When he encounters Nileas, the first man to heed his warnings in time to be saved, Aeolus at last has a chance to indulge his fascination with the world of men. As they begin the long journey back to Nileas's home at the other side of the Mediterranean, sharing stories of their respective lives, it becomes apparent Nileas is just as fascinated with the world of the seaand with the merman who saved him.
