Word has been released that monsters now roamed the surface, and you can't help but feel slightly skeptical. 

You had been told since childhood that monsters were vile and repulsive creatures who wanted nothing more but human blood pouring from the palm of their hand. You didn't know what to think of the monster race, but majority of the human race did. 

The tension between monsters and human kind was sickening. 

People had told you to stay away from monsters at all costs. But that'll be a bit difficult when two skeleton brothers move in next door to you. 

And why bother lying?

You can't deny that one of them has stuck on your mind.

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.

Moon Light - Undertale fanfiction (FriskXSans-not the main plot tho) by Ombre0

Most of the humans were not pleased with the monster arrival, but since Mont Ebbot was a bit far from the city and that no one ever goes their (for most part of the population at least) they allow the monsters to rebuild their society on it and around it as long that they keep their self far away from the city. With their magic it only took a few days for everyone to be set .It was a new start for monster kind, now they would only need to make their relation with the humans better. Everything was for the best; well it was until the little human that had free the monster got her secret exposed. --- -A/N- -Undertale and all of it's characters belong to Toby Fox -My first language is not english -Frisk is a girl in this story -I don't know when I will be abel to update but I will do my best to not be to slow -Don't esitate to give me some feedback it's my first fanfic :) ---

Sacrifices (Undertale FanFic) [COMPLETED] by Brynwyth

Frisk has freed the monsters of the Underground. Finally, monster kind is allowed to return to the surface. It's been 3 years since then. Yet the monsters still struggle to find their place within the world. Most accept the monsters, but there are those who wish nothing more than the complete annihilation of monster kind. Merely sealing them away is not enough. As ambassador for the monsters, it is Frisk's responsibility to fight for everyone's right to live on the surface. But at the same time, an internal battle rages on within her. Not only that, her relationship with Sans is strained. Trust is not so easily regained after the slaughter of one's beloved, despite it all being erased. Or was it really? The memories are still there. *I have lost interest to complete pre story and post story parts. Please enjoy the main story and the extra tidbits.* Chinese Version: http://fav.me/db7h2kg DISCLAIMER: I do not own Undertale. TobyFox is the creator and owner. Cover art does not belong to me.

What Went Wrong? by AngelOfTheDead80

~'Disclaimer: This story has a lot of profanity and covers some very very intense or touchy subjects that may disturb some readers. You have been warned.'~ ((Unedited)) After Chara fell into the Underground, they met Asriel a monster inhabitant of the Underground. Soon after that, Chara joins a new family, but their ambition to keep everyone happy goes a little overboard and Chara is flung into a reality of destruction and hopeless wonder. Then many long years later they meet the beloved Frisk, who fell into the Underground, similar to themselves. Eventually everything Chara thought they knew correctly is turned upside down and they as a person are changed forever. ~'The game Undertale belongs to Toby Fox and some of the dialogue is ripped straight from the game itself, too.'~
