Summary
As you walked you failed to hear the screams of terror of a bus going over 100 miles per hour and the sounds of it starting to bust down- it speeds near the sidewalk—the people in it shriek. Their blood curling screams didn’t occur to you, your headphone quality being way too good. Your shoulders relaxed as you stretched your limbs; very much unaware of the danger and pain that would very much make your life way more miserable. You should move out the way. But- likewise, you are unaware. Of death flickering and time excited to cut your strings.
The bus is almost out of energy- and has been stopped.
Or so people thought.
It began to tilt- right where you were very much slowly walking. Andddddddddd—
It didn’t crush you to death.

Summary
It's been three years since you fell into the underground and found a family among the monsters of the Ruins. You love your life here with Mom, your ghost buddy Blooky, your prickly friend Flowey, and the host of Ruins monsters who have accepted you as their own, but things can't stay this way forever. Your friends deserve to see the sun, and there's a prophecy to be fulfilled and a barrier to be broken. Your determination pulls you onward.
The only trouble is that you'll have to make it through an underground full of monsters clamoring after the red SOUL in your chest, and each day as circumstances become more dire they lose a little more hope. This is a more desperate underground than the one you landed in. The odds don't look good for one pacifist child with a stick.
Of course, you aren't completely outmatched. You've spent the last three years training for this moment, and you don't intend to let anyone hit you.

Summary
The Barrier's broken and the monsters are stepping out into a Surface they've dreamed of for years uncountable and forgotten. The human that helped them break through is at their side, just as unfamiliar and unsure about the Surface as they are. Upon first glance, the monsters stumble upon another human as they emerge from their prison. A human like any other, but to the monsters 'any other' human has been instrumental to regaining their footing on the Surface. Will this one be too? And are blushed cheeks something every human wears on the Surface? Come along on a journey with humans trying to understand magic, and the memories that follow. Following not as candles that warm, but as shadows that haunt. The human condition changes ever so much when exposed to magic, but how much? And how much can one human take before becoming determined?
A smorgasbord of events from tidying up a goat family to magic of the soul!

Summary
Existe uma história que todo mundo conhece, uma que não precisa ser repetida. Mas o antigo misturou-se com o novo, dando à luz uma obra composta pelo imutável e por aquilo que mudou. Oito humanos caíram. O primeiro foi perdido, assim como seu irmão. Mas último não era mais o mesmo. E um dos outros seis era um pecador. A história que todo mundo conhece ainda existe, mas mudada. Transformada. Não é mais a mesma história, mas, ao mesmo tempo, é. Medos antigos e memórias ruins transformaram-se em agressividade e raiva. Certezas e fé transformaram-se em dúvidas e receio. Uma jornada difícil transformou-se numa jornada ainda mais difícil... mas muito mais recompensadora.
E com tantas coisas iguais misturando com coisas transformadas, eu não consigo não me questionar: o que mais vai se transformar? E o que se tornará?

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
Two souls in the Underground, intertwined by fate and by a prophecy that keeps them apart.
Heads up before you read:
In this fic, Chara is alive and far from a good person. They’re not a mindless killer, but a narcissistic kid. This is not a fluffy Charisk story. Chara and Frisk’s relationship is deeply toxic.Please look at the tags before you continue.
I've been experimenting with third person for a while now, and I've grown to like it a lot more than first person. For those who came from my other fic, which I promised a sequel for, I’ll try my best, but I’m not sure how that will go now that I’ve fallen in love with third person and started a new long fic. Please don’t be angry I will try to finish my other fic as well.

Summary
To my sister, assuming she finds this: PLEASE DON'T KILL ME! I saw the ship listed in the list of ships and was intrigued. I'm sorry.
To anyone confused: She and I know what I'm talking about. If she doesn't... Well, I'll survive for sure, unless I do something dumb and show her it. If she does... Well, I'll need to pray.
Credit for the idea goes to a Discord friend of mine, Voltage, who isn't a fanfic writer, but came up with the idea.
Credit for each individual fandom goes to their creators. I am none of them.
Credit for the story itself, however, is mine.
I kept forgetting, but since I remember right now, allow me to announce that...

Summary
“Not so fun being stuck in some loop right? Trying to fight to protect what ya got, not getting a choice in it. If I had the choice I wouldn't remember either.” The words oddly felt comforting. Link let out a slow breath, closing his eyes for a brief moment.
He didn't feel alone for the first time in a long time.
And that?
That was terrifying.
“To be honest, I kinda gave up a while ago. Just sat back and let the chaos go on, felt like nothing I did mattered anymore. Everything would just be reset anyways. Stopped caring what happened, that was until you showed up.” The skeleton’s eyes bore back into the Hylian.

Summary
Kris was done. After a couple life-changing months, the Roaring was gone and the Angel was banished. They would need time to process the new happy life they now lived, and time to grieve the interdimensional invader they had grown so attached to, now separated from them. But first, it was time to check up on how hometown had changed after experiencing the Roaring and the power of the Dark Worlds.
Meanwhile, Ralsei is very confused as to why the narrative still feels like its moving. Weren't they supposed to reach an end? With their connection to the upper layers cut off, what could possibly be keeping things moving, and what did that mean for them?
This work is based on the events of Persistent Variables by BewareTheDragon1. It takes place the day after chapter 99 (so, before the actual epilogue).
