Styx is named after the river forming a boundary between Earth and the Underworld in Greek mythology.
=== Mythology ===In these myths, Styx supported Zeus in the Titanomachy, where she was said to be the first to rush to his aid
 Dante, putting Charon and the Acheron at the entrance to Hell, put Phlegyas as ferryman over the Styx and made it the fifth circle of Hell, where the wrathful and sullen are punished by being drowned in the muddy waters for eternity, with the wrathful fighting each other
