Baek Ah was a member of Bi Yeong Pal Mu.


Baek Ah was quite formal and reserved. As a member of the King's guard, he was loyal to King Jin Won and obedient to his superior, Heuk Rang. Moreover, Baek Ah appeared to possess leadership skills, as he was shown to head a handful of soldiers during missions during multiple occasions,[1][2][3] typically during Heuk Rang's absence or as a co-leader. Baek Ah was also a skilled spy, who once tailed then-minister Seo In Seon Woo to Yu Hyang Ru without being sensed[4] despite Seon Woo's keen sense to his surroundings.[5]

Baek Ah seemed to be close with his subordinate Baek Ju, who was usually seen with him during Bi Yeong Pal Mu missions. Furthermore, though he was apparently accustomed to his captain's rage in the event of a failure, Baek Ah sometimes shrugged it off and calmly anticipated a possible beratement afterwards.[2] Nevertheless, Baek Ah took his responsibility seriously that, despite his usual level-headedness and calmness even during battles, he was not prone to bouts of anger, most especially if the scenario concerned the immediate safety of the king.[3]


Compact Heist Arc[]

One midnight, Baek Ah and Baek Ju tail the Crimson Moon and Yi Jeok for stealing the compact in the chief state councilor's residence. While in pursuit, the Crimson Moon battles his companion Baek Ju and throws a smoke bomb into them, letting him escape. Heuk Rang then arrives at the place and throws a poisoned dagger at the Crimson Moon and wounds him. He and Baek Ju are then ordered to search for him.[6]

Rebel Army Suppression: Setting in Motion[]

As Jin Won orders for the eradication of the rebel army, Baek Ah tails Left Minister Seon Woo as he heads to Yu Hyang Ru before sundown. Though Baek Ah reasons that the minister is single and heading to a gisaeng house is not unnatural nor illegal, the guard still finds the highly abstinent minister suspicious, deciding to look further into the matter.[4]

Rebel Army Suppression: Execution[]

Baek Ah's unit at Yu Hyang Ru

Bi Yeong Pal Mu split into two units in order to eradicate the rebel army. Baek Ah is assigned to the lead the unit that razed Yu Hyang Ru, the rebel army's center of finance and contact. They utilized a surprise ambush at the gisaeng house, setting the place on fire. He orders his forces to surround the house and capture anyone who is caught escaping the fire. He also allows his subordinates to kill anyone who resists them. Later, he orders his archers to open fire, resulting to the deaths of countless gisaeng and servants, including Yu Hyang Ru's owner, Wol Young Hwa.[1]

Minister Retrieval Arc[]

Baek Ah takes part in cornering the Crimson Moon at the king's chambers by using the ex-Left Minister Seo In Seon Woo. After coming face-to-face with the rebels, Heuk Rang wafts through the smoke bomb that Gil Mu Jin released. To his dismay, the captain faces the rest of the Bi Yeong Pal Mu outside the king's chambers waiting for their ambush. They all wonder where the rebels have disappeared to.[7]

Baek Ah faces the Crimson Moon

Eventually, as the captain and his subordinates escape the flooded tunnel caused by the rebels, Heuk Rang angrily orders to locate the rebels at once. After turning the lights on, the rebels are found. Baek Ah instructs Baek Ju to chase after the rebel who carries the ex-minister, but she reasons out that, as the rebels split up, all of them appear to be carrying the ex-minister. In any case, Heuk Rang orders the two of them to merely chase all three of them. Baek Ah and a handful of soldiers chase and attack the Crimson Moon, but he escapes after covering himself with the "ex-minister", which turns out to be a dummy. Baek Ah orders his men to search all over the place, sighing how the captain shall be mad once again after his squad fails to catch the Crimson Moon.[2]

Crimson Moon Rebellion[]

Baek Ah among the casualties of the rebel army's revolt

Following the imprisonment of Yoo Ja Gyeom, the palace is shaken by explosions set off throughout the area. Baek Sa, Baek Ah, and the head servant arrive at the king's quarters to inform him that the rebels have entered the palace. Baek Sa and Baek Ah leave the safety of the king to his head servant.[8] Later, Baek Ah leads a small platoon of palace guards and arrives at the bridal quarters to look for Jin Won, unaware that he is dead. They fire arrows at the quarters, injuring Dan Ah and Hwi. Though a soldier notices Dan Ah and identifies her as the councilor's daughter, Baek Ah instructs him to kill her if she gets in their way while finding the king. Despite his existing and newly-inflicted wounds, Hwi kills all the palace guards, including Baek Ah.[9]
