"Well well well, look what we have here." Cover by: @ scryl.studio on Instagram

-This story is also on my Quotev and Amino!- Dream X Error. Ink and Error make a truce, but because of that the voices in our glitchy's head become mad. What happens when Dream finds him having a moment in the anti-void? Cover picture not mine~

I made this book for @KawiiPotao6678 they have never read a flowerfell x reader so I made this book for them. But all you other people can enjoy as well. Sorry if some of the information on here is wrong I am not very familiar with the Flowerfell AU. I will look up what I can and learn more about it while making it. I will also fix what mistakes I have made because some people are so picky about spelling (not saying any names). I own nothing but the story!!!!!!!! I don't own you!!!!!!!!! I don't own undertale!!!!!!!!! I don't own Flowerfell!!!!!!!!!!! Nothing is mine!!!!!!!!!!!!!

The Prince of darkness got rid of terrible nightmare that he had for many years. Long-forgotten feelings returned to him and he realized his purpose in life.

Dream shows up at the front gate of Nightmare's castle, hurt, scared and alone...waiting for someone, anyone even if they hate him, to help him. This was the only place he knew where to go, he couldn't go back to the stars Sanses base,especially after he and Ink just had a fight, and he left. He was bruised, bleeding, alone, terrified...he needed help...luckily for him there was someone there. Cross. He never talked to him well at least not officially without fighting...Cross walked to the door thinking it was someone else and was ready to scream at them until...he saw him...the guardian of hopes and dreams, Nightmare's brother, Dream hurt scared and alone...Dream mumbled something. "...sorry...heh had no where else...to...go-" he was barely able to finish the sentence before collapsing into Cross' arms. The soldier stood there dumbfounded on what to do next... Warning ⚠️ this story contains some themes not suitable for young children and will have some themes talking about sex, sexual jokes, gore ext.

Clover doesn't give up his soul because justice still needs to be delivered. The Wild East, and later practically the entire Dunes, declares independence. They declare that any human within their borders is under their protection. Civil War looms over the Underground. Would you like to see what happens? Note: This is NOT a story. This is an archive containing information about my AU, Desert Sanctuary. I might write a proper story in the future, but for now, this is where you can read about the narrative, the characters and how this massive change affects Frisk's journey. Fanart and other fan works based on Desert Sanctuary are welcome and encouraged

What if there was an anomaly in the Underground? No, not Frisk. Not Chara either. Someone else entirely. How could a few measly children stand to this supposedly immortal foe and save the Underground from destruction? Is it even possible to do so? Only one way to tell... ~o0o~ Disclaimers before you start! •There is NO fanon ships. That means no Soriel, Papyton, etc. The only ships are Torgore (in the past) and Alphyne. •This is NOT an x reader. I dislike those types of stories. The reader will have no part in this, and they will not be shipped with anyone. •This exists outside of canon to an extreme. For example, Frisk is the second human and not the eighth. •There will be OCs, but only for a few humans and they still technically exist in normal Undertale. •There is a sequel. I'm planning on rewriting it after this one, as it is much more random and definitely needs it. Clanky, plot holes/retconning, etc. It's more of an OC thing, to explore them and their issues, than an Undertale thing, but it has its similarities. •There will be some explicitives. It won't be unnecessary or excessive, only when it fits the situation and character. I will not be using any slurs, as that's just plain disrespectful, even if some of them apply to me. Credits: Undertale, obviously, created by Toby Fox and Temmie Chang. "The Time Before" by ANinnyMouse42 is the backstory for Sans in this AU with some adjustments (mainly since that was very close to my original idea before I read it and I don't want people to think I copied their masterpiece or smth, if you haven't read it please do so, it's really good). Some things will be in reference to the other books in the trilogy or "From War to Science" by Emotistic-optimistic. If you haven't, read that too. It's really good (along with its sequel). The cover was made by me! Have a good day! (Also, the title is a placeholder, if anyone has any ideas that make more sense, please let me know.)

Taking requests, basically always. Just know I am absolutely horrible at finishing them. Includes fandoms I'm in such as: Hollow Knight OMORI The Owl House Cookie Run A few others I've only written one for. THERE IS NO SMUT IN THIS. I WILL NOT WRITE SMUT IF YOU REQUEST IT.

Sans au One-Shot, and also including my own aus that I had made too ... Plus Clover too as of 12/23/25

Hello! In honor of Underverse 0.8 part 1 coming out and Jakei's year and a half hiatus, I am going to (try to) do this thing I will be calling "Weekly Underverse" where I update weekly with some sort of Underverse related content. It's not going to be anything big. Some weeks it will be a 3,000 word Cross fic, maybe a digital drawing I worked on for 5 hours. Other weeks might be as small as a snippet of a poem that was inspired by an Underverse thing, or a little doodle I did in my notes packet. It may even be recycled content I have posted outside of this project. But whatever it is, I will try to update it weekly until the hiatus is over. Weekly Underverse starts today, November 20, 2024. Updates will (try to) be every Wednesday. Underverse belongs to: Jael Peñaloza Little note: I am nowhere near an Underverse expert, so most things might be fanon, most things might be Cross focused, but maybe I'll do some learning and write with the other characters. Maybe I'll give fun facts one week. We've got about 78 chances so... we'll see where this goes!

in which - killer is loyal to nightmare. but perhaps, too loyal?

Everyone knows the tale of the Monsters; A long time ago, the Monsters and Humans reigned over the Earth in peace, but then war broke out and the Monsters were sealed Underground. From there 7 Humans fell, the first human was adopted by the King and Queen of the Monsters, but they died and their son was killed by the Humans on the surface. After that, the King declared war on the Humans once again and planned to break the Barrier using the Power of six Human Souls. This is the story we all know and might love, but this story is different. This is the story of a new Soul, one that hasn't been seen before, the Soul of Nexus.

This fanfiction is SUPPOSED to be written FOR FUN. Most of my fanfictions are usually me putting my writing skills up to the test. However, this one is a bit... Different. No explain.

Soul Linkage is a Regretevator x UnderTale AU where our main character, PLAYER, tries to find the portal back to the real world after shifting to REGRETEVATOR due to a dare from their friends. Will they spare their enemies? Or will their demise be met at the hands of another shifter? Read it and find out for yourself. CHAPTERS COMPLETED: 15 / 15 "Soul Linkage" aims to give readers who had played through UNDERTALE the same feeling they got from when they played it for the first time again while also adding some flair to the original story NOTE: NOT EVERY CHARACTER'S PERSONALITY WILL BE 100% ACCURATE TO THEIR ORIGINAL COUNTERPART, THIS IS TO MAKE WRITING IT MORE FUN AND MAKE IT MORE INTERESTING START - 7/20/2024 END - 9/29/2024

Danger have awakened from the darkness, the DragonLord awakened from his slumber after a cast from the Surpreme Being to put his scheme into sleep. Now that he has awoken, he will make sure no one stand in his way to reach his once glory for his decreased father, and you, the reader, shall stop him from reaching his ambition.

Cover not mine!! They have known each other for a long time. They have hated each other for as long too. They fought often, they each lost and won an equal amount of times. It was a routine of theirs. Destroying Alternate Universe, fixing them, destroy, fix, again and again. There seems to be no stop. No one would dare to get in their way, no one dared to help nor did any others tried to reason with them. Until this story... I will make a better ending one day, but for now I'm kind of out of ideas for this story :/

The Joku Brothers, Dream and Nightmare, in which one of them are soon-to-be king. Dream gets a new personal bodyguard because he simply can't stay in the palace, while Nightmare finds himself being trained for war by a soldier...
