"Promise me one thing- just one thing only." Frisk nodded vigorously. "No one can know about this whole reset thing. Not Papyrus, not Asgore, not anyone. It would basically bring this world to the point of falling to pieces at our feet. If we weren't trapped between time and space already, very few of us wouldn't be able to handle that knowledge, and could drive those who couldn't to the edge. So, please. I'm begging you. When you reach the End, when you get us out of here for the umpteenth time, I don't care if you reset or not. Just don't tell anyone about it, and... Please don't go homicidal again, okay?" Frisk smiled meekly, and nodded. "I can do that. And don't worry about the reset." They gave Sans a small hug. "After that whole thing with Chara, there won't be any more." And with the final word, they opened the door to leave; before exiting they paused. "See you later."

After Frisk goes missing, Caitlin, Frisk's twin sister goes looking for her in the the last place she saw her. MT Ebott, the mountain of dark legends, she finds a necklace that belonged to Frisk on the ground. Just like Frisk, Caitlin tripped and fell into the Underground. Caitlin finds things she never knew existed.

Once there was a girl with no heart and once there was a boy with one. Once there was a giant factory which bought hearts and transformed them into sandal heels. Once there was an eagle and once there was a mechanic. Once there was love and once there was a story about it.

Book 3 of my Undertale Soul series is finally up! Yay!!

In the Undertale universe, a different human child falls down into the underground. Even though she is very young she will have to find her way home or stay there forever. ----- Big thanks to my friend from school who helped me out a bit.

Let those who have been silent and hidden for many years rise from the shadows of myth.
