The epic story detailing how thousands of years ago Starswirl the Bearded defeated the Sirens and banished them from Equestria, how they were exiled to the Mediterranean island of Capri, and what happened next.

“You will come to the Sirens first of all; they bewitch any mortal who approaches them. If a man in ignorance draws too close and catches their music, his wife and children will never welcome him home again; the high clear tones of the Sirens will bewitch him … you must stop the ears of all your crew with sweet wax that you have kneaded, so that none of the rest may hear the song.”
Homer
