    Summary

    Red wanted a better life for his six-year-old brother, so he saved his money, scored a new job and hauled the temperamental brat halfway across the city to a new apartment, far away from the cesspit they once called home. Falling in love with his punny next door neighbor wasn’t part of the plan.

    Summary

    You run a little music shop in the town of Ebott - yes, a town in the shadow of that particular Mt. Ebott where monsters first appeared. It has been eight years since monsters first came to the surface, and Ebott Town is as welcoming as ever. How could it not be when all these new monsters want to do is see the sun, see the stars, and play some music?

    It's a day like any other when two skeletal monsters walk into the music shop you and your father maintain - the shorter needs his bass repaired. Cue laughter, puns, shop kitties, and the start to an epic adventure as you meet the gang and help them on a journey to get their little band into a big Battle of the Bands that will end with the winner scoring a great record deal. Frisk needs encouragement, Undyne is enthusiastic, Papyrus kills it on percussion, and Alphys supports behind the scenes as the sound tech.

    Updates bi-weekly, hopefully. I work theater and I'm in college, so gods only know.

    Summary

    When her sister ventures into the most dangerous city on earth to solve a missing-person’s case, Frisk fears that she’s been kidnapped. Dropping everything in her hands to follow her, our protagonist ends up tangled in mafia business and dangerous dealings. As she deals with a determined skeleton, one kidnapping turning into so many more, doubtful monsters, a man who speaks lies as his first language, and the threat of mages returning to bring the world to chaos, it's pretty hard to keep her cool.

    Sans is the anchor in her storm, he’s everything she’s ever wanted; he's tall, handsome, confident, mysterious and kind. And although there's the small issue of him being part of a mafia, and to top it off, heir to the strongest mob in the world, Frisk can't help but feel like he's exactly what she needs to get away from the life she desperately hates. She wants to escape the claws of her foster family.

    Set in modern times.

    Summary

    Alienstock. A stupid joke about storming Area 51 in September in an attempt to "see them aliens."

    That's all it was supposed to be, anyway.

    A stupid joke.

    So when you find yourself inside of the infamous military base along some some hundered-thousand others, you're more than a little flabbergasted by the turn of events that landed you there.

    And the ones that led to you fleeing with some weird jerk of an alien in tow.

    Summary

    If the fair folk do you any favors, don’t say thank you. To be indebted to a fae is a dangerous thing indeed. But if you want to show gratitude to a fae, give them a small trinket -- they have no use for gold or the kind of power politics will offer them. To have a fae indebted to you, though, is also a dangerous thing.

    I have lots of ideas, but no place to put them. Receive my terrible ideas.

    Summary

    Consequences. Had you known there would be consequences, you wouldn't have done it. How were you supposed to know there would be consequences? You were just an oblivious god in a world full of oblivious gods, after all. You hadn't meant to ruin Undertale, ruin all the lives of your friends. Yet there you sat in front of your computer for countless hours, trying - and failing - to fix your mistake.

    It was a little game called OneShot that made you realize just what you were capable of, and now Niko might just be the only shot you have at saving Undertale. You've spent years planning and coding, leading up to this moment. And now, it's finally time.

    ~Updates (hopefully) every other Wednesday~

    This work is supplementary and is not needed to get the full story of AberrantTale, all relevant information will be in the main work.

    The magic system is loosely based on the system Sophtopus has for GQ, but it is heavily modified and also contains D&D elements.

    Summary

    Why is it so cold when you're in the sun? Why does food not satisfy? What douses your good days in spirals of thoughts that you don't control? Why do you feel so hopeless when you're doing fine?
    The answer may surprise you.

    Soulmates? On my PC? It's more likely than you think!
    In all honesty, I haven't the foggiest on what I'm doing, but I hope it's good.
