Acheron

Acheron, in ancient Greek mythology, is one of the five rivers of the Underworld, often called the River of Woe. It symbolizes pain and sorrow, and souls of the deceased are ferried across it by Charon to reach the realm of the dead. The river's name has also been adopted in literature and popular culture to evoke themes of despair, transition, or the boundary between life and the afterlife. It serves as a metaphor for profound grief or suffering, representing the crossing from mortal life into the afterlife or emotional hardship.
