Summary
Hunter needed to leave, everything hurt and he was bleeding everywhere! He felt slightly angry and scared. He shoulsnt feel this way. Uncle punished him all the time why was this different? Maybe it was the yelling, maybe it is how deep the cut is maybe its because he learned things he shouldnt of. He does not know. But what he does know is that he’s running and now he isn’t in the castle. He’s in the woods now and he trips. He looks back and notices the door like structure he tripped on. He pulled it out and it looked like the portal his uncle was making. Just slightly different. He decides to see where it leads.

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

Summary
First, I am just going to say, this is not a shot at anyone's religion in any way. If the religious references make you uncomfortable, you don't have to read this.
Since the second season is still however long away, I'm working out my obsession with a fic. This takes place after the first season. Abaddon goes to find bones, and ends up running back to the hotel with the ghost of a rather angry priest right on his trail. I am currently obsessed with the Nathan and the priest ship, so yeah, they gonna be gay, and they gonna crack...eventually. We gotta do some sad shit first.

Summary
Multi-chapter (hopefully!) fic about the events before Haunted Hotel starts.

Summary
Scraping by on pennies, the Undervale finds possible hope in one unusual guest who’s looking to crash there for a while, in cash.
Surely there’s nothing wrong with her.
Abaddon is only interested in the hellbeast she rode in on, after all, not how Nathan fumbles around her.

After a failed exorcism, the priest dies and returns as a tormented ghost. His son, Isaiah, survives a fall from a cliff, but his seven-year-old body is possessed by the demon Abaddon. To prevent the boy from dying, Abaddon binds their souls together with an immortal bond: the wound never heals, the body cannot grow or die, and Isaiah's spirit remains trapped like an echo in his own mind.

Summary
It was a day much like any other, if not better than usual. He’d woken to a bird upon his windowsill, peacefully preening, and it even seemed to chirp in response to his morning prayer. His shoes buckled easily, and he didn’t stumble on the raised floorboard in the hall. Breakfast went well, too, as father even patted his shoulder ever so briefly, even if he scrubbed it against his pant leg immediately after. Any affection was rare from his father, so he must have been in a very generous mood indeed!
~
Isaac was a good boy until he wasn't. Abaddon learns to live, love, and suffer as a human. Family isn't all that hard to come by, even if it takes so long. Wounds need not ache forever.
