The term 'HERO' in this crossword refers to the Greek mythological figures of HERO and Leander. HERO was a priestess of Aphrodite who lived in Sestos, while Leander was a young man from Abydos. The two were deeply in love, but due to the distance between them, Leander had to swim across the Hellespont every night to be with her. Unfortunately, one night he drowned in the strong currents and HERO died of grief shortly after.
