Eun Ha-Seol

Eun Ha-Seol is a mysterious girl who came across Jin Mu-Won after being attacked by a unknown assalient. After recuperating from her injuries, she gradually began to open to Mu-Won while rebuilding her strength and took it upon herself to defend him when the Northern Heavenly Sect was under attack before being rescued by her master, the Witch of the Witch Night Seo Geum-Hyang. After bargaining for Mu-Won's life in exchange for her completing her training and lose her memories of him despite being her mortal enemy, she tearfully bid him farewell and left him alone in the ruins of his home and place of captivity. In the years since, Ha-Seol had inherited the title of Possessor of the White Night from her master as a member of the Silent Night though also only retaining a faint echo of her time with Mu-Mon.
