Orrery Card

An orrery card is what remains when a decommissioned hearing model donates a slice of its sky. Cut from the equatorial ring of a Syndicate orrery—never from a floor model, never from a night-shift foundry rig—the disc is palm-wide, brass-rimmed, and faced with obsidian glass ground to the same ratios as the parent instrument. Guild charters call it a listening plate in miniature; auditors who carry them in witness bindings call it the only honest page in a deposition.

The card does not turn like a full orrery. Its planetary markers are etched, not geared; drift is read by hum, not slippage. When moons on the etching settle into the posture auditors name listen, do not litigate yet, the brass rim vibrates once—a note felt through the binding's leather more often than heard. Counsel who mistake the hum for theater learn quickly: the Syndicate treats a card that fires mid-oath as grounds to reset Saturn and begin the schedule again.

Manufacture and assay

Cards are not forged fresh. They are retired into service: when a hearing orrery fails quarterly recertification or develops opinion drift, the equatorial ring is furnace-audited, witness plates destroyed, and one or two sound sections set aside for card stock if the brass still remembers honest ratios. Apprentice card-cutters work under live stability fields thin enough that a slip of the graver becomes a career.

Each finished card bears three marks: the parent orrery's assay sigil (quarter and district), a perforation comb keyed to harbor lockstep docket spacing, and a binding clause etched on the reverse in pulse-ink that remembers whose witness book may host it. Cards without binding clauses are contraband in deposition rooms—pretty brass, illegal grammar.

The listening rig

Jace Morrow's rig is the reference design cited in Syndicate margin notes: orrery card sewn into the witness binding, spent orbital witness plate in the pocket, secondary dial keyed to speech rate clipped to the book's spine. The card hums; the plate proves where the heavens stood at the first syllable of an oath. Morrow's receipt-hush method pairs the two unsettlingly well—paper rows for the gears, breath held until the hum permits argument.

Rigs vary by auditor taste. Some add storm-glass samples from cliff racks; some wire sigil-stability strips to the binding's clasp. The card remains non-negotiable: without it, a listening rig is merely a notebook with ambitions.

Charter use

In depositions, the card enforces pause grammar. When testimony outruns Mercury—skipping steps, double-entering motives—the hum fires before the hearing bell. Clerks mark the moment on secondary dials; judges may ask one question only, phrased without metaphor. Cross-examination that introduces a new moon without resetting the witness plate is void whether or not the card fired; the hum is courtesy, not mercy.

Harbor lockstep adopted cards for collective testimony: crew statements chained like rosary beads, each voice inheriting Saturn from the last. When one bead warms out of phase, the card in the auditor's book hums and the whole chain returns to the dock—a practice borrowed from deposition rooms after the Glass Consensus proved triads and torque spoke the same language.

Failure and forgery

Cards fail in ways gears forgive slowly. Thermal creep in a sun-warmed witness room detunes the hum until honest men sound like liars. Salt fog throws Venus into false affection; auditors wipe the glass and rehear. Forged cards—cut from floor-model slag or stamped with imitation assay sigils—are melted on discovery; harbor clerks carry magnifiers calibrated to equatorial tooth pitch the way coiners once did.

A card cut from an opinion-drifted parent is the worst forgery of all: it hums for nightmares. Retired rigs are furnace-audited even when no crime is suspected, because brass remembers hands and stories outlive tellers.

Superstition and trade

Dockside slang calls a spent card a sky that learned to shush. Smugglers price them in rumors; auditors price them in seasons survived without reversed perforation. The Iron Syndicate licenses card-cutters the way it licenses storm-glass harvesters—assay first, argument later.

Honest auditors oil the rim with graphite and a trace of salt from old contracts, the same superstition that keeps full orreries patient. It works often enough that the practice persists. When the hum fires and the room stills, even liars feel the miniature heaven on the table asking for one sky at a time.
