    Summary

    A found family, a cold case, and a child's custody.

    A shotgun wedding, a detention center, and the skeleton you married becoming your lawyer.

    You've checkmarked all six as things you would've never expected to be involved with, and with how it goes, you're certain you'll have a seventh one to add to your list.

    It's perplexing to remember it all began with you missing your stop after falling asleep during your train ride home.

    And as more days pass, you can't decide whether that's a good thing or not.

    Summary

    after two years in the ruins, you have finally decided to leave it behind and explore the rest of underground.
    you're not leaving forever, obviously, you were going to return before dinner.
    you're bound to meet some interesting people, make friend and maybe something more.

    A/N:
    this is my original au called fallen soul, you can follow the canon timeline on tumblr under @fallensoul_avtfol
    the fic starts from the 4th or5th arc of the story, centuries after gaster's fall.
    this au is inspired by underfell and timetale, but honestly isn't that much like them anymore.
    it's mostly a au about emotions, grief and letting go and healing.
    there will be a lot of angst and a lot of feels.

    Summary

    Golden light filters through the stained glass windows along the left wall. You finally made it: the end of your journey. One final challenge stands before you.

    A figure standing in the shadow of a pillar shifts slightly at your arrival. It's not the monster you are used to seeing in this room, but... you were expecting him. You killed his brother, after all.

    Even though he stands in the darkness, you can still see his bony smile.

    "HELLO, HUMAN."

    Summary

    Not only does a human fall into the Underground, the last human they need - but this human can see things. Things they can't begin to understand, things that took Sans years of hard, regrettable work to become aware of.

    On the other hand, they're flirting with him.

    Sans doesn't like this one bit.

    Summary

    You had been an alpha stage design of the fallen human, but you were discarded; existing between the main game and the void below. Sometimes, brightly shining lights would fall here and crash into the void. A blue existence has been flickering in and out of this place and you muster enough Determination to stop them from Falling Down.

    You don't know what saving them will do; but no sentient thing deserves to crash into the void below...
