    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. Diana is soon saddled with five skeletons who seem more intent on annoying her to death than anything, and despite all rationale, finds herself drawn to their dark leader for reasons beyond even her comprehension. Too bad it seems like everyone in the Multiverse seems hellbent on getting between her and Nightmare.

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

    Summary

    A dream SMP story. If any cc's are uncomfortable with this, I'll take it down immediately.

    “I made the first move, it’s your turn next.” I winked at him, and his smile turned up a notch.
    “How about one more kiss for good luck?” He cocked his head, his goofy grin making my heart do backflips.
    “You just got one. How about I kiss you again after you get back.” I tease, backing away.
    “I’ll be waiting.”

    Summary

    Cassandra never saw herself as anything special; average face and an average life. She never thought of herself as important and actually had hated herself for the longest time. She had a few friends, but she only felt as if she were holding them back. At least that was what her cruel thoughts told her. It didn't help that she viewed humanity as cruel as a whole, but there was some hope after the monsters returned to the surface two years ago. Most people in Ebott City have accepted them, but there were still some racists that despised those that welcomed the monsters with open arms. Cassandra never bothered trying to meet the monsters, but fate had other plans....

    On a kinda Hiatus? I'm slowly working on the next chapter, but it will be a while... See My Story for info :3

    Summary

    It was a nightmare for you before you finally left the mansion. Heather had them all wrapped around her finger and made your life hell. At least you finally got away.

    Then three years later you see on the news- the mansion was used for monster trafficking. The darker parts of society in other countries were always looking to get their hands on a monster to study.

    With the autonomy Sans was afforded by monster society, royal guards and police never suspected the mansion was where monsters were being kept imprisoned after being kidnapped. A bloody and violent escape attempt finally exposed the secret. Now all the monsters imprisoned are free, including the skeletons who were chained for two years.
    You want nothing to do with it, but there was one skeleton you did care for- Mutt. His brother was dead and who knew what traumas he faced in the mansion. He helped you get on your feet when you left. He was there when you needed him and it was time to return the favor, regardless of who else you might meet...

    Summary

    After your little sister ran away, you decided to strike out on your own. Nine months later, nothing was different except for the fact you slept in your car. Living in a 1997 Honda Civic in the parking lot of your local Walmart was not ideal, but it was better than rotting away under the same roof as your mother. You could have run far away, but you were bound here. Bound by blood and obligation. There was no escaping family.

    The machine was broken, and it would never work again. It was a mistake Sans would never live down, ripping alternate versions of himself and Papyrus away from their home and into a strange new world with no way back. They moved to this town far from Ebott hoping to create something new. To plant roots, find meaning or tie themselves to this world with Papyrus and Sans following at their heels. Out of guilt or obligation, no one was sure. There wasn't anyone else but each other, after all. It’d be an awkward tango wading through guilt and resentment, but everyone was trying. Family wasn’t built overnight.

    The classic eight skeletons set up with a very heavy focus on building relationships between the characters, so prepare for the world's slowest burn.
