At the dawn of the primordial era, Heaven and Earth took shape, dark and yellow. The Battle of Zhuolu set the sky ablaze with blood and fire, and finally ended with the victory of Yan and Huang and the defeat of Chiyou.
As defeat loomed, the surviving tribal warriors and die-hard followers under Chiyou, carrying scattered fragments of their demon lord's bloodline and undying battle spirits, followed an unseen call into a dark abyss. Over millions of years, the descendants trapped in the Demon Abyss were repeatedly steeped in Chiyou's legacy and the abyss's overwhelming malice. They developed demonic markings and transformed into a demon race driven by an instinct to kill. They lay in wait through the eternal night, passing down the shame of defeat from generation to generation and etching their obsession with returning to the human world and overturning Heaven and Earth into every inch of their bones and blood.
The bloodlines of the ancient gods who won that world-shaking war did not fade with time. They took root across the land of Jiuzhou, prospering under the name of noble clans, passing down their ancient traditions and guarding the order of the human world.
