and the dirt between them."

Haddon looked between them, his fingers twitching toward the ledger book tucked into his tunic. "The contract stipulates four gross of iron-reinforced cinches by the end of the month, Bram. The King’s heralds are already at the outer gate. If we tell them we need six weeks to laminate willow for two hundred mounts—"

"I didn't say two hundred mounts," Bram said. He wiped his fingers on his leather apron, which was blackened down the front from thirty years of wax, fish glue, and animal grease. "I said this one. The rest of the southern draft are bullocks, mostly whole, with clean shoulders. They can take the standard iron-framed pack-trees if you drop the tower weight by ten stone. But Iron-Eye here is the bull Lord Vael intends for his personal siege-howdah, isn't he?"

Kaelen didn't deny it. "The Lord Vael requires an elevated platform for the brass mirror. He cannot cast across the river without twelve feet of clearance above the dust of the line. The mount must be the largest in the stable."

"Then the mount needs a split-tree saddle with a floating pommel," Bram said. "And you need to give me seven tanned bull-hides from the high valley—the ones that died in the snow, not the ones that were slaughtered in the vats. The grain is tighter on the winter kills. If I don't have them by tomorrow noon, you can build the saddle out of iron and watch it break the bull's heart before he reaches the salt flats."

He turned away without waiting for their consent and headed toward the main workshop. The snow had begun to fall again, thick, gray flakes that melted the moment they touched the manure-warmed slush of the yard.

The saddlery smelled of the only three things Bram trusted: birch-tar, boiled hoof-glue, and the bitter, oily tang of old leather shavings. It was a cavernous shed built against the southern wall of the grand armory, its rafters hung with hundreds of wooden templates that rattled like dry bones whenever the wind came over the palisade. Along the eastern bench, four journeymen were paring down harness straps with draw-knives, the ribbons of yellow-white hide curling over their boots like dried noodles.

At the center of the shop sat the Great Frame: an enormous trestle made of four-inch white oak, built to mirror the torso of an adult bull mammoth. It was scarred by thousands of awl-holes, notched by saw-teeth, and greasy from the lard used to slide test-harnesses onto its ribs.

A young man, barely nineteen, with ears that were permanently red from frost and sleeves rolled up to reveal forearm muscles like corded hemp, looked up from a tub of lard. This was Elid, Bram’s senior apprentice, who had spent the last three days soaking a three-inch-thick trace strap in cod oil to make it supple enough for the breast-collars.

"He wouldn't take the measure, would he?" Elid asked, leaning his weight against the scraper.

"He took it, but he didn't like the tally," Bram said. He unhooked his tool-belt and dropped it onto the low bench by the door. The iron tools clinked together—the round-knife, the edge-beveler, the pricking-irons, and the heavy brass-headed mallet he used for setting copper rivets through four layers of saddle-skirt. "Haddon has sold the Lord Vael on the idea that an engine-mount is just a bigger horse. He’s going to build the towers out of green oak to save on the transport wagon costs."

"The towers will warp," Elid said, not looking up from his work. "First hot day after the rain, the timbers will shrink, pull the corner-bolts through the wood, and pitch the sling-men into the mud."

"They will," Bram said. "And when they do, Haddon will tell the Scribe that the leather stretched, because leather cannot speak for itself to a tribunal."

Bram walked to the back of the shop, where the hides were stacked on raised cedar pallets to keep them out of the floor-damp. He pulled his round-knife from its sheath at his side—the blade was five inches of polished steel, curved like a crescent moon, ground down so many times by his grandfather, his father, and himself that the mark of the Solingen guild was half-swallowed by the bolster. He laid his palm against the topmost hide: a massive, dark steer-leather, five iron-weights thick, with a grain as smooth and dense as polished slate.

"This one was salted in the cold," Bram murmured, his fingers reading the hide the way a scholar reads a balance sheet. "The salt-man didn't burn it with lime. Good. The grain is solid."

