I wonder... In a timeline where Chara has never succeeded... Just what exactly goes on in the Judgement Hall? Sans has never died. ... Or has he?

After much research and theorizing, I've decided that I'm going to attempt it. It's risky, but I'm so desperate at this point that I'm willing to put my own well being on the line. If I survive, this may just turn out to be very... interesting. This is my thoughts on the origins of Sans and Papyrus, as well as their connection to Gaster. It will be connected to the ZanaTale timeline (or, in otherwords, my Sans x Reader fanfic "When Two Souls Meet"). Loosely inspired by the HandPlates AU by Zarla. Awesome cover image by Dweebycake.

Spoilers for after Undertale and after Gravity Falls! The twins are coming back to Gravity Falls for their winter break. However. The mountain just by Gravity Falls had a strange event a few weeks after the twins left. Monsters from the fabled "Underground" started coming out of Mt Ebott. With their savior, Frisk. Now Frisk and their monster family live peacefully in the nearby town of Gravity Falls. What shenanigans will the twins get up to this time? What will they discover? *This takes place after Gravity Falls' Finale and Undertale's True Pacifist ending!* The original Gravitytale idea as well as the intro music used was made by the amazing Jeffrey Watkins. Check them out on Youtube and their story on AO3! I thank them for inspiring me to make my own fanfiction. This is my first story and first time writing a story, it might not be any good, but do enjoy!

(Basically Dadmare and Dream trying to raise the kid versions of the other sanses) Nightmare and Dream's parents left them with a giant house, a ridiculous amount of money, and tension in the air. With too much free time on their hands, life is starting to get boring. Nightmare never thought about having kids, he always believed he would be a terrible parent. Dream also never thought about being a parent too much, but he didn't think he would mind if the situation ever arose. So... What would happen when fate decided to have the two brothers meet a bunch of kids in need? (FOR THE RECORD: Nightmare and Dream do NOT have a romantic and/or sexual relationship in this story! They are simply brothers who later on help each other raise kids!)

A young girl, Y/N, has one of the rarest soul types- -empathy. She can feel when people are having a bad day which leads her into meeting two skeletons. While one quickly takes a liking to her, the other is more suspicious than anything. Will he ever get over his suspicions for her, or will the looming war between the races get in the way? !!! Trigger Warnings !!! There will be cuss words scattered throughout the book as well as other triggering topics. I will be putting a warning on those chapters as well as a summary at the end of the chapters. this is also a slow burn book, y/n isn't just thrown into everything on the first chapter, it takes a couple chapters for everything to get started. it is a sorta boring start but it really sets you up with the situation and the world. oh right, were also running at like 15-20 pages a chapter sooo. so yea cool thanks! cover credit: HJUGA208 on Picsart for the Sans art, everything else is made by me on canva lol best rankings: #3 in the sansxreader tag :) #1 in the sans tag :))
