On my coming-of-age ceremony, I came to the family sanctuary. What appeared in front of me was a bracelet-style cross tied with black thread. "This is a family heirloom of my Huan family. Every ten generations it chooses an owner. This time it chose you. You are its owner. You have your own mission. It will take you where you should go. I hope you don't embarrass my Huan family." It was just the last voice I heard in this world.
