Question regarding the event. I'm having Zero take on the powers of Hades and have him believe the Underworld is basically his home. As keeper of the Underworld is it possible for him:

1) Call on dead spirits of people in Adstring? By that I mean, speak to them and basically order them around in the confines of his place of residence.

2) Have complete control of the Underworld (confined to his place of residence), so he may keep someone confined inside if he wills it?
