Gather children, listen well, harken to the Under Tale.

Summary
It’s done, after all these years, monster kind can finally be free of their prison in the underground. But not all is well. A specter from the past haunts Frisk, and only by learning to move on from the past that never was can they both find peace. Meanwhile, another specter haunts the world. A war is brewing once again between the ways of old, and the way of the future. Dreams of world revolution and a classless society reignite, and soon the world will be divided between those who wish for a brighter future, and those who cling desperately to their own past that never was. Soon, the recently emerged monsters will need to choose what role they will play in this conflict, and what their place will be in the world.

Kingdomtale part 1 (pacifist series) old by melodic_melodies
Fandoms: Undertale (Video Game)

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.”

Summary
What happens when a certain human child ends up in hell with nobody with them except the friendly murderous ghost they befriended and their own determination? Will they ever be able to go back home? Or will Frisk, in true pacifist nature, end up befriending these non-humans as always? Stay tuned and lets find out!
(DISCLAIMERS: I'm going to update tags after posting chapters (idk how to do it while posting because I've not written that many fanfictions before, so I'm sorry), a lot of this might not be accurate to the characters (I'm going to try) and the chapters might be short/ infrequent updates, also Frisk and Chara use they/them pronouns)

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. -

She certain that she's never seen anything like this before yet there's a nagging familiarity she can't quite place, nor can she remember how she got here.

But can she pay the price for their freedom and still have anything left of herself?
