Shadow Village (그림자 마을, Geulimja Ma-eul) is the name for the slums in Ga Guk. It was first visited by the emperor himself while chasing a boy thief. He witnessed many residents who are badly in need of the government's help. While talking with Woon, Yi Won became exasperated about the insult brought about by the innocent boy against the current emperor and Imperial Family of Ga Guk. In turn, Yi Won ordered the Bi Yeong Pal Mu to burn the village down.
