When a demon summoning goes wrong, a rich and powerful man's son gets killed and (Y/n) is forced to team up with the Demon King that did it to survive the ensuing attempts on her and her family's lives. But the King will only do it on one condition: he gets her soul. So with no choice but to die for her mistake, His Summoner promises him her soul when the job is done. | 

- Demon! Nightmare Sans x Female Reader 
- A little bit of a reverse harem with plenty of Bad Sanses x Reader moments (with a canon reason for it :D), but ultimately, (Y/n) is Nightmare's 
- Honestly you could read this with no prior knowledge of any of the characters and you'd be just fine 
- Kinda a slow burn? But don't worry, I throw in so many subtle/not-so-subtle intimate moments with all the Sanses that it makes it worth the wait :D 
- I'll throw in some bonus chapters with the other Sanses for extra (non-canon) fluff that doubles as a breather from the story, too 
- Is the relationship toxic? Maybe. I mean, this is canon Nightmare after all. But that's the beauty of a fictional story, no? 
- A lot of the symbolism and hidden meanings aren't obvious, so you might have to be on the lookout to see them (and keep in mind: Night doesn't openly show many emotions, so the devil is in the details) 
- I'm not going to spoil anything, but for all you anxious readers out there like me, I'll divulge I'm a sucker for happy endings *wink* 
- It's my interpretation of the characters (kept as canon as possible)

Expectations and a Golden Stitch-A DreamError/Insomnia Fanfic by HappyWriter62
50 parts Complete
Dream always felt the weight of expectations on his shoulders and they've only grown worse now that he's a Star Sans. Save this AU, rescue that person, stop Nightmare over there, and make X person smile! It's a never-ending cycle of tasks and he gets asked more about why he hasn't done it sooner or defeated his brother yet than thanked for what he accomplished. He feels trapped in this position and doubts if he didn't have his positive aura that anyone would care for him. Most like him for the joy he brings or what he can give them. Nobody around him ever feels genuine without a doubt in his head. Add in the stress of protecting one Star Sans(Swap) and keeping the other(Ink) from starting trouble and you have a positive guardian ready to break under expectations. Then you have Error, the destroyer of AUs. His reputation speaks for himself and builds all the expectations he needs whenever he steps foot into another AU. He's as bad an omen as a black cat crossing your path. Others assume he is bad because of his "freakish" or glitching appearance. He has accepted these but it gets tiring when he already has the voices bossing him around or Fate reminding him that he should do more destruction. But he doesn't limit himself to destruction. He watches UnderNovela, admires the stars, and appreciates what he can. He pushes the limits of what is expected of him or disregards them completely. A trait that Dream eventually finds himself admiring in him, the known enemy of his friend. He knows that Error's feelings are genuine since he doesn't change in his presence(still an angry manchild). So when Dream gets wounded and stuck with Error on a whim, where will it take them? Will it be a mistake remaining in a hatred of enemies or will it change them both for the better? Could this admiration open Error up to corrupting Dream or will he be the influence Dream needs to against expectations and live for himself?

Warrior Cats x Undertale Multiverse Crossover ~~~~~~~~ Since the Multiverse was created, the Creators have been fighting over the AUs non-stop. It was a horrible, bloody war that lasted centuries. Many were killed and many were cast away as outsiders. One day, the Creators met in an AU called Dreamtale, and after another battle, the dead came down from the sky as spirits, and the fighting ceases. They told the Creators that were alive to unite, or they would die. So that's what the Creators did. They united. They- and their AUs inhabitants- created Clans. They all lived in Dreamtale, surrounding the Tree of Feelings. Generations passed and the Clans had never seen a war so horrible since the War of the Multiverse. They lived in an almost-harmony. Until Nightmare came along, that is. ~~~~~~~~ Hiya! It's me, Sighnerd. This idea came to me in a dream, so I'm making it a reality. I love Warrior Cats, and I love Undertale, and I tried once before to merge the two, only that didn't work because I wasn't as experienced in writing as I am now. You don't need to understand Warriors to read this! It'll all be explained. The only similarities are the fact that the Sanses (and some not-Sanses) live in Clans, follow the Warrior Code (which will be explained in the introduction), they aren't cats (that's just weird), they have the same roles (tweaked a little because they aren't cats), they follow the same customs, and some other small similarities. Kind of a slow burn. That's what I'm going for, anyway. There may be a few toxic moments, but it's Nightmare, so it's fine. Right? Art and characters (except for the Empathverse Sanses and Sigh) do not belong to me! Neither does Warrior Cats. Cover art belongs to ProductionRoxy. :D My interpretation of the characters, but I'm keeping it as canon as possible. They're tweaked a little to match the Warriors setting.

