You fell into the underground after tripping on a branch and so happened to fall into a place like this. When you had explored, you came across Asriel and some others. This place was filled with monsters, and you so desperately wanted to go home. With a heavy heart and a sigh, you walk off into the next area. You were just trying to explore a mountain after all, you weren't expecting to fall into some hidden underwlrld. These monsters... You always thought these were just made up stories and myths. Now you can see that you were wrong. Very wrong. As your thoughts swelled up, it was interrupted by someone coming up to you.

“Howdy, it is I, The Charismatic Chara!”
