    Summary

    Seeking shelter from a storm, a blind child descends into a realm of monsters. A chance meeting grants him a companion in the form of a ghostly girl garbed in the colors of flowers. Yet, what seems but a simple adventure becomes much more as memories of dark pasts claw their way to the surface. Lives forsaken, a name unspoken... what does this new future hold in store?

    Summary

    (Told from first person pov) I’m using my name as a place holder, but I’ll try to keep the gender vague.

    I woke up to find I wasn’t in my own world anymore. I had somehow traveled to the world of the hit video game Undertale, but I wasn’t the only one. Sans has a lot of explaining to do. He doesn’t have to explain to much to me though, I’ve read the fanfic, I’ve watched the game. I know more than I’m willing to tell. And most of it is real. How do I sort through the information I’ve gained to figure out why I’m here and what this has to do with Gaster?

     

    Inspired by The landlady, On Top of the Bone Pile, and Six Skeletons One Maid.

    Summary

    Her parents used to go to a campsite all the time when they were kids, but as they grew up, they never found time to go back. Now that they've had a kid and she's grown enough to take care of herself, her parents decided it was time to situate themselves back into the campground, citing their own youthful adventures to their 18-year-old daughter as a reason for their 3-month visit.

    With this in mind, Constance fully expected her summer to be boring, planning accordingly with the things she packed. She did /not/ expect to find herself smitten with the most popular boy at the site, and most certainly never would've guessed that he would eventually return the affection. After a few weeks of flirty passes and a few longing touches, he eventually offers to take her to a place she'll be the first to visit.

    Of course, she goes -- she's young, not stupid.

    Expecting a day of adventure in a nearby town, they instead end up at a cabin in the woods. It was all looking like a perfect romance novel until it took a very horrific turn.

    Will Connie survive these monsters long enough to escape the forest?

    Summary

    The game had been rigged from the start. In the end there was no true win scenario. A world warped into a trap to string them along until they broke and hold them just short of a happy ending. Someone always had to stay behind, and thus everything would reset to zero. There was a chance at a way to move forward however... by looking backwards. So they gambled the highest stakes of all on a simple question. Can a demon defy fate and save them all?

    Summary

    So this is basically going to be what I think happened to each human and what caused the happenings of the game. Some of it is completely head-canon but it's mostly just a crazy theory.

    Summary

    "And they'd never...ruin our plans they way you have. The human souls we'd use to break the barrier...they were all absorbed. All held by monsters you killed. And the souls are all gone now. Any chance of escaping is gone." Flowey cocked an eyebrow at them. "Whoever or whatever you are, you're not them. You're not my best friend."

    "You want to fight?" The flower laughed once more. "Alright. I'll take your soul, and with your determination, I'll reset and free monsterkind myself!"

    As the human drew closer, the flower grew bigger. It's stem grew, and leaves and vines popped out of the ground. This wasn't just some tiny weed. This was a nuisance.

    Summary

    Determination alone is a strong thing. What happens when it just isn't enough? The human faced Sans in battle, only to lose time and time again. No matter the amount of determination in their disposal, no results yielded what they had wanted. They had been chilled to the bone, rattled, absolutely petrified into resetting the timeline to restart in hopes to avoid the conflict- simply by being a pacifist.

    What happens when Sans realizes?
