Styx

The River Styx (Greek: Στύξ, Stux, also meaning "hate" and "detestation") was a river in Greek mythology which formed the boundary between Earth and the Underworld, Hades. It circles the Underworld nine times. The rivers Styx, Phlegethon, Acheron, and Cocytus all converge at the center of the underworld on a great marsh. If happen to have a few cents when you visit, you could even get a ride from Charon The ferryman.

Styx is also a band from Chicago.

Thumbs up!
