Underworld
The mythic Relm of the Dead, located far underground (aka, Hades; Underworld)
Would Hades and Osiris hypothetically compete for real estate in the Underworld?
Hades was the Greek god of death and the Underworld. Osiris was the Egyptian god of the Underworld.
What was Hades the God of? What was Osiris the God of? Is there any overlap between #1 and #2?
