You wake with the taste of salt in the back of your throat and the slow beat of the city under your ribs. Aelion is not a city of streets but of channels and glass arteries; morning light arrives as pale bands through the dome and makes the suspended gardens glow like stitched lanterns. You swing your legs over the edge of the bunk carved from driftwood and listen for the ledger's hum. It is quiet now, sleeping in its cradle beneath the archive bench, but you know its weight by memory. You press your hand to the bench where the ledger sleeps and feel the faint vibration, like a heartbeat that records tides instead of blood.
The archive smells of wet paper and copper and the faint tang of kelp tea that Maren always forgets to finish. Shelves curve and stack in vaults that ache with compressed evenings, each shelf a record of currents, storms, a grandmother's whispered promise. Your apprentice tools hang on a peg: a slender pricker to tease out trapped memories from ledger seams, a coil of luminous thread for mending worn pages, and a small brass key shaped like a fishbone that only you can turn. You tighten the strap of your work vest and test the key between thumb and finger, listening to the city breathe.
Maren finds you before you leave the archive proper. She appears at the doorway like a remembered tide, bent with spines of barnacles and hands freckled with old ink. Her voice is low, the way heavy things make a sound when rolled: 'You took the night watch, yes? The ledger feels restless when not held by a tidewright.' You nod. You have always wanted the ledger close enough to read its scratches, to see the way it remembers the sighs between storm and calm. Maren watches you smoothing the luminous thread across your palm and says, 'Remember what it does: holds memory and current. It keeps Aelion from forgetting how to be itself.'
You step into the vault proper. The domed ceiling is a map of glass, and when you look up you see fish like glinting coins, the city a constellation arranged by hands that loved order into pattern. Below, the Archive hum runs along the floor in faint ridges; you follow it like a muscle that knows the old work. In the corner, a small basin murmurs, and inside the basin a mechanical seahorse rotates, polishing itself with patience. You feel the ledger's presence under your palm as a warm, watchful animal. For now, the city keeps its promises, and you keep your watch.
