In Greek mythology, Lethe is the name of a river found in Hades (the Greek name for hell). Greek mythology says those who drink from this river forget everything. In Spellbinder/ Enchantress, Thea Harman and Eric Ross are asked to drink from the Cup of Lethe so that they forget the Night World exists.-- Back.
In Classical Greek, Lethe (Î»Î®Î¸Îµ; LEE-thee) literally means "forgetfulness" or "concealment". The Greek word for "truth" is a-lethe-ia (Î±Î»Î®Î¸ÎµÎ¹Î±), meaning "un-forgetfulness" or "un-concealment".
