As Jack sailed back home, he couldn't shake off the feeling that his journey was far from over. The ancient scroll's revelation about the Golden Isle's true purpose lingered in his mind.
Upon returning, Jack's grandfather revealed a shocking truth: he was once a member of the Golden Isle's secret society, a group of visionaries who protected the island's knowledge and legacy.
Intrigued, Jack begged his grandfather to share more. The old man handed Jack a worn leather journal, adorned with strange symbols.
"This journal contains the society's history and secrets," he said. "But be warned, Jack, you're now a target for those seeking the island's power."
Determined to unravel the mysteries, Jack delved into the journal. He discovered cryptic messages, hidden codes, and sketches of intricate machines.
One entry caught his eye:
"Meet me at the old lighthouse on the night of the full moon. Come alone."
Was this a message from his grandfather or someone else?
