Gather children, listen well, harken to the Under Tale.
A story of a small child, falling into a massive cavern where monsters have made their home. With the help of a certain phantom, the child makes their way through the Underground, making friends & family along the way.

Summary
Suddenly, like a jolt of electricity, a crack of magic filled the room. The hair on your arm stood up straight, and your blanket clung to your body with static. You blinked to see two white pinpricks staring back at you, the only light in the room. You hadn't expected him so soon.
"heya." His voice was quiet and raspy, like he hadn't had water in months. You sat up straighter, rubbing the non-existent sleep from your eyes.
"Hey," you murmured, surprised at how calm you sounded. Weren't you just worried about the tour? But the sound of your rushing thoughts had finally quieted, replaced by his soft voice. "Couldn't sleep?"
"nah," he replied, and you could hear the rueful smile behind his words. "you got room for one more?"
"'Course I do."
⏾⋆.˚
Six months ago, you and Sans left the deadliest arena in the world. Six months ago, you fell in love on camera, and exposed your life to the entire country. Six months ago, you became the Capitol's favorite spectacle.
Now it was time to pick up the pieces, if only everyone else would let you.

Summary
Sans wasn't planning on getting himself a slave. There were just too many mysteries surrounding the human to just let them go. Sans was going to find every little secret of theirs if it killed him. Make no mistake, it was likely to kill him. If only the human would stop sucking up to his brother.
Or in which, the author is sick of people using slave fics to make reader a broken/submissive doll and Sans a dom butthead, so author makes their own story and gleefully tramples over some cliches.

Kingdomtale part 1 (pacifist series) by melodic_melodies
Fandoms: Undertale (Video Game)
01 Jun 2025

Summary
A long long time ago two races roamed the earth, humans and monsters. One day war broke out between the two kingdoms that shared the land. The humans won the war and used magic to seal up the monsters on one half of the kingdom using a barrier, blocking all existing routes by mountain and by sea around the land.
*You can see a sign in the distance. It reads Mt. Ebbot, year 15XX.*
Warnings and description: might contain mentions of abuse, violence, death, potential mentions of rape? depression, attempted suicide, cursing, romance, weird/Toby logic and ships. If any of these topics bother you I suggest you go and read something else. Also this project has been a long process so I do apologize if some things feel inconsistent, remember though this is just one part of a huge AU series I am writing and things will be fully fledged out over time. Frisk is a girl but only uses nonbinary pronouns unless stated otherwise. Frisk is also gonna be unnamed for most of the three part series as I decided it would be cool to keep it close to cannon that way and have Frisk go unnamed until after the final boss fight. You will most likely hear Frisk mentioned a lot as “human,” “child,” or ”kid/kiddo.”

As always, Frisk climbs Mt. Ebott and falls into the Underground. However, this time, like so many others, something is different...
Welcome to Shuffled Reality, an AU where I randomized all of the characters roles (except the npcs, but we don't talk about them). Expect to see some strange and perhaps silly things.

Summary
One childhood promise leads to changes that will ripple through the lives of more than just the three skeletons who shared it. When it comes into the spotlight, the result is a wave of change that will effect lives, families, and even an entire web of nations. Will the luck behind it bring good or bad to the people at the center of it all? Will Blue, Dream, and Nightmare find the love, peace, and safety they so desperately need? What is most important of it all, though, is whether anyone will ever help Blue find the rest of his mother's last gift.

Summary
In this story reader is a female, sorry guys ;^; be warned some graphic scenes may take place in this story! I will put a warning out at the beginning of the chapter if you wish to skip it!
You didn't have a quiet life. Both parents divorced when you were young and your sister was still a baby. Stuck with an abusive mother and father no longer in the picture, (Y/n) tried to make the best of it. Working hard to save up to escape from one hell, you find yourself stuck in another. But this one was different. This one could be the little heaven you'd been praying for.
Monsters are roaming the surface, forming an aggressive Mafia. When one high ranking enters her work, long forgotten memories rise up. Something about him makes him feel familiar to her. He can't understand why she was so familiar either.
Can they remember? Or will the past become buried?
Mafiafell does not belong to me. I'm sort of taking inspiration for this from a lot of places. All characters belong to the original creators! Some OC character's included.

Summary
Monsters have arisen from the depths of Mount Ebbot, from a horrendous place you now know as Underfell. The monsters you have the pleasure of meeting may be rough and stand-offish at first, but once you take the time to know them, you're like one of the (albeit dysfunctional) family!

ECHOFALLS by RubyHobbit
Fandoms: Undertale (Video Game), Underfell - Fandom, Flowerfell (the original)
18 Jul 2022
Tags
Summary
ECHOFALLS is an Undertale AU based off of UNDERFELL and the ORIGINAL FLOWERFELL. if you don't know FlowerFell is actually not a FRANS AU and was taken down because people didn't want to do all the work that I am doing and create a new AU with its own story and have its own ending and its own lesson to get what they want and instead decided to just change a little of the story and make Sans (someone in his 20s or 30s) date Frisks (who in the story was at most a teen but probably still 10). Why I don't know maybe they have a competition with Sans or something. I however feel that is horrible and wrong and I want the creator to know that their story is still theirs and hopefully bring the original back.
The ECHOFALLS AU is an AU where two twin girls fall down a Chasm and wake up in the underground at different times. Both of which change the underground forever. Every time either of them dies a blue echo flower grows on them and has an echo of the last thing that was said right before they died if someone interacts with them. We start with one but end with another, will they be free or will they remain underground in eternal silence and slumber forgotten by the Humans above.
