    Summary

    You are a twenty-something university student, alone on Christmas because of your own choices and now the strange shape in your dreams is meeting up with your day-time hallucinations and trying to convince you that you've got just the dumb, bright red soul they need to open the underground? Sure, I guess that might as well happen.

     

    This fic is very self-indulgent, you're gonna have to suspend disbelief hardcore when we get into the thick of it. Slower updating speed but never dead!

    Summary

    You gently pushed the door and here you were, outside of the ruins. The first thing to hit you was the cold, then the realization that you just left the only safe place available to you. The second thing to hit you was that wow, maybe it would be warmer if you weren't wearing just some t-shirt and old jeans. The third thing and the last, was that now you were aware of holes in your sneakers. It felt like it was going to be a great day.

    Summary

    He had been having dreams of the same cute little drunk human for almost a year now. They were vivid and she was fun to talk to, and he was convinced that his 'dreams' were accidental manifestations of her magic. Magic she didn't even realize she had. But that magic may have just pulled her into a world of danger.

    Summary

    You’re just an average, happy human, going about life, trying to forge your way in the world. Fortunately, you’ve landed a nice job that pays well, you’re steadily and reliably working your way out of the debt you gained from moving to the city, and you found a great apartment (with a chill roommate, Sans, a polite skeleton monster with puns up his sleeve and an indecipherable gaze) for surprisingly little rent.

    Everything’s fine.

    And then, without warning, two more skeletons seem to show up out of nowhere at your and Sans’s shared apartment. The first to appear is Red, a hot-blooded, sharp-grinned alcoholic who isn’t shy to share his less than savoury intentions with you, with crude gestures and pick-up lines galore.

    ... And the second is a tall, broad, but quiet skeleton who immediately goes by the pseudonym Skull, sporting a huge crack in his head and a single, engorged red iris, that never seems to stop staring at you.

    You’re not sure why both of them won’t leave you alone, or why Sans seems so desperate to stop them from interacting with you... But hey, what harm could come from it?

    Summary

    Inspired by Lady Darkina's 'Between Flesh and Bone', and other reader insert/OC insert Undertale fanfictions:
    This story follows Sans the skeleton (a lazy yet respectable skelly monster) and his new-found crush (we'll get to names, later), after Frisk's Pacifist Run when they're on the Surface. Leaving the Underground is a huge deal...especially with all those little details Sans had to deal with at one time (and the legal drama, too). PTSD is real, my bros...and this is how YOU help him deal with it.

    Enjoy!

    Summary

    You watched him unwrap his lunch, pouting.

    “C’mon, man. Not even a bite?” He started eating and you groaned dramatically. “I’m starving. I’m dying right in front of you. You’re killing me, Papyrus.”

    “good,” he muttered around a mouthful of food.

    “Wow, rude. I have no idea why we’re friends.” You sighed, eyeing the glittery burrito.

    “because you like to mooch off of me,” Papyrus snorted. He finished it off, cracking a grin when you whined in distress. “besides, y’know i only eat this because m’lord made it. he can always tell when i give it away. i’ll get ya something from a food truck later.”

    You nearly cried. “Thank you! I swear, I’ll pay you back when I’m a millionaire.”

    “so, never?”

    “I’ll try.”

    Papyrus shook his head with a grin, reaching out to pat your head. “guess that’s better than nothing.”

    You beamed, soaking up the affection. Papyrus always had your back.

    But… you were still so hungry. You worried that soon, food trucks wouldn’t be enough. Nothing would.

    Summary

    You're from the Horrortale universe.

    A universe where everyone has suffered-including your favourite skeleton brothers.

    You were merely 15 when you fell to the underground-a lot has changed in the four years you've been there. Somehow, along the way, you'd convinced the butcher himself to not slice you into mince meat, and even moved in with them at some point. Nowadays, you spend your time struggling to survive WITH the skeletons, rather than against them (thank god).
    Though things are about to take a drastic turn. You thought one pair of skeletons was strange enough- try 8 for size.

    Summary

    The city of Ebott was not one many humans resided in. It belonged solely to the Monsters, and was known as the Underground. The Dreemurr family had overseen the running of their cartel for decades, building themselves up as a fearsome group. There weren't many human families that even came close to the power and wealth they held, nor the formidable soldiers. Namely their two best hit-men; The Judge and The Executioner, known affectionately to most as the 'Bone Brothers'.

    Of course, many had tried and subsequently failed to stake claim to the long held throne. Things like that were usually swept under the rug fairly easily, but something about these latest challengers..
