Spoiler warning: The following sections contain detailed plot points, character fates, and major ending reveals for the series finale of The East Palace.

The True Mastermind Behind the Curse

While the series initially leads viewers to believe that a vengeful pond spirit is the primary source of the royal family's suffering, the finale delivers a shocking twist regarding the true antagonist. The mastermind behind the decades-old curse is revealed to be none other than Saeng-gang's grandmother, who is also the biological mother of King Ju-sang, played by Cho Seung-woo. Driven by ruthless ambition, she orchestrated the brutal murders of several princes who stood ahead of her son in the line of succession. To mask her political assassinations, she cleverly used the legend of the palace curse as a convenient and terrifying cover. [S1][S2][S3][S4][S5][S6]

The King's Dark Secret

The tragedy of the royal family is further compounded by the revelation of King Ju-sang's complicity. The finale confirms that the king was fully aware of his mother's murderous actions. However, rather than stopping her and seeking justice for his fallen relatives, he chose to turn a blind eye. This calculated silence allowed him to secure his own ascent to the throne, building his reign on a foundation of blood and dark secrets. [S1][S2][S3][S4][S5][S6]

The Crown Prince's Descent into Darkness

The generational trauma and bloodshed inevitably infect the next generation. The current Crown Prince eventually uncovers the horrifying truth about how his father rose to power. Instead of breaking the cycle of violence, the Crown Prince adopts his grandmother's ruthless tactics. He begins systematically killing his own brothers to eliminate any threats and secure his position as the future king. [S1][S2][S3][S4][S5][S6]

A Supernatural Siege

Realizing the monster his son has become, King Ju-sang is forced to take drastic action. In a tragic confrontation, the king ultimately kills the Crown Prince himself to put an end to the fratricide. However, this act of violence only escalates the supernatural threat. Fueled by immense resentment and anger, the deceased Crown Prince returns as a powerful Ak-gwi, an evil spirit. This formidable entity then raises and leads an entire army of spirits in a devastating assault against the palace, setting the stage for the final battle. [S1][S2][S3][S4][S5][S6]

Gu-cheon's Ultimate Sacrifice

As chaos engulfs the East Palace, Gu-cheon is forced to make a desperate and dangerous choice to defeat the Ak-gwi and save Saeng-gang. He enters into a perilous pact with the Primordial Gwi-mae. In a heartbreaking sacrifice, Gu-cheon agrees to become an Ak-gwi himself in order to obtain the only weapon capable of destroying the Crown Prince's corrupted spirit. [S1][S2][S3][S4][S5][S6]

The Final Battle and Escape

Armed with this newfound, dark power, Gu-cheon successfully destroys the Crown Prince's soul, ending the immediate threat to the palace. However, the toll of the battle and his transformation leaves him on the brink of death. In his final moments in the Realm of Gwi, Gu-cheon selflessly transfers his remaining Yang energy to Saeng-gang. This vital transfer of energy is what allows her to safely escape the spirit realm and return to the world of the living. [S1][S2][S3][S4][S5][S6]

Saeng-gang's True Identity

Alongside the supernatural resolutions, the finale also resolves the lingering mysteries surrounding Saeng-gang. It is revealed that she is secretly the king's daughter, adding a profound layer of personal tragedy to her involvement in uncovering the palace's dark history. Despite the defeat of the primary supernatural threats, Saeng-gang continues to hear spirits, indicating that her connection to the supernatural world is permanent. [S1][S2][S3][S4][S5][S6]

The Aftermath of the Siege

The conclusion of the series sees King Ju-sang finally confronting the consequences of his reign. During the climax, he openly acknowledges his past sins and offers a sincere apology to the spirits for the immense suffering caused under his rule. This act of contrition plays a crucial role in weakening the Crown Prince's Ak-gwi. Following the battle, King Ju-sang continues to rule the kingdom, but he is now heavily burdened by the weight of his past actions and the destruction of his family. [S1][S2][S3][S4][S5][S6]

A Tethered Fate

As for the heroes, the ending provides a bittersweet resolution. Although Gu-cheon initially appears to perish after his sacrifice, it is revealed that he survives the ordeal. He ultimately leaves the East Palace alongside Saeng-gang, suggesting that their partnership will continue outside the palace walls. However, his survival comes with a lingering cost. The final scenes reveal that an invisible chain remains permanently attached to Gu-cheon's hand, forever tethering him to the spirit realm and leaving his ultimate fate intertwined with the supernatural forces he fought so hard to defeat.
