Purgatory

Purgatory was a realm created at the beginning of time, Infernals were birthed from the Ancient corpse of Chaos and the infernal realms were ruled in chaos. It was only after Lucifer fell that Purgatory had a Hierarchy through power. However after god created the Earthly realm and Humans, after they died they would be sent to the afterlife and if they lived sinful lives or committed atrocities while living they would be sent to infinite torment.

Characteristics
Purgatory was said to be split into multiple circles due to the corpse of Chaos being shattered upon dying. These Circles were made up of 9 Realms connected to each other. Each Circle has a relation to a sin.

The Ninth Circle was said to be a state of Limbo for sinful souls to view Eden however unable to reach it, this circle was guarded by Imps and simple Demons. Celestial beings would often visit the Ninth Circle to torture sinful souls and save those who repent for the lives they lived.

The Eighth Circle - The Eighth Circle was said to be a circle for Lustful souls and a windy circle full of rot and decay. A violent storm would blow sinners away from whatever they lusted for in life, unable to reach what they want but are able to see it. The Eighth Circle is said to be alike the Ninth however for Lustful souls.

The Seventh Circle - The Seventh Circle is said to be a realm for Gluttonous souls, the cold icy violence of the environment within this circle was the breeding ground of demons with the powers of Ice and often see the souls of Gluttonous beings to be tortured through the violent cold.

The Sixth Circle - The Sixth Circle is said to be a realm for the Greedy, these souls were drowned in pits of Gold and had their eyes removed daily.

The Fifth Circle - The Fifth Circle is a realm for the Wrathful, this circle is a swampy land full of trees and water. The Souls of the wrathful fight in long unrelenting battles without end, tiring them out but not allowing them to stop. It is said once the war ends in this realm, it would collapse into the Fourth Realm.

The Fourth Circle - The Fourth Circle is a realm for the Heretical souls, those who did not believe in god or disregarded his teachings on how to live a virtuous life. The pit as it's referred to is where Hellfire originates and is a hot realm full of lava, volcanoes, demons, and the souls of the Heretics.

The Third Circle- The Third Circle is a realm for the Violent and Killers, anyone who killed in anger or vengeance were condemned to eternal burning suffering. These souls were surrounded in pits of blood and fed blood, they were often tortured to the point they became Demons themselves however they were released after coming into their power fully. It is rare that a soul from this circle becomes a demon however.

The Second Circle - The Second Circle is a realm for the souls who commit Fraud, they are sent to a pitch black realm of darkness and placed on chains. These demons would often torture these souls into becoming Demons, though the torment would take multiple millennia's to complete unless the soul gave into the corruptive nature of Hell easily.

The First Circle - The First Circle, also known as Pandemonium, is a cold realm where Lucifer and his Fallen angels were banished to after their fall. The high ranking demons were often found here in the icy castle located in the center of the realm, it was a place of infinite violent ice storms. The power of Hell was said to originate here, Lucifer acting as a battery to recharge it infinitely.
