Rin Calder worked by the window because the wind liked company. The bench under the glass was a scatter of tarred cord, brass buckles, and scraps of cloth that smelled of smoke and seaweed. Aeralis lay outside in tiers: roofs like overturned bowls, gardens clinging to ledges, the pale teeth of the sky-bridges. Beyond the nearest cluster of isles the air fell away into blue so sharp it hurt the eyes. From the street below the harbor bells sent up notes that trembled with the currents and with the gulls that circled the moorings.
Rin's hands moved with the practiced hurry of someone who mended what everyone assumed they could replace. Fingers threaded a loop through a small ring, pulled the knot until it held and then, as always, tested the pull with a breath. The leather smelled of winter oil and old storms. A child from the lane stuck his head in and grinned.
'Got another one, Rin?' he asked, waving a ripped messenger kite like a damp flag.
'Always,' Rin said, without looking up. 'Bring it here. We'll stitch your courage into the skeleton.'
The boy laughed and ran off. Outside, a packet-barge hummed past, trailing banners. Rin had been an apprentice to Petra Mohr for seven years, and Petra had a laugh that could set every string in the shop trembling. Petra kept ledgers with a careful hand and a soft place for stray souls. She had taught Rin the names of knots and the peculiar temper of an aether-thread. People called Rin a maker: of courier rigs, of weather-wedges and child's kites that smelled of lemons and tar. But what mattered most was where Rin put her trust — not in plans or rulers, but in the feel of the wind across the palm.
The door banged open and Petra entered with a scrap of news and a scalp of worry on her face. 'The see-hands found a scrape on the northern lane,' she said. 'Sky-fire and a missing manifest. There's talk of an island gone where the Rook's Keep used to be.'
Rin's stomach leaned toward the window. The Rook's Keep was the tilted spire everyone pointed to when they wanted to say 'we've always been steady.' It made chartmakers comfortable. It made children believe some things did not move.
A whistle from the harbor sounded, low and odd, like someone trying to whistle a storm into a jar. Down the lane came Joss Varr: a pilot with ink stains on his sleeves and a grin that made trouble sound like an invitation. He did not smile now. He held a folded sheet of blue paper that trembled in his fingers.
'They say the anchors shook themselves loose,' he said. 'A stitch in the old heart failed.'
Petra folded her hands. 'The Bureau will say it's a fluke,' she said. 'But storms don't pick sides. And missing manifests mean people too.'
Rin caught the word and let it settle like a pebble in her palm. A missing manifest could be a ledger error. It could be nothing. But it could be someone who never walked back through the door. The rope looped in Rin's hand suddenly felt thinner than it should.
They went downstairs together into streets of boiling smells: roasting brasscakes, the sweet rot of coriander, and the metallic tang of sailing iron. Merchants leaned over their stalls and argued about whether the sky would be steadier if you paid more for a bolt of silk. Children raced over rope ladders, swinging like playful gulls. Above them, a thin seam marred the sun: a silver line that made the light flicker as if the day itself had been stitched wrong.
Rin did not yet know that a single seam could unpick the world. She only knew the way the rope sang when it took a load, the small correctable noises that should be mended before they became a wound. She had been a mender all her life. The trouble was that this time the tear ran higher than any hand could reach with a needle.
