    Summary

    You are an illegitimate child, the result of the love of a werewolf and a vampire. In the books, creatures like you were exalted above the rest, possessed of immense power and skill. But in reality, it's the opposite. Like your inability to digest blood, or your inability to use vampire hypnosis. And those are just some of the problems half-breeds like you have...

    Your family on your mother's side refused, couldn't accept you, so all your life you grew up under the wing of your father, who owned an elite vampire establishment in Ebott. Humans often went there to make unusual acquaintances or earn converts.

    So when word spread inside the club that one of the female customers, who owed your father a debt, refused to pay under the pretext that she got pregnant by her boyfriend, you became involuntarily interested. Because her boyfriend was a monster...

    Summary

    The Fell brothers are on the surface and out of the hellhole they call home. Edge has a good job and friends and hobbies. Red is still the piece of shit he's always been, but now he has Sans, who despite his best efforts to hide it is the best thing that ever happened to him.

    If Red would stop making excuses and allow himself something good for once, he could actually be happy for the first time in his life. But maybe he's right that everything is temporary. After all, in a world where there's still an undeniable tension between monsters and humans and everything can reset at any time, is it even worth getting attached? Is being happy, even just for a little while, worth the pain that comes with it if everything he loves is lost?

    Summary

    Dr. Sans Serif has been chosen to conduct an expedition to a newly discovered planet. There's a lot riding on this expedition; what Sans finds on this new planet could change the course of life on Earth.

    It’s a six week journey aboard a ship that is crewed largely by minimum risk offenders looking to trade labor for a commuted sentence that are kept in line by a group of soldiers led by Commander Red Gaster. At first the Commander seems to see Sans as nothing more than an assignment, someone he was charged with keeping out of harm’s way both aboard the ship and at their destination. But as they get to know each other, Sans is determined to win him over, though he needs to do it without losing focus on what he's come this far to achieve.

    Summary

    You've worked with difficult people before, but...these skeletons were on a whole other level. If Undyne had warned you just how crazy they were, you probably wouldn't have agreed to help the queen in the first place.

    But due to unfortunate circumstances, Mt. Ebott was the safest place for you to be. And in order to stay, you had to join the Royal Guard.

    Now, with threats of war breaking out, you find yourself torn on whether or not you should help this mixed bag of good and evil monsters.

    But one thing was for sure...you'd sooner die than give up your newfound refuge. You were ready to fight and protect your home.

    And these skeletons didn't seem to understand that you were serious.

Just as when they try to take a step back from the chaos of their life, Frisk gets erased from existence.

    Summary

    A century after King Mets rose to power in the UG, it's the happiest place under the Earth, with all of the traditional monster lands reformatted into theme parks for humans to enjoy.

    Of course, there's a seedy underbelly to every happiest place, and most skeletons live in the middle of it. An elite team of thieves, still wracked by a devastating loss, are going after their biggest job yet, one that will turn the UG upside down. To pull it off, they need the help of Stretch and Blue, two low-level thieves working out of Winter Wonder World park.

    All the while, the only skeleton member of the Royal Guard, Black, is tasked with making sure no one gets too close to King Mets. When he gets word that the 100 year celebration is at stake, he must do whatever it takes to save the day.

    A story told in 250 words a day.

    Summary

    Papyrus is sick of Sans treating him like a child, and (Y/n) is tired of being who everyone expects her to be. When these two find each other they both immediately hit it off, but will Sans or her family try to interfere in their good times? Probably good thing the Great Papyrus is good at sneaking out and (Y/n) is bold enough to be herself! This story is completely self-indulgent and purely smut based plot (its barely there), but if you wanna come along on the journey of Papyrus getting to say fuck and be an adult strap on in friend.
