The underground lake felt smaller now, as if the walls were closing in with the weight of the secrets Kaito had discovered. He sat by the water's edge, clutching his father's journal. The leather was scarred and stained with seawater, but to Kaito, it was the most precious treasure in the world.
"The Sunken City of Eridia..." Kaito murmured, tracing the map with his finger. "It's located in the center of the 'Dead Zone'. No merchant ship or navy vessel dares to go there."
Oro, the Shell of Ages, slowly began to submerge his massive body into the glowing water. "The Dead Zone is not empty, Tide-Walker. It is filled with the echoes of those who failed. To reach Eridia, you will need more than just a boat. You will need a ship that can breathe."
Kaito looked puzzled. "A ship that breathes? What does that mean?"
"The Forbidden Sea does not like intruders," Oro explained, his voice echoing like thunder in the cavern. "It will try to crush your hull with pressure and freeze your soul with its depth. Go to the 'Shipyard of Whispers' on the northern coast of your island. Look for the blind shipwright. Tell him Oro has sent the Tide-Walker."
Kaito stood up, packing the journal and the mysterious silver vial into his bag. His shoulder still throbbed from the Lurker's attack, but the pain felt like a reminder—a reminder that he was no longer a victim of fate, but a master of it.
As he began the long climb back up to the surface world, the bioluminescent light of the cave started to fade. He emerged from the hidden entrance just as the first light of dawn was hitting the ocean horizon. The sea looked different now. It wasn't just a vast expanse of blue; it was a living, breathing challenge.
"I'm coming for you, Dad," Kaito whispered to the morning breeze.
He didn't go back to his village. He knew that if he did, the elders would try to stop him. Instead, he headed North, toward the Shipyard of Whispers. His journey had truly begun, and for the first time in years, the compass in his pocket didn't just point to the North—it pointed toward his destiny."Kaito felt the weight of his father's legacy pulling at him, a heavy but grounding force. The path ahead to the 'Shipyard of Whispers' was jagged and steep, but his resolve was now as firm as the ancient reefs. He looked back at the fading light of the cave one last time, knowing his life as a simple boy was over. With the silver whistle against his chest and the sea-wind in his hair, Kaito stepped into the unknown. The Forbidden Sea had found its master, and the journey had only just begun."
