Tartaros

This name derives from the Ancient Greek “Tártaros (Τάρτᾰρος),” meaning “the darkest, deepest part of the underworld.” In Greek mythology, Tartaros is the deep abyss used as a dungeon of torment and suffering for the wicked and as the prison for the Titans. In Greek mythology, Tartarus is both a deity and a place in the underworld. In ancient Orphic sources and the mystery schools, Tartarus is also the unbounded first-existing entity from which the Light and the cosmos are born. In Roman mythology, Tartarus is the place where sinners are sent. Virgil describes it in the Aeneid as a huge place, surrounded by the flaming river Phlegethon and triple walls to prevent sinners from escaping.
