    You wake up, finding yourself standing in a desolate grassy field, only the green grass had withered and died, leaving behind a dry, lifeless expanse. Above, the sky was a haunting shade of dark crimson, with a single crescent moon hanging in the air, its soft glow covered by the misty clouds. An overwhelming sense of pain consumed you...what happened here...? Let's rewind! You are Y/n, a human living on the surface, where monsters and the 'underground' don't and never existed. It was known as 'Undertale', a game made by game developer Toby Fox. You've played it before and loved it very much. The game became popular over time, and people started making alternate universes (au's) of the game such as Underswap, Underfell, Horrortale, Underverse, and many more. You had your favorites, mostly the more popular ones, and you knew the stories behind them. Little did you know that something unexpected would happen, changing your life forever. Cliché, I know :/ . .. ... .... This story has been inspired by some other reincarnation fanfics like "Misery Loves Company" by Fanfic_yes, "Reborn as Error" by Kiwi_Seal, and "Wait... I'm Nightmare!? I Thought I Died!?" by Donut2460. I encourage yall to check those ones out! They are great :DD | | | | (Cover art doesn't belong to me. I found it on Pinterest. I only edited it: https://www.pinterest.com/pin/10555380369605142/)

    TW: Swearing and slight gore Y/N reincarnates in the anti-void as a Voice... Will he befriend error or will they make them hate their guts? And will they meet other people? Only time will tell. Hello, this is going to be my first book and idk if it's going to be good so meh :v This story was inspired by transported as a voice by Virus_bOi, I obviously do not own undertale and I don't keep up that much with the fandom, so some personalities might be different, but hey. I can just say that it's a different multiverse ¦ ] The cover image is from Shira Wolfiecute on tumblr

    Dream gave Ink a mission, and Ink gladly took it, but on his way to his mission, he made a small mistake. He was not expecting the unexpected. Now he was somewhere new, familiar but unfamiliar faces everywhere, a skeleton with the same name as him, but more cheeky and bubbly. | No images are mine. | No character present here is mine. | I don't own anything but the storyline. | Sorry for any grammar mistakes in advance. English is not my first language. | I suck at this, so be gentle with me. I have feelings. | I do this for fun, I might take a long time to update this story, or I might take some hours. | I can give up on this story from day to night just because I want to. I hope you enjoy it

    Stanford thought he'd never be surprised again, especially after all he'd encountered across the multiverse. He was proved wrong when he first met (Y/N). **************************************************************************************************** Stanford Pines is a very cautious man. He's never really trusted anyone since he was pushed into the portal by his brother, Stanley, a year ago. That was flipped on his head after he met (Y/N). He's starting to wonder where his sanity went, and if he can beg it to come back. When walking through the world of Dimension Manless (a world where all humans randomly disappeared. Ford did not want to learn what wiped them all out...), he found a beautiful necklace on the forest floor. This necklace turns out to be sentient, a being capable of granting protection to whoever wears them! When Ford tells the necklace he's trying to find the portal to the next universe, (Y/N) tells him that they just happen to know the way! (Y/N) stays wrapped around Ford's neck as they give him directions to the next portal! When they find it, Ford is about to place (Y/N) down and leave when the necklace begs to come with him. After a bit of reluctance on Ford's part, the two set out on a journey together! (Y/N) is a very cheery person. They themself do not remember their origin. What they do know is that they were made by someone powerful. When worn, they and whoever their wearer is are protected by magic force fields incapable of being destroyed! They can't wait to help Ford on their adventure!! **************************************************************************************************** Join this unlikely pair as they travel across the universe, going from Yu-Gi-Oh, to The Owl House, and so many of your favorite media! (Updates almost always every Friday!) (I feel like this is obvious, but none of these characters *except* Y/N are mine. Thank you for taking the time to read this!)

    Nightmare was the guardian of negativity along with his brother who was the guardian of positivity, who is named Dream. Nightmare protects the negativity side of the tree of feelings and Dream protects the positive side of the tree. Nightmare was hated for being the guardian of negativity - the same as his backstory - so after years of bullying he had finally had enough. He grew jealous of Dream and decided to 'give up' by eating his own apples, causing him to corrupt the tree and make them completely negative. Nightmare got corrupt by the apples and that painfully destroyed himself, until only hints shown through his left eye. The eye that was covered by the corruption. 'Nightmare' turns Dream into stone and he kills his bullies. He cuts the tree of feelings to the ground and looks around. *cool movie fade out* Sans au's story. Hints of killmare and some bits of Errorink. Trying to be as angsty as possible. Creator of this story: me! (Dark_moon983) Not canon! Not anywhere close to Canon!!!

    From the beginning of time, every little thing had a story. You, your family, friends, your pets, plants.. even the most inanimate of objects. They all have a story. But, have you ever entertained the thought that your universe had a story to it too? That there was something more to this world than you thought? Stories of alternate timelines and alternate universes all existing at once? Well.. allow me to amuse that thought as I tell you the story of the fabled, Undertale Multiverse. You all know about Undertale.. the original. The one that started it all. And you have heard of the order that it's alternate stories arrived. The first two alternate universes being UnderFell and UnderSwap. That may be the truth, but the story is much more complicated than that.
