You've fallen and you can't get up... (#lifealert reference XD) You dont know where you are. A man made of flames, a couple small children, a child goat, a couple skeletons, and a mother goat happen to be playing frisbee in the field of buttercups you've fallen into.
You're stuck here, but it's not all that bad. You have friends, and a new family. Your old one treated you like a Cinderella, with no happy ending in sight, and you're glad you fell down. Then one day... something changed.

"How did you get down here anyway?" Sans asked, turning to me with a raised eyebrow. Do skeletons even have eyebrows? Huh. "I...don't know. I don't remember falling, I don't remember anything. Everything's just a blank page." I shrugged. "Where is this "Underground" anyway?" I asked, turning to him as well.
"Mount Ebott. That's what humans named it and we kind of went with that. And I'm surprised you don't remember anything. Usually humans remember who they are and how they got here. Strange.." He said in a curious tone, more to himself than me.
