Summary
La realidad no es más que un tejido fino sobre un abismo de estática, y alguien —o algo— ha comenzado a tirar de los hilos.
Tras la aparición de una fractura en el tejido del multiverso, lo que comenzó como una misión de rutina se ha transformado en un descenso a la locura. Mientras los guardianes del orden y el caos intentan mantener una fachada de normalidad, los cimientos de la existencia comienzan a resquebrajarse. Fragmentos de recuerdos, lealtades fracturadas y una conexión prohibida amenazan con borrar la línea que separa la identidad de la aniquilación.
Dream y Nightmare custodian un pacto de silencio que podría salvar —o condenar— a todo lo que existe. Pero en el silencio, algo los observa, y la sincronía que comparten empieza a hacerse notar más allá de su voluntad.
Todo vínculo tiene un precio. Y en un multiverso donde la verdad es el enemigo, la ignorancia es el único refugio que queda.

Anyone can make them as long as they give credit.
Because I would love to read them if people made them.This will get updated whenever I think of a cool fic idea

Summary
With discrimination on monsters on the rise, the need for medical rises with it. Who better than someone who has a bunch of secrets and who can’t help but to be kind to even the smallest of kids - you.
The schedule for this fan fic is going to try to be a chapter every two weeks but i am a tired college student so who knows how ill keep to that lol. I hope you all enjoy this newest passion piece of mine this story has gotten me through some rough rimes recently.
update: ive gotten this question a bit but this is my own take on the underfell au. its not the canon underfell au.

Summary
In the small town of Ebott's Wake, Oregon, there are many colorful characters. Perhaps none so colorful as Old Man Schmitt, at least until the Barrier was broken and the monsters showed up. In many timelines, Schmitt created a device that he thought would allow him to transcend mortality and humanity, becoming a being of limitless potential. And in one timeline, it worked.
Sort of.

Summary
At the last moment, Asriel couldn't go through with Chara's plan to save the underground. They were already very ill and near the brink of death, but with their family's help, they managed to pull through. The attempt left permanent damage.
Now, years later, the Angel of the Underground faces mounting pressure to fulfill the prophecy and their worsening health. Luckily, the Royal Advisor, Carol Holiday, has a good-for-nothing daughter that has nothing better to do. And so, Dess is assigned to aid them in whatever ways possible as their Lady in Waiting.

Summary
You, a human, find yourself in the familiar horror of the Void, after your SOUL is yet again rejected from an AU- seemingly never able to find its place in the multiverse. Yikes. Maybe a certain group of skeletons will take interest in your situation..? Loosely based on the song Ghosting by Mother Mother. (This story is written in 3rd person, so no mentions of y/n or the reader. The human is literally just referred to as 'human.') WIP fic! I pretty much update daily :)

Summary
The only question that hung on Asriel’s mind was a rather explicit one. It was one formed from the intensity of life’s emotions, he’d been at highs, he’d been at lows.
And yet he’d never been this low before.
And so he asks, “what the hell do I do now?”
—-
Or Asriel returns after chapter 5’s weird route to attend the funeral of Kris, Noelle and his father. He and Susie set off into the deepest darkness to save the day. And along the way confront old demons, new enemies, and things that should stay in the dark. -

Summary
In the beginning, there was a collective of voices. The collective needed a muse, for they could not create full universes. The only things they could make were unwhole sketches, and from one of those sketches, came their much needed muse, who was named Ink.
At first, Ink obeyed their needs. Created what they wanted him to. But when Ink wants to create on his own, the collective, "The Creators", needed another being, as their viewing of Ink's creations were deemed useless for their multiverse.
That other being is a glitch that fell into the anti-void, Error.
But, even though this issue is easy to fix, stubbornness leads to otherwise.
note from august 28, 2025: Fic name changed to Cause and Effect. Former name is FGOD AU: An Alternate Story.Series
