Pralaya: The dragon lord

Five hundred years ago, among the existence of demi humans, humans and demons, the dragons stood at the pinnacle of power. Their magical capabilities, which surpassed all the humans and demons, still remained a mystery. The dragon lord Pralaya, possessed the greatest might of all, killing thousands in moments with ease. But as all things, his reign of power ended when the strongest warrior of the human race used BRAHMASTRA against him, a weapon feared to utterly annihilate any existence. The mighty beast died in front of the divine weapon. But, as destiny has it, the dragon lord’s soul reincarnated inside a human boy’s body.

Will the lord act as the feared Pralaya and seek revenge?

Or will his existence as a human change him?
