Deung Ha Bul Myung (등하불뮹, The Base of the Lantern is Dark) is the rebel army established by Yi Hwi which aims to reclaim the throne of Ga Guk after being driven away by Yoon Yeon Lee who is now the Empress Dowager and her son Yi Won as the current emperor.
During the coup at the Jin Hee Palace, the cast away Crown Prince Jin Yeon and his subordinate Yi Jeok are adopted by Wol Young Hwa, under the order of Seon Woo Seo In, despite the two children having a rough encounter with her. Ten years after, Yi Hwi is now the leader and Yi Jeok as his co-leader of Deung Ha Bul Myung which they built at Bi Hwa Rim. Also, Yi Hwi disguises as a young gisaeng at Yu Hyang Ru while Yi Jeok is a musician. While performing missions, Yi Hwi usually takes up the role of Crimson Moon and his members also put on masks which then become a symbol that is admired and supported by people who are helped by the rebel army.
