The Ruler of Darkness

Born beneath the ominous fate of the Heavenly Killing Star, destined to bring bloodshed wherever he walked, he refused to draw his sword, fearing the calamity it would bring upon the world. Though he knew the future, he chose to avert his eyes. But the price of his indifference was devastating. His clan was annihilated. His family was slaughtered. Only at death's door did he finally grasp the truth. Heaven does not punish the wicked. Karma does not exist. Justice is nothing more than a fantasy the weak cling to. The moment that realization dawned upon him, a forbidden scripture appeared before his eyes...

"Sutra of Vanquishing Darkness and Rending the Heavens."

A heaven-defying scripture born from the accumulated grudges of mankind, heaven, and earth.

"If heaven refuses to pass judgment... then I shall do it myself."

Having embraced the darkness, he returned as the Ruler of Darkness, vowing to punish every sin and bring down the sword of judgment upon this rotten world.
