Hades
King of the Underworld, Wealth, Justice, and Mercy.

Hades is the King of the Underworld in Greek mythology, also referred to as Pluto.
He governs the realm of the dead, a world teeming with the souls of the departed. While Hades does not belong to the Twelve Olympians who sit upon the golden thrones of Olympus, he is one of the Three Great Gods alongside Zeus and Poseidon.

To the ancient Greeks, Hades and Pluto were considered the same deity, but their names emphasized different aspects of his dominion.
When speaking of death and justice, the name Hades was used. Conversely, when referring to wealth and mercy, the name Pluto was invoked.
Because death and the Underworld were deeply feared concepts, official state documents and records predominantly used the name Pluto rather than Hades.
