    Summary

    -This will probably turn into a series later-

    (Y/N) is an AU sort of god, she helps Core Frisk with tracking down certain AUs. She lives with Ink and his “sister/trainee” Sharpie. (Y/N) and Sharpie had become good friends over the years, usually camping out in what’s left of deserted AUs and generally having a good time.

    Then came Cross, stealing half a soul. Then came the stealing AU parts. The destruction of an Underswap timeline, and the true meaning of the X-Event.

    Ink gave you two choices. Stay with him to continue his “game”, or leave and suffer. (Y/N), scared of what the soulless creator would do, had chosen to stay. Sharpie, who Ink had trusted her, had ran off with her eyes filled with tears.

    The young woman thought that Sharpie was gone forever.

    Summary

    Everyone knows about the monsters and the monsters banishment, but long have people had tales about creatures that were not monsters. Creatures that were known as Fairies or Fae or the Fair folk. They've always been around, and once the monsters were freed many of the fae could not in good conscience hide in their hidden cities as the monsters were mistreated again. But nor could they just announce to the world they existed either, instead the fae put together a system to get monsters out of the clutches of humans and to safety in their own cities and villages.

    This is where you come in, you're a Puca. A shapeshifting fae working for the Elderwood Stronghold in the Rocky mountains. You were a scout normally, but your commanding officer was about to throw a major wrench in your normally solitary lifestyle in the form of a nervous, somewhat twitchy skeleton. You didn't ask for this, you didn't want this. But this was your job now, he doesn't trust you much but he trusts everyone else even less so you're stuck.

    Summary

    A run-away Princess, two Knights in shining armor and an Evil Necromancer. Sounds like a familiar story, right?

    Wrong.

    You're not really a Princess, you're just the daughter of an important Duke who wants to marry you off to the crown Prince rather than do any of the things you are actually good at. The Knights in shining armor? People who your father lied to and hired to take you back home against your will. The Evil Necromancer? The person who has protected you and acted like more of a Mother to you than any court floozy could be.

    You really just want to live your life the way you want to but these skeletons really keep getting in your way. But as much as you hate to admit it, you think you might be getting attached...

    Summary

    Sans is just a normal monster in the underground. One day, he starts getting weird dreams about a girl. A human girl. Who is she? Papyrus is no help, since he's such a jerk, and he has no legitimate friends to ask what these dreams mean. He has no choice but to assume that these dreams mean something...

    Frisk is absolutely terrified. She was cursed by Rose, a petty warlock human (the first in 80 years), to be banished from the village, and never to return. Frisk literally could not help but fall. It was the farthest she could go in a single day, just wearing that stupid red and black sweater, and shorts that hardly matched. Fortunately, she has her handy Swiss Army knife to do...well...anything that might need a knife, saw, or any assortment of screwdrivers.
    But can a world full of hate bring anything else other than pain and fear?

    Summary

    Papyrus gets shunted across universes and ends up in a place that is nothing like the Snowdin he calls home. There's no warm welcome to receive him; only the all encompassing feeling of danger that seeps into his bones. Though, maybe calling them his bones would be a bit of a stretch considering he's no longer in his own body. Instead, he has a scar over his eye, pointed claws and teeth as sharp as knives. He's desperate to get back home but, between searching for a way back and keeping up appearances with a sad little skeleton that looks an awful lot like his brother, everything is kind of a mess.

    He can't stay here though. There's just no way.

    So he'll simply have to try harder.

    Summary

Finding an ad in the paper for everything you could want in a place only set back is they are looking for male applicants only... oh and the other tenants are monsters not that you mind. Maybe if you could go in person you can plead your case and oh my goodness they're all skeletons.
