Kindred of the East: Crimson Empires
Ghost, Kui the Gravekeeper Specter
Little is known of this maleficent Yin spirit.
It seems he was roused when the rock quarry dug too deeply and he has since began to gather an army to bring the end of the Empress, his most potent Yin rival. He employs Yang spirits (banes) towards this end as well, and displays a shocking degree of cunning for those corrupted.
The Wu is still piecing together his history. It is unknown at this time if he was a contemporary of the Empress or simply covets her wealth. Either way, a battle is inevitable and will spark off very, very soon.
