This story is entirely fictional. Nara and Bimo begin their dive near sunset after hearing a bell ringing beneath Lazuardi Bay. They have no idea that the sound will lead them to a shipwreck, a coral passage, and a message that has been waiting for a very long time.
A Sound from the Depths
The residents of Mutiara Island know Lazuardi Bay as a calm stretch of water. Yet for three afternoons in a row, a deep toll has sounded from the middle of the bay even though the air has been completely still. Passing fishermen say it sounds like a ship's bell, but no large vessel is anchored there.
Nara, a young diver who enjoys mapping the seafloor, invites her friend Bimo to investigate the sound. They bring diving equipment, waterproof lights, writing slates, and a coil of marker line. Before descending, they promise not to touch anything that looks fragile and to return immediately if conditions change.
The bay water feels cool and clear. Schools of small fish pass by like silver ribbons, while seaweed sways gently with the current. Amid these soft movements, however, a single long toll rings out. The sound travels through the water and reverberates in their chests. Nara points toward a dark shadow behind a coral hill.
The Ship in the Coral City
Behind the hill lies a wooden ship named Arunika. Its name can still be read on the stern board beneath a thin layer of moss. Its mast has broken and its sails are long gone, but a brass bell still hangs near the foredeck. No rope is attached to its clapper, and there is almost no current in the surrounding water.
As Nara and Bimo approach, the bell rings again. Its clapper moves on its own, as though pulled by an invisible hand. Bimo briefly retreats, but Nara notices something emerging through a gap in the ship's planks. Tiny bubbles rise in a steady rhythm, then gather directly beneath the bell.
They follow the trail of bubbles to the ship's hull. There they find a metal pipe extending into a narrow passage between the corals. Each time water pressure forces air through the pipe, a small rod moves and strikes the bell. The mysterious sound does not come from the wind or an unseen presence, but from an old device that is still working. Yet a new question arises: where does the air inside the pipe come from?
The Bay Keeper's Message
The coral passage leads them to a vast chamber with an air pocket at the top. Mounted on its walls are a stone wheel, metal channels, and a large spherical float. Waves from the other side of the island push the float through an underwater opening. Its movement pumps air into the pipe, causing Arunika's bell to ring.
Beneath the stone wheel, Nara finds a ceramic plaque inscribed with a series of simple images. The first shows a ship entering the bay. The second depicts sharp coral near the surface. The final image shows the bell ringing as the tide begins to recede. Nara understands its meaning: the bell once served as a warning to keep ships from entering the dangerous passage.
However, part of the air channel has cracked. The pressure that should produce a single toll now causes the bell to ring repeatedly. Nara and Bimo do not attempt to repair the old device for fear of damaging it. They only clear away a piece of seaweed blocking its outlet, then mark the location with a small buoy so it can be safely found again.
The Bell Returns to Its Steady Rhythm
When they emerge from the passage, the evening light pierces the surface like golden pillars. Arunika's bell tolls again, this time only once. A sea turtle glides above the deck, while small fish hide among the ship's railings. The wreck no longer looks frightening. It resembles an old guardian still carrying out its duty in the heart of the coral city.
Nara and Bimo return to the island and tell the residents what they found without taking a single object from the site. Together, they place a safe marker on the surface and agree that Arunika must be preserved as part of the bay. The fishermen also begin paying attention to the bell again as a sign of changing water levels around the shallow coral.
From that day on, the sound of the bell can still be heard near sunset. The difference is that the residents no longer close their windows or stay away from the shore. They pause for a moment to listen. For Nara and Bimo, every toll is a reminder that a mystery does not always need to be feared. Sometimes, it is simply waiting for someone to approach it with courage, caution, and curiosity.
