The Cavern of Souls, located on the River Styx in the Greek Underworld, is the birthplace of the Amazonian culture. For centuries, women who had died through acts of violence found their souls transformed into streaks of light and they became part of the Cavern of Souls. Over a thousand years ago, the Olympian Goddess Artemis petitioned her fellow Gods to form a new race on Earth - a race of women who would usher in a new era of greatness mankind and re-invigorate worship in the Gods. Zeus had no interest in Artemis' plans, and Ares felt that such a venture was foolish. Without Zeus' consent, Artemis and several other Gods traveled upon the River Styx to the Cavern of Souls. There, they freed the disembodied souls from the Cavern and transposed them on Earth. These souls were reincarnated in new bodies and they eventually became the Amazons of Themyscira.
