    Summary

    (This is a fanfiction on Undertale mainly inspired by the “Dreamtale” AU)
    Nightmare had always been the perfect prince. He was smart, much smarter than the kids of his age, he was polite, kind and calm. He had a great ability with the sword comparable only to his love for books and tales.
    Nightmare had always followed all the rules, after-all they were there for a reason right? But, as day after day he watched how his kingdom stayed grey and quiet unlike the bright and vibrant ones he read about in his stories, he wondered if maybe, breaking rules just that one time couldn’t be that bad right? After all he was doing it for a good reason, it was just his duty as a prince to seek for his people’s happiness and wellbeing right?
    With that goal in mind the young prince made his decision, and just as the heroes he loved so much reading about, he left the castle, his home, disappearing in the night to start his journey.

    WARNING

    Summary

    Traveling through the void was a nifty trick, but one Sans tried to avoid doing unless it was in a pinch, like when he woke up late for his shift or was too tired from training with Alphys to walk home and the Riverperson wasn’t stationed in Waterfall. (Also, his brother was so jealous of Sans’ “shortcuts” that it made the shorter skeleton feel guilty whenever he used them.) However, tracking down the source of the magic was a critical priority. There could be a monster lost in the forest and in need of assistance; or someone very dangerous who needed to be confronted before they stumbled across Snowdin Town and hurt anyone.

    It turned out to be… a little of both.

    Summary

    Y/n is Ink's other half. She was created the moment Ink was but her existence wasn't meant to be known. When Ink left their Au so did she but ended up in what she calls 'Reality.' As Ink makes the new Au's Y/n makes the 7th humans that fall and all before them. She also creates the humans that live on the surface. Her existence is still unknown but she knows Ink and Error. She watches them and makes sure they don't go too far. She has never been forced to intervene, not even during the x-event. While watching Ink and Error she had suddenly gained a soul-mark. She was more excited than usual and she searched the Au's for her perfect match. She found them in the Undertale Au and quickly made a portal to the Au. Y/n met one of her soulmates which led her to the rest of them and she couldn't be more happy. Literally.

    Summary

    Ink is one of the kids with the best reputations in school, so nobody would ever expect him to ditch. But one day he takes Error, one of the school bad boys, into the woods to show him some of the cool stuff he's seen. After they graduate, they spend their days exploring the woods, and going on fun adventures with their boyfriends.

    There may be mature themes such as lemons and swearing, but I haven't decided yet.

    I do not own the characters.

    Summary

    Fresh walked through the forest. Where was he? Who knew. All that mattered was getting out of there. He could hear the sounds of the night creep upon him, and he turned his walking into a run. He was defenseless ever since the gift of being emotionless had run out.

    Fresh collapsed out of exhaustion. He couldn't run anymore. Everything hurt inside, how did people deal with this normally? He heard a noise come from the bushes around him, but he did not investigate. Instead, he stayed still and looked up.

    It was easier to go out without a fight.

    Summary

    Error has no idea where or who he is.
    Strange skeletons who turn up one day after you're chased out your Multiverse? He can deal with that. Being mistaken for people he never was, seeing the things who chased you away, and falling for someone, however?
    He's working on it.

    Summary

    DREAMTALE AU
    I am terrible at summaries
    Anyway, I decided to train a bit my writing by doing a little fanfic much simpler and shorter than my other project XD
    I hope you'll enjoy this little angsty-fluffy dreamtale fanfic! I will also accept suggestions for future chapters in the comments!

    Nightmare didn't regret killing the villagers.

    They were greedy and evil.
    They deserved to suffer and die in the most horrible ways.
    They always treated him as if he was a disgusting cursed monster when they were the ones acting like one.
    He wanted to make them pay for all the pain he had suffered because of them.

    But ... what about Dream? Happy, naive, little Dream. The light in the darkness, the hope in the sorrow, the sun of the night.

    The little brother who always cared about him. The little brother who always tried to make him smile. The little brother who didn't matter what the villagers offered was always back to him every night.
    He didn't deserve to suffer.

    When the guardian of positivity turned stone in front of his eyes, Nightmare snapped back to reality, regret and guilt overwhelming him.

    Will he be able to get back his spark of happiness?
