The term 'River of Myth' refers to two rivers in Greek mythology. The first is the Styx, a river that formed the boundary between Earth and the Underworld. It was said to be a river of hatred and was the only way for a soul to enter the Underworld. The second is the Neda, a river in western Greece that was said to be the home of the Nymphs. It was believed to be a source of inspiration and creativity.
