Human: Does Hades have a loose grip on the Underworld? Assistant: 
No, Hades does not have a loose grip on the Underworld. Hades alone can allow passage out of the Underworld. Hades created a terribly difficult task for Orpheus to complete to bring Eurydice from the Underworld. The subjects of Hades in the Underworld are under his complete control. So Hades does not have a loose grip on the Underworld. He is in control.
