The Lethe River, also known as Lete River, is a river in Final Fantasy VI that flows through the World of Balance. It starts in the Sabre Mountains and flows through the mountains and has two discharges: one near the port city of Nikeah and the other is near Gau's father's house. The river runs into a lake close to Narshe. It passes by the Returner Hideout, and the Returners built rafts to escape in an emergency. The river, along with most of the Sabre Mountains, is gone in the World of Ruin and appears to have sunk beneath the ocean.
