afterdeath concepts dreammare poth sanscest story undertale undertaleau

These are concepts that I may or may not be planning to write or finish, but some of them were interesting enough that I figured I could share in the many wonders of my convoluted mind. 
I shit you not, I have a lot of these. I'll just frame a story concept on a whim and then act surprised when I find it 4 months later.

Is the cover for this fancier than it should be? Yes, but we're going with it anyway.All Rights Reserved

Dreamcember 2021 by WintxrCherry

It's Dreamcember everybody! And I'm gonna be doing at least one for the entirety of the month! The only catch to this is that It's allll gonna be ErrorDream/Insomnia. If I'm gonna do other ships then it would poly with Insomnia, so yeah :D Just a warning but I don't make Error the top in any of my books, as I believe in bottom Error Supremacy hehe adugyfhjm There will be warnings in some chapter as I write fics and tragedies. I don't write sin though, well I do but I will probably never publish it lmao. So yeah, Fluff and Angst! But mostly Fluff cuz why not Also, if you do not like any future DreamErrorMare, or just poly in general, I will give a warning when the chapter is mentioned! Book cover does not belong to me whatsoever!! Anyways, without furder ado, let's get into the the book!

Undertale:Secrets by ItIsComic

Remaster on my page - check it out! Sans has had an interesting past. A past that even his beloved brother barely even knows of. A past that he wishes could remain a secret. But when the questions start being asked, what does he do? These questions seem so little, yet they cause so much to happen. One little question. "Who is ??????" can change so much. A chain reaction from a single sentence can cause an entire world to crumble. Or maybe two. This is my first book so dont expect anything great. Inspirations: The "Better Times" trilogy by: @ANinnyMouse42 "Royal Blue" by: @dealialestine Started: 24th May 2021 Finished: 29th December 2021 A full 7 months of great fun with this book! Cover art by someone? I couldn't find the original owner :( Undertale by Toby Fox

Determination - G!SansxFrisk by Toasty-Writer

Frisk just wants to save monster and humankind, but does she have the determination to do everything she wants? Especially as she has now been blamed for the terrible crimes committed by her sister. G has stopped caring, but can this infuriating woman who becomes his neighbour pull him back into the world and seek for justice again. I'm so bad at descriptions :/ I'm delving headfirst into fanfiction. You guys may not like this story or even read it but I'm going to try. This is a Gsans and frisk story, there will be an attraction between them but it may be slow :P I do not own the characters or their respective AU's. I'm simply throwing my own twist into the mix hoping you like. I do not own any of the art featured in this book, they are just all amazing. Will involve some moderate language, violence and trigger warnings, hence the mature rating, I will warn at the beginning of chapter if there is a trigger warning.

Undertale - Life Outside the Loop by Livathane

It's been seven years since Frisk set the monsters free from the underground, seven years since her choice to return to her human family. Magic is seeping up from the ground, slowly granting humans magic, spelling danger for humans and monsters alike. What's worse? A dark, murderous monster with terrifying power to possess is powering up through the genocide of alternate universes, bent on the destruction of humankind. (note: the cover is just a place holder until I figure out a proper cover. Secondary note. Current cover is purely because I feel like it. Third note. Aside from Plumetale. I don't own any of the AUs)

When Worlds come together by Honey_Bee669

I've seen some Undertale fanfictions where readers and original characters are sucked from our reality and transported in to the reality of Undertale and it's several aus. I got inspiration from some of the stories, I don't exactly remember the name of the stories I apologize but I give credit of the original idea to who ever came up with it first. any how, instead of the character staying human, once they are transported they're turned to skeleton, so the magic in their body can get use to not only the transfer through the void, but so their body can be use to the magic drifting around in the monster world. cover art is made from a picrew dress up/make a character site. all credit to the creator of the picrew! slight trigger warnings for those in need racism towards monsters harassment transphobia homophobia slight panic attacks here and there onwards to the story!

Undertale : Secrets (REMASTERED) by ItIsComic

Sans has had an interesting past. A past that even his beloved brother barely even knows of. A past that, despite being so long ago, always finds a way to bite back. A past that defines who he is - but he longs to erase. A past that doesn't let go, it clings to him despite his endless attempts to escape. And when someone finally attempts to uncover the veil, and fails in the process, what happens next? This book is a complete remake of the original Undertale: Secrets that was made nearly 3 years ago. By remake, I mean that this book takes the general plot of Secrets and basically "tries again". This will reuse elements of the original and cut out the parts I don't like while adding my own new ideas, effectively creating a new book. Whether you liked the original or didn't even read it, I hope you like this!!

$UnderSwap Papyrus x Girl!Reader! - What is this feeling? - {DISCONTINUED} by _Daddy_Pina_Coladas_$

Edit: I'm sorry but this book is discontinued. I lost interest in this book and I couldn't do anymore chapters. I'm sorry but I'll maybe put some chapters in at time to time. So yeah, I apologize for discontinuing this book. P.s the picture cover isn't mine and my username used to be TMNT_DonnieLover(so cringey >///>)) Okay this is gonna be a different story from the other stories I read. So please.... Don't hate on me ________ Its about a girl named (Y/N) (L/N) who fell down Mt. Ebott She met monsters there and showed them love and mercy. She even started to have a crush on a lazy monster. Sans. She loved how he smiles. She loved how he kept saying his jokes to you. Most importantly, she loved how he asked her out. She obviously said yes and they were dating. They told everyone the news. Undyne, Alphys, Papyrus, Gaster, and even Jerry! They were having fun until. The girl started to glitch. She couldn't save and she couldn't stop the glitch. Wonder what she do next? Wonder what's gonna happen? What choice is the girl gonna make? Book was inspired by @Random_Fan_Girl1738, @SilentObserverWrites & @pocokitty

Don't Forget [Sans x Female Reader] by GabrielXander

You would think that with how shit your luck is, you would've been dead day one since falling into the Underground filled with scary monsters and a few spooky skeletons. However, much to your surprise, that did not happen (yet). You know how you ended up here, but you don't know... HOW. You're actually in the GAME Undertale now. And to make matters worse, there are some people who KNOW. You're surviving the best you can, but things are only going to get weirder from here on out. Gaster apparently needs your help? You're using the DJ to go to different AU's? You are gay now?- Okay, maybe that last one is just a joke, but still! You can only hope that your instincts are enough to keep you alive in these trenches. On God, they tryin' to drown you in this hoe! {Available on Patreon, Quotev, and Ao3 under GabrielXander}
