Oh, so basically in my version of Hell, certain people that are sent down there AKA sinners are put in these orbs by the grand council of Heaven if they deem them too much of a threat. Sinners usually get a few powers when they get sent down, but ones with the strongest of wills and highest of powers and sins get more powers and are much more stronger. Due to this, the Council seals them in the layer known as Heresy, which they lock em up in these orbs. Each orb is different, as the apperance of the sinner, how they died, their profession, etc are main factors of the orbs appereance. Most are usually aslumber, but if a select few are woken up, they could break from their prison and most likely cause havoc.
