Fresnel Room
Fourth-order lens, twelve brass prisms, one cracked bullseye kept for calibration. Polished at dusk with whiting paste and linen cut from retired signal flags.

PHAROS
A lonely lighthouse service for ships that arrive late, names that must be remembered, and weather that writes in white water. Tonight the lantern is not a symbol. It is a working sentence.

Keepers of a coast that disappears by habit.
PHAROS maintains seven remote lights, three bell buoys, and the foghorn house at North Marrow Head. The station is small enough that every duty has a name, yet exact enough that a missed minute becomes a story told in court.
Diaphone House
Compressed air horn tuned to C below middle sea. The first note carries low under the fog; the second arrives higher, like a door opening offshore.
Harbor Watch
Barometer, tide staff, black-glass rain gauge, and one red telephone that rings only when a vessel reports the light by name.
Mail Boat Ritual
At 09:40 on fair Mondays, the launch brings diesel, bread, weather forms, two newspapers, and any letter brave enough to cross a breaking inlet.
Light-characteristic editor / write the rhythm
Compose a signal and the lighthouse obeys it live.
A ship identifies a light by rhythm before it sees the tower. Build a characteristic below: flash group, color, period, and cadence. The beam above follows your order as if the keeper has set the clockwork by hand.
Current characteristic
Station lantern: three white flashes, fifteen second period.

Shipping forecast / 2310 UTC / read twice, signed once
Meteorology in shorthand, poetry by regulation.
Sea smoke combing the outer reef. Bell buoy No. 4 heard at irregular intervals, likely masked by breaking swell.
Two trawlers sheltering under the lee. Green sector visible when fog lifts above chapel roof.
Harbor master requests red sector check after gull strike on lower gallery glass.
Use sound signal before entering the gut. The old wreck buoy is reported ten meters south of charted position.
Keeper's log / vellum sheets dried by the stove
The island keeps time in flashes, knocks, and wet boots.
Lens lit under a red sky.
Miss Venn reports a warm bearing on the upper spindle and has marked it for the morning oiling. Three gannets circled the gallery during lighting and left without striking glass.
Foghorn test carried clean.
Two notes. Echo returned from Kettle Scar in twelve seconds. The second note set the pantry cups trembling but did not wake Calder, who sleeps like ballast.
Unknown vessel answered.
A small white flash three points south-west, then no reply. Logged as possible deck torch until the tide master confirms departures from Black Yawl.
Fog climbed the stairs.
Condensation found on the fifth landing inside the tower. Wiped brass rails, checked gallery latch, set the kettle back. Light remained visible in the service mirror every revolution.
Watch roster / relief due on the fair Monday launch
Names behind the beam.
Mara Venn
Fifteen winters at North Marrow. Can judge visibility by the sound of the stairwell door.
Jonas Calder
Maintains the horn compressors and keeps an exact private map of every leak in the roof.
Etta Roan
Writes clean figures in violent weather. Invented the red wax tags used on faulty buoy chains.
