Summary
Abaddon isn’t a demon, he’s a child raised in a cult and told his whole life that someday he would reach his true potential and his real form. He was rescued from the cult, but he’s been hospitalized ever since with severe PTSD and religious psychosis. No one has been able to get through to him yet, but Katherine has just been assigned to him as his new trauma therapist, and there might be hope for him after all.
Inspired by Forgan’s mental hospital AU and written with permission.

Summary
PLEASE READ.
I cant figure out this app SO im adding most of the tags in the summary as I go along.
Ritual gone wrong, a bit of angst and bonding between everyone, might be slightly ooc every once in a while, although I try to keep it as close to canon as possible.
To sum it up in the short, Abaddon and Esther fail a ritual, or so they think. Abaddon makes a crucial mistake and eventually, it'll make him grow back a few of his old demonic features.
Not without a lot of hurt, Angst and comfort along the way of course. -

Summary
The catholic priest Ben had called upon to exorcise the Assyrian demons finally shows up, albeit with his heart set on exorcising the wrong demon. When the Freelings fight to save their favorite hell prince, Abaddon is put in a position where mortality might be his only way to stick around in a life he’s now grown quite comfortable with.
Mortality comes with its own trials, tribulations, and experiences though—most notably, sharing not only body but mind with the vessel.
Though the shift is jarring and initially unwelcome, the change in perspective helps Abaddon see the Freeling’s through a different, more earthly lens.
The hardest part of being mortal, however, might just end up being what *hasn’t* changed. -
Tags
Summary
A powerful ritual gone wrong violently ruins Abaddon in the most peculiar way. Something that would barely affect a common person seems to be seriously harming the Freeling’s heirloom demon boy.
Or
Acts of kindness on Abaddon’s part have never gone so wrong.

Summary
"Is this not how you would prefer it?"
Katherine sighed, "I needed space from you, but that doesn't mean you hide in the vents with nothing for five days!"
"Why not?"
"Because you're punishing yourself, it wasn't really your fault," Katherine observed Abaddon in a way that made him fidget
"I don't see how that's a problem?"
or,
Abaddon has a weird idea of how and when to apologize for things, the Freelings are worried.Bookmarked by aliencritters

The countless times Abbadon has looped the history of this earth, and the countless times he has watched the Freelings perish despite his attempts has left him drained, both physically and mentally.

OR, Abbadon is tired from the loops and seeds sleep and rest but doesn't want to admit it and the Freelings don't know what's wrong.

Summary
Abaddon’s eyes glisten. “You don’t understand,” he pleads, his voice small and shaking. “Please—I’ll behave! I’m sorry! I’ll be—I’ll be good!”
Katherine’s hand trembles as she slips the crucifix over his head, pushing down the guilt she feels. “It’ll only be for a few hours,” she says quietly. “I really didn’t want it to be this way.”
The moment the beads touch his skin, Abaddon cries out to her , a sound that doesn’t belong to a child at all. Katherine forces herself to turn away, heart hammering as she steps out of the attic. She has to remind herself that that isn’t a child, but a spawn of hell in a child’s body.
The door slams shut behind her.
OR
Katherine accidentally curses Abaddon with a crucifix, causing him to grow extremely sick. She’s left with no choice but to do everything she can to save him before it’s too late

We were never given much insight into Nathan and Abbadon’s time together before Nathan took his life and Kathrine took over the hotel.
So here’s a few Oneshots about Nathan pretty much adopting this little demon boy
Also yes I know I spelled Abaddon’s name wrong. I’m too lazy to go back and fix it
