Hell. The prison for the damned, a realm of fire and brimstone. It was a place only evil people ever entered, however it had its limits.
When Lucifer crashed down to earth, the impact of the once Celestial being created a massive crater deep enough to puncture right through the earths crust. This, combined with what little Celestial energy he had left, began his prison for the damned. He made an agreement with God, to house all the wicked in the world, but he would have total control over hell and how it was run. God would have no real say in the punishments that took place down there.
Once the agreement was made, and judgment was place upon those deemed "sinful and evil", they were cast down to hell never to see the light of earth once more....
At least that was the plan.
The rules of Heaven soon became to strict for most to enter, so billions were cast out. Sent to be damned for all eternity. Soon The demons were overwhelmed, and they sent an emissary up to heaven to request more room to accomidate the sudden influx of souls. Soon the Emissary returned with God's rejection, he claimed there would be enough space in hell for all time. There wouldn't be enough sinners cast out he claimed.
And boy, was he fucking wrong.
The year was 2019, and hell was packed full. You couldn't walk ten feet without stumbling across aome poor soul hiding out on the street, usually hiding from one of the thousands of demons trying to trim the population. At this time Lucifer had approved mandatory cullings every few decades, but it wasn't enough. Every day thousands of souls poured in to hell, and every day a few hundred were deemed "reformed" and allowed to be reborn on earth. At the rate things were going hell wouldn't beable to contain all the souls of the damned.
Infact the signs were already beginning to show.
Lucifer had begun receiving reports of portals appearing on earth, portals he did not approve of. This was normal acrually, every so often a few demons would grow bored and try to invade earh. Soon the Angels would smite them and send the stragglers back to hell. This time, however, there were dozens of portals popping up , and while there weren't a lot of demons or souls pouring out yet... a few of the portals were directly linked to Tartarus, the Prison of souls so corrupt that even Lucifer didn't want to deal with them. Most were very ancient and powerful beings, long forgotten by time and history, but all were very dangerous. If any one of the souls locked down there escaped.... it would make Armageddon look like the garden of eden.
Lucifer had no options. He needed to send another emissary to plead for an expansion. Thankfully thr portals to Tartarus were too small for any of the massive souls to pass in to, but there was one soul down there who may be able to fit and accomplish this task.
This demon was a special case, he appeared on earth over a hundred years ago with one simple goal: destroy the Kingdom of heaven by any means necessary.
While he never made it in to heaven itself, he made it to the gates where hundreds of angels stood, preparing to smite the foul soul. This legendary demon simply smiled and fought his way though all two hundred angels at the gates. He was known as the angel slayer, a demon who was so powerful he could kill an angel with one punch.
That was untill she arrived. She sent the angel slayer back to hell in one swipe of her sword... or so that's how the legend goes. No one is really sure how much of Atlus's account is accurate, but it is known he did make it to the gates and that She did send him back to hell.
