A young member of Heiyue's upper management who has supported the Lu family— the most powerful within the syndicate—for several years. He is a master of Gekka, one of the three great Eastern schools of martial arts, and is known to some as the 'White Orchid Dragon,' but beyond that, he also shows a keen intellect and cunning in everything he does. Cao is a pragmatist who tends to look at everything in terms of cost vs. reward. However, he does place a certain degree of importance on human relationships as well, often using his connections to their maximum potential in order to achieve his objectives. As president of Heiyue Trading, Ltd., his public-facing role gives him a lot of control over the material interests of western Zemuria, which he has recently made use of to assist the next-in-line elder of the Lu family, Fan Lu, during an incident that occurred recently in Langport. Thanks to all this, he has been highly successful at carving out a secure foothold for himself within Heiyue.
