Monsters can go up to the Surface but choose not too as Humans do not want them there and will attack them on sight but there are some curious Humans who will pass through the Underground and so to ease what ever discomfort they may have some Monsters can make themselves look Human. You the Reader didn't get to know all the Monsters, for the whole 2 years you just worked and relaxed at Waterfall until you met a certain Monster who changes your life and you change his.

    "the healer likes t' sleep. like, a lot." Axe looks at the sole female AND human member of Nightmare's subordinates. She was only ever awake for about 8-10 hours a day, rarely ever 12, it was both fascinating and irritating at the same time. He was damn sure humans would be awake for more hours than that, he even asked Murder at the time if it was normal. Said skeleton didn't give a single care though, his words: "who cares, makes her more tolerable. 'sides she gets her job done." The cracked skeleton just couldn't shake off the feeling that there was more to it than meets the EYE. ━━━PHOTO CREDITS: Whale鯨豚 [@Whale5511] on X! ━━━━━━━━━━━━━━━━━━ DATES PUBLISHED: 001 ━━ July 29th of '25 002 ━━ July 30th of '25 003 ━━ August 1 of '25 004 ━━ August 3 of '25 005 ━━ August 6 of '25 006 ━━ August 8 of '25 007 ━━ November 8 of '25

    You had a happy family and never got a big problem, just that you never believed into you. Your parents tried everything to help you but in vain. One day, you decided to stop bothering them. You went to the darkest place of the forest and end your life. At least, that was what you wished. ( I'll skip the moment in the Ruins, so you'll fall into the snowy forest.) (Btw, I do not own the AU or the characters that are present in Undertale/Underfell) Edit-Some elements of this story might be trigfering and since I litterally have bo idea of how younger thought this was okay, we'll just say that the reader has Stockholm syndrome.

    You're a spy in the midst of uprising crimes, smell of coffee rising in the office. Recently, an unknown figure has been found, causing the sentience of death, the aroma and residue of demise. The streets of Vermont flood with unsolved cases, leaving you-- and others-- missing and confused. It is up to you to find out the culprit of all this unnecessary madness, murder... And dust. But now, caught in a dilemma, you're left out on the facade of a killer, right at your feet. You know that if you take one wrong step, this may be the last breath you'll take. The way you were so determined to put an end to this.. seemingly endless slaughter, how you tracked them down with your own bare hands, thinking that it would save the lives of others-- it was nothing but amusing to that damn skeleton. He could grab your hand-- and lead you into the unknown-- the meanings of this world that humanity had once put aside. Or, maybe, they'll tear you to little bits as you scream for help that cannot be reached. For you, the only thing running through your head was the question of what will go down once you take his hand. Will you be slaughtered in spite, or is there something else much bigger to the picture that you're simply not seeing? You could leave everything behind... And could this misunderstanding lead to more than just being acquaintances? - - - - This is my first story written and published, so expect grammatical errors and whatnot. Also, chapters will not be too long, ranging to an average of about 2000 words or so. The story may tend to progress very quickly, and I apologize for it. Dusttale Sans is probably one, if not my favorite AU Sans, furthermore leading me to writing this story. Reading other people's work really motivated me to make my own work! All chapters will be done over time, hang in there. :) ( Story was *inspired* by "morrow-"/"space sloth"! ) - - - - Start | Oct. 22, 2021 Finish | n/a

    Discontinued - DM me if you would like to write a finish for the story. (This is my first story, hope you like it and bear with me!) Since it was Monday today, it wasn't very busy. Just a couple of people here and there. A slow day. For some reason, you have a TV mounted on the wall in the store that showed the Local News Station. "Breaking news! The legends are true, the monsters from Mount Ebott are real!" ***** Being 5'4, he towered over you. But what freaked you out was that he was staring at you with red pin-pricks used for eyes in pitch black sockets the entire time while shortly talking to his much taller brother. He extended a bony hand to you, which you hesitantly excepted. "Nice to-," You stopped midsentence, retracting your hand from Sans' hand with a yelp. "ha! the ol' buzzer in the hand trick. it always rattles people's bones. heheh, anyways, how are ya?" He said with a deep, Boston accent, chuckling. You are filled with Awkwardness and Anxiety. The beginning is horrible, but it gets better in the end!! I think... __((Art on cover not mine!! The title, name, and background are!!))__ Started: 02/10/2019 Finished: ??/??/???? ON HOLD ‼️
