Dragonblood: Starting Contract Time Dragon

Before those "Dragonborn" called "Dragon Controllers" came to the Fertile Continent, the Magic Empire was the most powerful civilization on the continent. They are proficient in nature, alchemy, magic, casting... With human power, they can even lift majestic cities into the sky and hang them high in the sky. However, it turns out that the dragon's power is unprecedented. The dragon's scales are innately immune to most magic. Swords and armor cannot block the dragon's flames, and those giant cities suspended in the air are always shrouded in the shadow of the dragon's wings. The Dragonborn destroyed the Magic Empire and created the Fertile Continent's first unified dynasty - the True Dragon Dynasty. They have ruled this continent for a full 5,700 years. … In the True Dragon Dynasty, only dragon masters can be crowned "Dragon Lords" and inherit titles and territories. Rod, the lord's son in Dierheid Territory, who failed to become a dragon master, was deprived of his inheritance rights and exiled from the family territory.
