The Black Ring

There's a black ring that our family held. This ring passes through our parents to us, and to keep this tradition there's should be one person keeping it. That person was me, I'm Alya Serion from the Serion family, one of the richest and famous family in our land. I've been chosen to keep the black ring, but then "What exactly the importance of this ring? Why do they have to pass it to another family member?" I ask in my mind, until one day i figured out something.
