Reign of Angels
The divine creator presided over the mortal realm and he delegated the realms of the afterlife to his five archangels. Despite bearing the title archangel, they were more akin to gods. Each archangel could do anything the creator could do.
The infamous fallen angel Lucifer presided over the abysmal depths of Inferno and Archangel Uriel, the divine judge, was tasked with guarding its gates. Heaven was left under Archangel Michael's eye, for he was the creator's most trusted confidant.
Meanwhile, Archangel Gabriel and Raphael shared duties. Both of them oversaw Mount Purgatory, the place where lost souls traversed to in hopes of achieving salvation. They would assist souls that they deemed were worthy and then proceed to guide them in the realm of Utopia.
Utopia was the lesser known of the four realms in afterlife. Often times, purgatory wasn't enough to cleanse one's sins. Affairs in the mortal world had a penchant for preventing souls from reaching heaven and the only way for that struggle to cease was divine intervention in the mortal realm.
Utopia gave lost souls the opportunity to travel back to the mortal realm. It held a theater that allowed them to witness and influence the actions of their reincarnations. This was their opportunity to reverse their grave mistakes and finally ascend into heaven.
At least, that's what Archangel Gabriel and Raphael preached. It wasn't that simple.
If one succeeded in reversing their mistakes, they were permitted to go into heaven. However, they were not given the luxury of basking in heaven's ammenitities. They were turned into saints- guides for lost souls. Saints would take on the duty of accompanying residents of Utopia and helping them achieve their roles.
Humans were arguably the most influential beings. They were sculpted in the Creator's image and given free reign of their lives. They had no obligations to the Creator. Their circumstances and luck were the only things shaping their lives. That was, if their lives weren't being influenced by their past selves.
More often than not however, it was.
