Summary
They said no one who climbed Mount Ebott ever came back, but you weren’t “no one.” When Y/N falls into the Underground, they awaken a story that’s been repeating for years… one of monsters, souls, and a lazy ass skeleton who’s seen it all before. But this time, something’s different. The resets don’t feel the same. The laughter doesn’t sound the same. And Sans, the lazy, pun-loving sentry, starts to wonder if maybe this is the one timeline worth breaking the rules for.
In a world where everything resets, what happens when someone finally makes him want to stay?

Summary
The Multiverse isn't as unreachable as one might think. Sometimes, all it takes is one aware person to tip the scales for another to find out about it. But when one isn't ready for it, returning to their own world is relieving and best for the psyche.
Humanity's thirst for knowledge is near insatiable. How far would they be willing to go to learn more about their new magical coinhabitants on the surface? How far would they go if they could weaponise their magic?

Summary
Long ago, deep in the quiet woods of the Underground, Grillby sought only solitude. He never expected to find a fallen human woman-wounded, frightened, and far from home. Against his better judgment, he took her in. At first, it was duty that kept her hidden and safe from the Royal Guard. But when her laughter began to fill the spaces between his silences, protection became something deeper.
When word of her existence spread, Grillby made a dangerous choice: he marked her under his protection, binding her fate to his flame. Their bond grew-slowly, tenderly-but like the flowers she loved, her life bloomed briefly. And then it ended, leaving only memories and ash.
Centuries later, on the Surface, Grillby runs a quiet bar and tells himself he’s content. That is, until a new regular walks through the door - a woman with the same gentle voice, the same curious eyes. There’s something achingly familiar about her, like a dream half-remembered. His flame stirs, warmer than it’s been in ages.
But can love reignite across lifetimes? -

Summary
Your roommate is… weird.
He likes spaghetti and glitter (mixed together, preferably), has a penchant for speaking about himself in the third person, sets up puzzles in the hallway every weekend, and he has begrudgingly befriended your dog.
Also, he's kind of a superhero.

Summary

Summary
It's really late when you get home from work, only to come face to face with your empty fridge. Barely anything is open at this hour, just a small shop that mostly sells booze, but you'll have to make due.
The cashier is a big, rude, skeleton. Which wouldn't have been a problem if you weren't so tired and hungry, but it really ticks you off. Leaving the store in a fit of rage, your stomach is still growling.
Fine.
You go back to apologise and buy some cheap cookies for dinner. Hopefully that's the last time you'll see his stupid face.

Summary
You fell.
Which honestly sucks ass.
You had been feeling weird, in your chest, for a while now.
Not sure how you ended up in a world of monsters but you do know one thing.
Your chest is pulling you towards something. And the closer you get, the more whole you feel.
You just hope you don't have to keep dying to get what your SOUL desires.

Summary
The real world can be a cruel place.
There is no Dark World. No Lightners. No Darkners. No prophecy to set forth a chain of events to whisk away tears and make everything right. No chain of coincidence to magically and miraculously mend broken bonds and build friendships anew.
In the Real World, there is only Kris—lifelong loser and social outcast. Amidst a broken home, an unrequited childhood crush, and the myriad other struggles of adolescence, they want nothing more than to live a Regular life—to be normal—to blend in.
Yet, try as they might, the universe has other things in mind…
Updated weekly.

Summary
Frisk has faced danger and death many more times than any child should ever have to, but they aren't out of the woods yet. Being the first human in who-knows-how-long able to use magic has shoved them back in the spotlight. And just when their life was settling down into whatever counts as "normal" for the town of Ebott's Wake, where monsters sell ice cream and the gym teacher thinks anime is real.
It's nothing they haven't had to deal with before at this point, but that doesn't mean it's going to be easy, even with Papyrus taking over as Ambassador and the Finest scientific minds in the town working on a way to help Chara. After all, the first fallen human climbed Mt. Ebott for a reason, and it wasn't a very happy one.
And now, that reason knows about Chara too.Series
