    Summary

    Nightmare and his gang encounter a mage and decide you know what? Their castle could use a decent maid. Yet, as in any fanfic under the sun, there's a twist, and there's something more to this mage--who requires Nightmare's special brand of magic to stay sane.

    Started out as a reason to write Nightmare porn and ended up having an actual plot. Lord help us.

    Summary

    Ever since the War, magic humans have been training to kill all monsters when they escape. They've even built a special school designed for teaching young magic people how to use their powers for destruction.

    Y/N was a magic person, born of non-magic parents. But Y/N is not a vicious person and does not want to hurt anyone, and is ridiculed because of this. Feeling worthless and broken, Y/N decides that if she can't follow her chosen purpose, she's better off dead.

    But she finds a new world to call home.

    Summary

    You went to the bookstore one day to buy some manga.

    You got a whole lot more than you bargained for.

    You end up somehow saving the Royal Scientist's life, and her fiancée can't thank you enough for it.

    So that's how you find yourself surrounded by people who love you for who you are and don't want you to change.

    But what's up with these strange dreams you're having? And, why does a certain punny skeleton get so spooked at the number 17? And...who is that tall skeleton with cracks in his face that you keep seeing in your dreams? Did the ambassador of monsters just join your swim team? Can this summary get more cliché?

    Summary

    (Y/n) lost her job, which sucks. If only she hadn't lost her second job, and apartment, as well! Now all she's got is a camper full of her crap on the back of her truck, and nowhere to go. At least she found this campground, even if it is in the middle of nowhere, and looks like no one has been around it for a while, and a skeleton with a head wound tries to make her into a meal... Rough start to making new friends, but his brother is sweet enough!
    And then there's the other skeletons who inhabit the other cabins, who all look vaguely similar... Their explanation of "cousins" only goes so far, but there are more concerning things to worry about, like how almost every skeleton is trying to get into her pants, their heats, and where her clothes, particularly her socks, keep disappearing to?!

    Summary

    So I'm going to put oneshots from the actiones secundum fidei universe here.
    These will range from happening before the series started to off-screen events.
    Let me know if you have any requests, I can't promise I'll do them but I'll consider them at least.
    I might end up writing some onehots that don't contain smut so for now, titles that look like *this* contain smut and all others do not

    Summary

    You, the reader, have been in the underground for a good five years now with no means of escape in sight. You have tried everything, but ultimately, it's up to the monsters to gather the humans souls necessary for escaping. The only problem is, a few years ago Sans came back from the Core with a huge hole in his skull and ordered the residents of Snowdin to eat humans instead of harvesting their souls. And you...well, you're a human.

    Semi-based off the comic by Sour-Apple-Studios. If you haven't checked it out, go and do so.

    Reader is neither Frisk, Chara, nor Aliza.

    Updates on Thursdays or Fridays.
