Underworld

In Greek mythology, the Underworld was a misty, gloomy, and volcanic realm where all mortals would be judged in the afterlife, either being rewarded or cursed. It can't, however, be called Hell, since even nice and virtuous souls were sent there after death, although The Underworld was split into different parts: there were several sections within the Underworld, including the Elysian Fields, the River Styx, and underworld created by primordial god called Tartarus. Heroes of the ancient time dwell in Elysium (Isles of the Blessed), ruled by the god, Hades.