"That’s the bull from the monastery herd," Elid said. "The one Brother Mark brought down before the frost set in. It’s four talents of silver for the piece, Bram. If we cut it for the floating tree and the wizard cancels the order—"

"The wizard won't cancel," Bram said. He reached for his chalk and began to strike the first line down the spine of the hide, four inches clear of the belly-drop where the skin was thin and spongy. "The wizard has seen the Pale Trench. He knows what happens to an army whose beasts fail them on the road. The Sorcerer-Kings don't fight with iron anymore, Elid. They fight with distance. They sit behind thirty feet of ditch and stone, and they wait for your mounts to founder in the marsh-silt. If our harness doesn't hold the weight of the casting-platforms, the wizard-kings won't even need to loose their lightning. The mud will do their work for them."

He drove the crescent knife into the leather. The cut went through with a sound like tearing linen—firm, crisp, with no drag in the core. That was the sound of proper cure: the oak bark had bitten all the way to the heart of the skin, leaving no raw jelly to rot when the rain hit it.

Outside, a sudden commotion rattled the yard. The high, trumpeting scream of an unsettled mammoth cut through the sound of the smithy hammers, followed by the splintering crack of timber and the frantic yelling of drovers.

Bram didn't stop the knife. He finished the curve of the cantle-flap, forty inches long, perfectly symmetrical to within the width of a needle-thread, before he laid the tool down on the clean cork board.

"That'll be the second bull," Bram said, wiping his thumb across the cut edge to check the grain. "The one with the split ear from the western pens. They tried to back him into the shoeing-chute without blindering him first."

Elid dropped his scraper and moved toward the half-open door of the shop, peering out into the swirling snow. "It’s Haddon. He’s tried to use an iron-jawed twitch on the tusk-root to keep him still for the plate-measurers."

"Of course he did," Bram said, picking up his mallet and a handful of three-inch copper rivets. "A clerk always thinks that if an iron bar hurts a dog, an iron bar will frighten a mountain. Get the heavy twitch-strap, Elid. The one with the double-sewn fleece lining. And fetch the lard-pail. We’re going to have to sew that beast’s lip before Haddon gets himself trampled into grease, or we’ll be building saddles for ghosts."

He walked out into the cold yard, his boots crunching in the red-stained slush where the tanners had emptied the refuse from the bark-vats. The wind was rising from the north, carrying with it the smell of high snow and the faint, ozone-sharp stink that meant the Sorcerer-Kings’ pickets were burning the heather five leagues out.

It was twenty miles to the river, forty miles to the trench, and there were two hundred mounts between the Scribe’s ambitions and the grave. Every single one of them had to be held together with six strands of linen thread and the skin of something that had died before it could be asked if it wanted to go to war. Bram spat into the snow, hefted the heavy leather strap over his shoulder, and walked toward the screaming beast.

The split-eared bull had backed himself into the angle where the stockade wall met the grain-store, and he was currently disassembling the siding with his left shoulder. Every impact produced a dry, echoing boom that sent flocking jackdaws out of the rafters in frantic, black clouds.

Master Haddon was on his knees twenty feet away, his fur-trimmed cloak half-buried in cold slush, clutching a wrist that hung at an angle not intended by nature. Two drovers were trying to haul him backward by the collar while avoiding the spray of gravel and shattered pine laths thrown up by the mammoth’s hind feet.

"Get the chain around his off-knee!" Haddon was wheezing, his face the color of skimmed milk. "He cost seventy imperial crowns! Bram, strike his ear-cord!"

"If anyone strikes his ear, he’ll take down the corner-post of the granary, and we’ll all spend the winter eating frozen rye off the cobbles," Bram said without raising his voice. He walked steadily past the groaning clerk, the heavy, fleece-lined twitch-strap swinging from his left hand. "Elid, take the bucket. Stay by the water-butt and don't make a sound. When he swings his trunk, don't jump. He expects you to jump. When you jump, he knows he’s bigger than you are, which is an idea no draft-beast should ever be allowed to entertain."

