Guo Jia (courtesy name Fengxiao) is the fourth of the Eight Enigmas—a select group of military masterminds trained by the legendary strategist Sima Hui. He earned the nickname "King of Strategic Decisions" because of his uncanny ability to anticipate nearly every possible outcome and factor them into his plans.
Along with his close friend Jia Xu (the Third Enigma), Guo Jia follows what's known as the "Darkness ideology"—the belief that ruthless, sometimes brutal action is the truest path to lasting peace and stability. This philosophy made him invaluable to Cao Cao as a trusted advisor and earned him the reputation as Cao Cao's "darkness," but it also created friction with his senior, Xun Yu (the Second Enigma), who didn't share the same worldview.
