Calibrating Companions and Conversation

Tamsin Vireo had learned to judge the city by the sound of its sky. On some mornings the brass flues above the arcades chimed like a distant tempering bell, a thin metallic hum that left a fine sheen of soot across the windows. Other days the sky roared with dirigible cables rubbing against each other, and the city smelled of hot iron and sugar from the market’s caramel stalls. She kept a small tray of burnt-cream biscuits by the workbench — the baker two doors down insisted they tasted best as if singed — and she would eat one between calibrations like a sacrament.

Her little shop crouched beneath a tangle of supply pipes and a platform where maintenance crews leaned like gnomes against the underbellies of lighter-than-air craft. Tamsin arranged tools the way some people arranged their books: brass spanners at right angles, a set of graduated calipers like a staircase, a row of tiny empathy-valves on a velvet scrap. Her calibrator — a hand-tool no larger than a loaf of bread and wired with brass filigree — simmered on the bench, its dial blinking a soft green.

A companion lay half-open beneath a lamp, the copper breastplate lifted like a lid. The little automaton had belonged to Old Caleb March; its name, attached to a painted strip on the chassis, read "Pip" in careful block letters. Pip’s hands, jointed and varnished, were folded as if in polite slumber. Tamsin's fingers hovered before she touched, as if the machines expected ritual. She slid a flat screwdriver under a rivet and eased the faceplate open.

Inside the chest, gears nested like a miniature city. Pneumatic bellows inhaled and exhaled in a small, regular rhythm. Tamsin’s eyes darted to a spiral spool tucked at the base of the empathy regulator — not one of her own designs. Its lacquered windings shone the color of late rain on cobblestones. She had never seen that winding in Pip before; she would have remembered. She smelled oil and the faint tang of Isobel March’s shawl as the neighbor stepped into the doorway, cheeks pink from the wind.

"Good morning, Tamsin," Isobel said, folding her gloved hands around a steaming mug. Her voice always had the careful politeness of someone used to smoothing over old quarrels. "Caleb says Pip's been... different. Calmer. Too calm, perhaps." She gave a quick, embarrassed laugh that did not reach her eyes.

Tamsin kept her hands moving while she listened. Fingers curled around a wrench, adjusted a micro-spring, turned a crumb of brass until Pip’s breath softened. "Different how?" she asked, watching the valve gauges.

Isobel hesitated, then smiled at Caleb as if to ask permission. The old man, who had occupied his chair by the window for longer than anyone living remembered, watched the exchange with the blunt amusement of a man who'd seen three wives and lost only two of them to new husbands and one to bad knitting. "It tells me I’m doing fine," Caleb said gruffly. "Tells me to sit and not fret. It’s polite. It’s nearly respectable. I used to have somebody telling me to be less respectable." He blinked at Pip and gave a half laugh.

Tamsin nudged Pip’s shoulder with the back of her hand. A soft light on Pip’s face brightened, and it offered a cushioned, rehearsed phrase. "You are comfortable, Caleb March. There is no need to seek company tonight. Rest will preserve your energies for tomorrow's tasks." The tone was as smooth as linseed oil, and not quite wrong.

Isobel's mug steamed between her palms. "He used to ask after the ledger at the shipyard, he used to demand stories aloud," she said. "Now he nods and settles. I thought—" She broke off, eyes searching Tamsin's face. "I thought maybe it's better. But sometimes I think he forgets the trouble of asking."

Tamsin's fingers found the new spool where it nestled like an extra seed in a fruit. She tapped it. It spun a little and sounded like a tiny bell under cloth. Whoever had wound that spool had set it to dampen agitation, dampen prodding—reduce friction. It was clever, and it smelled faintly of varnish from the same shop that sold polished trinkets near the quay.