The bull was younger than Iron-Eye, leaner in the flanks, and coated in coarse, cinnamon-colored winter wool that smelled strongly of sour mash and fear. A frayed hemp halter had bitten deep into the flesh above his nostrils, where dried blood had caked into black scabs. Someone had tried to curb him with an iron ring through the septum—a mule-driver’s trick that worked splendidly on an ox until the ox realized it possessed the bone density of a battering ram. The ring had torn out through the cartilage, leaving a ragged flap that whistled every time the beast drew breath.

Bram stopped four paces outside the bull's reach. He didn't look at the small, bloodshot eyes; instead, he watched the ears. They were flared wide, pinned back against the thick wool of the neck, their tips shivering with tension.

"You're a miserable lump of tallow, aren't you?" Bram said, his voice dropping into the low, monotonic grumble he used when leveling the workbench. He dipped his fingers into the small clay jar of boiled fat he carried in his apron pouch and smeared it across the knuckles of both hands. "Brought down from the scrub-hills, starved on moldy hay, and then expected to haul forty hundredweight of green pine for a pack of quill-pushers who don't know the difference between a cinch and a garrote."

The bull gave a wet, shuddering snort, showering Bram’s chest with gray mucous and flecks of frothy blood. Bram didn't flinch. He took half a pace forward, planting his left boot deep into the slush to find the solid stones beneath. With his right hand, he extended the wide leather strap, offering the greased fleece surface to the animal's searching trunk.

The trunk tip—a pair of sensitive, prehensile lips covered in coarse sensory bristles—quivered, reached out, and touched the tallow. To a wild bull, the smell of animal grease was foreign, but to a working draft-mount, it meant the end of the day's march: the removal of the yoke, the warm mash, and the straw bed. The massive head lowered an inch.

"That’s it," Bram murmured. "Salt and lard. Better than iron, isn't it?"

With a smooth, practiced twist of his forearms, Bram looped the wide fleece band over the tender base of the trunk, just below the ruined septum, and took two wraps around the ash-wood toggle he held in his palm. The bull started to rear back, muscles bunching across his broad, sloping shoulders, but Bram did not pull against the pull. Instead, he leaned his entire weight into the toggle, twisting it half a turn so the soft fleece pressed firmly against the sensitive nerve cluster behind the upper lip.

It was not a blow; it was a clamp. The pressure sent an immediate, overwhelming signal to the mammoth's hindbrain to stand still and lower its head. The bull’s knees buckled slightly, its ears dropped from their combat flare, and a long, low whine whistled through its nostrils.

"Elid," Bram said calmly. "The needle."

Elid stepped up on the blind side, moving with the quiet deliberation of a youth who had spent five years around five-ton animals that could end a life with a careless shift of the hips. From his pouch, he drew a curved harness needle four inches long, threaded with thick, triple-waxed flax cord, along with a pair of flat brass pliers.

"Hold the flap," Bram ordered.

Elid took the torn cartilage between two calloused fingers, wiping away the dirt with the corner of his rough woolen sleeve. Bram kept the toggle tight with his left wrist, using his free hand to steady the trembling, velvet skin of the upper lip. With three swift, heavy thrusts of the brass pliers, Bram drove the needle through the torn gristle, pulling the edges of the wound together in a neat, overlapping whip-stitch.

The bull flinched with each pass, its tail lashing its flanks, but the pressure on the twitch held it grounded. Bram knotted the waxed thread with a hard, square hitch, severed the ends with his teeth, and smeared a thick gob of pine-pitch over the wound to keep out the blowflies that nested in the warm armory dung-heaps.

"Cut the hemp halter," Bram said, releasing the toggle.

Elid drew his knife and slashed through the frayed rope behind the ears. The heavy hemp fell away, thudding into the muck. Relieved of the biting fibers and the torn ring, the young bull gave a long, shuddering sigh that blew the loose shavings out of Bram's beard. It didn't bolt. It simply stood there in the snow, its trunk hanging limp, licking cautiously at the taste of salt and grease on its upper lip.

"Now get him into the third pen," Bram told the drovers, who were still lingering by the granary corner with their useless iron hooks. "Give him two baskets of steamed oats and double the salt-lick. If I catch any of you using a pig-iron twitch on his tusk again, I’ll stitch your thumbs to your belt-loops. Clear out."

