He killed them all. Dust, down the waters of the the forest it runs, through the veins of the skeletons and the demons that prowl the night. It's the silent enemy, the adversary that slowly chokes and brings down entire armies to their knees. None can oppose it for none have the will or the strength. And it is the dust that emerges from the mouth of a mountain that overlooks a city, the dust that creeps and crawls through the forest and down the alleyways. It is the dust that wraps its bony hands around the throats of the damned ignorant enough to walk the streets, squeezing until the last heartbeat thrums. You are a detective in this city, a quaint area with little crime and a police force hopped up on Dunkin Donuts. But when a string of murders plagues the town, you are thrown on the case following cold leads and an ominous trail of dust. But one night, when you catch wind of a scream and follow it through the dark, you find a skeleton and the rest is history.

"..Do you think even the worst person can change..?" (Y/n) one day got into a terrible accident, gaining some sort of weird "amnesia" of some sort. She remembers things perfectly clear. But for some reason... she doesn't remember the crash, or what caused the crash. This got her into buying a small "pet" called a bitty. The bitty she got was very weird, it just hated every part of her existence. For what reason? What does he see in her that she doesn't?.. Go through this adventure, you could call it, with yourself and others! But remember this will get pretty weird and confusing.... But if you like good story's, run for it!!! ('Good story's?' Bruh, no this is cringey! I mean if you want to read it???) ~Mbaird422 ALL ART OR VIDEOS DOES NOT BELONG TO ME, And if it does i WILL remind you Undertale, bitty's, and DustTale belong to there rightful owners, this is just fan fiction, please Do not steal book or idea, and as well characters too. Thank you and enjoy reading. ☺️ ^art for the cover is not mine! (It's actually piece of a comic!)

100 years after the tragic events of Dreamtale, the two brothers continue a war of hate and love. Any AU unfortunate enough to get in the way of the darker brother's path is either conquered or destroyed. Your universe, Recoveryswap, just so happens to be in the most recent crossfire. But with your personality and luck, you may just find yourself on the path you've always wanted. A path of violence, a path of excitement. And who knows. You might be the saving grace for a fallen prince. (It is highly recommended that you read 'Dreamtale: Origins' before this book.) [All characters belong to their respective creators. I am only the creator of Recoverytale/swap.] -Cover Art by Unknown- Book 2 of the Dreamtale Trilogy

Routine. The entirety of every living thing is dominated by it, human or monster. Everything HAS to be the same. It was in this that you were the exception. For you everything was new, every time line a detailed altered in order to satisfy your sadistic desire for a new ending, whether it be only a few details of dialogue altered or something else entirely. Monsters you once considered family you now butcher and slaughter without a second thought, after all, that's what the Reset is there for, right? And all at once it stops. Your small hold over the Underground is ripped away from you and you are thrown into a dying timeline, monsterkind's final attempt at self-preservation. You're alone, completely and utterly alone. Except one. And he has a bone to pick with you.

[ Sans AUs x Reader ] This wasn't what you expected - this isn't what you wanted. You wanted to rest, to finally, finally breathe, relax. But apparently life had other plans for your sleep deprived self. It wanted to trap you, it wanted to make you see - to make you realize, you're life isn't what it seems to be. You didn't want to take part in this chase - in this game. This isn't what you wanted. But this is what you needed. And some skeletons are here to join you for the wacky ride. I do not own Undertale, Toby fox does. I do not own any AU's in this story unless stated otherwise. I only own the plot of story.

Will he be planning something by kidnapping the one with the dawn tones? After all ... he was the only one who made him feel healthy, he knew it was because of his aura, but ... it would be his personal drug against his madness and inner pain after what he was forced to do in his world. What will the dreamer think?
