Forbidden Island

Centuries ago the Lycan were exiled from the mainland to live on what is now known as the forbidden island.
Alex left his home early for his day's fishing before the approaching storm hits, his fishing grounds are close to forbidden island.
As he dropped his last pots and lines into the sea, the storm was already upon him, forcing him to take refuge in a sheltered bay near the islands only beach.
He was about to drop anchor when he heard a baby crying, how was this possible over the sound of the storm , wind and crashing waves?
The cries were coming from a cave that had been exposed by the low tide, it would be underwater at high tide.
Using his magic to guide the stern of his boat into the cave, he saw a box sitting on a rock shelf close to a tunnel opening.
Reaching across, he pulls the box into his boat, the baby inside stopped crying and fell asleep, racing through the eye of the storm, he returns home.
The baby looks human but no humans are living on forbidden island.
Follow the baby as he grows.
Will he fulfil the prophecy? Is he the one?
