    Summary

    Strange beasts lurk in the woods, deep in the hills where land sinks far, far into the earth. Where darkness holds the dangerous creatures, howling and prowling well past midnight. And at the edge of the large forest is a little home.

    Summary

    Once upon a time humans and monsters went to war.

    Once upon a time humans lost.

    Once upon a more recent time Papyrus' brother Sans got a promotion. And now Papyrus was off to buy him a human. His new lord only deserved the best and with that he brought home what most would have deemed the worst.....

    And Sans couldn't have asked for anything more.

    Fighting was her only grace in a world where she was never the one in control. But now faced with these two new adversaries... even that may be torn away from her. Just like everything else she has tried to keep and protect.

    Summary

    Eve Rhyden is a well-kept secret and is fiercely protective of her younger brother Kenji. The measures set in place to protect her have unfortunately caused her to be introverted and friendless, but she's had it drilled into her that her duty is more important than her own comfort. So how is it going to sit with her when monsters start popping up and try to butt into her locked up life? Lot's of fuckery and angst of course!

    Summary

    Monsters have returned to the Surface, with Frisk leading them to new hope. Things, however, are not as they seem or once were. Mages still control the world, although they are not as strong as they were thousands of years ago. Because of this, they cannot seal monsters away once more. Instead, they enact a new policy. Monsters were to be put up for slaves. Anyone wealthy enough to buy one could do what they wish with their slave. House work, cooking, gardening.... or something worse.

    Destiny Chomitz, a mage with incredible power, buys slaves, not to use them, but to protect them from the rest. What will happen when a relationship with one turns into something a little more than she expected? Or when said monster's significant other comes into play?

    Summary

    This universe shouldn't exist, but it does. You shouldn't be in it, but you are. Life is just unpredictable like that, no matter how infuriating it can be.

    In a universe where monsters won the war, humans were hunted down and either killed or tamed. They were then split into the two classes of pets and workers. Workers do manual labour and pets are basically what they sound like. You've ended up here as a pet. Not by choice. Things happened and you ended up in an animal shelter where you've gained the attention of four short skeletons. You have no idea what they want from you, and you're definitely not sure you're ready, but life won't wait for you to be ready. It's time to see what they have in store for you.

    Summary

    You've been through shit you shouldn't have to anymore, so, in order to protect yourself, you've been separating yourself from the outside world little by little. Daydreaming, music, novels, fan fiction, video games keep you the most distracted. The last game you played was Undertale, you read a bit about its AUs. You end up inside one of those AUs, but can't remember how you got there. How does it affect you to be there? You're not the innocent and cute teenager that makes Sans or Papyrus fall in love with you, like most fan fiction stories depict. You're a woman, around her 30's, just divorced from an asshole that used you as a shared sex toy for about 10 years.

    Summary

    Long ago, a child ventured to the mountains with a goal to find the monsters that had been locked away underneath. They succeed but are met with a new obstacle...the world above has changed.

    A skeleton monster, who has never seen the sky and lived his life in hopes of seeing it with his sibling and friends one day, finds himself seeing the sunrise for the first time. Yet, must find a way to survive in a world that is harsher and straight out of a horror movie.

    A girl from the surface faces horrors that wish to devour her at any cost. Yet, she manages to persevere and lives day to day with help of a gun and something inside her that is as old as the ground itself...magic.

    Life on the surface is not how it should be. it's wild, the buildings are ruined and slowly being taken over by nature, and danger lurks around every corner, but the humans who live here are determined to battle and rid the world of these horrific creatures and their master- no matter the cost.

Though, you weren't expecting things to be taken so far... and you'd be lying if you said you weren't enjoying your time with him. Just... don't mind the depression.

    Summary

    At the young age of seventeen, you didn't know what to do when you had a child. You didn't know what to do when your family disowned you and threw you out, nor what to do when you moved in with your abusive boyfriend.

    But when your child, merely five years old, vanishes from your life, you put a stop to it. You left behind the disgusting man that dared harm you and started anew, pulling yourself together. A new job, a new apartment, a new mindset.

    And with monsters coming into the world, you find yourself enjoying their company...until you spot a certain monster holding hands with a very familiar person and your entire world goes into chaos.

     

    ...You knew they were still alive.

    Summary

    Life in the Underground is its own thing - sometimes happy and sometimes sad, but always something that they're in together. And in the end, that's what counts.
    A series of stories about the banishment of monsters, building an existence out of nothing, and daily life in the Underground.

    Technically a prequel to "These are our Days" but it's entirely possible to understand one without the other.

    Viola has a good life. Not exactly the most interesting, but not the worst.
