    Summary

    In a Multiverse where Ink and Error retire together after falling in love. Dream is now the new leader of the Star Sans and protector of the multiverse.

    With Error no longer a threat, Dream focuses his effort in pacifying the other big threat to the multiverse, his brother Nightmare. In an attempt to cure his brother of his curse of negativity, Dream uses a rather volatile serum from a rather lewd AU.

    How will this series of events play out? And how will the multiverse fair without Ink and Error?

    Summary

    A certain short, pun-filled skeleton has been friends with a certain tall, flame-covered elemental for several years.

    Life was great... until the human came along. Frisk, along with the Royal Family Ghost, AKA Chara, murdered and dusted their path to the end so many times Sans can't even keep track anymore.

    When an unexpected event gets thrown into the two lovebirds' mess, how will the pair react? Will they finally realize and acknowledge their feelings for each other like real men? Will they make out!? Nobody knows... except for of course yours truly..

    |***TAKES PLACE BEFORE/DURING A TRUE PACIFIST AFTER SEVERAL GENOCIDES, WILL INCLUDE MINOR MENTAL ISSUES FROM PAST RESETS!! ALSO MAY INCLUDE NSFW LATER ON!***|

    Welcome to my first ever work on AO3! I will try to upload weekly, but please bear with me as my schedule is all sorts of screwed up.
    Anyways, this is a WIP Sansby story, with plenty of (hopefully) fluff, angst, and pretty much anything else mentioned in the tags (if you haven't already, go check those out). But enough blabbing. On to the story!

    Summary

    This is a collection of random story ideas that are around 1-5 thousand words each; they weren't long enough to stretch into their own works. But yeah, this contains headcanons, short stories, or just stories that fill in the gaps... (Hint Hint). This gives more insight into what's going in this version of the multiverse. There will be things explained here that were mentioned in the first work. Just as a heads up. Also, this doesn't have a schedule either. Yeah... I think that covers it... for now. Also if you are reading my main story and then notices the ships change here, that because something will happen in the main story. So that's also a small hint at what's to come. With the ship StageBloodLust, I didn't actually see Echo in the ship better than Horror, so that changed. Sage is one of my Au's, if you didn't know, and just seemed to click better with Lust and Horror rather than Lust and Echo.

    Summary

    A day... that's all it took for my world to come crashing down.

     

    A week... was all it took for me to fear the door.

     

    Six months… was all it took for me to become numb.

     

    A year… was all it took for them to find me.

     

    Four Years... was all it took for him to come into my life.
     

     

    I wanted a Papyrus fic that does not frame Papyrus as a naive idiot. He’s proud, strong, and observant. All together witty around his silly behaviors (:

    Summary

    Undertale is a popular video game, but it knows when it's being played. Five of its characters can remember the way the world used to be, even after the game itself resets, but until now they have been unable to affect the outcome for the better. As such, this game has never once gotten its happy ending and, as such, is adapting. Two wrongs make only a greater wrong, after all.

    This is No Mercy Route Number Ninety, and five alone will have to change the course of the game, before the game changes them.

    Summary

    Sans dedicates every waking moment of his life to keep his little brother safe, happy, and blissfully ignorant of their father's depravity. He lives for the moments he can steal away with Papyrus and pretend their life is normal, happy. But as Gaster's stranglehold on Sans' life begins to loosen, he finds more to live for. He finds himself fighting back with disastrous consequences. And for the first time he's willing to risk everything for a chance at not just surviving, but actually living.

    Grillby has loved Sans from a distance, not wanting to complicate the young mans' life further. While he doesn't know the depth of Gaster's hold on Sans' psyche, he knows Sans doesn't feel safe at home and he knows the bruises he carries are deliberate. When Sans starts to butt heads with his father over the budding relationship with the gentle barkeeper, Grillby does his best to comfort and care for him; supporting him through the trials of recovery as their lives become inextricably bound together.

     

    *A prequel to the events in Lucky Strike and Us In Motion which are set in the Underfell AU.

    *This is a stand-alone plot.

    Summary

    After a long and painful six months, Sans manages to land himself in a mental hospital after an attempt on his own life. Will he recover? Or will he spiral back down into despair.

    MIND THE TAGS! Takes place directly after "Oh Ana" but isn't required to understand what is going on. I recommend reading it first though, as it is the prequal to this fic and what started this series in the first place.
