Ewei

Story
Ewei is a mage that resides on the Isle of Evil who is in possession of the Emerald of Evil. 50 years before the events of the game he captured a ship of passengers and used them in an experiment. He does succeed in giving his subjects eternal youth but at the cost of putting them in a deep irreversible slumber. One of his subjects escaped and returned to the mainland, Ewei was humoured at the aspect that one was able to escape and he placed a spell on him to act as a key to navigate the storm around the Isle of Evil. In the western release of Romancing SaGa, he just cast a spell to disperse the storm which still remains. He infused himself with the cells of monsters to slow his aging so that he can continue his experiments unfettered.
