Shan Wuling (The Ravages of Time)

Daughter of the Shan merchant clan, and betrothed (later wife) of Sima Yi. Regarded as Sima Yi's perfect match, Shan Wuling possesses genius-level cunnings and ruthlessness, as well as a drive to gain profits for her clan's business with little respect for ethical standards. Thus, similar to Sima Yi, she holds the post of the clan's strategist and the advisor-commander of its private assassin squad, the Defeated Generals, and is respected as such by the clan elders.
