Dae-Hyun was revered as a great warrior and field general for the provincial army of Hanju. On numerous occasions his battlefield strategies and sword skills kept villages within Hanju safe from thieving invaders.

And once again, Dae-Hyun was called back into service as Hanju’s borders were threatened. But this was the first time he had been activated for battle since the birth of his son Chin-Mae. Now five years old, Chin-Mae had just begun to understand his father’s accomplishments and teachings. The boy was even taking after his father’s delicate, yet fierce sword wielding techniques.

Duty called, however. Dae-Hyun prepared to lead his fellow soldiers into battle; hopefully to resolve the conflict and return the region to peace and prosperity.

It was common knowledge that the provincial troops had returned home years ago and Hanju was once again safe. Yet, Dae-Hyun never returned.

Eventually, Chin-Mae grew old; practicing medicine until his last dying breath. And, he never betrayed his father’s trust. The case remained closed. After his funeral, servants were cleaning out his office and one of them became curious about the case. He slowly removed it from the wall and set it upon Chin-Mae’s desk.
