    5 years. 5 years it's been. 5 years since Frisk freed the monsters. 5 years since your mom left you. 5 years you've put up with your father. 5 years of suffering and anguish 5 years of torture and abuse, mentally and physically. But that was gonna be stopped. ~~~~~~~~~~~~~ Meet (Y/N), a abused runaway with an attitude that's bound to make some people pissed. Well, that's kind of an understatement. After her mom leaving and being beat by her dad, she decides to run away, and finds a completely different world. One that makes her struggle to survive. How could she possibly make it? ~~~~~~~~~~~~ Meet sans, the laid back, lazy, and funny skeleton monster from the underground. At least, that's what he used to be. Now, he's known as Gaster Sans. He's still funny, but in a different way. All the laziness is gone. He's charming, clever, and quick. Ever since he combined souls with Gaster, his personality and appearance completely change. Will he ever feel the same, normal, again?

    Geno is the Captain of one of the most feared pirate crew in the seven seas along side his Quartermaster, or first mate as some call him, Error and Fresh, the Master gunner. While from the first look Geno looks fragile and unfit to lead a crew, he's actually cunning, smart, reliable and skilled in fighting both with swords and pistols. He always kept his word an put his crew first, always listening to their worries and suggestions. Most decisions where decided via vote. While his judgment was always fair and accurate, so where his punishments and no one was able to get away from one if done something wrong. No one was able to hide anything from the captain, he knew a lie when he saw one. Reaper is a siren shunned by his own people for being "too dangerous". I mean it's not his fault that he was born the way he is. And those few deaths where accidents! Yet even if he tried to explain and redeem himself, he was still exiled and every siren or mermaid he meets never come closer, only further away. And so he wonders the seas by himself, doomed to be alone for the rest of his existence. Or is he? [This is inspired by a song "Siren" by Kailee Morgue and I really wanted to write it before I forgot about this Idea.]

    Book majority written in English, I don't tend to update this daily or with a specific schedule, I just write things here when I really want, need or have any other ideas. I also don't put trigger warnings so you wanna be careful around here. Thankfully, my titles aren't baits, I'm not gonna trick you with a funny title for a depressed story. It is what it says, and I hope it's not gonna bring much problems. Thanks for reading and checking this out, take care 💜

    (This au along with the characters appearance's in this au is created by me) [Frisk decides to end their run very differently than how they usually do..though when they left the underground..the story didn't reset and the player didn't follow their every move anymore...now with no player, the universe decided to change drastically...changing the characters looks, backstories, and memories..this change was made to fit the new upcoming player..though..despite everyone else changing along with their memories...there was one who still remembered the original universe..] (The year for Undertale is uncertain and there's people that say it takes place in 2090- but that is a lil too far- so I chose 2024 for the year of this story)

    Ink becomes a child....yea! and Error & friends are forced to take care of him... Some of you would recognize this fic from a oneshot I wrote a while ago. Well I decided that I liked it enough to spin it as an actual story, rewriting the original oneshot and expanding upon it :) This Story is meant to be an Errorink fanfic, because I am the #1 Errorink fan, if there are no fans then I am DEAD. Anyways...book cover is mine (lmao)

    This is an Undertale AU I originally planned on making back in 2019 but, I wasn't capable of making all the character designs and forgot about it for two years. A few months ago, I thought about redrawing the only two designs and reviving it as well as changing most of the original plot and instead of making a comic series, I'm writing it so it will be easier to think about more designs. OCs are included in this AU. If you would like yours to make an appearance, message, or tag me to discuss when they can appear. This is season 1 of the series and it will basically follow the events of Undertale because there was a strange, unexpected reset after 10 years of living on the surface. Now, it's up to Frisk to help her friends remember their lives before the reset and save the world before Flowey tries to kill all of humanity as well as monsterkind and Mystickind. Can the determined human survive yet another perilous journey through the Underground or will everyone fall to Flowey's hands (leaves?)?

    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)

    [Yes I used to have an undertale au roleplay book, but I deleted it once my hyperfixation died down- but it came back recently after a friend started talking about a book they were making that had Undertale au's involved- and that soon reminded me of my own undertale fanmade au book I was making but ended up never working on it- so due to me being reminded of that, the urge to rp Undertale au's came back as well-] - (note: this book will not be of just sans from different au's, other characters will be involved as well. The original au aka just Undertale will also be involved in this book.) - (another note: I don't know every single au, so there will be au's that I'll miss, and the au's that will be in this book will be the au's that I know the most(though my knowledge on the au's might be a little rusty, I still know basic knowledge about it) (The pictures used in this rp book is not made by me and is found on Pinterest or on google, the only pictures that are made by me are of my oc's appearance.)

    Monsters have never been sent to the underground. The war that raged between monsters and humans ended in a draw, but no peace treaty leaving relations tense on both sides. The earth and cities are not in the best of shape after such a war, the weather tending to vary greatly from area to area based on residual magic left behind from the fighting. Some areas are human territory, others claimed by monsters, some simply neutral with a hope of peace and calm. Thieves and bandits are everywhere, the royal guard and police force not able to keep up with their growing numbers and largely leaving them alone at this point. Technology continues to advance, with each race constantly trying to outdo the other. Jade lives and fends for herself, currently living in an abandoned warehouse near the Hotland district, in the more desert and neutral areas between there and the human city of Külaküla. What happens though when she stumbles upon an interesting sword leading to long journey? - - - - - DISCLAIMER: I do not own Undertale or Transistor. This is a fanmade story that will have elements from both but will follow the story and head canons I accept or want to use for the sake of this particular story-line. This story will have influence from Undertale, Echotale, Transistor, and my own au Tomadachitale. You don't need to have information of them all before beginning, I'' be doing my best to explain everything at some point in the story and you can comment questions you may have about it! Plus, I'll be adding some of my own spins anyway. Thank you :3
