    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

    Being part of a group dedicated to helping protect AUs against harm can take a toll on someone, specially if that someone is insignificant to his teammates. The self deprecation, and self doubt, can make the worrier feel unuseful to his team. And with the importance of the job it could make this regular mortal long for their old, simple life. Will Swap overcome his uncertainty of being a star sans and continue to help save AUs from those who seek to cause harm to them? Or will he resign his position and go back to being the 'regular' sans in his AU? (Art by Jael Peñaloza (Jakeiartwork on YT)

    Y/N L/N was 25 when they died, and they were poisoned. WARNING - bad grammar, bad spelling, bad plot, cursing, and a bad death scene there might be some Reader x Sans AUs in this but I'm bad at writing romance so it might just be a lot of fluff instead. it will take time for chapters to come out

    Oneshots that are a mix of xReader and ships. I usually do popular undertale ships but if you want me do do a different ship or xReader just put it in the comments. There might be some smut (not a lot, just hints of it) but I'll warn you ahead of that so it's not a surprise. There could also be self harm and gore and death so I'll warn you of that too. ... ENJOY!

    We all know Undertale and it's infamous AU's. The favorites and the...others...let's just say this is a new beginning. For all of them. Or as many as is decided to be put into this story. Who knows what will happen. This story is for shits and giggles, I will try to keep the characters Canon but they will have some aspects that are to help with the plot from going haywire. All original characters belong to their rightful owners. If you have any questions or ideas would would maybe like to see happen please feel free to comment. And if you don't like undertale or the AU's...then why are you here?

    This is my favourite ship, and it isn't represented very much here. Sometimes, I don't know what to write and just come up with a bunch of oneshots. So now I combined those two things and made this. Enjoy? (The picture in the cover isn't mine, by the way) The titles of the chapters in this book may or may not be all inside jokes-

    This is an Error Sans x Outer Sans ship story. If you don't like that then get off my page. This story contains sexual scenes and crude language. Sexual scenes will be marked with 🍋 at the chapter name. The rest of the chapters should be fine. I'm bad at writing so excuse any errors in the writing (ba dum tiss) Also I'm sorry the chapters are so short, they look a lot longer on paper. Cover Art by Me
