Shadows of the Borderlands: Decoding Ai Da Gan and His Role 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 palace intrigue of Joseon for the bleak, biting cold of the northern frontier. At the heart of this harrowing origin story is not just Ashin herself, but a volatile geopolitical landscape shaped by fear, betrayal, and violence.

Among the figures driving this tension is Ai Da Gan, the fearsome chieftain whose actions inadvertently unleash hell upon the kingdom. Portrayed with chilling charisma by versatile actor Koo Kyo-hwan, Ai Da Gan remains one of the most memorable catalysts in the entire Kingdom saga.

Who is Ai Da Gan?

Ai Da Gan is introduced as the ruthless leader of the Pajeowi (United Jurchen Tribe), a powerful group dwelling near the Amnok River border of Joseon. Operating in a precarious grey zone between loyalty and aggression, the Pajeowi command heavy respect and fear.

• The Face of Power: Played by Koo Kyo-hwan, Ai Da Gan cuts an imposing figure. Unlike stereotypical, one-dimensional villains, Koo imbues the character with a quiet intensity, physical unpredictability, and a commanding presence that makes his threat palpable even during moments of calm.
• Political Leverage: As the head of a formidable tribe, Ai Da Gan’s movements are closely monitored by Joseon military authorities, who view the growing strength of the Pajeowi as a direct threat to national security.

The Catalyst of Tragedy: Manipulation and Massacre

The core tragedy of Ashin of the North hinges on a deadly game of political chess orchestrated by Joseon military commander Min Chi-rok. Desperate to conceal a sensitive border incident and prevent an all-out war, Min exploits the existing cultural and political divides between Joseon and the Jurchen tribes.

“For the Pajeowi, honor and blood are inextricably linked—a code that leaves them dangerously susceptible to external manipulation.”

Fooled by fabricated evidence planted by Min Chi-rok, Ai Da Gan is led to believe that a group of 15 missing Jurchen people were murdered by the inhabitants of a local Seongjeoyain village—the very village where young Ashin and her family live.

Driven by tribal duty and a fierce code of vengeance, Ai Da Gan leads the Pajeowi in a merciless raid. The resulting massacre is swift, brutal, and total, wiping out Ashin’s community and setting off a chain reaction of generational trauma that fuels the rest of the narrative.

Retribution: The Fall of Ai Da Gan

While Ai Da Gan acts as an instrument of destruction in the first half of the special, he ultimately becomes a target of absolute devastation. Years after the massacre, an adult Ashin (played by Gianna Jun) returns to exact a calculated, cold-blooded revenge against everyone who played a part in her village’s destruction.

Despite his fearsome reputation as a warlord, Ai Da Gan’s arc comes to a definitive and visceral end when he is cornered and killed by Ashin—who dispatches him with a swift arrow to the head. His death underscores the central theme of the episode: human cruelty and political scapegoating always breed their own monsters.

Why Ai Da Gan Matters to the Kingdom Universe

Though his screen time is limited to a single feature-length special, Ai Da Gan serves a vital narrative function:

• Humanizing the Conflict: He bridges the gap between faceless geopolitical threats and grounded human conflict, showing how easily empires manipulate regional groups for self-preservation.
• Fueling Ashin’s Descent: Without Ai Da Gan executing the raid under false pretenses, Ashin’s transformation into a vengeful, resurrection plant-wielding mastermind would never have taken place.

Through Koo Kyo-hwan’s compelling performance, Ai Da Gan transcends being a simple antagonist, embedding himself deeply into the dark, haunting lore of the Kingdom universe.
