    Summary

    When Frisk finished her story, barrier broken and monsters freed, she knew there was still a loose end, but she never expected everything to come unraveled before her eyes. Determined to save the only family she’s ever known, Frisk must stitch their lives back together after they are ripped apart at the seams and then attempt the impossible to stop it from ever happening again.

    [A story like this has been told before, in many different ways by many different people. Even so, I hope you enjoy it. Please know all major canon timelines and the music of Undertale before reading for the best experience.]

    [An AU of what happens after a specific time kid's True Pacifist ending.]

    Summary

    Frisk didn't expect anyone to help. They didn't expect to grow attached to two friendly brothers, and they certainly didn't expect finding a deeply-coveted secret.

    But, since when were they right about anything?

    Summary

    You are Chief Akuji Rose, a retired military leader and now the chief of police in the notorious city of Ebott. Your reputation as one of the few veterans that survived the disastrous War of 20XX seems to have earned you a great deal of respect and the title of a 'military hero'. You do not appreciate the attention.

    Then a shock shook the ground, and something in the air changed. Everything seemed to come to life. And that's when an entire new race emerged from a huge crack in Mount Ebott; monsters, in all their magic-wielding and powerful glory. Peace is attempted, but it ultimately fails.

    This new arrangement does not sit well with you, and you swear... You will not let it stand.

    Summary

    It's been 5 years since monsters came to the surface. There was a bit of a panic at first, but things have died down. Some people have accepted monsters. A lot of people haven't. Sam and Poppy are part of the exception. Thanks to the wishes of their late parents.
    Sans and Papyrus are enjoying life on the surface, even if there were a few snags in the beginning. One fateful day they run into a pair of human girls who are oddly familar. It doesn't take long for the two brothers to see the sisters as family. They just have to convince Sam and Poppy.

    Summary

    "Tell me the story of The You Now..." Said the child tiredly.

    I found myself swallowing hard, my cheeks flushing as I found two bright, pinprick eyes focused on me. I fidgeted, giving Luke an anxious smile.

    "Haven't you heard that story enough times?" I questioned.

    Luke mumbled a quiet, "no", under his breath. I bit my lip, straightening in my seat at the edge of his bed. I glaced at the skeleton standing in the doorway. He looked non-chalant, but I knew he was curious about my story just based on the flickering of his eyes.

    "Alright..." I murmured, tugging at my sleeve. I let my gaze wander toward the ceiling, letting out a soft sigh.

    "There once was a small, lonely skeleton. . . . ."

    Summary

    ...For everyone who returns to this story and sees this, please be aware that I am going to be remaking this story. I'll leave this one up for reading, but I don't think I like half of the things I did here anymore. So if you're willing to give me a chance to figure it all out, that would be awesome! I'm going to be changing HUGE plot things and characters and stuff, so BE PREPARED FOR THAT!

    This'll just be a collection of random short things, mainly written from prompts, that don't really have enough content to be their own works. They'll probably be completely unrelated, unless I feel like expanding on one a bit, or connecting it to another one.

    Summary

    Life goes on, and the world does with it. Falmercia struggles to keep her past behind her as past enemies stalk her and subtly mess with her.

    Sans just wants to keep his family safe, but Falmercia might be their only hope to keep them that way after things are far too late.

    Can they put their own past behind them and trust Falmercia to help them? Or will they need to find another way. It would be a shame if they did, since Falmercia always seems to have a plan for everything.
