    Okay so imagine all children from other people's undertale AU's attended a certain school in the void after a virus destroys their homes. Imagine the void had things like nature, houses, weather, water, stars, sun light, and moon light in a certain large part of the void. Then imagine I wrote a story about this Idea. Good. Cause that's what this book is about. I don't own any character except for my OC's. The rest belong to their original owners.

    (Y/N) (L/N) was just like any other normal girl(or human to be exact), with the exception that she wasn't really supposed to fall down Mt. Ebott. . . All she could remember were memories of things that were long since forgotten and some quite possibly deleted. She too was supposed to be deleted alongside those memories, though because of some unknown reason, she never was and instead, was sent to a place where nobody even knew existed. . . What happens when a certain Artistic and Forgetful Skeleton stumbles upon an old doodle of code of a person that "never" existed?, and after some thorough thinking and decision making, decides to create that person?. . . The moment his pinpricks set eyes on the person he had just "revived". . . Something tells him that things were gonna get very interesting. . . (Note: Cover Image ain't mine, though I totally didn't go to Google-Chan and typed AU Sanses for the picture hehe... oof-)

    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.

    First book sry for mistakes. Nothings been the same since the death blast. That what they started calling the "incident". Somewon pressed a button and nuclear bombs appeared in every au and went off at once leaving a toxic radioactive wasteland. This who survived mutated from radiation and those that didn't mutate lost there magic from radiation, no one can summon portals anymore. Error is one of the few who didn't mutate but his magic is basically gone. His blasters are full of radiation and will self destruct an explosion of radioactive waste (and an actual explosion) after a few seconds of being summoned. Teleporting to much will give him radioactive poisoning and he can only summon bones in his hands and even then not many. Error practiced summoning bone tools which helped him a lot when he needed better defense and weapons/tools. But we are not here to talk about what happened shortly after the death blast that's for another time. For now we are focusing on current events. This multiverse is one with a balance and error as destroyer (he hates his job but wasn't forced) but since there's no more aus being made balance does not matter.

    what if, Error was actually just a tall 14 year old? what if errors soul was slowly and painfully deteriorating? what if he doesn't destroy because he can or because he was forced to? what if he doesn't just destroy AUs but he takes there code to fix his soul? cover by me (sorry if its hard to see) idea by me? i dont think anyone else has made a book like this. FGOD concept by Harrish6 Art by me NOTE: the ship CorexError has been removed from this book due to the fact I don't know how I'd bring that in 👀 many apologies!

    Alphys always knew there was something else out there. This couldn't be it. She studied all of the sciences she could, and came to one conclusion: The multiverse had to be real. If it wasn't, then she didn't know what to think about existence. She just had to prove it. But how?

    [[Undertale and Stardew Valley AU = StardewTale This is a OC insert story.]] The Undertale crew make it out with the help of Frisk, the forgiving eight year old girl. Little do they know, that their lazy days are over. Curt, the forever smiling and optimistic seventeen year old is the exact picture of joy. He meets Toriel and Frisk when they first arrived in Stardew Valley with nothing but open arms and a guide through the town. And come to love the little farm valley. Everything is peaceful. W H A T L I E S After the ruby eyed demon stumbles their way to the Valley, Curt becomes possessed and is forced to murder everyone with his family heirloom axe. A blue skeleton, unable to hurt the honest, optimistic, human crying in front of him as they battle, is killed close to last, trying to protect Frisk. The child is the last to go, and in the worst condition. Curt is let go of by the demon Chara, bloodied and filled with GUILT. He wants to avenge his friends and family, but finds he has too much FORGIVENESS. He is killed in the end too, but finds he can RESET. (this story is dead, and really old, lol~ kinda cringe, but fun at the time.) #stillhuman #avenging #SOUL=Forgiveness #lightgreensoul #saveChara #IOwnStardewTaleAU
