This story is a work of fiction with AI illustrations. Its characters and discoveries are imaginary.
This story is entirely fictional. Nara, a young submersible designer, is assigned to investigate a mysterious light emerging from the deepest trench in the Mirana Sea. Together with Bimo, her friend and an expert map reader, she sets out in a small submarine named Arunika.
A Glow Beneath the Darkness
The journey toward the trench is quiet. The deeper Arunika dives, the more the colors of the sea gradually disappear from the observation window. The vessel's lights illuminate only the dark water and fine particles swirling like dust in an empty room. Nara handles the controls while Bimo studies a map filled with fault lines and narrow valleys.
Suddenly, a blue light appears far below them. It pulses at regular intervals, glowing brightly three times before pausing. As Arunika draws closer, they see a large ship lying tilted on the floor of the trench. Its hull is covered in a shimmering layer, while its masts rise like towers from a forgotten city. Strangely, the light is coming from the ship's windows, as though lanterns are still burning inside.
Bimo finds a nearly erased name on the stern: Southern Lantern. The ship does not appear on the map they brought. Nara guides Arunika toward a wide opening in the hull. Before entering, however, she releases a glowing marker outside so they can find their way back if the current changes.
The Corridors That Still Sing
Arunika enters a vast cargo hold. There are no crates or valuables, only rows of glass pipes running along the walls. Blue light flows through the pipes like water. Each time the light moves, a gentle note echoes through the body of the ship. The notes form a short sequence, then repeat from the beginning.
At the end of the cargo hold, they find a round door bearing three symbols: a wave, a star, and the sun. Beneath them are three levers that refuse to move. Bimo listens to the sounds from the glass pipes and realizes that each note coincides with a change in the color of the symbols. The wave lights up first, followed by the star and then the sun. Nara presses the symbols in that order, and all three levers unlock.
They pull the levers together. The round door slowly slides aside, revealing an old wheelhouse that remains intact. In the center of the room stands a transparent sphere as large as a table. Light from throughout the ship streams toward the sphere, forming images of the sea, small islands, and a long golden path.
The Sea Guardians' Message
Beside the helm, Bimo finds an engraved metal disc. The inscription explains that the Southern Lantern once carried a device called the Map of Light. It was created to guide ships through fog and dangerous currents. When a great storm dragged the ship into the trench, the crew activated the device as a warning so that other sailors would not follow the same route.
But the Map of Light is now operating too powerfully. Its energy is causing the layers of rock around the ship to tremble, and the small vibrations are continually dislodging fragments from the walls of the trench. Nara sees a wheel-shaped control beneath the transparent sphere. To slow the device, the wheel must be turned at the same time as the three levers in the cargo hold. They cannot do both from the same place.
Bimo returns to the cargo hold with a communication device. Nara remains in the wheelhouse and grips the control wheel. They count together. As Bimo pulls the three levers in the order of the notes, Nara slowly turns the wheel. The transparent sphere shines intensely, then its light contracts into a single golden line pointing toward the way out of the trench. The rock stops trembling.
Arunika's Journey Home
When Arunika emerges from the shipwreck, the lights in the Southern Lantern's windows are no longer pulsing intensely. Now only a single blue lamp glows at the top of its mast. The golden beam from the Map of Light stretches across the seabed, passing through gaps in the rocks and leading toward safer waters.
During the ascent, a current suddenly pushes Arunika toward the side of the trench. Nara nearly loses her bearings because the marker they placed has been buried beneath sediment. Bimo quickly notices the golden line below them. By following it, they find a narrow passage sheltered from the current and manage to leave the trench.
After reaching the surface, Nara records the location of the Southern Lantern without taking anything from the ship. She and Bimo agree that the shipwreck is not a place to search for treasure, but a relic still carrying out its final duty. Far beneath the sea, the blue lamp continues to shine peacefully, guarding the trench while reminding anyone who comes near to remain cautious.
