Dragon Master

Each 20 years, a new generation of dragon riders rise, with one "dragonborn" leading it. However, Leo had not expected what he was going to face. Hard decisions, crossroads and a war to end.
-----------------------------------------
At the age of 15 you get to attend a ceremony that is held every 20 years called "The Choosing Ceremony" , and Leo Andrius, did not expect to be the dragonborn of his generation, and follow his great grandfather's footsteps. Despite the fact that he is chosen, his family has fallen apart ever since he's lost his elder brother: Lancelot. For a few days, he'd been meeting him in the Spirit Realm, and he was warned of the war, and Leo hadn't given up on his desire- Kill the beast that killed his brother.
