The name of the Greek god of the underworld is Hades. In Greek mythology, Hades rules over the realm of the dead, which is also called Hades. He is one of the three principal gods, along with his brothers Zeus and Poseidon. Although often depicted as a fearsome figure, Hades is not considered evil; instead, he embodies the inevitability of death and the importance of the afterlife. Hades is often associated with wealth, as precious minerals lie underground, and his domain is filled with souls rather than riches. He is also known for his abduction of Persephone, which symbolizes the seasonal cycle.
