In Cosmology and Mythology, the Underworld is typically the lowest of the 3 Worlds. It is sometimes further subdivided into further worlds or hells. Other names for the underworld are Hades, Hel, Hell. It is also called the the House of Underworld (Calli) or the Netherworld (Anderodumnon). Most cultures have a God, Goddess or a King of the Underworld. In many cultures this underworld is threefold: 1) Underworld in General 2) Underworld as under Earth and Wealth under Earth (minerals, gems) 3) Underworld as place of death, burial and judgement. This leads to a Lord of Wealth and a Lord of Wealth of the Earth who is typically distinct from the Lord of the Earth. All of these functions have gods with spicific names in different cultures.
