    Summary

    There were flashes of memory from before. But when you wake up in a bed that isn’t your own, only to be greeted by a monster you’ve never met, you have no choice but to trust him. You feel as though he’s familiar in a way, that you’ve seen his face, or one like it... two, three times before? And there’s an itch in the back of your brain, like there’s something you left behind, someone even.

    This is the story of a human who came to be found by the Horrortale brothers, and nursed back to health after an “accident”. They can’t remember most of what happened before they were found in one of Papyrus’ many traps, and come to find solace in staying with the two skeleton monsters.

    This story takes place on the surface, in the normal timeline, but the skeletons have been brought together by means other than Sans’ machine.

    Summary

    Failure. Reset. Failure. Reset. Failure. Reset.

    This time, you fall into the Underground weeks before the Seventh child arrives. But you’re not a child. And not many monsters have ever seen an adult human in the Underground. Not even Sans. You definitely weren’t expected. But maybe you’re supposed to be here? Maybe you’re the anomaly that can finally stop this endless cycle of resets?

    Or maybe you'll just get stuck in it with the rest of them.

     

    The “reader” is technically a young adult (twenties), female OC whose story is told through the second person. This was done to keep the story's POV similar to the game's POV.

    Summary

    Since coming up to the Aboveground, the humans being pushovers, peace came easy once the Monsters were released. Things were still slow, Monsters and Humans lived in a good mix. Those who didn't want to be around have their own part of their territory while Monsters held their own with a similar mindset. Those who enjoyed each others company had a mixed society that allowed both to live in harmony easily.

    But after a few years, things began to turn for the worst with bodies of both species littering areas nicknamed 'Kill Zones'.

    It doesn't help Sans and Papyrus as they are ordered to investigate, being one of the high ranking Monsters their Queen has as they desperately try to regrow their Royal Guard back to manageable numbers.

    Not to mention, if anything happens to humans on their watch... Well, let's say the Monsters won't become too comfortable for much longer?

    Along the way, it seems Papyrus has gotten himself-... A human?

    How will this turn out?

    A story of how little (Y/n) overcomes her autism with the help of a short lazy skele-father pushing her forward along the way. Fluff, angst, and family building ensure.

    Summary

    Word has hit the world, Monsters have reached the surface from Mt. Ebbot! But after that exciting news story and the follow ups, what happens? Absolutely nothing. Nothing changes for you, a college student, studying from the community college in the backwoods of the small town you grew up in. So, as the stories quiet down and the years go by, you forget there even is another race living among you. That is, until you meet some during a trip to a big time nerd convention.

    Based on if Monsters had a physical manifestation of their soul (dæmon/soul searcher/searcher) from The Golden Compass!
    Officially named Compasstale and made by yours truly!

    Summary

    Marrying at twenty and divorcing at twenty-two doesn't exactly leave the best image of you. Adopting a seven-year-old child during the short length of your marriage only made that worse. Now, it's time for you to move on, though you find it hard to do so.

    It isn't until you come across a city bustling with human and monster folk alike that things begin to change, the change leading you to meet new faces – both kind and unkind.

    It's then that you realize that – sometimes – what you really need is a moment of repose. You find yourself in the need to simmer down and for your mind to clear as a consequence.

    You're able to find that place the further you spend time in your new home. There, you form brand new relationships with monsters you never thought could exist – one of them in particular making you relive things you once thought were long lost.

    A save point – as you chose to call it – was something both him and you were in need of.

    Summary

    It's a place where weird things happen, and kids go missing. It's a place where everyone grows up being told to stay away from. It's a place Frisk grew used to hearing scary stories about. But someone also once told Frisk that there was Magic on that mountain, and that if they were lucky, Mt. Ebott would grant them a wish.

    Any wish.

    And with Frisk's older sister, You, practically on death's doorstep, they were willing to take any chance they could.

    And as luck would have it, Frisk literally stumbled right into the Underground and had the adventure of a lifetime. However, by the time they were able to free the monsters and make their way back out to the surface, their new friends and their magic in tow, not even a wish could bring back what Frisk had lost. Because at the end of every single run through the Underground, no matter how quickly Frisk hurried, as the sun rose over the mountain You succumb to an illness you've been battling for a long time.

    So with one final Reset, Frisk goes back farther than they ever have before. If they can't bring the monsters to You... they'll bring You to the monsters!

    It's Frisk's last hope, and Your last chance.

    You sipped at your coffee, not able to taste the caffeinated beverage. You couldn’t taste anything anymore.

    You couldn’t see the colors either. It was like you had gone colorblind but everyone else could see just fine.

    You were colorblind, but you could see some blue.

    A familiar blue.
