    Summary

    Nightmare and his gang encounter a mage and decide you know what? Their castle could use a decent maid. Yet, as in any fanfic under the sun, there's a twist, and there's something more to this mage--who requires Nightmare's special brand of magic to stay sane. Diana is soon saddled with five skeletons who seem more intent on annoying her to death than anything, and despite all rationale, finds herself drawn to their dark leader for reasons beyond even her comprehension. Too bad it seems like everyone in the Multiverse seems hellbent on getting between her and Nightmare.

    Started out as a reason to write Nightmare porn and ended up having an actual plot. Lord help us.

    There are whispers of a legend that follows Mt. Ebott, simple folklore that states that any one who dares approaches, HUMAN and MONSTER alike, never return. Naturally, this legend attracts Kris, Susie and a very hesitant Noelle like moths to a flame, and they go to explore it.

    Little do they know, an adventure of HOPES and DREAMS awaits them. Will they survive? Or will they crumble under the weight of a mirror?

    Summary

    This fic will compile all the fics I write for Undertober, which is an event with a prompt for every day of October.

    The fics here do not follow a sequence and can be read in any order. Most of them will be general, though some ships may be included. All of them will be canon compliant or adjacent, and will include both Undertale and Deltarune.

    You can also read find me on tumblr at
    https://a-snow-decahedron.tumblr.com/

    I will tag most characters and ships as they show up.

    Summary

    [[Pre Deltarune, before the phone calls stopped]]

    Working in the Queen's mansion was too good a deal to pass up. A Lightner with nowhere to go but up, you jumped at the chance to save yourself from a life on the streets. Taken under the Queen's explosive wing, you enter a life of servitude and safety.

    One day, a new guest arrives, invited by your Lady Grace--An Addison with nothing but fame and fortune on his mind. You're entrusted with his care by Swatch, to cater to his every need (within reason). Soon, you learn that this job is far more difficult than you thought, and perhaps the Queen was simply out to get you. For a good laugh, of course.

    Too bad for the Addison, this "Spamton", you weren't going to take it lying down.

    --

    [Story takes place before Spamton's fall, and before the events of Deltarune. Reader is gender neutral, and their appearance in not described. This is a story for those who are looking for a character driven narrative]

    [A SLOW burn. There will not be smut in the first few chapters. This is a character piece that will eventually have romantic/sexual elements.]

    Summary

    *What would you do if everything you thought you knew was a lie?*

    Just when Frisk returns to Sans, the blooming flower has to make a deal with the 'devil' to save her family from a horrible memory and sold her memories.

    But, as the story begins again and she slowly gathers all her memories back, Frisk had to wonder:

    Which story is true? The one she thought she knew or is there more?

    Summary

    A bump in the road slightly interferes with the journey of the small hearse.
    -Did you see that crazy? - Says with enthusiasm the uniformed man in the passenger seat in front of the transport car.
    -Which? This case? No big deal, it happened inside the interior where everything is abandoned, it must have been some college prank that didn't work- The old man concludes smoking a cigarette at the end, one hand leaning on the window and the other on the steering wheel.
    -Did you see the body?
    - No, I heard from a policeman that the body is so broken that I couldn't see what was right, there are only patients in this city.

     

    That is true. Sick, mad and ignorant, idiots oblivious to the truth that there are more creatures at night than those who walk in daylight.

    Summary

    What happens when a magic-based skeleton and a science-based human start examining their biology? This, apparently. Largely just a collection of various horrified reactions to human physiology, with some sprinklings of monster physiology.

    This version contains masculine pronouns (he/him)!
