Another AU that's up for adoption, because I like the idea, but don't have the brainpower to do anything but a couple of doodles for it.
Basically: Exorcists were members of Lillith's rebellion against heaven, but with their memories wiped.
Lilith WAS indeed staging an uprising against Heaven, with an army of demon's under her.
To prevent them from attacking a deal was made with Adam, which Lucifer agreed to to, to Allow Lillith and all her followers into heaven.
Lillith agreed, but some of her followers were secretly planning to take down heaven from the inside.
However, heaven had anticipated that, and once they arrived in heaven, all of Lilith's followers had their memories wiped, and became the exorsists.
Not being winners, their appearances changed once in heaven. Sera was surprised when they gained halos, but the halos were black, signalling that they were still damned by their sins.
Everyone's memories of the exorcist's past lives also are affected. People do not remember them, and are unable to recognise them when meeting them again. However, day ja vu and confusion is very common for people who interact with them and used to know them. When trying to think of of past, others remember things they did, but not the person they did it with, or what happened to them.
Technically the angels hands are clean, since it would be demon's killing demon's, using power gifted by the Angel's. Meaning that Sera and heaven don't technically have blood on their holy hands
Lucifer was tricked by the wording of the deal. Being naive, and already upset that Lillith was leaving him, he didn't think of the repercussions. The contract stated that he wasn't to intervene against Heaven doing whatever they chose to stop another rebellion from happening
Heaven's method to prevent another uprising from happening involved killing Sinners every year so they couldn't make another united front against them.
Since he'd already made the deal, Lucifer was powerless to stop it, and too ashamed to tell Charlie what really happened that day. That he was tricked, and her mother who she admired so much, had left them for a chance at a better life in heaven.
Which is part of why he spirals into depression. Guilt, hurt, and being ashamed. Then after some time, he felt too awkward, and convinced himself that Charlie must hate him for leaving her to deal with her mother's disappearance alone.
Vaggie was an Overlord known for helping sinners ruthlessly take over territory in a very war-like manner. She often was involved with collaborations and deals with Camillia Carmine.
Lute was a hellborn from wrath, who ran a league of assassins. She idealized Lilith, and the way she controlled and inspired so many sinners into action, so jumped at the chance to work with her and help mobilise an army against Heaven. However, she was often too ruthless and violent for Liliths tastes.
Alastor was a sinner who took the opportunity to side with Lillith shortly after his death, to get power as quickly as possible. Possibly even making a soul contract with her.
He recruited powerful demon's into Lilliths army, by persuasion, force, or deals made. Some were killed, by him or by Lillith, but a lot were recruited for her army.
Niffty was a sinner who worked at Lillith's Palace before the Queen disappeared, who Alastor adopted into the group of sinners he had collected. He doesn't own her soul, they just have a mutually beneficial agreement between them.
Husk was supposed to be recruited for Lilith's army, but Alastor instead decided to keep him as a thrall instead, since he was very useful, being able to read people so accurately.
