    Summary

    It hasn’t been an easy 15 years since since the barrier atop Mt. Ebott broke and monsters were reintroduced to the surface world. The uneasy acceptance of monsterkind was hard won by many sacrifices though over the years tensions have settled into a general, though in some cases begrudging, acceptance.

    You are a grad student at the local university, eagerly pursuing a degree in Geophysics and Planetary Sciences in hopes of returning to the National Park Service. One step closer to the future you’ve had planned out since you were 17.

    Plans change, though… and along the way, you might undergo a metamorphosis too.
    *Please do not assume this is just a student/teacher kink fic, because it is not :)

    Summary

    Tacenda - Things not to be mentioned or made public; things better left unsaid.

    He knew full-well that this story of his should not be shared. Yet, as he ran boney phalanges over the rough surface of his eye-socket and down the crack that stopped just above his teeth, he wanted nothing more than to let the words spill from his mouth. To let all the tears spill down his cheeks and ramble on about what had happened that made him so broken. Then maybe, just maybe, the weight on his chest could finally be lifted.

    Summary

    More scrapings from the bottom of the fail-barrel of my Degrees of isolation series.

    Frisk accidentally gets Conarith killed and has to deal with the consequences. Or at least, they would have if they didn't know how to SAVE/LOAD. Instead, they must deal with the consequences of NOT dealing with consequences.

    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

    Sans bit off more than he could chew when he took in a stray off the street, little did he know his new pet would be harboring a very big secret; and little did the stray know that she'd end up in the household of some very curious brothers......and that her choice, whether to stay or go, would have a huge impact on her heart.

    Summary

    Part of the Degrees of Isolation one-shots series where you see what I mean when I say the OC is a Kingdom Hearts OC with (badly) filed off serial numbers.

    Conarith Canterbury meets all of Frisk and Toriel's friends for the first time. While that alone is nerve-racking enough, she is even more anxious to meet Sans, the monster whom had saved her life from certain doom in the frozen wasteland that Snowdin had become.

    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

    Bitties are humans who use to be full size, now with no memory of their past lives or even their name. For their own protection, and to improve relationships between monsters and humans, bitties are placed at adoption centres, awaiting to be adopted by monsters.
    Tina is one of said bitties; a rare adult bitty, and while she can't remember her past, she wishes she could forget the monster who tortured her to the brink of madness. Now she spends her days in the adoption centre, wondering if broken things can ever be healed or if she can truly trust that grinning skeleton.

    Summary

    Viola has a good life. Not exactly the most interesting, but not the worst.
    Heh, that's what she thought, before her curiosity went too far, and she found herself in a world entirely unlike her own, full of magic, guns, and a skeleton.

    Bloody hell.

    Summary

    Some people are used to being invisible, never being noticed. That's how Tabatha lived, as nothing more than a passing face in the crowd, meaning nothing to those she saw every day. But Papyrus just couldn't understand why such an intriguing human could stand going unseen. (Eventual Papyrus x OC because there aren't enough of those fics in the world. Slow burn)
