Summary
Magic sears through my veins, but I am determined to use every advantage I have.
Okay so.. pretty much... you have lore (and trauma).. these silly skeletons somehow get pulled into your universe and you have to find a way to get them home. Lots of action, lots of gay. They are gay for each other and for you.. maybe... at some point.. might take a while.
I do NOT consent for my work to be used for AI: prompts, teaching, character bots, or anything else related to AI.
Undertale belongs to uhhh Toby Fox or something idk..

Summary
The strong nuclear force is defined as the strongest of the four fundamental forces of nature. It is the force that binds protons to neutrons inside of an atomic nucleus. On the quantum level, it also binds quarks of similar charge and direction together in order to form protons and neutrons.
The summer after her graduation from undergrad with dual degrees in biotechnology and theoretical physics, the world around Vera Jefferson changed. An entire new race of people poured out of Mt. Ebott, the namesake for her university. The monsters that now populated the militarized zone around the campus and base of the mountain were strange, but kind. Having made quick friends with the sarcastic bartender/owner of the restaurant across the back alley from her apartment, it seemed as though her world had changed for the better.
Once she starts the first semester of her PhD, she realizes just how true that is when she meets some of the other monsters around campus. Life may not be easy, but with the help of the people she went through undergrad with and her new friends from underground, she feels for the first time that she just might make it through.

Summary
A tap of fingers on the counter. Sans doesn't react. There's a strange noise, reminiscent of a buzzer, and then a more insistent tap, right next to his auditory canal. Sans doesn't stir.
"Sans Undertale," a strange voice above him says. It's difficult to even call it a voice, it's more so a sound of plastic and metal clicking together, audio distorted as if played back through a broken record. "Don't you know how to greet an old pal? Open your eyes and shake my hand."
Well. He's heard that before.

Summary
Life is monotonous and dull, but it’s okay. You’re fine.
Assignment after assignment, test after test, meaningless conversation after meaningless conversation. It fills the void like a flitting firefly in the smoggy night sky, a brief flash of light— followed by an endless expanse of nothingness.
That’s okay. You’ve grown accustomed to it like a goldfish stuck in a glass bowl. You swim, back and forth, over and over and over again until you can’t anymore. It keeps you occupied, distracts you from your lonely, miserable existence.
Until you meet someone who simultaneously fills the void, and drags you so much deeper into it.

Summary
*None of this art is mine. ALL ART BELONGS TO ORIGINAL OWNERS*
After years of confinement, monsters have finally escaped Mt. Ebbot. Initially, the world struggled to accept their presence, but over time, humans and monsters forged a fragile peace. Yet, beneath the surface, something remains amiss.You carry the weight of a fractured soul, scarred by past traumas. In a world that seems to have moved on, you're left to navigate the shadows of your own pain. But you're not alone. In the depths of this new reality, you cross paths with another broken soul—Sans.
Once a figure of terror, now a shadow of his former self, Sans understands the darkness that clings to you. Together, you embark on a journey of healing, trust, and the possibility of redemption. But as your bond deepens, so does the question: can two shattered souls truly mend each other, or will the weight of their pasts pull them further into the abyss?

For The Love Of Wine by Missh3h3

Summary
You were, honest to the stars, hopelessly in love.
He was too charming for your own good. A silky voice, elegant fashion, and diverse skills that couldn't possibly be matched by another monster. Perfect in every way, he was.
"I love you," you breathed, a smile lifting your lips. "Love you so much, Sans."
Wine smiled back as he rested his phalanges on your cheek. "I love you the most, my dear."
You laughed. "That's impossible. Just accept my love, dork."
Naive, but adorable. He found you endearing in every manner.
But every word you said, oh how he hoped it would be true one day and by heart one day.

Summary
You'd never expected to be one of those people who bonded with a random stray, and if you did, you never expected it to turn out like this. The tiny... blob of an animal was cute, affectionate, and melted your heart before you'd even named him. Unfortunately, not everything is as it seems. You've met this lovely creature before, and he definitely remembers you...

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.
