Incense coils through the Celestial Master Hall, yet it cannot dispel the oppressive gloom. The current Celestial Master, Zhang Xuan Ling, has a head of white hair and a lean, clean-cut face, but his eyes are like a deep pool reflecting the turning stars and the joys and sorrows of the world. He gazes at the deepening dusk beyond the hall and lets out a soft sigh. At the edge of the horizon, a faint trace of darkness steadily eats away at the sunset glow. It is a sign that the Heavenly Dao has fallen out of balance and yin and yang have been thrown into chaos.
