    Summary

    Frisk has reset and tried to make things right more times than he can count, but every attempt has ended in failure. At the end of his rope, he decides to end his own life but the other monsters and a supernatural force intervene and resolve to give the depressed child a reason to live.

    This story comes from my own battle with depression. I finished writing it a long time ago, but I have decided to upload it here because the demons have been attacking aggressively lately.

    Summary

    I meant to die.

    I'm trying to gain my bearings and earn my place in this new world. At first I thought it was just so I would never have to go home, but maybe it's also so I can stay with the bizarre, slovenly mage I have come to care for.

    I've heard of soulmates... Could this be it?

    (Nah basically I have been obsessed with Undertale for far too long and I have far too many head canons, and I need to put them down. Switch the monsters for mages since I don't want to have to deal with ecto-peens, but basically this will be a drawn out romance between Sans and Y/N. I'm serious, they won't meet until a few chapters in and they won't be touching pinkies till we are at least in the double digits of chapters. I have elaborated on the basic world building Toby created and also build on his characters, so there's different sets of rules they play by, and the plot is pretty different from the game. Idk man I'm bad at selling my shit lol. Kinda rough subject matter, read the trigger warnings ok?)

    Summary

    Monsters have been on the surface for a little more than three years now. They have taken over a part of town and very few humans live there. Tensions between humans and monsters are high as monsters fight for their rights and struggle to enter society.

    You, dear reader, are one of the few humans who live in the monster side of town. Your favorite place to grab a bite to eat is Grillby's. The owner is a spitfire of a monster, his violet flames making him rather intimidating. But you managed to get him to accept your presence in his establishment.

    Summary

    A faulty Reset sends a wannabe gamer spiraling into the world of Undertale where she has only her memories of the game, her wits, and a healthy dose of sarcasm to help her survive until the end of the game. Self-Insert as Frisk. No romance except for what’s canon. Plenty of fourth-wall breaks.

    Summary

    Everyone knew and loved Mettaton, he was proud, grandiose, and an inspiration to many. But underneath his glamorous exterior was a miserable, self loathing ghost who was deeply ashamed of his egotistical ways and even more so of his true self.

    Six months have passed since the barrier was broken and Mettaton is living his dream as a star on the surface in a body he loves and the family he's reconnected with. Things seem to be better than they've ever been, until memories he thought he had buried resurface, and his habitual selfishness comes between his relationships.

    Burdened with the guilt of his actions and the secrets he keeps, Mettaton fears he may never grow out of the worst parts of himself as he continues to push his loved ones away. Little does he know that the people around him have demons of their own, and that together they may be able to save them from themselves.

    Summary

    Papyrus is injured while performing his duties as an unofficial royal guard. Ambassador Frisk volunteers to help him apply a healing oil to his damaged bones, but it seems the oil has some unexpected side effects. Will Papyrus be able to resist the ambassador while under the influence of his heat? ..... well, not for very long.

    However, as the two grow closer it becomes apparent that the life of this polyamorous ambassador is very complicated and though she bends over backwards (not always in the fun way) to protect the monsters she has come to care for, secrets from her past have come back to haunt her and threaten to undo all the good she has tried to create. It is good then, that she has the help of such a cool guy on her side... a few cool guys actually.

    Summary

    What if, when the monsters ascended, they came out into our world? We have the game and all of the fanfics and AUs. What if we also have something much older? What if we have an account of when they were forced underground? What if we know them, and have been waiting?

    Well, some of us have at least. Most of humanity has forgotten about about the older texts. Now there is is a top secret organization that is watching the exit and waiting.

    What if you were a part of that organization? What then?
