The Pacific sun hung like a molten coin in the sky, hammering the camp into submission. That crude stone mortar? Pure torture now. Isaac's whimper cut through the air as he dropped another handful of wild oats into the depression. His hands—raw and weeping where blisters had burst—trembled like storm-shaken leaves when he lifted the pestle. Thump. Thump. Thump. Each dull impact echoed the futility, yielding barely a teaspoon of coarse, greyish flour. Sweat stung his eyes, salty and sharp, mingling with tears that tasted of copper and defeat.
"Still won't feed a sparrow," Smith muttered, peering into their fraying grass storage basket. His spectacles slid down his nose, smudged with fingerprints, as he scratched numbers into a water-stained logbook. The graphite left charcoal streaks on his knuckles. "Six hours a day. For five mouths. Madness."
Thomas wiped grease-blackened hands on trousers already stiff with grime. His restless energy pulsed like banked coals as he eyed the scavenged iron scraps. "There's got to be a better way than this bone-breaking—"
"Wind." Leo's voice sliced through the complaint, clean as a knife. He stood silhouetted against the shimmering sea, hair dancing in the breeze. "We harness the wind."
Hardin paused, the rhythmic scrape-scrape of his spear-sharpening stone halting. His broken arm hung stiff in its sling. "Explain."
Leo snatched a charred stick. In the damp sand, lines took shape: a vertical shaft crowned with angled sails, crossbeams spiderwebbing down to a horizontal grinding stone. "Wind catches these," he traced arcs in the air, "spins the shaft. The shaft turns this gear—"
"Gear?" Thomas crouched, brow furrowed. "Like... a wheel with teeth?"
"Precisely. Transfers rotation to the millstone." Leo's finger jabbed the connection point. "Top stone spins. Grain feeds through. Flour pours out."
Isaac's eyes widened, flour-dust clinging to his lashes. "A water mill... but with air?"
Smith adjusted his spectacles, the lenses catching the harsh light. "Theoretical soundness, Mr. Chen. Practicality? Bearings. Gear ratios. Structural integrity—"
"We've got tools!" Thomas cut in, gesturing to the salvaged crowbars, files, and rust-pitted hammers scattered near the pirate cache. "And that hardwood grove north of the spring. Tough as old nails."
Night draped the camp like a damp cloak. As snores rumbled, Leo's mind ignited.

[WARNING: Insufficient Historical Context. Employing Simplified Models]
Schematics exploded behind his eyelids—windmill shafts fracturing into cross-sections, bearing housings glowing like ghostly ribs, primitive stone drives rotating in wireframe. Equations scrolled: tangential wind force coefficients, minimum torque thresholds for grain crushing. Knowledge flooded him, translating cold engineering into muscle-memory.
Axle... must be true. Bearings... here... friction points. Leather belts... cross-laced... grip like teeth.
Dawn found him blinking, blueprints seared onto his retinas, the scent of salt and dew sharp in his nostrils.
"Right," Leo announced, charcoal biting into a smoothed slab of driftwood. Lines took shape: shaft, sails, gears. "Thomas—main shaft. Eight feet. Straight as God's arrow. Hardin—densest timber for the frame. Smith—wind angles. Strongest gusts. Isaac—every scrap of leather. Straps. Belts. Anything."
Thomas ran calloused fingers over Leo's sketch of an iron bearing sleeve. "This collar... needs to hug the axle tighter than a jealous lover but spin smoother than a greased pig. Near impossible with these." He held up a rust-scabbed file.
Leo thrust a fist-sized lump of crude pig iron into his hands. "Then file. Hollow cylinder. Inside diameter exactly the shaft's thickness. Outside thick enough to hold grease."
"Grease?"
"Boar fat. Smith found a nest."
Thomas stared at the file, then the iron. A slow, feral grin split his face. "Now that's a proper challenge."
The camp thrummed like a kicked beehive.
Hardin, his broken arm a constant ache, directed the felling of two ironwood giants. The crack of splitting timber echoed off the cliffs. Ropes groaned as they hauled the trunks back, the scent of sap sharp as turpentine. Thomas attacked the wood, adze and drawknife flashing. Days bled into blisters, then blood, then leather strips wrapped around his palms as makeshift gloves. Shavings piled like snowdrifts around the emerging shaft—tapered, massive, smelling of raw earth and effort.
Smith became a wind-whisperer. His driftwood quadrant, strung with knotted twine, measured the capricious gusts. "Peaks mid-afternoon!" he shouted over a gale that tasted of salt. "Optimal sail pitch—thirty degrees! Any steeper, it chokes! Shallower, it slips!"
Isaac scrambled along the beach, bare feet sinking into cool, wet sand. He tapped sandstone slabs with a hammerstone, listening for the dense thunk of good grain. Two passed: one broad and flat, the other thick as a warrior's shield. "Grinding stones!" he panted, dragging them back, the coarse rock scraping his forearms raw.
Leo's world dissolved into a fever of problems.
Problem One: The Bearings.
Thomas's filed iron sleeve fit snugly over the shaft's end. But friction screamed like a tortured cat. "Seizes!" Thomas growled, iron dust coating his sweat like metallic paint. "After half a turn!"
