In the shadowy depths of the underwater city of Aquaferra, a lone wolf named Kael swam through the silent streets. He had been trapped there for many years, ever since the surface world had become too dangerous for his kind. However, he had learned to survive by hunting glowing fish and hiding from the monstrous leviathan that patrolled the ruins. The city was beautiful in a haunting way, with its coral-covered towers and eerie blue light, but Kael often felt a deep loneliness.
One day, a young dolphin named Lira arrived in Aquaferra, separated from her pod during a sudden storm. She was frightened and exhausted, and she had been following a group of migrating whales when the current had pulled her away. Kael watched her from behind a broken statue, unsure whether to help or hide. However, when he saw the leviathan's dark shape approaching, he knew he had to act. "Follow me!" he barked, and Lira, trusting the strange wolf, swam after him into a narrow tunnel.
