When I saw herione* my brain jumped straight to Hermione Granger, the heroine from J. K. Rowling's Harry Potter series.
Or, perhaps, Hermione from Greek mythology, the daughter of Menelaus and Helen of Troy. The Greek Hermione's name is also spelled Ermione, which at first looks like an error without the H, in Gioachino Rossini's opera Ermione.
Herione* is, however, more likely a typo for heroine*, which is how it's used in the majority of its 56 hits in WorldCat.
