Summary
Years pass. People grow. The world moves on without you. The Angel grew content with that for a while. It still hurt whenever they thought of the world that had long banished them, but something new pulled them out of the depths. Now, the Angel walks amongst friends who swear that they will not be banished. Kris, Susie, and Ralsei mean everything to them. Maybe this time, their banishment doesn't have to be as set in stone as they thought.
The Roaring comes. The light falters. Everyone falls.
A desperate connection is established in an attempt to save what remains of the Angel. If they fall, all hope will be lost. The world that banished the Angel long ago has forgotten them, but they have not forgotten it. This connection will have to be enough. Even if the rules have changed irrevocably, the Angel's one goal remains the same: Find them.

Dualtale AU: Two sides of truth by ED_Soul
Fandoms: Undertale (Video Game), Underverse (webcomic)
18 Oct 2025
Tags
Summary
Description:
This story is based on the distant and little-known Dualtale AU,where nothing is as simple as it seems. In this world, unlike the original Undertale, monsters were never trapped underground. But what was the price for peace between humans and monsters? And how is it connected to XGaster, when these events unfolded long before the X-Event?
(Features characters from Underverse and Undertale,adapted for this story.)Author's Note:
In the Dualtale AU,the famous rule "Kill or Be Killed" is replaced by another:
"Speak out, and you will be silenced."
This is a universe built on lies and dark secrets that everyone holds.Every character has their own agenda and their own rules and it's better not to try and learn them.Series

Summary
Their favorite color is golden. Most would assume it's because of the way it envelops them - their golden skin, golden eyes, golden soul that burns with determination. That's part of it, sure, but they wouldn't say it's the main reason. Rather, it's because of the field near their village, filled to the brim with golden flowers. The place was filled with such tranquility and peace that just sitting down and appreciating the beauty of the landscape surrounding them was enough to soothe all their worries and fears.
Until the day others burned it down. The people, the village, the flowers... all of it.
Years later, after life has broken them down so throughly, they decides they'll do anything to bring that peace back, no matter the cost.
A magic-bearing human falls into the Underground, searching for a reason to keep going. They do find it, eventually. It just takes a while.

The Games We Play by FoundUser, Primordial_Rebel_Jester

Summary
There are infinite opportunities in this world. Infinite opportunities for dreams. Infinite opportunities for hopes. Infinite opportunities for regrets... for loss.
There are some memories you would rather just forget...
The old royal scientist knew that better than anyone.
BRIGHT, BRIGHTER, YET BRIGHTER. SO YOU STILL SHINE ON, EVEN AFTER EVERYTHING YOU ENDURED. EVEN THROUGH THE COLDEST NIGHT.
But a story doesn't have to end the same way.
EXCELLENT. TRULY, EXCELLENT. LET US BEGIN THE CREATION OF OUR NEW FUTURE.
Sometimes... a game can have a secret ending.
(A Deltarune novelization that takes some unexpected turns from canon. Based on some theories, and a little bit of imagination, even the unknown can make itself known.)
(Custom Art and beta'd by Primordial_Rebel_Jester. Story by FoundUser.)

Summary
This is a story about a group of broken people, simply existing together—breathing, interacting, without even forcing you to relax.
Most of the characters chosen for this story come from source materials that already involve severe trauma.However, there will be no further depictions of gore or violence in this story.
And there will absolutely never be any sexual innuendos.(Off-colour jokes, if any, will be strictly adult-to-adult—and never flirty.)That said, since I tend to let characters actively explore their own trauma, there may be mentions or descriptions of past events. (Which is why I’ll include trigger tags in the notes below.)
Don’t worry, there won’t be any cross-universe romantic ships.
Some Original characters appear in here, but the majority of characters in this story do not belong to me.If you feel a character seems a little out of character (OOC), feel free to bring it up, and I’ll consider making adjustments.
However, if it’s only a slight difference, it might simply be due to different interpretations—after all, “There are as many Hamlets as there are readers.” -
