    Long ago, before anything other than white existed...there was a seed. This seed begged for care and inspiration despite its reputation; so someone answered the call, and he blessed that seed with his ideas and hope. Soon after, some followed this creator ' s idea and brought us to where we were now; with a little guardian named Dream, and his destiny to save all. || HIII! This is my very first fanfic, so please do not judge if it is not to everyone ' s taste. This idea first sprouted two whole years ago, and from there; me and some of my friends started to create it, so Omh and all others..enjoy!

    Born in a void, devoid of all life, Glitch Gaster had nothing. He had to watch as other Au's got to experience lives and outcomes.. While he had nothing. He loathed to have what they had. One day, Glitch Gaster witnessed the power of 'OverWrite'. He became obsessed with the idea of true power.. The idea of becoming so strong nobody could oppose him. He wanted a world of his own.. But not just that. He wanted more.. MORE POWER. He wanted to become god of a world. So with Inks help, Glitch Gaster created his own masterpiece.. the 'Glitch' button. Using it, he created a world of his design. A fake world.. With nothing real in it. All to be his plaything.. To satisfy his hunger for more power. But not everything goes how you want it to.. One of his creations suffers a malfunction. A glitch in the code.. And suddenly. He can feel, see, hear.. He's.. Real? But with a power hungry god ruling over his world, can newfound sentience really overpower raw strength when your whole life has been a lie?

    "Where am I?..." a soft, monotone voice whispered, its owner looking around. His creation was alive; the experiment worked! "Ho-o-oly sh-sh-shit-t," the skeleton muttered in awe, starting to glitch more. "I-i-itt wor-orked, ho-holy sh-shit!" "What worked..." the doll asked, looking up at the skeleton in front of it. He let out a stuttering, almost manic laugh, the doll simply waiting for him to calm down. "I-I-I cre-e-ated-ed y-y-you," he finally told it, grinning. "Yo-ou-ou're-u're my-y cre-eation-tion." WARNINGS This fic will contain minor swearing, complicated relationships, skeletons, minor questioning of existence, and quite a few shenanigans from previously mentioned skeletons.

    Cold. Everything was cold. And dark. I was so alone... how could I have wanted this? This couldn't possibly be better than before... the warmth, and the light, and the smiles, however scarce. I cried out. I screamed, but it was muffled. I wanted it back. I wanted everything back. I regretted my decisions, my plans, my dreams. I wanted a second chance. **Reborn as a ??? Sans** !!READ THE FINAL ANNOUNCEMENT IN THE FIRST CHAPTER FOR IMPORTANT INFO BEFORE STARTING PLEASE!!

    Based off of Beauty and the Beast. You are living a quiet life when you are forced to flee into a forest to escape a forced marriage. While running, you stumble across a certain someone's castle... Howdy, my darlings! This is Editor Valery. This book was originally written on Quotev. It'd be appreciated if you checked out this book there too! There is a sequel. It'll take me a while to put it on here, so feel free to read the sequel on Quotev whenever. This book was first started in 2019, so the Author Notes from my sister will be old. She doesn't want to change anything, so I'll be the one moving everything here! The Editor Notes will change a bit cause I don't like my notes anymore- Anyway, enough of that. This is a Fem Reader story, so enjoy that. You're all beautiful and amazing and I love you all! Enjoy the book! Mwah!

    "This is how it came to be. And now I can finally show you." I say to...myself? "Error, there is no time for this!" Ink screams at me. It's weird being able to see yourself from a different point of view. It's weird to have your bodies swapped with your archenemy. But there is more to just a simple switch of bodies here. With twisted dreams of the future and out of place emotions, I can't help but realize something that shakes me to the bones. That there is something or....someone hiding in the dark. Behind the stage, they cast the cues. Writing the script. And setting up pawns, just to watch them fall on their own playing field. Someone else is pulling the strings..........
