    Summary

    You're from the Horrortale universe.

    A universe where everyone has suffered-including your favourite skeleton brothers.

    You were merely 15 when you fell to the underground-a lot has changed in the four years you've been there. Somehow, along the way, you'd convinced the butcher himself to not slice you into mince meat, and even moved in with them at some point. Nowadays, you spend your time struggling to survive WITH the skeletons, rather than against them (thank god).
    Though things are about to take a drastic turn. You thought one pair of skeletons was strange enough- try 8 for size.

    Summary

    You and your best friend have been through it all,
    literally.

    Ever since you gained the skill to remember things, they’ve been there. You two may have had what others called flaws. You, with a perpetually tired body and them, with ears that couldn’t hear but you’d be damned if you two weren’t there for one another. You two are outcasts and after your grand escape from the local town mob, you plan to venture deep into the mountain, that is if you two survive the bottomless pit fall. Which isn’t too likely.

    Funny how life surprises you.

    Now you two have to venture through a world much too harsh for your soft loving heart.

    Summary

    Red wanted a better life for his six-year-old brother, so he saved his money, scored a new job and hauled the temperamental brat halfway across the city to a new apartment, far away from the cesspit they once called home. Falling in love with his punny next door neighbor wasn’t part of the plan.

    Summary

    When Papyrus refuses to trade his brother’s life for comfort and safety, he becomes a fugitive of the Underground with a high bounty on his head. It wouldn’t be so bad were it not for his brother deciding to Fall Down and leave Papyrus all alone.

    Being forced to hide and defend himself and his Fallen Down brother, Papyrus does the only thing he can think of. He forces Sans busted machine to work.

    ----

    Sans knows he’ll never be a part of the guard. He knows Papy and Alphys still see him as a child, but he’ll bare it with a smile if it means his brother is happy and relaxed. Maybe he can talk Alphys into convincing Papy that he’ll be fine, though. For now, however, he’ll settle for mediocre training with Alphys. He can always practice on his own in the clearing behind his house. Just like every other day…

    It’s the same thing, day in and day out. Over and over and over again.

    Until it isn’t.

    It’s been almost a year since the monsters reached the surface, and although you are dying to meet one in person, they all have made their home near the base of Mt.

That is until you go with your brother to his new place and get the chance to meet his new roommates.

    Let’s just say he has more than a few skeletons he’s hiding in the closet of his new place…

    Summary

    Drabbles* set in the "Ebott is a Multiverse" series.
    Some are just theoretical. Some are very much Canon to the series.

    Look for the [Canon] label for that stuff.

    *no guarantee that any chapter will actually be a drabble

    Summary

    With no memory of anything else besides your childhood companion, Oliver; You are forced to live in the woods, thankfully in a very large building that serves as your new home.

    It was peaceful; You were making due with what you had. Some slip-ups here and there, but they were quickly forgotten as you had made this large complex a haven for yourself and Oliver. With it becoming winter soon, surely you can fix it up before the cold weather hits!

    Things were well, despite you being only a foot tall.

    ...Wait.

    What do you mean there's now 10 Skeleton Monsters taking over?!

    Welp. Guess you have two choices here;
    Put your stealth to the test and see how long you can last
    OR
    Hurry and get the hell out of the home!

    What will you do? What awaits you? Will Oliver and you survive?!
