Dragon King's Abused

Once upon a time, there was a huge kingdom in the middle of the world. It was a land like no other and was enriched with tremendous powers and prosperity. The kingdom used to hold extraordinary powers of fire and was the most feared and ferocious realm of that time, because it was the land of nothing but warm-blooded dragons. And the empire was known as the land of Dragonborns. Yes, it was one such land where everyone was born with dragon's blood while each male of every status of the hierarchy was destined to get birth with their own dragon as the other half of their soul. It was like the same soul in two different bodies, among which one was more like human and the other was the beastly creature which reflected the heart and the mind of the former more than in their human shapes. And of course, like every other kingdom, the land of the Dragonborns was ruled by the most powerful Dragon King ever, together with his most lethal beast. During that time this kingdom was the strongest and the unshakable monarchy among all. But who could have thought that a kingdom like such would fall only to burn into ashes in just one day? Who could have thought that the very same fire which they owned would be the reason for their destruction completely? Who could have thought that the name of such an empire would be erased from the pages of history as if it never existed? The land of Dragonborns did cease to exist over just one night leaving only one soul behind to fight throughout his life for the rights. Yes, a little boy and his young dragon were yet to learn how to survive alone in the middle of nowhere, without anyone to show them how.
