As they journeyed deeper into the island, they discovered that the artifacts were hidden in temples dedicated to the ancient gods of the sea. They found the first artifact, a golden amulet, in a temple filled with treasures beyond their wildest dreams. The second artifact, a pearl necklace, was hidden in a temple guarded by a massive sea serpent. And the third artifact, a crystal orb, was hidden in a temple that seemed to shift and change its layout every time they tried to enter.
