The Supreme Emperor's thoughts were initially without form or shadow. Dissatisfied with the heavens, he sought to play a game against them. Thus, he gathered substance to decide the fate of Jingwei.
Destiny was predetermined, playing with the white pieces. Those who are ignorant, stubbornly pursue their path, resigning to fate, willingly becoming the White Piece.
The Supreme Emperor played black, to maintain balance. Those who are wise, follow him, defying destiny, all following the Shadow.
