What are the three places in the underworld?

It is divided into three subsections: the Elysian Fields, the Asphodel Meadows, and Tartarus. The Elysian Fields were for the good and heroic souls where they would be forever happy, similar to the Christian Heaven. Tartarus was where the evil and treacherous souls were sent to live out eternity in horrible punishment, similar to the Christian Hell. The Asphodel Meadows are for people who simply lived and did nothing amazing, but nothing bad enough to make them go to Tartarus.
