Caspian Tideborne swam along the coast for the third day, hunting for anything he recognized. He wanted only one thing: to find the person who could tell him his name. But the shore gave him nothing. Every cove looked the same. He had woken on a beach with no memory, no map, no idea which direction his old life lay. Without a landmark, he could only drift. He rested in the stone grotto he had claimed as a home. Green moss dripped down its old walls, and the arched mouth held back the current. He had slept here since the first night. It felt safe, but it told him nothing about who he was. He turned his left palm up and traced the scar there again. Nothing came. His tail caught the light from the grotto mouth. The dark green scales showed their gold edges. He stared at the gold, the way he always did, waiting for it to mean something. A soft blue glow drifted through the entrance. His pet jellyfish, the one that followed him everywhere, pulsed at the water. Its bell flickered blue and yellow. It bumped against a shelf of rock near the back wall, then bumped it again, insisting. Caspian swam closer. Something was wedged in the crack behind the shelf. He worked his fingers into the gap and pulled. A gold arm cuff came loose in his hand. He turned it in the dim light. Waves curled across its surface. A shell sat at its center, ringed by small painted shells in blue, orange, and green. He had seen this gold before. It matched the gold on his tail exactly. His chest tightened. This had washed ashore with him. He was sure of it now. Someone had made this, someone who knew the same craft that marked his own scales. This was not a lucky find. This was a thread back to his past. He pressed the cuff onto his arm. It fit as though shaped for him. The jellyfish circled close, its light steady now, calm. Then Caspian saw the marks. Along the inside edge ran a line of carved symbols, worn but clear. They were not shells or waves. They were writing. A place, or a name. He could not read them. But someone could. Someone had carved this by hand, in a real place, with a real name. For three days he had drifted with no direction. Now he held one. Caspian gripped the cuff and swam out of the grotto into open water. The coast still stretched blank in both directions. But he no longer searched for any shore. He searched for whoever knew this writing. He turned into deeper water and started to swim, faster than hunger, faster than doubt, toward the first true clue to his name.

Caspian found the wreck at the bottom of a cold trench. Its hull lay half-buried in sand. Broken planks jutted from the sides, and rust bled from old iron plates. A crooked mast still stood, wrapped in rope gone soft with age. He swam a slow circle around it. Through a round porthole, gold flashed. He pressed his face to the glass and saw a trident inside, its handle carved with shells and waves. The same waves curved on his arm cuff. His heart pounded. The answers were in there. But every hatch was sealed, swollen shut by years underwater. He pushed and pried until his fingers ached. Nothing gave. He surfaced and swam to the coast for help. On a rocky shore he found a man dragging salvage from the tide. Gray beard, blue coat, a brass compass swinging at his chest. The man hunted wrecks for a living. Caspian had heard the fishermen speak of him, half in fear. "There's a wreck below," Caspian said. "Sealed tight. I need it open." The man barely looked up. "Everyone needs something open. Costs." He named a price Caspian could not pay. Then his eyes caught the gold on Caspian's arm. Something shifted in his face. "Or that cuff." Caspian's hand closed over it. "No. This isn't for trade." The man studied him, then reached into his salvage and pulled out a heavy iron crowbar, streaked with rust. "Then you'll do the work. I don't dive anymore." He held it out. "Bar goes under the hatch lip. Pry from the corner, not the middle. And boy—if that ship is what I think it is, I want first look at what's inside." Caspian took the crowbar and dove. He wedged the flat end under the main hatch and threw his weight against it. Wood groaned but held. He remembered the man's words and moved to the corner. He set the bar and pushed again. A crack split the seal. Silt clouded up. He worked the bar along the edge, prying inch by inch, until the hatch tore free and drifted down. The way in was open. Caspian swam inside. He reached the trident and lifted it. Symbols ran along its handle—the same carved marks as the cuff. He turned it in the dark water, sure now that both had come from one place, one maker. This was his. But the crowbar had done more than open the hatch. Behind the trident, the pried wood had loosened a whole section of hull. The wreck shuddered. Beams cracked overhead. Sand poured in as the ship began to fold in on itself. Caspian clutched the trident and kicked for the opening. The hull sagged behind him, sealing the deeper rooms he had not yet searched. He shot out into open water, trident in hand, the wreck collapsing at his tail. He had his prize. But he could not carry it far, and the man on the shore was waiting to claim it.

Caspian broke the surface with the trident in his fist. The salvage hunter waited on the rocks, gray beard wet with spray, brass compass swinging at his chest. He hunted wrecks for a living, and Caspian owed him first look at whatever the ship held. "It's open?" the man asked. Caspian shook his head. "It fell in. The deeper rooms are buried." The hunter's face went hard. "Then you owe me a wreck I can't reach. I don't wait long, boy." Caspian gripped the trident tighter. "I'll dig it out. Give me until dark." The man crossed his arms. "You've got that long. After that, I collect another way." His eyes moved to the gold cuff on Caspian's arm. Caspian dove before he could say more. The wreck lay folded on the trench floor. Sand had swallowed the caved hull. Caspian pushed at the beams and moved nothing. He needed a tool, and he needed help. He remembered a shape he had passed on the way down. Deeper in the trench, a giant octopus rested against a ledge. Its skin was the warm color of coral. Its wide eyes held a slow, patient weight, as if it had watched the sea for a hundred years. Half-buried in the sand beside it lay a pale shovel carved from whalebone, its blade broad and cracked at the edges. Caspian showed the creature his trident. He traced the carved waves on the handle, then the matching gold on his arm. He did not know if the octopus understood. But he pointed at the buried wreck and pressed his hands together, pleading. The octopus uncurled. It reached one long arm to the whalebone shovel and passed it to him. They worked together. Caspian drove the shovel under the fallen beams and pried. The octopus wrapped two arms around a sunken plank and pulled. Sand billowed up in clouds. A beam tore loose. Then another. The broad blade let Caspian clear the silt faster than his hands ever could. Slowly a gap opened in the collapsed hull. Caspian swam into the dark space. He felt along the shattered floor. His fingers closed on a small iron box wedged under a broken rib of the ship. He worked it free and pushed back out into open water. He surfaced at the rocks as the light went orange. He set the iron box on the stone. "First look," he said. "As we agreed." The hunter knelt and pried the lid. Coins spilled out, old and green with age. The man's shoulders eased. He ran the coins through his fingers and nodded. "That clears you." Caspian's debt was paid. But under the coins lay a folded strip of leather. The hunter lifted it and held it to the light. Marks were burned into it, the same shapes carved on the trident and the cuff. The man's eyes sharpened. "I've seen this mark before," he said. "On a living man."

