Nebulous Duality

"The vicissitudes of life never came to hinder the utter serenity of my endless years." On the day of the Celestial's ascension, a fire burned down Fog Mount Temple, a tranquil residence on Mount Taixuan where she used to sojourn. Later, this sublime relique was found in ashes. No one knows what it's made of — it is silkier than the finest satin, yet tougher than the hardest metal; and when affected by external forces, the yin and yang on the relique start spinning, reflecting the forces back as a much more powerful counterstrike.
