Undertale
This is an Undertale Multiverse/Underverse/etc thingy, focusing on one of my favorite OC's, Slate. (if you know me already you mightve seen him/read about him before.) -------- In the dark eerie structure known as Nightmares castle, starting at a horribly young age to be dealing with said goopy skeleton, Slate was raised with the idea that he NEEDED to obey Nightmares every word and feel immense guilt when he failed him, despite Horrors best efforts to tamper with this "training" Nightmare harshly forced onto his son, Slate still ended up completely loyal to Nightmare like some kind of dog. But the intrusions of other influences made him start to question if he has been laying himself in a pile of thorny black roses, when a fresh patch of soft, fragrant, colorful, and frankly unknown flowers were just on the other side of the bush. -------- Slate is a shipchild of Horror Sans and Wyvern Sans (another OC), well- one of them, he has 2 other siblings, Krysta and Obelisk. Krysta is his twin sister (non identical), and Obelisk is their younger sibling. all 3 reside in the same place, but all 3 were also exposed to different things growing up, because Nightmare wanted to experiment, incase something like them ever were to happen again. this story is mostly for my own entertainment but im posting it publicly because it just feels better doing that instead of just writing it somewhere only i can read it at.

For some reason, Ink, the Creator and Protector of the Sans AUs, has decided that some of the Sanses of the Multiverse should go to highschool again. Honestly, no one really liked the idea, especially the Bad Sanses, including Ink's enemy, Error. Prince Nightmare is one of the AUs that must repeat these years of treachery. He basically only finished his actual highschool, and is NOT looking forward to having to do it again. Luckily his brother, Prince Dream, will be coming along the journey beside him. But Nightmare and Dream Are polar opposites, so Nightmare can't really get along with his brother's friends, nor Dream get along with Nightmare's, if he had any. With rules to follow and secrets to keep, Nightmare must go through highschool and not let slip the terrible things that happen at home. But then suddenly the two princes disappear. There's no trace as to who might've taken them, either. The only one that doesn't seem concerned is their own father, the king. King Sun-Beam. What is he hiding underneath all of those jewels and fake smiles? A/N: There is lemon/smut. So all you innocent people out there-- don't worry! Because I warn you at every chapter, and right before it happens. I designed the cover, but did the not the amazing artwork of Nightmare Sans. So credit goes to that person for the art. :D Update!!!!: This story is being rewitten. I'm making another book that'll just be this one but a little different. Once that's posted, I'll make another "chapter" in this one, giving a link to the rewrite. Thank you to everyone who still reads or checks up on this book. <3333
