Hollow Wall Tenant

The hollow wasn’t metaphor until Selene’s knuckle found it: a hairline seam where gutter-storm glass had been set too thin, cooling faster on the stair side than on the harbor wind. When she tapped, the niche answered with a deferential tick—glass remembering someone else’s knock.

The listener pressed their rented spine to the riser, catch-pole ring forgotten. "Who hollowed it?" they asked, not to Selene, to the storm glass.

"Someone who paid in drafts," Selene said, "not in stamps." She didn’t offer her mirror; she offered alignment—palm flat, breath shallow—until the jury of harmonics leaned toward curiosity instead of indictment.

Jace fed the rig a line that wasn’t theater: coordinates scraped from the false timetable’s slack, the kindness that still rolled above them. The stylus bit wax; the Syndicate’s distant ear would hear a cargo lane waking early—useful noise if you wanted clerks looking at hulls while feet disappeared through seams.

The listener’s mouth shaped a Syndicate oath and spat ash instead. "If I go through," they said, "my sponsor eats my name."

"Then take a new one," Selene murmured. "Tenancy is paperwork until it’s air."

She widened the seam with a thumbnail’s patience—mirror-school precision turned to burglary of light. Behind the glass, draft smelled like salt and old varnish: a maintenance crawl not on any charter map Jace had signed.

He logged it anyway. "Echo routed," he whispered to the horn, not for the Syndicate—for the stair, for the ledger his ribs kept when ink lied.

Above, rollers grumbled their pretend weather. Below the hollow, something softer answered: not footfalls, not hymn—a second crawl remembering the First Ley Surge the way understairs remembered heat left behind.

Selene slid into dark first because leaders learned which blade wasn’t theirs by pressing flesh to it. The listener followed because rented bodies learned survival faster than sponsors approved.

Jace capped the horn, tucked the rig, and became the last echo anyone upstairs would assume was machinery—a steady wrong cadence until the stair believed its own rumor.
