This time we won't be following this tale with Frisk but a with a different main character, a girl named Aria and her cousin, Eric. One day she visits her Uncle who lives in a cabin on the side of Mt. Ebott. She goes hiking with Eric because of her unsatiable curiosity which often times gets her into trouble. They come across a giant chasm where they both stumble and fall in. There they'll discover the world of undertale where they'll make new friends, enemies and fight to save the monsters trapped in this cavern. Hopefully they have enough determination and kindness in their hearts to get through all of this and to keep all of their promises. (Disclaimer: the characters all except for any I may create do not belong to me. They belong to Toby Fox and all the other creators of the game Undertale. Please don't sue me.)

Falling into a world, where monsters only care about killing all humans, Frisk has to try and escape. But with barely any friends, and with each death comes a new flower growing on them, they find that this wish is much more difficult than they thought. But, what happens when their determination becomes to much for only one person to hold? (This is a Frisk x Chara fanfic, the are both agender and will be referred to with they/them pronouns. This is using the Flowerfell AU, which is a combination of two different AUs; Flowertale: which is when every time Frisk dies, a golden flower blooms somewhere on their body, and Underfell: which is that all the monsters are more set on killing Frisk instead of mercy, and it's much harder to survive, and Flowey is actually kind and helps Frisk. The plot is created by me, but credit goes to Toby Fox for creating Undertale and whoever created the Flowerfell AU. Cover art is not mine and credit goes to the respective artist.)

"Don't you know how to greet a new pal?" "Kids like you should be burning in hell." "Dirty Brother Killer." "Sans! I'm not any of those! I didn't hurt anyone!" But the skeleton wouldn't listen. Eye glowing blue, he raised his hand, taking your body with it. "Sans! Please!" An evil, bone-chilling laugh echoed through the room. "You never change Y/N." And with that, you shot back down to the ground... Warning! Dark Themes such as Depression, Social Anxiety, and Suicide ahead! (Obviously there is some spoilers ahead for both genocide and pacifist route.)

Undertale is a game with multiple endings, everything that you do redefines the whole world around you. But... What If...? What if Sans found you first before Toriel? What if Flowey was possessed by someone else? What if Papyrus was evil? What if Undyne never met Alphys? What if Asgore had died before the events of the game? What if... I was to tell you what would happen if those events had occurred? WARNING: MASSIVE SPOILERS I do not own anything related to Undertale.
