💫 What if you woke up inside the body of a guardian of light... whose soul isn't entirely yours? Dream Sans was supposed to be the eternal protector of positivity, the last hope against his corrupted brother, Nightmare. But after centuries of imprisonment, something went wrong. When he finally awakens, his body isn't his alone anymore. An ordinary soul from another world has accidentally possessed him. Confused and overwhelmed by strange powers-healing, empathy, teleportation-they must navigate a realm where every smile hides a wound, and every shadow whispers temptation. As allies and enemies clash-Ink, CORE!Frisk, Neil, and even Lanny, the reluctant mentor-the possessed Dream must decide: Will they embrace their borrowed light, or give in to the sorrow that has consumed Nightmare? ⚖️ In this path of neutrality, the line between good and evil blurs. Only balance may save existence. But balance comes at a cost... 💫12 chapters 💫1000 words per chapter

A 20 year old woman/man fresh out of college. (Y/N) (L/N) works at home and mostly writes tons of books and novels that arranges from different genres that caught many readers' eyes, lets just say they got pretty famous for their books that allowed them to live a comfortable (Very rich, don't ask) life. Enough of that though, one day something bonked them on the head that ended up leading towards the attic. What mysteries could they have ended up in when met with a glowing object in the corner surrounded by multicolored boxes? First story, ALL of the pictures that end up in brutally trapped this fan-fiction will not belong to me. I am pretty confident that there will be many grammar mistakes in the following (developing) story. No worries though I will try to find the time to correct those mistakes. There will not be any smut, sorry I cannot make it even if my life depended on it XP. THOUGHHHHHHHH because our friend Lust is in this story, there will be a LOTTTTTTTTTTTT of inappropriate flirting, sorry. Including a few uncomfortable situations-👹 (Y/N) will be a bit socially awkward, though also will have a bit of an ambivert- ish personality I guess- This takes place in a time where the star and bad sanses made a truce. I AM SORRY IF IT TAKES ME A WHILE TO POST!!! I AM SORRY IF I MAKE CRINGY SCENES!! Sooooooo let's get this dunnn X)))✨

You were an average kid, somewhat having a older mind than most of your classmates. you had always been into the undertale fandom, and even knew almost everything about the aus and soul colors. while what seemed like a normal day at school quickly turned around after a huge bang struck the class room next door. in this story y/n is nonbinary and 12-16 years old. But more interpreted as 14 I post a new chapter every 3 day and 5 days at the maximum. WARNING: this story will mention some forms of slight emotional harm. And Sexual abuse. Readers be safe. Please if you are in any danger, contact someone. You are not alone. With that aside enjoy the story . This story is finished as of September 1 2022, I encourage you to read my other story "Our Disturbing Love" And in the next month or couple weeks I plan on creating another bad sanses x reader.

You have faced a rough life, abused and neglected. But one day, at the age of eight, you are nearly killed by your own father, and find yourself in an empty white Void, where two strange skeleton-like beings named Ink and Dream discover you. When you awake, you convince yourself it was all a dream. That is, until ten years later, two years after the monsters were released in your world, you find yourself nearly killed once more, and awake in that world once more with the same two beings. Only, this time, you don't wake up. You become trapped in the his world with these beings, and soon discover the many other versions of them--from a glitch hellbent on destroying all the other 'AUs' in the universe to a virus--to other strange, alternate unvierse-travelling 'Sanses.' As you try to find out why you, a simple human, have been allowed into this wild world, you discover that your purpose is much more than you could ever imagine; along with love, friendship, romance, and your true self all related to one thing: the world of UNDERTALE, and the true purpose of the SOUL.
