This story is entirely fictional. In Blue Bay, fishermen often hear a bell tolling beneath the surface when the sea is calm. Mira and Banu decide to investigate aboard a small submarine named Purnama.
Chimes from the Depths
Toward evening, Purnama leaves the dock carrying a searchlight, marker ropes, and two spare air tanks. Mira pilots the submarine while Banu watches the monitor. They follow the sound, which comes every few minutes: one long chime, followed by two short ones.
As they venture farther into the bay, the sunlight fades into thin blue shafts. There are no strong currents, and no large fish can be seen that might be striking the bell. Yet the sound grows clearer through the submarine’s walls. Ahead of them, the silhouette of a wooden ship appears, lying among a garden of pale coral.
The ship’s name is still legible on its hull: Layar Senja. Its mast has broken, but a brass bell still hangs from a crossbeam above the deck. Strangely, the clapper moves on its own even though the surrounding water appears almost completely still. Mira records the pattern of the chimes while Banu activates the observation camera.
The Message Behind the Rhythm
They leave Purnama in diving suits and approach the deck. As Mira touches the bell rope, the ringing suddenly stops. A small silver fish darts out from behind the bell. It swims toward the cabin door, pauses for a moment, then circles them again as if asking them to follow.
Inside the cabin, they find a glass box sheltered beneath a table. The box is unlocked. It contains no treasure, but rather a copper plate engraved with a pattern of dots and lines. Banu quickly realizes that the pattern on the plate matches the rhythm of the bell. One long chime indicates the main passage, while two short chimes mark a turn.
When they return to the deck, the water begins to fill with fine grains of sand. An underwater current slowly flows from a gap in the coral, reducing visibility. They now understand that the bell is not moved by the wind. Beneath the crossbeam is a small wheel connected to thin blades. The current from the coral gap turns the wheel, which then moves the bell’s clapper. The shipwreck has become a guide that operates with the flow of the water.
The Hidden Coral Passage
Mira and Banu return to Purnama and follow the directions on the plate. They pass through a narrow corridor between two coral walls. Whenever they are uncertain, the distant sound of the bell helps them choose the correct turn. At the end of the passage, they find a dome-shaped underwater chamber where tiny bubbles rise from the sandy floor.
At the center of the dome stands a miniature lighthouse made of green stone. There is no flame at its peak, but its surface reflects Purnama’s light in every direction. The reflections reveal a row of symbols on the wall: images of a ship, a bell, currents, and the bay. Banu concludes that the sailors of Layar Senja deliberately installed the bell mechanism long ago so the safe route could still be found when the water turned murky.
Suddenly, the current changes direction. Sand covers the entrance to the passage, making the route home look different. Mira remains calm and asks Banu to remember the pattern of the chimes. They switch off the engine for a few moments so they can hear the distant sound more clearly. One long chime directs them straight ahead, while two short chimes mark the gap leading to open water.
The Guardian of Blue Bay
Purnama finally emerges from the passage as night begins to fall. Behind them, the bell of Layar Senja starts ringing softly again. Mira takes the copper plate to study it, but then changes her mind. She returns it to the glass box because the directions are part of the ship and may still be needed by other explorers.
Before returning to the surface, they place a glowing marker at a safe distance from the wreck. The marker does not interfere with the bell mechanism, but it can warn divers not to touch the coral or enter the passage without preparation. The silver fish they encountered appears again, swims around Purnama, and then vanishes behind the deck.
When they reach the dock, Mira and Banu do not describe the bell as haunted. To them, the mystery instead reveals the ingenuity of sailors from long ago and the way the sea preserves a message. From that night onward, the chimes from Blue Bay are no longer regarded as a bad omen, but as the voice of a guardian showing the way beneath the waves.
