    Summary

    The child paused mid step, their non-Existent eyes wide with a mix of both wonder and fear as they looked at the mess before them.

    It was hard to decipher who or what could have done this, or even what ‘this’ was. After all, the mass assortment of AU’s that had caught their attention clearly wasn’t the doing of either Ink or Error, or any other outcode for that matter.

    ‘So who was responsible for this?’ They pondered, grey fingers brushing idley over the intricate designs that encrusted the cover of the book.

    Fortunately, Core had a feeling they wouldn’t have to wait long to find out.

     
    ———————————————————Or———————————————————

     

    A storyshift Chara wakes up in an Undertale Sans’s timeline with no recollection as to how she got there, and as the two race against the clock to get her back home, the rest of the multiverse Outcodes are left to discover just how deep this rabbit hole goes.

    Summary

    Noelle thought her "Dream" was bad.

    That was before she woke up to a nightmare.

    With Berdly gone; a new dark world that Kris wants to drag her in; the entirety of Hometown pacified; Susie, Officer Undyne, Sans's Brother, and Ms. Toriel lost to the void, and only a few days to save her childhood best friend from whatever force was making them do all of these horrible things, it's safe to say that Noelle has her hands full.

    With only one of her new neighbors, Ralsei, and a few familiar Darkners to help her out, can Noelle save the people most important to her before it's too late?

    Or will she submit to the terrifying power that's holding them all hostage?

    Summary

    Nowadays finding dead bodies at the drop are a normal thing lately for Toriel. It's almost impossible to find the humans alive when they fall.

    So how exactly is she supposed to react, when she finds a human woman alive after such a drop?

    Granted she was bleeding out near grotesque wounds, and her soul was pulsating dimly and slow, but she was still alive. How will she react? What will she do? What will happen when she meets the other monsters?.......What would Sans do when he finds that it's not Frisk who fell this time?

    All I can say for sure........is that Sans is fucked.
