The winding of the copper required a delicate, repetitive precision that the factory floor had never before demanded. Unlike the robust, heavy wool threads that broke with a snap and could be knotted together in a heartbeat by a careless apprentice, the thin copper wire was an unforgiving medium. If a boy pulled the tension lever too hard on the winding frame, the red metal would stretch, narrow, and develop a microscopic fracture that would instantly short-circuit the line once the current was introduced.
Thomas stood along the eastern wall of the Great Hall of Wheels, where Wat had constructed a specialized five-spindle winding bench. The machine was driven by a narrow, secondary leather belt that split off from the main axle, turning five small wooden bobbins at a fraction of the speed of the weaving frames. Above each bobbin sat a small tin funnel filled with boiled linseed oil and crushed pine resin, dripping a slow, amber-colored bead onto the wire just as the linen threads wrapped around the metal core.
He pulled the glass device from his tunic, using a dry corner of his smock to clear the fine spray of oil that hung in the air near the bench.

He opened his local storage cache and scrolled down to the basic electrical insulation protocols he had extracted before the system downgrade. The text was clear on the physical properties of organic dielectrics: three separate layers of fine-weave linen, fully saturated with oxidized linseed oil, provided enough dielectric strength to isolate up to five hundred volts of direct current, provided the wrapping remained completely free of moisture. The text emphasized that any gap in the linen layer would allow the current to bleed directly into the damp timber frames, grounding the entire circuit before it ever reached the refinery vats.
He checked the incoming message queue, the green characters appearing in a single, unadorned block against the dark background.
His mother wrote that she had spent the morning working in the kitchen, trying to scrape the old, yellowed linoleum tiles off the floor near the refrigerator where the water line had leaked during the summer. She found an old roll of black electrical tape that he had left in the utility drawer—the heavy, rubbery kind that smelled faintly of sulfur and adhesive grease. She mentioned using it to wrap the frayed cord of her old metal toaster before she plugged it back in, noting how remarkable it was that a simple strip of sticky fabric could keep the spark from biting her fingers. She closed by saying the kitchen looked very bare with the floorboards exposed, and she hoped he was making good progress with his foundation work.
Thomas rested his calloused thumb against the edge of the glass, his eyes tracking the word toaster. In Denver, his mother could manipulate domestic thermal energy with a five-inch plastic lever and a thin strand of nichrome wire, isolated by a standard rubber plug that cost less than a nickel at the corner store. Here, to achieve even the simplest form of electrical isolation for his copper lines, he was forcing twenty young girls to spend their days drawing raw flax through iron combs, spinning it into an ultra-fine yarn, and boiling it in volatile pine sap until their fingers were raw and stained a deep, permanent amber.
"The wire is holding its gauge, Thomas," Wat said, limping up from the lower gears with an empty oil can in his fist. He stopped by the winding bench, his single good eye watching the copper strand slide through the tin funnel with a mixture of pride and profound confusion. "The linen wraps tight enough, and that resin mix dries as hard as a horn spoon once the air hits it. But the girls are complaining about the fumes. They say the boiled sap makes their heads swim if they sit by the bobbins for more than two hours."
"Tell them to open the upper casements, Wat," Thomas said, locking the screen and tucking the device back against his ribs. "The resin needs the moving air to oxidize the oil anyway. If the sap stays wet inside the linen, the current will find the water and split the insulation from the inside out."
"The Baron's bailiff has crossed the boundary stones again," Victoria said, her voice dropping into a tight whisper as she stepped down from the counting room stairs. She held her small ink-horn in her hand, her thumb stained black from the daily scrip tallies. "He didn't bring the horsemen this time, Thomas. He came alone on a mule, and he has a large wooden box strapped to the saddle. He's sitting by the river-gate wall right now, waiting for Hamo to finish the midday level."
Thomas turned his head, his cloak sweeping the edge of the timber frame. "What's in the box?"
"The standard weights for the Oakhaven market," Victoria said, her face tightening into that hard, analytical expression that mirrored Thomas's own clinical focus. "He says the sheriff has issued a new decree regarding the measurement of the wool bales. He's demanding to check our iron balance-scales against the King's beam before the next wagons are loaded."
"He's looking for the margin," Thomas said, walking toward the wide oak door that opened onto the courtyard. "He knows our scrip is valued higher than his silver pence because our bales are uniform. If he can find an error in our balance—even a quarter-ounce on a sixty-pound roll—he can declare our whole ledger fraudulent under the royal weight-laws."
He walked out into the yard, where the drizzle had finally stopped, leaving the brickwork of the worker cottages looking sharp and clean against the grey limestone of the hill. The valley was silent except for the heavy, rhythmic thud-clack of the looms and the low, industrial hum of the winding bench behind him.
He reached into his tunic and verified the location of his phone, the subtle heat of the battery reassuring against his ribs. The future was still nothing but an unindexed ledger of bare text, but as the apprentices carried the first fully insulated spool of red wire toward the experimental vats by the mill-race, Thomas knew the boundary conditions were already set.