The men scrambled to obey, leading the placid beast away by the neck-rope while Bram walked back toward Haddon, who was being helped to his feet by Brother Kaelen. The wizard looked pristine; not a flake of gray snow had stuck to his homespun robes, and his slate staff remained dry despite the squall.

"He broken?" Bram asked, looking at Haddon's dangling hand.

"The radius is cracked," Kaelen said, his voice as cool and detached as a clerk tallying beans. "The joint is displaced. He will not hold a quill for six weeks."

"Then he won't be writing requisitions for cheap green ash," Bram said. He bent down, scooped up his dropped mallet from the mud, and wiped the face on his trousers. "Which saves us three days of arguing. Brother Kaelen, if you want sixty war-mounts ready to march with your grand batteries by the end of next month, you need to sign over the dry-sheds to the Saddlers' Guild today. Not tomorrow. Today."

Haddon hissed through his teeth as a drover bound his wrist with a strip of dirty linen. "The dry-sheds belong to the Master of Artillery, Bram! That timber is reserved for the siege-frames and the trestles!"

"Your siege-frames won't do much shooting if they’re lying in a ditch three miles outside the gates because the draft-cinches snapped," Bram countered. "I need forty planks of three-season ash for the saddle-bars, and I need the entire stock of winter-slaughter hides from the high valley stores. Every square inch of it."

Kaelen tapped his slate-tipped staff once against the frozen ground. The hollow thunk cut through the yard noise like an iron bell. "You shall have the sheds, Master Saddler. And the ash. But you will also take five apprentices from the College of Artificers. Lord Vael insists that our own initiates learn the construction of the sovereign frames."

Bram’s jaw tightened. "Artificers don't know leather. They think hide is just thin wood that bends. They’ll dull my knives, split the welts, and drop their wax into the glue-pots."

"They will obey your instructions," Kaelen replied, his pale eyes fixing on Bram with an intensity that felt like a draft coming under a door. "Or you may hang them from the rafters by their own stirrup-leathers. Lord Vael does not care about their comfort. He cares about the third line of the Pale Trench. If the mounts fail, the mirror-batteries fall into the hands of the Sorcerer-Kings, and the Caldera will be plowed with salt. Does the leather understand that, Bram?"

"The leather understands what it’s told," Bram said. "Provided the man with the awl knows his business. Send them to the shop at third bell tomorrow. If they’re wearing silk sleeves, tell them to leave them behind. Birch-tar doesn't wash out."

He turned on his heel and strode back toward the warm, pungent refuge of the saddlery, leaving the wizard and the injured clerk standing in the red-stained slush.

Inside the workshop, the fire in the center hearth had caught properly, sending a thick column of sweet-smelling peat smoke up through the vent in the high roof. The heat had loosened the smell of the room: the sharpness of vinegar used to strip grease from hides, the heavy, comforting stench of rendering fat, and the resinous bite of pine pitch.

Elid was already at the great bench, using a broad wooden spatula to spread warm neatsfoot oil over a side of eight-gauge skirting leather. His sleeves were rolled past his elbows, his forearms glistening with the golden grease.

"Did the wizard threaten to turn your blood to tallow?" Elid asked without looking up.

"Worse," Bram said, hanging his tool-belt on its iron peg. "He’s sending us five boys from the Academy."

Elid paused, his spatula hovering an inch above the hide. "Scholars? In the tanyard?"

"Scholars," Bram grunted. "Boys who can calculate the trajectory of an incendiary bolt to within three barleycorns, but who have never held a stitching horse between their knees. We’ll have them skiving harness-straps until their knuckles bleed. If they survive that, we’ll teach them how to split a hide without ruining the grain."

Bram walked over to the Great Frame, the massive oak mock-up that dominated the center of the floor. He ran a rough palm along the curved wooden ribs. The frame had been built thirty years ago by his master, old Girth-Smith Vorn, to match the proportions of the legendary bull that carried the Iron Duke across the frozen lakes. It was scarred, dark, and greasy from three decades of fitting, but it remained the true standard of the Caldera.

