    Summary

    The voice felt so familiar, tugged at his soul in a strange way that he felt like he should remember. And, at the same time, felt a horrible gnawing urge to respond. But respond to what? He couldn’t remember, or maybe he didn’t want to remember.

    or,

    the past comes back to us in the worst ways.

    Summary

    Grillby didn't like being on guard duty, yet it was neccesary, for the darkness attacks happened almost daily now.

    So imagine his shock when he slayed the most unusual dark dragon he'd seen, and was now stuck raising its children.

    Oh yeah! And he now seems to be sharing a body with these dragon babies' parent!

    Grillby just can't catch a break.

    Summary

    You'd heard about what happened to the monsters- how they'd been captured and taken into custody. They'd been deemed violent and unstable, and there had been a brief public outcry at their treatment, but after that... radio static. That had been two years ago.

    You, a dog person with a passion for rehabilitating the rough ones, had been asked to take in an unintelligent 'dog' monster by the name of Tib. He was shy, touch-averse, and made of bones, but ultimately a good companion for a quiet person like yourself. You were probably imagining the emotions in his eye sockets.

    Summary

    Life had been turned upside down for the past 5 years as the demon hounded her through the multiverse. Throwing them through portal after portal in the hopes that she'd break and obey them. Not only did she resist, she finally broke free of the cycle and found comfort in a home full of skeletons.

    Letting go of the past is hard, but with help the future looks bright.

    First fic, but super excited to be posting! I have a beta reader now, but I still mostly post from mobile. Updates will be sporadic.
    Not sure how to add certain tags, but reader will be female, platonic Papyrus/Reader and the siren sans is underfell not undertale.

    Summary

    Everyone in town, for the most part, knew that a snowstorm was coming. It would last for a few days, and well, today was the day. Papyrus luckily made it home last minute. While Sans didn’t even go to his post and slept in on the couch all morning. To make up for doing nothing, Papyrus puts Sans to work. However, in those few moments where the two went off to do their separate household tasks, Sans randomly went missing. What Papyrus thought would be breifly turns into days of his brother missing. What happened?

    Summary

    There were many things that kept the multiverse running; systems that worked side by side to make sure everything didn't fall apart in an instant. The most well known of these systems were the three main balances.

    Life and Death, Creation and Destruction, Positivity and Negativity — all completely necessary aspects to the universes and the people within them.

    Four Gods and two Guardians maintain this balance, but the multiverse has strange ways of protecting itself as well.
    ~~
    A One-Shot booklet of the Dragon Balance AU, with some additional pictures. I can't promise regular updates or lengthy chapters every time, but I'll do my best.

    Summary

    They had lost.

    Asgore stood, the remaining monsters behind him, and watched as the barrier closed. They were trapped. They had nothing but each other now.

    Monsters all over cried as their loved ones fell down. Parents dusted before their children's eyes. A skeleton child, no more than 12, watched as his older sister fell. She was his last remaining family. He was the last remaining skeleton.

    There was nobody left now. He was all alone.

    (or the story of one WD Gaster)

    Summary

    On Nightmare’s desk sits a slightly burnt file with the name CR-055 on the tab. Singed papers rest inside the file but are still legible. There is a light purple sticky note on the file with Nightmare’s elegant script stuck to the middle.

    ‘The sole remaining survivor of XTale and was very protective of a dead human in armor. Error destroyed the AU due to corrupted codes from someone tampering with them too much.

    I have taken him in as one of my own and call him Cross. We buried his human in the garden under the wild yellow flowers’

    Summary

    The barrier is finally broken, and at last all of monsterkind are free to walk on the surface.
    Again.
    Sans the Skeleton is skeptical. Why bother getting excited for something that's just going to reset? This is not the first time the barrier is broken, and probably not the last. He feels the need to take a break for everyone else's enthusiasm and wanders to the ruins where he encounters a ghost of his past. The result of that meeting is something he has been hiding for a long time and that he's determined to keep hidden.

    Summary

    It's just another late night for Gaster. Not something he's fond of doing, but at least his oldest is old enough to care for his youngest. But when the Royal Scientist finally enters Snowdin, everything is closed, all the lights are off, even the Gyftmas lights were off--as it should, for the ungodly hour Gaster was arriving in--but all the lights in his house were still on. Something wasn't right.

    Summary

    In a half-Swapped Fell-verse, Captain Sans of Her Majesty's Royal Guard unexpectedly finds himself with custody of his younger brother.

    Fair Warning: I had more planned for this story, but I think it's time to admit that I am rather unlikely to come back and finish it. If you choose to continue, I hope you will enjoy what is here and my apologies for the incomplete narrative. Happy reading!

    Summary

    This my old work from Wattpad. I am going to be remaking it and thought I would put the original here as well.

     

    I am a half breed. I am half human and half monster. I believed no one would ever love me like normal people would for each other. That was until I met this one skeleton, who has his own secrets. I can only hope.