[[THIS STORY HAS MENTIONS OF SUICIDE, SELF HARM, AND SEXUAL ABUSE.]] Y/N grew up a normal child. She had normal parents, an annoying younger brother, and good friends. Life was good to her. She wasn't a straight A student, but she got decent grades and was relatively smart. Until she moved out of her parents' house, confident she could take care of herself, by herself. She got a small house in a small neighborhood in Starlight Springs, Colorado, and for the first three months of living there, with a decent job, she was relatively happy. She was an artist as a hobby; people would sometimes commission her online, and she'd make a little extra money. However, three months after she gets her job, she ends up getting fired. Her rent increases around that time, and things go downhill. She calls up an old friend of hers from ninth grade, and she settles in as Y/N's roommate. She was nice at first, until she started getting nosey. She wanted to know where Y/N was at all times, what she was doing, or who she was talking to. Y/N was getting sick of her, but she didn't think she could kick her roommate out without losing the house, so she endured her suffering, continuing to look for a job and draw. One day, she posted one of her art pieces on a Discord server, looking for people to commission her, and in the process, she met a certain man named Fell. --- HIYA! IT'S ME! Sighnerd :D I know, I know, I was gonna make Eradication, but I decided this would be better :3 (Gosh I hope it is). COVER ART IS MINE! HI HELLO I DREW IT :DDD I do not own any of the characters in this book! Underfell belongs to AU Community(?) Y/N belongs to you (and Fell) Riley belongs to me, I guess. She's a made up jerk.
Depression... A Sansest Story. by Undercorn1
57 parts Complete Mature
Everything was running smoothly for the Star Sanses on this amazing day. Ink was drawing happily, Blue was running around chasing butterflies, and Dream was reading! Until we look a little... deeper. Dream was fine. But Ink was thinking about things much darker than his smile gave off. Blue, on the other hand, was thinking all happy thoughts! To an outsider. To anyone else, he would never have depression. To others, he was a cute little innocent boy. But only he knew the truth. Dream was the happiest out of the bunch. Not really surprised, are you? Let's check in on the 'villains' as you may call them. Dust and Cross were running from Killer, who was tightening his strings on his hoodie, NIghtmare was reading just like Dream, skimming over the page, Horror was playing with his ax, and Error was knitting. Who is depressed? Ha. You really are blind, dear, dear reader. Have you yet to notice that the strings were on Killers wrists, so they wouldn't show? Or the way Nightmare never turns a page in his book? Geno was running away from Reaper at that moment, who was laughing. Reaper was slightly sad because he had to reap some souls, but Geno was the one suffering. Fell was being beaten by his brother at that moment, and no one would save him... "You can't be saved without help." This involves Crossmare, Dustberry, Errink, Afterdeath, Kreme, and Scifell. No, I will not be using Horrorlust in this book because I just don't get the ship. Sorry Horrorlust shippers... I really got this whole sanscest thing from Bubblyship and __Purple_Fluffball__ so go check them out AFTER you read this. Please read... This is very depressing, as you can probably tell. 0-0

Two stories, brought together by twists, turns, and a mess of events. (Y/N), a kindly soul from Recoverytale, finds themselves assuming the role of hero, a role they never wanted. Although they are safe with Dream by their side, no one else is. And that simply isn't fair, is it? (N/N), a bold adventure seeker from Recoveryswap, is desperate to find the Nightmare they loved-desperate to save him from the Darkness. But of course, it's never easy to save someone that hardly wants to be saved. The two souls both long for it all to end peacefully. They both wish for their happy ending, but it'll take more than hopes and dreams to get it. Meanwhile, Nightmare is in a state of divided conflict. As he rebels against the Darkness, the Darkness fights back. Nightmare is just as desperate as (N/N)-if he doesn't stop himself, the Multiverse will be torn apart at his hands. Dream is trying desperately to both protect (Y/N) and save his brother. But there's no time to save both of them before the Multiverse collapses into chaos. As a war rages on between positivity and negativity, (Y/N) and (N/N) are forced to work together-but it's not only their lives at stake. It's the life of the Multiverse-and a fallen prince-that's on the line. And they're the only ones that can stop it. ---- (In order to understand anything that's going on, read Expiation and/or Divinity. Both can be found in my profile.) ---- [Dream and Nightmare belong to Jokublogs. The Sans' belong to their respective creators. I only own Recoveryswap and Recoverytale, and of course, this book series.] Book 3 of the Dreamtale Trilogy
