long ago, two raises ruled the earth. Humans, and Monsters. the Monsters had magics and special abilities. and the humans where very powerful and had special souls. but one day, the humans declared war on the Monsters in fear that they would over throw them with their magic. and locked them away underground, the story has been tossed around for so long, no one really believed it anymore.

you are (Y/N). you ran away to mount. Ebbot trying to escape you're evil mother and step father. they would hit you and call you names, and made you feel worthless. and after a while, you believed it was all true. you ran away in hopes to end it all. but litle do you know, you're 'end' would be your beginning.
