    "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! ━━━MOST NOTABLE RANKING: #1 in sansxreader, horrortale, something new and badsanses on 23/12/2025 #1 in undertale on 25/12/2025 #3 in bittersweet on 24/12/2025 #5 in reader on 24/12/2025 #19 in sans on 23/12/2025 ━━━━━━━━━━━━━━━━━━ 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 '25 008 ━━ December 22 of '25 009 ━━ December 23 of '25

    ONE-SHOTS I'm just so obsessed with inserting myself into stories that aren't mine. So, this is a book with miscellaneous stories. Mostly FGOD Error stuff, but I'm leaning into making character inserts, or whatever. I am here to abuse my writes of freedom. Enjoy or Leave, thank you!

    "Now listen here, honey, the rules that you have to follow here, is very simple. Rule #1 : Don't make me and any of my followers angry ! I don't think you want to end up in a really bad state, do you ? Rule #2 : You have, to follow and listen to me ! When I say something you have no choice but to obey ! I, am stronger than you and you, well, can do nothing against me, you are only a weak human my dear~ Rule #3 : Don't try to be friendly towards us ! As I said you are only a weak human, you are nothing to us. But there is one rule that you must never, never break at all coast so here is the Golden Rule here : don't attempt or even succeed to escape from this place ! You're going to stay here forever, so I'll let you one friendly word my dear. If you dare to break one of these rules, you're gonna be punished and believe my followers, you don't want to know what it looks like when you don't behave, so if I were you, I'll be wise and won't be too stubborn, understand ?" (A/N) : The drawing is made by me (this is the oc) and i'm very proud of it 😁😁 I know that these type of stories are not original but meh I don't care, I still wanted to do it so there it is enjoy ❤ PS : None of the characters are mine except the OC and I'm french so don't expect me to be perfect in english, also the characters used (except the OC) is fanon most of the time, I am aware that a few characters don't act this and this way, it's just a story alright ? Enjoy.

    Bill sans. He is a happy, go lucky skeleton who made deals with people and was with the bad sanses. Nothing much more, right? Wrong. His past stays with him no matter what, despite his cheery façade. Will his friends learn of his trauma, or will he forever be Bill, that happy deal maker? Aka, I can't find enough Bill sans angst, so made some based off of my AU There will be two OCs in here. If you want, I am willing to re-write this book without the OCs
