The Shadow of the Pajeowi: Analyzing Ai Da Gan in Kingdom: Ashin of the North

When Netflix’s acclaimed historical-zombie thriller series Kingdom expanded its universe with the 2021 special episode Kingdom: Ashin of the North, it traded the claustrophobic palace corridors of Joseon for the harsh, windswept northern borderlands. Amidst a narrative brimming with political betrayal, trauma, and the genesis of the resurrection plant, one character commands the screen with chilling magnetism: Ai Da Gan.

Portrayed by versatile award-winning actor Koo Kyo-hwan, Ai Da Gan is much more than a standard villain. He is a primary catalyst for the entire Kingdom tragedy, representing the brutal collision between imperial ambition, marginalized tribes, and unstoppable vengeance.

Who is Ai Da Gan?

Ai Da Gan is the fierce and imposing chieftain of the Pajeowi tribe, a powerful nomadic faction of the Jurchen people living near the border of Ming China and Joseon. In a world defined by survival of the fittest, Ai Da Gan has risen through sheer military might, tactical cunning, and an unyielding presence that strikes fear across the northern frontiers.

Unlike the polished, bureaucratic officials of the Joseon court, Ai Da Gan is visceral and raw. Wrapped in heavy furs and leather, bearing the battle scars of a warrior king, he commands absolute loyalty from his men. Yet, behind his intimidating exterior lies a leader who is acutely aware of the delicate geopolitical tightrope his tribe walks between the collapsing Ming dynasty and the expanding Joseon kingdom.

The Catalyst of Catastrophe: The Pajeowi Massacre

Ai Da Gan’s most consequential—and devastating—action in the narrative is his brutal destruction of the Seongjeoyain Jurchen village, the home of young Ashin.

The tragedy does not stem from unprovoked malice, but rather from sophisticated political manipulation:

• The Setup: Joseon military commander Min Chi-rok needs to cover up a diplomatic incident involving missing soldiers. To appease the aggressive Pajeowi tribe and prevent a full-scale war, he manipulates information.
• The Deception: Tricked into believing that a group of 15 Jurchen hunters were massacred by the Seongjeoyain villagers (who are ethnically Jurchen but loyal to Joseon), Ai Da Gan demands blood.
• The Bloodbath: Believing he is enacting righteous tribal justice, Ai Da Gan leads a merciless raid, wiping out Ashin’s entire village and subjecting her family to unimaginable horrors.

This single act of destruction serves as the narrative bedrock of the entire franchise. By crushing Ashin’s world, Ai Da Gan unknowingly births the monster that will eventually bring Joseon to its knees.

Koo Kyo-hwan’s Masterclass in Nuanced Villainy

What makes Ai Da Gan memorable is not just what he does, but how Koo Kyo-hwan plays him. In lesser hands, a character tasked with executing a horrific village massacre could easily devolve into a flat, cartoonish tyrant.

Instead, Koo infuses Ai Da Gan with unexpected dimensions:

• Pragmatic Leadership: He is driven by a fierce duty to protect and elevate his people, viewing Joseon’s hypocrisy with deep suspicion.
• Unpredictable Charisma: He shifts seamlessly from cold calculation to explosive, terrifying rage.
• Human Vulnerability: Even in his brutality, there is a sense that he, too, is a pawn in a much larger geopolitical chess game orchestrated by empires that view border tribes as disposable.

Director Kim Seong-hun noted that Koo’s interpretation successfully elevated a conventional antagonist into a complex figure of tragedy and intimidation.

The End of the Chieftain and His Legacy

Ai Da Gan’s journey ultimately meets a grim, poetic end. Years after the massacre, a hardened, traumatized Ashin (played by Jun Ji-hyun) returns to exact her meticulous revenge. Armed with the resurrection plant and unmatched archery skills, Ashin dismantles everything Ai Da Gan has built, culminating in his death by an arrow straight to the head.

While Ai Da Gan falls, his death does not bring peace. By the time Ashin claims her vengeance, the resurrection plant has already escaped into the wild, infecting Joseon and setting into motion the zombie outbreaks witnessed in seasons 1 and 2 of the main series.

Conclusion

In Kingdom: Ashin of the North, Ai Da Gan stands as a masterclass in antagonist writing. He is neither a pure monster nor an innocent victim; he is a product of a violent era, shaped by borders, blood, and betrayal. Through Koo Kyo-hwan’s magnetic portrayal, Ai Da Gan remains one of the most striking figures in K-drama history—a man who thought he was securing his tribe’s future, only to sign the death warrant of an entire dynasty.
