    Summary

    After the death of the World Eater, Mundus was shaken by a new Dragon Break. Many universes were connected by passageways to Nirn - and their inhabitants are also not averse to solving their problems with the help of Dovahkiin and his heaven-illuminating VALOR. Especially when they lack their own DETERMINATION...

    Summary

    I finished Undertale not that long ago, and I wanted to look for a good fic that was essentially an epilogue to the true pacifist ending. I couldn't find anything that wasn't smut or reader x sans. So I took it upon my mostly inexperienced writer self to write it. Now it won't be super serious. It'll probably mostly just be the characters being goofy and getting used to the human world. But with that out of the way, welcome to... After the Barrier Falls.

    Summary

    “Legend has it that long, long ago, two races ruled over the earth…”

    Frisk and his colleagues were sent on a mission to investigate Mount Ebott after another group of children were reported missing. Despite the rumours, none of them believed that there existed a different, more advanced race residing in the mountains. But once they actually go beneath the surface, missing children weren't the only thing they found that day. And it was completely different from what they have had in mind.

    With what they have uncovered, Frisk found himself starting to question the liability of humans - of the people whom he once trusted in…

    Other OCs, story and illustrations belongs to me.

    Nov 2024 Update: After further discussion with the requester, we have decided to put the story on-hold for an undetermined period, as I have proposed the idea of turning this into a game project instead. Thank you for understanding, and if the game project went smoothly, we may meet again in the future. For now, farewell, readers, and thank you for reading.

    Summary

    Long ago, there we’re two races who ruled the Earth.

    Humans and Monsters.

    One way war broke out between the two races.

    In the end the Humans won and sealed the Monsters Deep Underground with a magic spell.

    That is how the Humans and Monsters relations, came to an end.

    But what if I told you, that is not how history was truly written?

    History is often told by the victors, but in that war, there we’re no victors nor losers.

    (Or the humans survived and will have to save and protect the world above as their Guardians.)

    Summary

    In an AU where Asriel had managed to talk Chara out of their plan, it seems as if it was never their destiny to continue growing up together, as monster kind wants the human dead.

    Summary

    Our home died 5 years ago alongside Mom. I still have my little sister and my Dad, but her death destroyed everything for us. Everything got harder, everything was falling apart piece by piece. I tried picking things up and putting them back where they should be, I started working to help afford food, and I stepped up to protect Frisk from everything I could. Nothing I did was enough. Dad drank away all the money I would bring in, the house could never stay clean, and Frisk would get hurt when I was away. Frisk began to stay out late and avoided coming home because of it. After work I'd spend hours looking for her, fearing that one day she would just disappear like all the other kids. Eventually, she did.

    Summary

    It had been 4 years since his father's, both of his father's, talk. instead of seeking revenge, he let these emotions drift past him, into nothing more than nightmares and memories. He ruled Pribyslavitz fairly and justly, as its Bailiff, for four years, building up a large stockpile of wealth from the exemption of taxes, but not all is well, the constant rumors of that ancient mountain to the town's back, Mt. Ebott, swirl across the tavern and quiet places of the province. It's cursed, they say, but full of gold and silver. Henry never carried for these rumors, and apart from sending the occasional locater to find any surface deposits, he didn't bother with the mountain. That is, until today. And today, he would find himself in an entirely different world—a world, of Demons.

    Summary

    Of chance encounters and surprised faces, as one story ends another begins!

    The world is about to get a lot more interesting for everyone, both the participants and its audience.

    whether they like it or not.

    --------

    I always felt like there was a story even after the story of Undertale ended, so I decided to make one.

    This is not to be treated seriously and is an attempt at a light-hearted ish story.

    Feedback is appreciated as well as the occasional suggestion.

    Summary

    Monsters are finally free from the Underground, and Frisk has returned to the surface with all their friends. The battles are over and the heroic journey is finished... But happy endings don't just appear by magic. They take time and effort (alright, and maybe a little magic), and you take them one day at a time. This is a lesson that Frisk, Conor, and everyone else still have to learn for themselves.

    Summary

    You're tired. So tired, in fact, that you can't bear to stay in your own universe for any longer than strictly neccessary to build a machine to get you out of there.

    Is it because you are suffering an apocalypse?
    Has your world ended in destruction and death?
    Was there something directly affecting you that brought you to this conclusion?

    No. You're just some human with depression, but would literally rather experience the potential horrors of space-time travel than go out by your own hand. That's it.

    Even if it means leaving the one person that cared about you there behind. Hopefully, it's worth it.

    Summary

    He wished to find the children that fell down Mount Ebott. To return them back to their homes, where they ultimately belonged. Seeing that his own home life wasn't the best, he could only think of the worst to come to a family that wasn't broken like his. And his heart ached with justice for them. So, he fell. Ending up in a strange world he already resented. The king, ASGORE, he was told, was the reason for all of the children's disappearances. And it made his blood boil just hearing that. These monsters were responsible for the children's deaths. And they were going to atone for it. For all of it. He made monster-kind pay, wiping out half of their population just in a week. Even though it felt way more longer then just one. It was the end. He was near freedom. (Continued Genocide)

    This is your story. A not so nice one, mind you, but you're pretty used to that by now, huh? Yet this one has it all: the violence, the thrill of a thief's life, betrayal, a horrible man in a black top hat with an even more horrible fate in store for you, and a terrible truth you wish you never uncovered!

    Summary

    A year after a successful neutral route. Nobody had believed Frisk at first about monsters trapped in the underground. However, a cruel reality sets in much more corrupt than ever imaginable when the Barrier is destroyed. Monsters were liberated only for a brief period once the humans discovered just how broken and savage they were after years of starvation, forced into confinement and brutalized following their release.

    You'd been working as a therapist in a rural town when one day, you'd been offered a brilliant job opportunity far out East; an organization attempting to rehabilitate the monsters that had come to the surface are trying to recruit willing human mental health professionals. You, reluctant, knowing how dangerous this job could prove to be, refuse to take the opportunity... until a heaping amount of cash is proposed. Who's to deny that in this economy?

    Surely nothing bad could happen.

    Summary

    How far would you go for something you love? Would you sacrifice yourself? Would you sacrifice others? What will you do, when pushed to your worst?

    I’m sorry.

     

    Orion was living a pretty happy life. A perfect example of an escape artist. She has her own form of entertainment and lives her daily life without a care in the world.
    She was free from any sort of attachment.
    However, a new discovery forces her into a mess she wasn’t aware of. A demonic flower without a soul? Sounds cool at first but leads to a problem she can’t run away from.
