Summary
The dichotomy between black and white is your constant when it's time for you to meet the whole new civilization Frisk brought along with them to the Surface.
As a parent, it's not easy to trust others when they've hurt your child.
So when that new civilization decides they owe Frisk both for saving their kind and for still hurting them during that process, you've got plenty to say to them.
Forgive as easily as you once did with others during a stage of naivety? Oh, hell no.
They better have a good reason for hurting your child and an even better one for wanting to be a part of their family.

Summary
Apeirophobia: the fear of eternity; endlessness; the infinite.
—
Giving up and starting over feel the same sometimes. It’s difficult for Sans to do either when he can’t let go of the past. It’s difficult for Papyrus to do either when he doesn’t know what that past is, even when it’s rearing its ugly head.
Papyrus’s attempts to stop Sans from lying end up rekindling an old Connection, for better and worse.

Summary
You never thought you would move to New Ebott, but after learning more than you should have, it was the only city where you could hide it.
It was the city where monsters and humans lived side by side, where both could be mobsters, thieves, dealers, or saints. Sometimes all in the same breath. New Ebott didn’t ask questions, though. It didn’t care who you were, just what you brought to the table, or what you could pay to keep off of it.
Of course, you had plans to stay out of trouble. That was until you met a golden tooth skeleton who won't leave you alone.

Summary
When you decided to stay in Ebbot City, you didn’t expect your life to intertwine with monsters, let alone fall in love with them. What began as simple friendship soon unfolds into something far deeper, as familiar faces begin arriving from unfamiliar worlds.
In a home filled with secrets, laughter, and quiet heartache, you’re drawn into a web of connection that transcends timelines. But love is never simple, and in a multiverse of infinite versions, learning who to trust, and how to hold it all together—might be your greatest challenge yet.
Because sometimes, the most powerful thing you can offer… is your heart.

Summary
He slid up in front of you, leaning down to ghost his fangs over your neck as he hummed a chuckle. “I think y’ did. A pretty present, all for me.”
You shuddered in anticipation as he lifted you into his arms, legs wrapping around his back. He kicked your door shut and headed straight for your bedroom, the only thought in your mind that this was exactly what you needed after such a shitty day.

Summary
The human was not gonna back down nor fight, and Sans, if possible, wanted to avoid a violent escalation of the situation as well. Because, despite the souls’ best efforts, his body had not yet recovered from his escape. Every single one of his bones ached, and he was almost certain that the cracks that already covered a majority of his skull had expanded.
However, the stalemate didn’t last long because, as it seemed, the human had an ace up their sleeve. The outline of a black soul manifested on their chest and, soon after, a bright red button with ‘RESET’ written on it appeared in front of them. Sans barely had the time to notice Killer’s eyes go wide and wonder why that was before the human pressed it.
Sans stumbled onto a snowy path with no grace, alone and lost in an unfamiliar frosted forest. Snowflakes slammed harshly against his bones. They looked so delicate and yet he could swear they left a thousand tiny cuts on him. It was torturous… and yet familiar.
That was the power of a human. No. That was the power of an anomaly.

Summary
After losing your dad at eighteen, you did the impossible. You became the legal guardian of your curious, chaos-prone little sibling, Frisk. Now at twenty-three, you've just about mastered the art of burnt pancakes, last-minute science projects, and saying "no" to whatever ridiculous idea Frisk has next.
Unfortunately, their latest obsession?
Mt. Ebott. The "cursed" mountain no one returns from.After weeks of relentless pleading and very dramatic puppy eyes, you finally agree to take them—just to look. With supervision, obviously. You’re responsible.
But the next thing you know?
You both fall down a hole and land in a world full of talking monsters, glowing flowers with a god complex, and… a pun-loving skeleton who might just be more than he seems?Well.
So much for a quiet weekend. -

Summary
We all know the trop, human falls underground and takes Frisk's place in the workings of the story. Or better yet, someone from our world falls down and takes the place of Frisk. But what happens when that person is deep in the fandom, a creator, someone who knows more than the shallow end of the fandom knowledge pool and instead of trying to hide what they know, they are upfront with Sans and all the monsters about what they know, they don't hold their punches and are determined to be kind and save all the monsters like they always try to when they write their own works.
Come on the journey of Nyx, a creator in the Undertale fandom with a big crush on our favorite skeleton that realizes sometimes wishes are not always what you hoped they would be.
WARNING: The reader tag is simply because Nyx's POV is done in second person, she is a fully fledged character with a look and a name and a personality.
Also I freely admit that this fic is a crack fic, and is honestly something I'm writing mostly for myself. I decided to share it with you lovely readers since some of my fans have wanted to see more of it. I have zero update schedule to speak of. -
Kingdomtale: before the kingdom tells its tale by melodic_melodies

Summary
So this is just gonna be a bunch of different chapters, with each chapter consisting of a backstory for a few of our favorite Kingdomtale (Undertale characters). Some will stick heavily to cannon and some will be fanmade by me. I made these backstories way before I actually wrote the Kingdomtale series, so I do apologize if they are written more weirdly or don’t read quite as good as the series itself.
Honestly, I enjoy looking back at my old work and seeing how far I’ve come. I think you’ll enjoy this fic because these backstories even if I don’t decide to mention them again in future projects. It’s just fun to have information that others may not, weather or not I being these backstories up again in future content 😉. Anyway, I hope you all enjoy the backstories for some of the cast of Kingdomtale 😁!
