At the dawn of chaos, the universe was split into three spheres: the celestial realm, the mortal sphere, and the infernal domain. From the celestial realm a spirit seed descended to aid ordinary folk. Yet this seed continually soaked up the world's darkness and mercilessly harmed all living beings. In the end, Sen Luo, ruler of the celestial realm, sacrificed himself to seal the seed. Consequently, Shangqing Xianmen—home of the celestial realm—gradually weakened and slipped into obscurity in forgotten history. A thousand years later, the remnants of Shangqing Xianmen began to surface one after another as legends spread across distant lands. Every major sect fought fiercely for the treasures hidden within those ruins, vying for control over the powerful relics.
