    A Snowstorm was due to pass Snowdin that day. It was just starting now. Papyrus was lucky that he was able to get home early with no knowledge of what was in store for that day. Sans was slacking off on the couch as usual so he told him to do the laundry to have more warm clothes for later that night. After storming off to his room the returning with with a new pair of clothes on he went to check on his brother to see if he was being productive only to find a concerning mess in his brother's room with him too gone. The room looked like it was attempted to be cleaned but unintentionally got messed up after something happened. He too was concerned but brushed it off knowing that his brother would disappear suddenly sometimes. But the mess that was left and no warning of his disappearance would disturbed him as the days went on. --------------- Inspired by; Oh Brother by FailMedic Who Can You Trust When the World Wants You Dead by RiddlePanda Pills by BubblyShip life's a game, life's a joke--fuck it why not go broke by cashtastrophe Out of House and Home by TaraxacumClocks (DandelionSea) And some others <3

    The barrier is finally broken, and at last all of monsterkind are free to walk on the surface. Again. Sans the Skeleton is skeptical. Why bother getting excited for something that's just going to reset? This is not the first time the barrier is broken, and probably not the last. He feels the need to take a break for everyone else's enthusiasm and wanders to the ruins where he encounters a ghost of his past. The result of that meeting is something he has been hiding for a long time and that he's determined to keep hidden.

    Have you ever wondered that out of the thousands of humans during the human and monster war that not even one sympathized with the monsters? I bet you do, for I certainly have. But perhaps you haven't heard of the story of The Lady in Green. There are many others before her who helped the monsters but her story is the most tragic and well known. And who am I to know such a story that even you don't? Well that's something for me to know and for you to find out. Preview: "Crunch Crunch. Snap!" Kimora wakes up with a start, eyes blinking slowly as she sees gray paws. Slowly she starts to look up, breath catching in her throat as she starts to recognize what she was seeing. A bipedal monster covered from head to toe with flint gray fur with tall cat-like ears accompanied by a long slender tail, orange eyes with a face of a mountain lion, with sharp thin fangs that protrude out of its top lip as it starts to open its maw. It was at that moment that Kimora remembered the scary bedtime stories her mother used to tell her when she was a child. That if you were a bad kid the monsters from the forest would come over the village in the middle of the night and drag you into the woods. And no matter how much you screamed, no matter how much you struggled, the monster's magic made it so that no one could hear you. And then when the monster goes past the village's borders they would devour the naughty children alive. Suddenly she felt like a kid again as she could hear her heart thundering loudly in her ears as she sat frozen on the ground. Midnight claws flash in front of her face, ones that can easily tear through flesh. The monster has come for the naughty child. And that child was me.

    Intro: The barrier was down. It had already been four week. Most of the humans were not pleased with the monster arrival, but since Mont Ebbot was a bit far from the city and that no one ever goes their (for most part of the population at least) they allow the monsters to rebuild their society on it and around it as long that they keep their self far away from the city. With their magic it only took a few days for everyone to be set .It was a new start for monster kind, now they would only need to make their relation with the humans better. Everything was for the best; well it was until the little human that had free the monster got her secret exposed. --- -A/N- -Undertale and all of it's characters belong to Toby Fox -My first language is not english -Frisk is a girl in this story -I don't know when I will be abel to update but I will do my best to not be to slow -Don't esitate to give me some feedback it's my first fanfic :) ---
