Chetamja

When a devastating Jurchen raid claims the lives of his entire family, a young man named Gwiyeong is left with nothing but an all-consuming desire for retribution. He swears a solemn oath to track down and eliminate every last warrior responsible for the massacre. Driven by this relentless fury, he hones his combat abilities to a razor's edge, transforming his grief into lethal proficiency on the battlefield. His extraordinary martial prowess does not go unnoticed. King Sejong himself recognizes the young fighter's potential and extends a remarkable invitation: to join the Chetamja, an elite cadre of covert operatives who serve as the monarch’s unseen eyes and ears across the northern territories. Accepting this role means stepping out of the light and into a world of clandestine warfare. Now bound to a brotherhood of skilled agents, Gwiyeong must learn to channel his deeply personal vendetta into something far greater. Alongside his new comrades, he works to forge his burning vengeance into a disciplined blade of duty, defending the kingdom of Joseon from the shadows against the very enemies who destroyed his life.
