PLUTO
After the great war when Zeus overthrew his father Cronus and claimed the sky, his brother Hades was given dominion over the underworld—a vast realm beneath the earth, home to the souls of the dead. The underworld held five great rivers, and all souls crossed the river Styx, ferried by Charon, who demanded a coin for passage.