"We start on Iron-Eye's tree tonight," Bram said. "Fetch the ash blanks from the small loft. The ones we set aside two winters ago. The straight-grained ones with no knot-eyes."

Elid nodded, wiped his hands on a rag, and climbed the ladder into the dark rafters. A moment later, the heavy thuds of seasoned wood hitting the floorboards echoed through the shop.

Bram pulled down his master-gauge—a large, hinged quadrant of dark brass inscribed with arcs and notches. He set the brass foot against the spine of the frame, sighting down the curve.

A saddle for a war-mammoth was not an enlarged horse saddle; the mechanics were fundamentally different. A horse carried its weight upon its spine and ribs, but a mammoth’s vertebrae were topped by massive, vertical bone spurs that supported the immense neck muscles needed to swing six-foot tusks. If a saddler placed weight directly upon those dorsal spines, the animal would be crippled within two leagues.

The weight of the war-howdah—a structure carrying twelve hundredweight of timber, bronze armor, two crewmen, and a sorcerer’s focusing mirror—had to rest entirely on the broad muscular shelves that ran parallel to the spine, suspended above the bone by an arched bridge of laminated wood.

The bridge, or the "tree," had to be rigid enough not to flatten under the recoil of a platform-mounted ballista, yet flexible enough to breathe with the beast’s lung-stroke. It was an impossible balance of forces, one that cost empires fortunes in dead mounts every campaigning season.

Elid dropped from the ladder, carrying two six-foot beams of dry, white ash under each arm. He laid them across the saw-horses. The timber was bone-dry, pale as bleached bone, and rang with a clear, bell-like tone when tapped with a knuckle.

"Grain runs straight down the length," Elid reported. "No twist. Dried in the shade, away from the smoke."

"Good," Bram said. He took up his broad adze, spitting on the whetstone before giving the curved edge a final polish. "We split them into quarter-inch laths. Seven for the near-bar, seven for the off-bar. We laminate them with fish-glue and hide-size, pinned every six inches with seasoned horn-dowels."

"Horn?" Elid looked up, surprised. "Not copper rivets?"

"Copper shears when it gets cold," Bram said, straddling the first ash beam. He sighted down the edge, his muscles tensing as he prepared to strike. "You get out onto the Pale Trench at midwinter, the temperature drops until spit freezes before it hits the ground, and copper turns brittle as sugar candy. One good heave from the bull when he’s climbing a frozen ditch, and the rivets snap like dried peas. Horn moves with the wood. It shrinks when the ash shrinks, swells when the ash gets damp, and never rusts."

He brought the adze down. With a clean, ringing chock, a translucent curling ribbon of white wood peeled away from the timber, releasing the crisp, clean scent of dry ash into the smoky shop.

For three hours, the two men worked in rhythmic silence, broken only by the steady rasp of the draw-knife and the wet thud of the adze. Outside, the wind howled around the corners of the armory, rattling the iron chimney-caps and driving dry, gritty snow through the chinks in the timber walls.

By midnight, fourteen curved laths lay stacked upon the central bench, each planed to an exact, tapering thickness that grew thinner toward the ends to allow for the animal’s shoulder roll.

Bram stood over the glue-pot, which sat in a basin of boiling water over the coals. The hide-glue—made from boiled ox-hooves and scrapings from the lime-vats—was thick, amber-colored, and smelled like an old kennel. He lifted the wooden paddle, watching the stringy resin run back into the pot in a smooth, continuous ribbon.

"Temperature is right," Bram said. "Get the clamps. Once the glue touches the wood, we have forty heartbeats before it skins over in this cold."

Working in tight coordination, their breath misting together in the drafty air, Bram and Elid slathered the warm, sticky amber along the face of each ash lath. They stacked them together, bending the flexible bundle over the curved oak ribs of the Great Frame.

Elid threw his weight against the iron screw-clamps, his jaw clenched, veins standing out like blue cord along his neck as he cranked the handles down. Bram followed behind him, tapping the edges with his brass mallet to ensure the laths remained aligned to within the thickness of a fingernail, driving the horn dowels home with short, sharp strokes that set the wooden pins flush with the outer grain.

