    Summary

    Error is done with everything and everyone, with the abuse, with his job, with murdering, with being the scapegoat and with Ink, so he just falls into the void to finally die and let the multiverse destruct itself...
    Except that he didn't die, a bunch of people followed him and it seems that they're in a different multiverse...
    This DEFINITELY wasn't what Error had in mind
    Well... At least that multiverse is still going to destruct itself, right...?

    FGoD Error concept belongs to Harrish6

    Summary

    Needing a new place to live after your old landlord had decided they wanted to sell the flat, you end up living with your mom; But thankfully it wasn't for long as the lanky skeleton that was a constant customer at your work place caught wind of you trying to find a place to live.

    He kindly offers you their spare room; which you accept of course, because even tho you love your mom, independence is a thing and you really wanted it back. Even if that independence now came with not just one, but two (handsome) skeleton monsters.

    #and they were room'mates' #oh no the're hot!

    Summary

    You've been neighbours with the Skeleton brothers for years, and you've stuck around after all the stunts they pulled. Helped them learn the basics about humans as they did the same with you and Monsters. You were there when Sans almost blew up their home by bringing their eldest brother back from the void.

    You're pretty open about how you feel and they know exactly how important they are to you. If that's one thing you appreciate about Monsters is that they are normally very straight forward about how they feel and appreciate the intent behind your words and actions.

    But then the Mad scientist Duo that was reunited with the two older brothers were testing your little patience as they messed with the machine again and brought not 1, not 2, but 3 whole different versions of themselves and Papyrus into existence.

    These boneheads are so lucky you're a persistent soul.

    Summary

    It's said that every little girl from the tender age of ten when they first receive their soulmate tattoo can't wait to meet their soulmate, the one perfect person destined for them. The only problem is, you weren't every little girl, and you didn't receive just any ordinary soulmate tattoo. From the age of ten you'd had to stare at the words "GET OUT OF MY WAY ALREADY YOU FREAKING NOBODY!", and know that's exactly what your soulmate would think the first time they ever laid eyes on you. That you were just some nobody, and from that moment on you no longer had the desire to meet this soulmate who apparently thought so little of you upon first glance.

    But then you do meet him, and he changes everything.

    Summary

    You saved everyone.
    You made the right choices.
    (You've made some wrong choices.)
    And you've made choices that you're still not sure about.

    Welcome...to the second part of diamonds and dust (gold and rust), which I now unofficially dub, "the squeakquel," of my series.

    Summary

    *The golden flowers must have broken your fall.

     

     

    It took one wrong step and Chara found themselves hurtling into the caverns below, caverns overrun by monsters who’ll do anything to claw their body apart and take their Soul. Cruelty tainted their soul’s and they seemed to follow only one code of conduct: “Kill or be Killed”, leaving the fallen human at a precarious position; one that guaranteed their possible death.

    Holding onto their hopes that they may survive, Chara travels through the caves to find their way out of this nightmare and possibly change and free the monsters as they go along…

    …and maybe change for the better themselves.

    Summary

    You always told him, “stop messing with that machine, Sans.” You swore you told him that on an almost weekly basis, yet – despite your words of warning – he never once listened to you. That’s why you’re now stuck in your current situation: being held by a skeleton you’ve never met before, but seems oh-so-familiar, with a sharpened bone attack raised to your jugular. You spoke, voice laced in annoyance and frustration as you stared at Sans who was across the room, sweat dripping down his skull, “I told you to stop fucking with that machine.

    Summary

    You live in Ebbot City, but on the shitty part. Living your whole live in the Kill or Be Killed world, you never thought of finding a lover. Never crossed your mind. All you wanted was to have fun in live, make friends, and make sure Tianna, your bestie, had the best in life.

    So when you meet a really REALLY tall skele-dude you never thought you would fall in love with him. You're afraid to tell him your secret because it's one of those "I'll have to kill you if you tell." You have to find a way to keep the people you love safe and a way they can live free. Not hiding or being afraid of who they really are.

    Will both your love be enough to go through the journey together, will you have to live with a broken heart, or the guilt of dusting Him?
