司馬懿
Sima Yi
Profile
The pillar of Wei — and the architect of the Sima ascendancy that ultimately swallowed it. Serving four generations of Cao rulers, he crushed Meng Da’s revolt in eight days and pacified Liaodong. Against Zhuge Liang he waged patient attrition, refusing battle until his great rival died at Wuzhang Plains. Then, after a decade of feigned retirement, one coup at Gaopingling gave him the state; his grandson founded the Jin. The last man standing of the Three Kingdoms.

History vs. the novelHistoryvsNovel
To glorify Zhuge Liang, the novel demotes him to the dupe of the empty fort and the fleeing victim of a wooden statue. The historical Sima Yi carried Wei’s entire defense on his shoulders — the era’s finest strategist, and its most patient politician.
