Chapter 1: Shores of Memory

An isolated island, a jewel of white sands and lush emerald forests, lay serene in a crystal-clear, light blue ocean. Its tranquility shattered as a boy, barely more than a child, washed ashore. His jet-black hair, shimmering with dark blue highlights, contrasted sharply with his tanned skin, a testament to harsh sunlit days. His clothes, simple and torn, offered little protection to his pale, fragile body.

Waves crashed, time passed, until suddenly, his eyes snapped open. He sat up, bewildered. "Where am I? More importantly... who am I?"

Calmness settled as he realized no immediate danger. He closed his eyes, searching for answers within his own mind. A jolt of surprise. "Huh?!" He sprang up, pacing the beach, hand on his chin. "Have I gone crazy?"

An existential crisis brewed: two distinct sets of memories. One belonged to a blue-eyed man in a world of towering buildings and advanced technology. The other, to a green-eyed boy from a harsh, deadly place of wooden huts, disease, and bandits, devoid of modern conveniences.

He knelt by the water, gazing at his reflection. Sparkling green eyes, like purest emeralds, stared back. "So, I'm the one with green eyes," he murmured. "A giant squid, a kraken even, attacked us... But that's not important now. Survival is."

He scanned the imposing forest behind him. "Going in there is a bad idea. No weapons, no gear. I wouldn't last a day with predators inside. Time to remember the old man's teachings."
