    Summary

    The humans that fell into the Underground, for the most part, were easy prey for Sans. Tiny, gullible, desperate. They were easy prey because they just didn't fit into the twisted, dark world that had taken shape under Mt. Ebott.

    But what happens when a human falls that just fits so... seamlessly into the Underground's growing madness? When he not only knows what's going on, but knows exactly how to survive?

    And, most importantly... when he's more than happy to play along?

    Summary

    It's been 10 years since the barrier broke.

    I'm in a family full of monster-hating humans. But my soulmates are skeletons. And these said skeletons come from different lines of life. I know family is important, but hating someone, anyone, because of who they are to me is just plain...well, stupid. So if this means that I don't run my family's "business" then so be it. I'd rather love my silly skeletons than live in a family that hurts and ridicules others because of whom they are.

    But I don't think they'll understand as much as I'm hoping.

    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.

    Summary

    Apparently a human secretly lives at the dump. Said human is also really suspicious they have been found out by their only friend Sans, who occasionally stops by the dump to talk to them. This is mainly feelgood fluff with no real smut or hard romance. You have to balance out the sad fanfiction somehow, right?

    Summary

    CounterTale: A world where monsters won the war, Frisk and Asriel freed the humans and are working to find peace between two races who only care about ripping each other apart, and because the humans successfully kidnapped the monster monarchy, Sans was magically chosen to take over. Ten years have passed since he was forcibly elected to lead and his brother is falling down and if his remaining family does die, he will give up and follow Papyrus.

    Earth 2017: I hate life. I always have. Coming home to a bitchy roommate who acts like everyone should kiss her ass, it's just too much. After a snap decision, I'm forced to run away. But the police aren't far behind and after a mistake, I am shot down and am at death's door.

    Just when all hope seems lost, Sans and I are both given hope. An unexpected visitor comes plummeting from the sky and invades the monster kingdom with sass and ridiculous drama, but ends up helping in ways that seemed impossible. As for me, I am transported to a world like that of the video game I have grown to love...with quite a few big differences that are unexpected. But regardless, I am given a new life, a new purpose, and have unlocked new powers. What could go wrong?

    Summary

    Rachel has finished up her time in the CounterTale universe as well as her time in the adventure after that. Now, she wants to try out another universe she created. In this timeline, she will replace the Reader (doing so does not affect Under the Spotlight since it's an alternate timeline) and thus only Rachel has the same Soul and Powers (and more) as the Reader did. That means...Rachel has become Sans' Soul Mate.

    What will happen this time when she meets this Sans? Given that he is everything she desires (all her headcanons), will she go crazy from desire or will he find her intensity alluring and even appealing? Well, whatever the case, this adventure is sure to be insane with Rachel at the reins...again!

    IF YOU HAVE NOT READ MY OTHER STORY, COUNTERTALE, A LOT OF STUFF RACHEL CAN DO WILL MAKE NO SENSE. TO PUT IT BRIEFLY, SHE HAS FULL CONTROL OF REALITY AND A GUARDIAN NAMED SOUL, WHO CONTROLS THE BLACK TAIL ATTACHED TO HER BODY. AN IMAGE IS HERE.

    Summary

    Monsters have never been sent to the underground. The war that raged between monsters and humans ended in a draw, but no peace treaty leaving relations tense on both sides. The earth and cities are not in the best of shape after such a war, the weather tending to vary greatly from area to area based on residual magic left behind from the fighting. Some areas are human territory, others claimed by monsters, some simply neutral with a hope of peace and calm. Thieves and bandits are everywhere, the royal guard and police force not able to keep up with their growing numbers and largely leaving them alone at this point. Technology continues to advance, with each race constantly trying to outdo the other.

    Jade lives and fends for herself, currently living in an abandoned warehouse near the Hotland district, in the more desert and neutral areas between there and the human city of Külaküla. What happens though when she stumbles upon an interesting sword leading to long journey?