"Smith! The fat!" Leo ordered. They packed the cavity with waxy, rancid-smelling boar grease. "Rotate. Slowly." The shaft turned—a grinding, shuddering revolution. "Needs a reservoir," Leo realized, the grease already oozing out. "Thomas—can you file a groove inside? A channel to trap the slick?" Another day vanished under meticulous filing. The groove held. Friction halved. The shaft turned with a heavy, greased purr.
Problem Two: The Sails.
Hardin lashed broad palm fronds to spars. The wind caught them—and shredded the fronds like wet paper. "Brittle!" Smith yelled, shielding his eyes from flying debris.
"Smithsonian wisdom?" Hardin grunted, his sling damp with sweat.
"Survival instinct, Captain!" Smith shot back. "We need woven. Flexible. Strong."
They spent a day weaving a lattice of sinewy vines, fingers cramping. Lashed to the spars, the wind filled it like a sailcloth belly. The shaft groaned, turned—then juddered to a halt.
"Angle's wrong!" Leo shouted. The lattice fluttered like a trapped bird. Smith consulted his wind-stained notes. "Thirty degrees! Adjust the spars!" Thomas and Hardin hammered wedges beneath the bases. Wood creaked in protest. The lattice snapped taut. The shaft began a slow, majestic rotation, whispering against its greased bearings.
Problem Three: The Drive.
Connecting vertical shaft to horizontal stone demanded a right-angle drive. Precision gears? A pipe dream. Leo improvised. "Large wheel here," he sketched, charcoal snapping. "Small wheel here. Leather belt looped over both."
Thomas carved the wheels from heartwood, the dense grain resisting his knife. Isaac braided wet leather strips into a thick, pliable belt that smelled of tannin and brine. They mounted the small wheel to the millstone axle, the large wheel to the shaft. Leo looped the belt.
The shaft turned. The large wheel spun. The leather belt slithered... and slipped.
"Friction!" Leo groaned. Thomas grabbed the grease pot. "No!" Leo knocked his hand aside. "Grease makes it slide!" Isaac stared at the slithering belt, then at the nearby stream. "Wet it!" He sprinted, plunged the belt into the cool water, slapped it back onto the wheels.
The wet leather gripped with a hungry thwack. The large wheel spun the small. The millstone axle began a furious, wobbling dance.
Silence crashed down, thick as wool. The afternoon wind, steady and insistent, bellied the lattice sails. The shaft turned, smooth and heavy in its greased cradle. The large wheel spun, a blur of dark wood. The wet leather belt held, humming with tension. The smaller wheel whirred. And then—the heavy upper millstone began to rotate, a ponderous, grinding waltz atop its stationary partner.
Leo poured a handful of wild oats into the central hole.
Breath caught in five throats.
A soft, rhythmic whisper-crunch rose, like pebbles tumbling in a distant tide. From the gap between the stones, a trickle of fine, pale flour spilled, dusting the woven-grass mat below like the first snow of winter.
Then it became a stream. A cascade.
A ragged cheer tore through the air. Thomas threw back his head and roared—a sound of pure, primal triumph that shook the palm fronds. Hardin clapped his good hand on Smith's shoulder, a fierce, rare grin splitting his weathered face. Smith fumbled for his logbook, sketching frantically, ink blotting the page like spilled blood in his haste. Isaac danced in the flour-fall, laughing until he choked on the dusty cloud, his blistered hands held high like trophies.
Leo leaned against the solid timber frame, the vibration of turning wood and grinding stone thrumming up his spine, resonating in his bones. He watched the flour cascade—not just grain crushed, but time reclaimed, labor transformed. It smelled of dust and heat and impossible victory.
Smith stopped sketching. His gaze lifted to the sails, harnessing the invisible wind. "We are not merely surviving, gentlemen," he breathed, voice thick with awe. "We are commanding an element. We've made the wind our drudge."
Hardin nodded slowly, eyes narrowed. That turning force... "Apply it horizontally," he murmured, the soldier surfacing. "Attach blades... or spikes. Could scour a beach clean." The engine of bread held the seed of war.
As the sun bled into the horizon, painting the sky in molten copper and bruised purple, they ate. Simple oat gruel, boiled with scraps of leathery dried fish. But it was their flour. Ground by their mill. Powered by wind they had bent to their will. The gritty texture clung to their teeth, tasting of sweat, iron, and triumph.
Leo sat apart. The windmill's silhouette turned against the twilight—a dark, rhythmic cutout against the dying light, a primitive monument to stolen ingenuity. Its sails whispered promises on the salt-tinged air.
Inside his vision, pale blue text pulsed, cold and stark:

His gaze snapped to Isaac, happily scraping his bowl clean. The raw, weeping blisters on the boy's small hands stood out like beacons in the firelight. Medical Knowledge Base. The next battleground. The windmill stood tall, its sails catching the last sigh of the day's breeze—a promise etched in wood and stone. The first, fragile spark of controlled energy. The foundation stone of everything yet unbuilt. Leo closed his eyes. The deep vibration of the turning world hummed beneath his palms, a tangible pulse of the climb begun.
