    Summary

    new summary:
    A long time ago, a skeleton with black tattoos found themselves alone in a white void, in one story, that skeleton went and became beloved by the multiverse that he protected, but in another, in this multiverse, that skeleton never took that journey, and stayed hidden, avoiding attention, the multiverse remaining unaware of their existence for years and years and years...

    until someone, dream, noticed.

     

    (old summery:
    I always liked the image of ink being a homeless hobo skeleton creature with no sense of shame or social norms, having no idea how to math because they have no actually education and basically clinical insane, I also like to imagine that by following his rule of "don't interfere with the goings on of the multiverse" he would act feral as fuck, So this is exactly what this is, dream and blue basically trying to tame the multiverse guardian ink. but like way more plot based)

    Summary

    Y/N is a skeleton who lives with her father and brothers on a farm in the middle of a prairie town based sometime in an alternate war time for monsters. She isn’t a push over. Her job is to hunt and kill ‘sick’ (rabid) animals and keep her farm safe, amidst her father renting the farm land out to the skeleton army who was now stationed to protect their agricultural hub from being invaded by the enemy. If that wasn’t enough, the reader has to deal with her father picking out her mates and sending her away. Did we mention that they are all baras?

    Summary

    (An Underfell illustrated story by ElenArtsy.)

    This story is about Frisk's journey through a destroyed and hateful Underground in which they are not welcome. As they struggle to survive the many enemies on their way, they are forced to witness the tragic consequences of the Tyrant's long dictatorship over the citizens' souls and minds... The rules are strict in this merciless world: it's Kill or Be Killed. Will the young human be able to change to fit and survive this cruel reality? Or will they give in to the unstoppable circle of violence?

    Based on the comic Underfell by me. (https://www.deviantart.com/elenartsy/art/Underfell-Intro-1-3-A-long-long-time-ago-816753512) You can also read the story and find all of its illustrations on my DeviantArt profile.

    It was going good until you were slammed up against shelf in the grocery store by a Skeleton that would claim to be your Alpha. Since then, Your life has spiraled down and you are doing everything you can to keep calm while a giant skeleton follows you around like a puppy.

    Good luck dealing with Monsters who hate you, Alpha’s who want you for then wrong reasons, A human who saved a race of people wanting you too be their older sibling, A annoying roommate , your ‘Alpha's’ brothers trying to kill you for being human and Said Alpha being the worst himbo!

    Summary

    Life had been turned upside down for the past 5 years as the demon hounded her through the multiverse. Throwing them through portal after portal in the hopes that she'd break and obey them. Not only did she resist, she finally broke free of the cycle and found comfort in a home full of skeletons.

    Letting go of the past is hard, but with help the future looks bright.

    Summary

    while the heroes of our story seek shelter in sci's basement (during chapter 27 and 28), Sci, the young scientist, has decided to get away from the group to organize and fix up his lab and to think.

    during his time there alone, his brain cannot help but travel down memory lane and replay the events that led up to their current situation and be forced to face his new reality.

    will he be forced to choose between two seemingly impossible choices? will sci be able to do what is needed to protect his family? he will be needing a lot more coffee in his system before he will be able to answer that question...

    (Perspective shift set during the events of Raising ink chapters 19 and 23.)

    Summary

    It all started with a page.

    And the Lord of nightmares turned to stone.

    Everything took an interesting turn after that event for everyone.

    The question is what happens when characters have access to their script?

    Summary

    When your father brought up the count as a match, your interest was piqued. Count Aster cuts a flattering picture. You know he's educated, and he has never expressed negative intentions towards you. Granted, you'd never been in a room with him without three or more others. That's why your parents talked and arranged the current situation. It's a date, of sorts.

    Summary

    “Tell me, Doctor… you have served me longer than any other. In what ways would you serve me?”

    Feeling as if he were in a dream, Gaster numbly signed, <I would serve you in any way you ask, Your Majesty.>

    The King raised a brow. “In… any way I ask…?”

    Flushing deeper, Gaster signed, <I belong to you. My body, my soul, is yours.>

    His Majesty’s eyes blew wide, then, and his breathing grew heavier. “...You will follow Rudy’s every order,” he managed gruffly. “If at any point you wish to stop what is happening, snap your fingers twice.”

    Summary

    Underfell x Reader story, regular updates now.
    For the first time, a grown up human has fallen into the Underground instead of the usual younger Souls, the last Soul needed for monster-kind to escape the Underground, but, it just so happened that the human would not give up so easily.

    The story is a mix of lore (adventuring through the Underground, trying to achieve the trust route) and romance/smut. It will be feels heavy, just with a buildup to it :)

    The Reader/"You" is AFAB(assigned female at birth, so to say, a body of female sex), their gender won't be mentioned nor will their name (only nicknames), so you can think of them as yourself or whoever may come to your mind.

    -----------

    Content warnings:
    Smut and Romance (both fluff and rough), temporary Death, Violence.

    Multiple smut-scenes with the Reader and various characters from Underfell.
    Mostly slow burns, occasional fast burns will come again and again.
    Has a plot n ideas traveling along with the fun!

    Summary

    “What if I told you that even the big bad wolf had a heart? One that once beat for a certain human girl?

    Would you believe that a mere human could overcome even the darkest spell?

    —Of course not that’s just silly, and now it’s getting late. Beware the wolves, my love..”

    This is an unofficial prequel to Staringback’s incredible fan fiction- ‘Sooner or Later You’re Gonna Be Mine.”

    A fic based on before the fic**

    Chara is a nun working at a chapel in the midst of the Snowdin city that has become an underworld overrun with corrupt mobs.She had never needed anyone, dying was always easy—but living was harder. Not to say that life in the crowded and dirty city she called home was ever easy. And not to say that there weren’t a multitude of ways one could die. But she figured she’d be fine.
    That is. Until her paths crossed one of the most dangerous mobsters in the city. And now she owes him big....

    Now her fate rests in the hands of one W.D Gaster, a hot tempered mob upstart who has his eyes trained on the top of the underworld. And he fully plans to drag her there with him, kicking and screaming..

    Not that she ever had a choice anyway..
