    Summary

    You wake up from a coma with a switched soul and no idea who you are.

    Your simple plan is to have a drink and then find the tallest cliff you can.

    Grillby interrupts that plan, adopts you, and takes you across the country.

    Now you're meeting skeletons that are saying you're an anomaly.

    One of them makes the mistake of saying you shouldn't be there at all.

    Summary

    “Come closer, weary traveler, for I will tell you a story...”

     

    For centuries, you’ve cared for the lost and forgotten of your country. Only when the last of your “children” leave do you attempt to take a well-deserved rest. Emphasis on attempt.

    It’s the arrival of three young skeleton brothers (and a flame elemental?) that heralds the coming of a whole plethora of trouble.

    Especially her - the beginning of the end.

    And that is where our story will begin.

    Summary

    You had been raised to be a hero, to defend humanity against monsters if they should ever show, but when they do-there's no need for heroes and no need for you.

    Years later you get summoned by your old boss to help with a problem that threatens the peace between monster and human kind. Someone you knew is tearing apart the fabric of reality and bringing boss monsters from alternative worlds to yours. You need to team up with the monster mascot and his boss brother plus their softer, alternative versions to track down the new arrivals and...make nice. But is that all?

    Months (and a few skeleton brothers) later you've tasted the delights of domesticity and are willing to believe it might be for you. Maybe the world isn't as in need of saving as you were once led to believe. Maybe, this time around you can be happy.

    Summary

    For Monsterkind, the Surface represented freedom.
    For Frisk, it's a return to some uncomfortable realities.
    It all began with a simple wish. When that wish faded, Frisk tried to move on.
    Except, 'moving on' was not so simple. Emerging from the Underground had put them in a worldwide spotlight.
    From an unknown child, they had become an icon of great value.

     

    'The Golden Quiche'

    What to expect from this story:

    -Mystery Drama
    -Anime
    -Extensive Surface Worldbuilding
    -Expanded History and Backstory
    -Magic System
    -More Magic
    -Both new and old people.
    -Feels.
    -Gambits.

    What to not expect from this story:

    -Toby Canon.
    -Commonly agreed headcanons (about a certain scientist in particular)

    Summary

    There is only so much pressure one can take before they crack. Sans hit his limit long before Frisk came crashing into his life like a brick, and everything started falling to pieces. He just didn’t know it yet.

    Summary

    It was easy to convince the King to grant him access to the five Human SOULs, promising through his work an alternate method to breaking the barrier. Who was he to deny him? The Royal Scientist had already made miracles happen, so why not another?

    The hard part, however, was to not get attached.

    And it was much, much, easier said than done.


    You wake up from nonexistence, finding yourself in a creepy, unpleasantly smelling laboratory with seemingly no way out. You’re lost, nonplussed and have no idea how and why you came to be. But perhaps that skeleton man from earlier can help you find some answers...

    Well, only if he decides to stop being so infuriatingly mysterious all the time.

    Summary

    A gang of outlaws moves in on the sleepy little town of Deadwood. Unfortunately for them, there's a pair of outlaws already in town - and they like the streets better when they're quiet.

    Summary

    “...do not be rash...the only reason I am telling you this is because I need you to pay your tab.”

    Sweat formed on Sans’ brow. “What are you getting at, Grillby?”

    Grillby silently turned to the register on the far right of the bar and punched some buttons. After a moment, a long piece of paper spit out of a metal slot. It rolled onto the wooden floor. Grillby snatched it up, miraculously not burning the paper, and handed it to Sans. The skeleton’s eyelights browsed the paper, then quickly extinguished. His hands trembled. “This...can’t be right, Grillbz,” he mumbled, voice shaky. The bartender took the paper and distingrated it.

    “...I will forgive your tab just like this paper...if you take in (Y/n).”

    ***

    (Y/n) gets taken into the care of six skeletons! The only thing is, she has skelephobia...

    Will her mysterious past and daunting fear get in her way of love?

    Summary

    Your name is unimportant. Your job is nonexistent, really. And your (ex)roommate just kicked you out in the middle of a surprisingly cold November night. But whatever. You don't care. You'll be fine.

    Keep telling yourself that as you freeze to death, idiot.

    But you'll be fine, for one reason! Two, actually. Two people - monsters really - who just so happen to have the same names as some fonts you know of? You stay with them instead, just to get back on your feet, and a single question rises to your mind.

    What the hell is keeping you here?
