    Summary

    You're a normal person... or what passes for normal. You have a part-time job and a boyfriend. You love video games and you're a serious Undertale fan. You aren't a social butterfly like your job makes you be just for the sake of it. You'd rather just stay at home. So you do, on your days off anyway. Then something happens you don't expect and suddenly you're wondering if you're really the person you thought you always were because something isn't right with your soul and that's just the start of your new-found problems.

    Summary

    (New Summary)

    Undertale? Of course, you’ve heard of it. Who hasn’t heard of that popular video game? You’ve read more fanfics for that game than you can count. You never once considered that it was more than just a game, though. It’s not until you suddenly wake up in the world of Undertale that you realize that the characters are actually real. Amazing as this is, you can’t help but be concerned about how you got there. One minute you're walking to class, and the next you're waking up in the snow. And, if appearing in Undertale wasn’t already a big enough shock, you keep AU jumping and ending up in different Undertale-based worlds! While you have no problem with meeting the different versions of everybody’s favorite skeletons, you quickly realize something weird is going on in each world you visit. Something that’s causing a lot of trouble and damage. Looks like you won’t be able to go home until you figure this mess out. Well, at least you get to befriend some cute skeletons along the way.

    Wait a minute! What the hell is wrong with your soul?!!

    Summary

    You gently pushed the door and here you were, outside of the ruins. The first thing to hit you was the cold, then the realization that you just left the only safe place available to you. The second thing to hit you was that wow, maybe it would be warmer if you weren't wearing just some t-shirt and old jeans. The third thing and the last, was that now you were aware of holes in your sneakers. It felt like it was going to be a great day.

    Summary

    You are Sentinel, a human involved with the monster mob for the last year of your life. It's taken that time to gain the trust of Boss, Undyne, Grillby, and the rest of the monsters, the only human included in their inner circle. But this only makes you a bigger target to the rival clans and mobs. Someone is working to force the monsters back to the Underground, the prison of their once and former King, and will stop at nothing to do it.

    You'd give your very Soul to keep it from happening.

    Summary

    Word has hit the world, Monsters have reached the surface from Mt. Ebbot! But after that exciting news story and the follow ups, what happens? Absolutely nothing. Nothing changes for you, a college student, studying from the community college in the backwoods of the small town you grew up in. So, as the stories quiet down and the years go by, you forget there even is another race living among you. That is, until you meet some during a trip to a big time nerd convention.

    Based on if Monsters had a physical manifestation of their soul (dæmon/soul searcher/searcher) from The Golden Compass!
    Officially named Compasstale and made by yours truly!

    Summary

    Currently sitting on your 8th floor apartment balcony, you were crying into a glass of wine. You slowly lifted the glass to your lips, and gracefully chugged the remainder of the wine. You are nothing if not a classy drunk.
    --------
    hey!!! this has a few dark themes but is mostly centered around recovery and has a bunch of fluff! i appreciate constructive criticism ;P
    I'm a sucker for the "opposites attract" trope, so you're a kind-hearted green souled human girl with an apartment in the city. Sans spots you and develops a crush. Shenanigans ensue.

    Summary

    You're a mostly shy and ill-mannered girl endlessly blaming the world for something you yourself aren't quite sure of. You hate that you're stuck being unhappy while the rest of society- monsters and humans alike- stroll along with their happy lives, unaware of your miserable state of dependancy. You envy others for their tenacity to survive the world when you can't...

    Everything changes when you meet a tall skeleton monster with artisan spaghetti dreams, an anime-loving fish monster, and her much shorter lizard-monster girlfriend obsessed with Mew Mew Kissy Cutie. Can the three find a way to change your stone cold heart and bring you out of your monster-bigoted mindset? Or will you fall victim to living the same lonely life you've lived since the beginning?

    On top of that, will a pun-loving skeleton still wary of this reality vanishing help you out with his friends? Or will he be the one to push you over the edge into misfortune?

    WARNING: Reader is not a nice person in the beginning, and that is intentional. You will cringe. You will scream at the computer. Some characters may seem out of character, but that's intentional as well.

    REALLY Slow burn! Hate-love!

    Summary

    "We need to be strong. No one will mess with us if we're strong. I'm sorry but... I don't think there's any other way."

    As children, Sans and Papyrus made a promise to each other. A promise to protect each other, to stop each other from getting hurt. They never said it aloud, they never talked about it but it was also never far from their minds. Sometimes they could keep the promise, sometimes they couldn’t. They would try anyway.
    At times, things seemed almost okay...

    Then you came along.

    Summary

    The paradox of freewill states that if an omnipotent being could exist, one who knew the past present and future, that freewill could not. The existence of an omnipotent all knowing being would determine that all choices and decisions were predestined and no matter how autonomous you may feel you are you truly are a puppet to fate.

    After the monsters were freed from the underground you had been plagued with strange dreams, light headedness, nosebleeds that bled black goo, a voice you can't understand reverberating through your head. You have knowledge of things you shouldn't know. Haunting probably wasn't the right word for it. It felt more like only half of your body was being possessed by an intruder.
    The paradox of freewill states that if an omnipotent being could exist, one that knew the past present and future, that freewill could not.
    W.D. Gaster was the omnipotent being in this equation.
    And you weren't satisfied being a puppet anymore.