The glue squeezed out from the seams in thick, golden beads, sizzling as it dripped onto the warm stones of the hearth.

When the final clamp was tightened, Bram stepped back, wiping his sweaty brow with the back of a hand blackened by charcoal and grease. The arched saddle-tree stood clamped to the frame, a curving arc of tensioned timber that possessed the strength of an iron girder and the spring of a bow.

"That'll hold," Elid panted, leaning his forearms on the bench to catch his breath. "That’ll hold whatever mirror the wizard wants to mount on it."

"It’ll hold the mirror," Bram said, peering closely at the seam where the dowels met the wood. "The question is whether the belly-cinch will hold the tree. You can build a bridge out of ash and horn, but if the strap that keeps it on the beast is weak, you've just built a very expensive sled for your wizard to ride into the mud."

He walked over to the pile of winter-kill steer hides he had selected earlier. He hauled the top hide onto the cutting table, smoothing it out with his scarred palms.

The leather was thick—nearly three-eighths of an inch at the butt—dense, and firm. But for a war-cinch that had to withstand the explosive expansion of a mammoth’s chest when it trumpeted a charge, simple steer-leather was not enough.

"We make a three-fold strap," Bram told the apprentice, tracing a line on the hide with a piece of sharpened soapstone. "A core of raw, unboiled ox-hide for tensile strength, encased in oil-tanned steer to keep out the wet, backed with boiled sheep’s wool to prevent galls. And every stitch has to be double-backstitched with four-strand waxed linen. No shortcuts."

"That’s sixteen yards of hand-stitching," Elid remarked, eyeing the heavy spools of thread hanging from the beam. "My fingers won't straighten out until the spring thaw."

"Your fingers will straighten out when the war is won," Bram said dryly. "Or they won't, and you can buy yourself a wooden hook and work as a gatekeeper. Hand me the strap-cutter."

The tool was an ancient piece of brass and polished cherry-wood, slotted with a razor-sharp steel blade that could be adjusted with a thumbscrew. Bram set the width to four inches—the standard broad-girth measure—and pressed the guide against the straightened edge of the hide.

With a single, steady pull that engaged his entire torso, Bram drew the cutter down the length of the hide. The blade sliced through the dense leather with a low, satisfying hum, producing a strap eight feet long, perfectly uniform, with edges as sharp and clean as planed timber.

He cut four identical straps before laying the tool down. He picked up one of the strips, twisting it between his hands to test the temper. It offered formidable resistance, bending with a slow, heavy yield that showed the oak-bark tanning had reached the absolute center of the corium.

"Now," Bram said, "we bevel."

He took up the edge-beveler, a tiny, two-pronged chisel with a scooped center, and began running it along the sharp corners of the leather strap. Tiny, curled shavings of black leather fell to the floor like wood-shavings. An un-beveled strap would bite into the animal's flesh once the leather grew stiff with dried sweat and road-grit; a beveled strap, rounded on both margins, would slide over the hair without cutting.

It was slow, tedious, unglamorous work. It was the work that had won the Siege of the White Sluice twenty years ago, and the work that had failed the Emperor at the Battle of the Red Mire, where half the baggage train had foundered because some contractor in the capital had used square-edged straps that sawed through the skin of the draft-bulls' armpits until the beasts refused to lean into their collars.

The door to the saddlery creaked open, admitting a blast of freezing air and a swirl of fine, dry snow.

Bram didn't look up from his beveling. "Shut the door. You’re letting the damp into the glue."

The door thudded shut, but the footsteps that followed were too light for a tanner and too hesitant for a soldier. Bram glanced up through his shaggy, graying eyebrows.

Standing just inside the threshold was one of the wizard's initiates. He was barely more than a boy, perhaps seventeen, wearing the gray woolen mantle of the Artificers over a blue tunic that was far too clean for the Caldera. His hands were tucked deep into his sleeves, his shoulders hunched against the lingering cold of the yard. Across his chest hung an ink-stained leather satchel containing scribing tools, and around his neck was a bronze medallion stamped with the geometric sigil of the College of the High Trench.

