You always knew you were different from the other kids. You knew things the others could never remember. Like how sometimes monsters were on the surface and they disappear just as quickly. You want to get down to the bottom of it and fall down. Ready to learn things you never knew about yourself?

Nightmare found a young child a long time ago. When they fell into a coma it sent him over the edge. several hundred years later the child wakes up in a castle of darkness, surrounded by people, er... skeletons, that they don't know. Now they are being raised by murderers, cannibals, and world destroyers. Oh yeah! And their Uncle is the god of Death. Fun. WARNING (but not really): This story has been known to give people heart attacks and possible death from wholesome cuteness. I am not responsible for said medical emergencies or deaths. Read at your own risk. ~~~~~~ || Few things. 1) The first couple of chapters are going to basically just be Nightmare, but it's for plot reasons. 2) Dream is definitely going to be a little ooc. Don't like it, don't read. This is just for fun. 3) Like I said, this is just for fun. So, updates are when I feel like it. 4) I'mma try to keep the pronouns for (Y/N) gender neutral, but I may just drop that at some point. Depends mostly on what you guys prefer. 5) any art or videos added are not my own unless explicitly stated. Cool? Great. Let's get started.

Y/n was and/or is a very sweet child, unfortunately for them they weren't treated very well by their mother or father, Y/n was abused and didn't have anyone. Fortunately one day y/n got scared and ran away from their parent that was abusive. Y/n's au is Dreamtale While the second part of this story will be inside a different castle... Partially, this story has abusive and angst. Y/n had no friends, they did not go to school, nor did they have any Familiarity's with the outside world. It was all dark for y/n. The only thing y/n could do was see outside the window, and even that wasn't good enough for them. The door was aways locked and there was no way for y/n to get help from anyone... Until one Day...

You were an average kid, somewhat having a older mind than most of your classmates. you had always been into the undertale fandom, and even knew almost everything about the aus and soul colors. while what seemed like a normal day at school quickly turned around after a huge bang struck the class room next door. in this story y/n is nonbinary and 12-16 years old. But more interpreted as 14 I post a new chapter every 3 day and 5 days at the maximum. WARNING: this story will mention some forms of slight emotional harm. And Sexual abuse. Readers be safe. Please if you are in any danger, contact someone. You are not alone. With that aside enjoy the story . This story is finished as of September 1 2022, I encourage you to read my other story "Our Disturbing Love" And in the next month or couple weeks I plan on creating another bad sanses x reader.

What if someone from our world died knowing a lot from the undertale and their multiverse/underverse? What if that person also knew about the balance and didn't creat too many aus? Also they dont like creating sad au's like flowerfell or places they end up like dusttale or Horrortale. Yes they did make au's and may have not known what to call them so they took some names that they knew and remembered from the movie/game/their world like horrortale etc. But they also kept a better eye or eye sockets on his au's and their originals.

(Sans × Gender-Neutral! Parent! Reader || Slow Burn) Moving from a backwater town to a city bustling with human and monsterfolk alike, some things begin to change both for the better and the worse. What was left behind comes back to bite at you in the most unexpected times, current progress being put in danger as a result. It's hard to move on, though it's equally difficult trying to stay loyal to what you believe is right. With an adoptive seven-year-old son and the remnants of a recent divorce in your hands, your goal is to move on and adjust to life with monsters, these becoming an important part of your life -- one of them in particular reigniting the spark you thought gone with your ex spouse. • • • *The following story is a re-write of the first UT fanfic I ever managed to publish on the Internet. *Cover image belongs to Evie Shaffer. *Undertale belongs to Toby Fox. *You belong to yourself.
