"The Dragon's Claim" tells the story of the final years of the Yan Dynasty, when Xuanyuan, leader of the rebel bloodlines, rose to power in the Hundred Thousand Mountains. He shattered the fateful lie that "the orthodox bloodline alone is supreme" and, driven by the ideal that "the bloodline belongs to all the people," led his forces north to seize the Jianghuai dragon vein and challenge Zhao Jin, the Yan emperor whose harsh rule had cost him the people's loyalty.
This struggle for the dragon's authority, spanning north and south, was not only a clash between the spiritual powers of the orthodox and rebel bloodlines, but also a contest between the old order and a new world. Xuanyuan united the worthy and rallied the people, taking "You" as his name to reshape the order of the dragon veins. Zhao Jin clung to the "orthodox Fire Virtue" until his eventual downfall, proving at last the ultimate law: "The dragon vein's power rests with the people's hearts."
