    Summary

    I have no idea what to put for the summary yet. This is a reader-insert story for Swaptale, with a Papyrus/reader relationship down the line.

    Your goal is to get through the Underground alive, and you'll have decisions to make along the way. Friends, Enemies, accidents, coincidences. You're not the first human to fall, and you won't be the last. You'll have to stay Confident if you want to survive.

    But that's easy. Getting out of the Underground is hard.

    Summary

    Alrighty, then this is the Mermay Challenge that I have gone with to participate in this year. The prompts come from skumhuu on Twitter, so credit goes to them for designing it all. I do not have great knowledge and most of this comes from the headcanons and stuff I have seen.

    With that out of the way I give you Levianthantale prompts

    Summary

    Foxfield High School, supposedly peaceful for a time, has been facing an increasing number of dangerous incidents lately for some inexplicable reason. Isaac Beamer, obscurely known as Ink, resident bored artist, along with Edward Quinton, otherwise known as Error, school king and basketball player, keep compulsively involving themselves at every passing opportunity, and the constant threat of their mysterious powers being uncovered continually looms.

    The number of students with secret powers keeps increasing, as does the number of people who seem to comprehend the existence of otherworldly forces. Among this chaos, who can be trusted? Connections form and break, secrets are revealed, hell breaks loose, and the truth slowly surfaces.

    Summary

    Mildred went on a three day solo hike to get a break from work. She didn't ask to fall down a hole. She didn't ask to lose her gear.

    And she especially didn't ask for the murder-happy monsters.

     

    (Or, that one time some kids befriended the homeless woman in the forest.)

    Summary

    After getting to the surface after so many years of isolation, one would think that positivity would come easily. That's what Sans believed, too; wishful thinking be damned, because happiness never seems to come easily to the poor guy. After Sans discovers an unnerving photograph, he begins to dwell on things he can't remember but can't exactly seem to forget either. Will his ominous past finally consume him, or will he be able to free himself from the underground's suffocating hold, especially after so many years of being left in the dark?

    Perhaps all he needs to escape the shadows is for an old friend to light the way.

    Updates slowly (but it does update)!! Apologies in advance for pretty much everything.

    Summary

    Asgore was quite the conundrum to Sans, mostly because he was just so...nice. Sans knew probably better than anyone what Asgore had done to the human children who came through the underground. Even if he hadn’t killed them himself, he had still given the order. He had still told everyone in the underground to kill them on sight. But, talking to him, there was absolutely nothing that would’ve made Sans, or anyone else think ‘yeah, this is definitely a guy who’s hellbent on the destruction of humanity’.

    Summary

    The story is also called; I don’t want too, so I shan’t.

    Error has had enough.
    He didn't choose this, he does NOT want this responsibility.
    and on top of that, he feels like he is missing something.
    Missing memories - he can't even remember his past.
    Nothing past arriving in the blank Anti-Void.
    The dreams won't leave him alone, Thinking about them give him headaches
    And 'Fate's Harpies' aka the voices are still bugging him when he's in the Anti-void...

    So he decides to go on strike. He's taking a holiday from destroying AU's;
    no matter the consequences to the Multiverse.

    Its a Reaper/Error/Nightmare Poly.
