Welcome reader !
You're about to read Horrortale : Rotten Apple, an Undertale AU fanfiction. Horrortale is an alternate universe I love very much. It's qualitative, with strong topics and strong characters.
I decided to write my own version of this universe, and more exactly a story that would englobed what happened before, during and after Horrortale. This is so a long story, in several parts. I hope you will like it !
This story is inspired by Sour-Apple Studios version of the story, of course, but also of some headcanons, some mine, some from the community. Don't forget to go check their art on Tumblr or Deviantart ! That's a very good stories and it's definitely a must-read !
Big warning : Horrortale is not a happy fluffy world. It's violent, it's gore and it's dark. There will be mention of eating humans, cutting organic stuff, power abuse, breach of trust, and many other subjects. I highly not recommend this story to underage readers and sensitive ones that could be hurt by some subjects that will be approach in this story.
Last little information : English is not my native language. I'm French :) Sorry if my English is weird or bad sometimes, I'm doing my best but, well, English lessons are not really good in French universities, so complain to them :') My DMs are opened if someone eventually want to correct the chapters before :D I'm always happy to talk to new people !
Well, let's go then :D I hope you will enjoy the story !

PROLOGUE : BEFORE THE END OF THE WORLD
Long ago, two races ruled other world : humans and monsters. One day, a war broke out between both species. After years of fighting and millions of deaths, monsters were defeated. The humans sealed them insinde of Mont Ebott with a magic spell, an impassable magic barrier. The only way to enter or exit it was to absorb a human or a monster soul, or, for breaking it definitely, to use the power of seven humans souls.
Years later, a human child named Chara, pushed by the hatred and the fear of humankind, fell by accident in what the monsters were now calling the Underground Kingdom. The child only found here compassion and happiness, along with a new family : King Asgore Dreemur, his wife, Toriel, and their son, Asriel. Quickly, the young prince and the human became like siblings. But one day, the human child fell very ill, and, after days of agony, died. In their last moments, Chara asked Asriel to take their body outside the barrier, because they wanted to see one last time the flowers of their village. The night that followed, Asriel obeyed and traveled through the barrier thanks to Chara soul. When the humans saw him, they thought he had killed the child and attacked him without a warning. The prince didn't fought back. He quietly took back Chara's body inside the mountain, before he himself dusted in the middle of the royal garden.
The King and the Queen lost two children in one night. Blinded by guilt and sadness, King Asgore ordored that every human who fell in the Underground die and that their soul had to be collected, so that, with seven of them, he could break the Barrier get revenge for his son's murder. Queen Toriel, shocked by all the hate spreading across her people, ran away, no where to be seen ever again. During two centuries, six humans souls were collected in the Mountain. Everyone was waiting for the seventh and last to come.
And one day, it happened. But this child was not like the others. They never hurt a single monster. They never wanted to fight. Intead, they restored confidence to those who needed it the most, they make friends on the road and, in the end, everyone thought that, maybe, they could succeed where others didn't : free monster kind peacefully. However, to leave the Underground, they had to fight Asgore and make a choice : leave the King take their soul… Or give theirs.
Against all odds, the kid showed no mercy and took Asgore's soul without a regret. Then, they betrayed everyone by destroying the six souls. When Undyne came back to the palace, all she found was a pile of dust. The souls were gone. Asgore was dead. The child was gone.
At least, that's what the official story said. One tiny skeleton named Sans never trusted the version of Captain Undyne. He knew that something much darker was following the child. But how to prove it without passing himself for their partner in crimes ? He was sure the human would come back. He was always coming back. The sooner would be the better. The kid showed him that there was still a reason to hope, and he was rooting for him.
Yeah, for once, just for once, Sans didn't give up. And this is where our story started.
