Where we once were. {Undertale Reader Insert}

You're very unique. A monster soul with a trait. Human appearance. Made of part magic part physical material. Most people think you're a human but that's not true. You were once with monsters, being taught by Toriel to use fire magic and healing and even got taught teleportation from sans. This was all before monsters were pushed underground. Before the war. You were the only monster left above ground because of your appearance and once everyone was gone you didn't know where they went. You were on the surface for years until you were 16 years old when you heard there was a way to get back to your friend, the monsters. You traveled to Mt. Ebbot and fell down the massive hole that centered in the cave. This was going to be an interesting timeline...since Frisk was already in the underground ruins.

FWI THIS IS NOT AN XREADER
