Summary
The taste is what drives you. The smell motivates you. The feel of dust between your fingers, the sound of screams and begs echoing in your ears, watching them dissolve right before your eyes.
The sensation of LOVE filling your body.
You had long grown used to the feeling of gaining level after level, over and over all for your entertainment.
When it was all ripped away from you, the emptiness was too agonizing for you to truly focus on your newfound lack of flesh and the magic seeping from your bones.
Kill first, ask questions later.

The soul of Determination. MLP by therandomreader1009
Fandoms: My Little Pony Generation 4: Friendship Is Magic (Cartoon 2010)
30 Nov 2025

Summary
y/n is the soul of determination. They've traveled a lot to get here, going through all sorts of universes and such, but now they've found a very peaceful world and plan to stay here for the rest of their "life". However, they are foreign to this world's magics and way of nature. How will this world react? Can they find a place to fit in? And most importantly, how will they get a body of their own? All this and more is coming now.
A slight warning, the plans I have for y/n makes it so we can't have this world be the normal MLP Friendship is Magic world. So we're gonna need to make the characters of this world anthro, if that's the right word.

A New Tomorrow by SleeplessArcher

Summary
Slowly, it opened its eyes, blinking sluggishly before sweeping its gaze from left to right. Its surroundings were muggy - the ‘blinding’ light was actually quite dim, so it couldn’t see much, but it could tell that it was in some sort of cellar. The floor and walls were made of a dark blue brick, much of which was either cracked or split by plantation of some form. Bits of machinery littered the area, and a plethora of folders, crates, and pouches of dilapidated materials were scattered in random places.
~~~
It felt like it should’ve known exactly where it was and exactly what it was supposed to do. A part of its mind was waiting for a task to fulfill or a role to embrace - but without either of those things, it was left with a persistent sensation of emptiness that gnawed at its chest and made it more anxious than it already was. Its whole world was off-kilter and it didn’t know why.
------------------------
A self-indulgent PMD story about a science experiment trying to find its way in a world it doesn't remember.
Rewrite of 'Staring at the Face of Tomorrow'. That story had a bit too many issues so I decided to start fresh.

Summary
I don't have any vague summary.
But essentially, it's Deltarune with Undertale Red and Yellow sprinkled in.
Kris' SOUL is comprised of three souls, Frisk as the Red SOUL, Chara as the Black SOUL, and finally Clover as the Yellow SOUL.
This AU will also feature UT Yellow characters, integrated into Deltarune. Will they have significance? We'll just have to wait and see...

Summary
He thought that the radiation would kill him. He thought that his time as the Doctor would come to a sad and brutal end. He was wrong. And that was so much worse.

OR
Undertale but the Tenth Doctor replaces Frisk. Fluff, angst, AUs, and timeline shenanigans ensue.

A FINE LINE BETWEEN ORANGE AND YELLOW - Hiatus/Rewriting by MairwynCSulien1990
Fandoms: Undertale (Video Game), Original Work
07 Nov 2025
Tags
Summary
While Aneira didn't necessarily believe monsters existed, she did find the fact that everyone and their dog still did might mean something. Her childhood town of Beddgelert believed in monsters trapped under the mountains near their home that would need a seventh soul now to break out and destroy lands.
Putting this on hiatus because not only do I feel I can characterise Aneira better (writing characters in character is not easy for me), the general plot can do with reworking and yk foreshadowing. Might just reupload chapters once I've completed the story, which may actually get me to update something in a reasonable time frame.
Do not expect anything to be done soon because I am going to be very busy very soon and won't have the time until the Christmas holidays.
Sorry, not sorry, I want something I write not to weigh on my mind how badly written it was, less so than usual - this note is mainly for the singular friend that follows me and may actually read this.Series

Summary
Being stuck in an alternate universe sucks. Especially when Dust and Horror have no way to contact Nightmare and go home. Dust's magic has been acting odd ever since they got here but he's keeping it a secret. And Horror is just trying to protect the other from every monster in the underground desperate to eat. It's only a matter of time before something gives.

Summary
Sans has a mission, and Aliza is a part of it.
She will persevere through anything he puts her through.
She has to get out of this hell hole. She has to help Sans with his mission. It's a good thing these things align, but it sucks that they align in such a way-- Aliza doesn't want to hurt anybody.My work for AI-Less Whumptober! It's all one continuous storyline, this is NOT a one shot book (I'm bad at those lol)

Summary
It's been three moons since Night killed everyone in his village. Its been three agonizing, heartbreaking moons since he had killed his brother.
There's not much to do in a soulless world. This changes, ever so slightly when he hears a desperate call from someone in the abyss.
Night doesn’t know what to make of his new situation, and he can't bring himself to move on just yet from the horrors he's committed. But life demands his interaction and input, so he forces himself up anyways.
Dream would do the same, if they were here. But they're not, so Night might as well pick up the slack.