"Brother Kaelen said... he said I was to report at once," the youth stammered. His teeth were chattering slightly, and his eyes darted nervously between the looming skeleton of the Great Frame and the blood-stained apron Bram wore. "I am Artificer-Novice Corin."

Bram stopped the beveler. He looked at the boy’s boots: fine, thin calfskin with fashionable split-toes, completely ungreased, already soaked through and stained with black snow-slush.

"Did Brother Kaelen tell you what we do here, Novice Corin?" Bram asked softly.

"I... I am instructed to study the mechanical suspension of the primary mounts," the boy said, straightening his shoulders in a pathetic attempt at academic dignity. "To record the dimensions, verify the tensile thresholds of the load-bearing stays, and ensure the runes of stabilization are properly inscribed upon the foundation plates."

Elid let out a short, snorting laugh from behind the glue-pot. Bram held up a finger, silencing the apprentice.

"Tensile thresholds," Bram repeated slowly, tasting the words as if they were bad beer. "Runes of stabilization."

He reached down, picked up a heavy, curved crescent knife from the bench, and tossed it through the air. The five-inch blade spun twice, striking the heavy pine chopping-block six inches from Corin's right boot with a solid, vibrating thwack.

The boy jumped half a foot, clutching his satchel to his ribs.

"Take off the fine coat, Corin," Bram said, turning back to his strap and resuming his beveling. "And pick up that knife."

"I... I am a scholar of the third circle," Corin protested, his voice rising an octave. "My contract with the Lord Vael specifies—"

"Your contract specifies that if my saddles fail, your Lord Vael gets his throat cut by the horse-archers of the Sorcerer-Kings," Bram said, his tone entirely devoid of anger, flat as an iron anvil. "And if my saddles fail because an Artificer didn't know how to skive a lap-joint, I’ll personally throw that Artificer into the lime-vats to see if his bones make better glue than an ox."

He pointed with his chin toward a wooden tub in the corner, where three unworked cow-hides lay soaking in a brine of water, wood-ash, and fermented barley.

"Take the crescent knife, pull those hides out of the tub, and scrape the hair off the grain," Bram commanded. "You use the dull edge, held at sixty degrees, and you push with your belly, not your wrists. If you cut the skin, you’ll sew the patch with your own thread. If you finish before the morning bell, I’ll show you how we balance a tree so it doesn't snap a mammoth's backbone when your master starts throwing his lightning."

Corin stared at the tub, which smelled like three weeks of dead dog and wet wool. His face turned an interesting shade of olive green.

"Go on," Bram said quietly. "The war doesn't wait for your ink to dry, scholar."

The boy stood frozen for three heartbeats. Then, with trembling hands, he unbuckled his satchel, set it carefully on a dry corner of the bench, and unpinned his fine gray mantle. He stepped across the shavings, his thin boots squelching in the grease-filmed sawdust, and reached for the haft of the crescent knife buried in the chopping block.

Bram watched him out of the corner of his eye as the boy pulled the steel free with a grunt of effort. The lad's grip was terrible—all fingers, no palm—and he held the crescent like a butcher about to hack at a pig, but he didn't run back into the snow.

"Keep your thumb on the spine of the blade, boy," Bram muttered, not looking up from his own work as the beveler zipped through the last foot of the girth-strap. "Or you'll leave half your meat on the cutting board before the third bell rings."

The apprentice nodded dumbly, rolled his sleeves past his thin, pale forearms, and hauled the first dripping, foul-smelling hide onto the scraping beam.

Bram laid the finished strap aside and picked up the second one. The wind outside rose to a shrill whistle, rattling the heavy shutters of the saddlery, but inside, the ash wood was holding fast in the clamps, the glue was setting in the heart of the laths, and the leather was being shaped to bear the weight of kings. It was going to be a long, cold night, and there were still a hundred and ninety-nine beasts waiting for their measure.