The salvage hunter folded the leather strip and slid it into his coat. "Seen this mark on a living man," he said again. "But a name like that costs more than coins." His name was Silas Blackwater. He had helped Caspian reach the wreck, but he traded in wrecks, not favors. He turned and walked up the rocks toward his dock office, and Caspian pulled himself onto legs and followed. The office leaned on gray, salt-worn boards. Silas pushed the door and it dragged over the uneven floor. Inside, charts covered the walls. He sat and set the strip on the table between them. "I know the man who wears that mark," he said. "I don't hand strangers to old friends. You could be his enemy. You could be worse." "I don't even know my own name," Caspian said. "How could I be his enemy?" Silas smiled without warmth. "Every man says that. I said it once." He tapped the compass on his chest. "Give me a reason to trust you, boy. A real one." Caspian looked at the gold on his arm. The cuff was all he had, and he would not trade it. But he thought of the deep trench, of the ledge where the octopus rested. He remembered a pale gleam half-buried in the sand there. He had swum past it twice. "Wait for me," Caspian said. He dove from the rocks. His legs became tail, dark green flashing gold, and the water took him down into the cold. He found the ledge and dug where the gleam had shown. His fingers closed on something smooth and round. He pulled it free and rose fast. He dripped on the office floor and set it on the table. A pearl, large as an eye, shifting with soft rainbow light. Silas leaned close. His hard face cracked. "I've hunted forty years," he said. "Never pulled one like this." "I'm giving it to you," Caspian said. "Not trading. A man who means harm keeps what's rare. I'm giving it away." Silas turned the pearl in his fingers a long moment. Then he set it down and looked at Caspian straight. "Fair," he said. He drew a breath. "The man who wears your mark is called the Warden. He lives on the far island, past the black rocks. Two days' swim." He paused. "He knew someone lost at sea. Long ago. He never stopped watching the water for him." Caspian's chest went tight. "Does he know my name?" "If anyone does," Silas said, "it's him." Caspian gripped the edge of the table. He had a direction now. A living man who remembered a face swallowed by the sea. He picked up the leather strip, and Silas let him take it. "Two days," Caspian said. "Past the black rocks." "Go careful," Silas said. "The Warden doesn't welcome strangers either." Caspian stepped out into the falling dark and turned toward the water.

Caspian swam through the night. By dawn he reached the black rocks Silas had named. Past them, gray water stretched to a low island. He stopped and treaded water. Silas's last words dragged at him. The Warden does not welcome strangers. Two days' swim, and the man might turn him away at the shore. Caspian would arrive unknown, unannounced, with only a leather strip and a gold cuff. He could waste his one lead in a single bad moment. He needed to warn the Warden first. To send something ahead that said, I mean no harm, and give the man a reason to open his door. A gull landed on the nearest rock. It watched him with a sharp, patient eye, head tilted, feet planted like it waited for orders. It did not startle when Caspian drew close. Someone had trained this bird. He guessed it carried messages between the island and the mainland. He had nothing to write with, but he had things to send. He reached to his own throat, where a black pearl hung on a dark cord. He had found it in the wreck's silt and kept it without knowing why. It was rare, sea-dark, the kind of thing only a mer-person would carry. From his belt pouch he took a small charm carved like coral, worn smooth. Together they said what words could not: I come from the sea, and I come in peace. He tied both to the gull's leg with the cord. "Take these to the Warden," he said. "Tell him someone is coming." The gull shook itself, spread its wings, and rose. It flew straight toward the island and shrank to a white speck. Caspian waited among the rocks. Cold crept into him. He wondered if he had thrown his only tokens away on a bird that would drop them in the waves. Hours passed. The sun climbed. Then movement broke the water near him. A dolphin surfaced, close enough to touch. Its fins shone gold, and gilded lines rippled along its gray skin like waves. It circled him once, blew air, and swam a short way toward the island. Then it stopped and looked back, waiting. Caspian understood. The Warden had sent an answer. Not a refusal, but a guide. The pearl and the charm had been seen and known. He followed. The dolphin led him around jagged shoals and through a narrow channel he never would have found alone. It swam the safe path, the one that ended at the Warden's door. Caspian's chest ached with something close to hope. The dolphin surfaced in a quiet cove. On the shore stood a stone house. A figure waited at the water's edge, watching him come, holding the black pearl in one open hand. Caspian pulled himself onto legs and stood. He was no longer a stranger arriving blind. He was expected.
