You climbed the famous Mt. Ebott to prove to a group of your friends that humans don't disappear when they go up the mountain. While walking around the peak, you trip over a root in the ground and fall forward, expecting to hit the ground. Instead, you were met with open air. As you fell down the large hole, you let out a shrill scream before hitting the ground and blacking out. 

When you wake up, you find yourself in the Underground where monsters had been banished to by the humans. 

You meet several monsters down in the Underground, some becoming friends and some becoming enemies. One particular monster though, has been making your heart flutter and your tongue get tied. 

Sans the skeleton. 

A new threat appears when a human that had been thought to be dead comes back and threatens you and the entire Underground. Will you be able to stop them or will you be used as a puppet and watch your friends die?

Maybe the only thing that can defeat LOVE is love...

Author's Note: this was my very first story so sorry if there's bad grammar or confusing scenes, enjoy my awful writing!

They sealed the monsters underground with a magic spell. After the war, the monsters retreated into the deepest part of the Underground, which would be called, "Home." - Note: In chapter one i NICKNAME frisk "Sam" Due to the fact you dont figure out their name until the end of pacifist so i had to put a nickname to make it easier to write and read.

L.O.V.E. (Yandere Fem Undertale x Child Reader) by Unidentified562

You live in Ebott City and you hear a story at the beginning of summer about the cursed mountain next to the city. You wanted to do something exciting for the summer and to you... What was more exciting than going to a mountain with a monster on it... Try falling into a hole into the kingdom of monsters where they accept human boys and men with open arms, but treat human girls and woman like the enemy due to them being sealed away by them.

Mine (Male!Chara X Reader X Sans) by xxAnnieSan

You've been doing the same True Pacifist / Pacifist Run over and over in a place called the "Underground". Though you like the Underground, you can't help but feel weary.. Every time you [SAVE] everyone, the World just..[RESETS]... And with that, you're back at the beginning again. You just want to go home... Why won't this "Underground" let you leave? ... Well, if you can't leave... Something 'new' should happen sooner or later, right..? (You hope that something exciting or different will happen in the Underground.) (You are filled with DETERMINATION.) --- ;) ~~~Disclaimer: I don't own those (MULTIPLE) pictures used in the Cover. I just mixed them up for a spicy cover. ( ͡° ͜ʖ ͡°) Mash-up covers are the best. ;') (I spent up to 3 hrs mixing stuff around + editing + adding light and shadows...*Dies*) If you have a problem with the Cover, I'll change it.

Y/N L/N's adventure in GenderVerse (REVAMPING) by Derek_ACreator

The Descent Begins YN LN, twenty years old and quietly unraveling, lives in the shadow of Mt. Ebott. A jagged peak that looms above the city like a forgotten god. Their days bleed into each other, marked by faded photographs, silent rooms, and a growing weight of solitude. On the morning everything changes, YN wakes to dust and ache, haunted by loss and memories that no longer feel like theirs. A package from a kind neighbor, a forced smile, a job stripped away without warning, small cracks in a day that already felt too fragile. They didn't know they would climb Mt. Ebott. They didn't plan to leave everything behind. And they didn't know the mountain would open up beneath them, pulling them into something ancient, strange, and irreversible. Beneath the surface lies a world of forgotten magic, fractured souls, and impossible beings-each encounter stitched with mystery, danger, and strange familiarity. Who will YN become in a world that reflects them like a mirror cracked down the middle? Who waits for them in the Underground? And can anyone-human or otherwise-truly escape what they carry with them? A fall begins the story. But the climb back out... will reshape everything. Read on, and descend.

Sans Can Never Forget | Sans Angst by Minksxy

Your favorite skeleton is back at it again... and again... agagaagaag Sans has had enough. Everyone is at the surface, holding their own jobs and lives. But... Sans can't ever let it fade from his mind. The dust. The cries. Watching the screen with Alphys as a child just rampaged in the underground. He is going to snap. He is mad. He is sad. He can never forget. Cover is NOT mine, find it online if you want ::Rights for the original concept and media 'Undertale' are all under the jurisdiction of Toby Fox. All other workings are done by me.::

Memory Lane [DISCONTINUED] by moonmuuse

(Sans x reader) !~**~! "How did you get down here anyway?" Sans asked, turning to me with a raised eyebrow. Do skeletons even have eyebrows? Huh. "I...don't know. I don't remember falling, I don't remember anything. Everything's just a blank page." I shrugged. "Where is this "Underground" anyway?" I asked, turning to him as well. "Mount Ebott. That's what humans named it and we kind of went with that. And I'm surprised you don't remember anything. Usually humans remember who they are and how they got here. Strange.." He said in a curious tone, more to himself than me. (Undertale x reader, what else do ya need to know? :3 )

ControlledTale by amilllionnames

(I DON'T OWN UNDERTALE. The only characters I own are Bailey and Creame.) All the monsters live happily in the underground: until one human ruins everything. Bailey Hill is a normal, 11 year old girl- until she trips, and falls into Mt.Ebott. Quick to befriend the monsters, Bailey is instantly loved by everyone. When monsters start mysteriously disappearing, Bailey is on the case. What she doesn't know, though, is that a small team, co-led by Undyne and Sans, are working as secret spies in the background. After hearing about the disappearances, Bailey thinks she can solve the mystery- but when Bailey has a shocking realization, she realizes that she might not be so innocent after all. ------------------------------------------- Changes: IMPORTANT: Frisk and Chara don't and never exist(ed) Monsters don't mind the underground, so Alphys never did the experiments. Still Relevant: Mettaton never left, and Napstablook is constantly being featured on his show The amalgamates don't exist since those monsters never fell down. Napstablook and Shyren are now younger than in-game, Napstablook - 12 and Shyren - 14. More on Napstablook- Since Mettaton never left, Napstablook is just shy. Everyone knows each other Alphys x Undyne- Already a couple Frisk and Chara don't and never exist(ed) ------------------------------------------- A note from Emma- Hi hoomans! I hope you enjoy this AU I came up with! Happy reading! 😊 10/4/2020: There IS a sequel coming soon! :D

A Different Kind of End - Book One - Reset by Toasty-Writer

Hatred is like an infection, if left to fester it only spreads and becomes worse, until there is little to no hope of return. Frisk had abandoned her life on the surface, she had no expected to survive the fall, even less so make friends with the monsters rumoured to live under the mountain. So what happens when she leaves and is all alone once again... What happens if she listens to the flowers advice..... Book one of A different kind of end. I do not own Undertale, or the characters used, simply the story concept.
