Whur Ha-Rhang's Master and sole Master of Chun San Shin Gum or Divine Sword Dance of Mt Heaven and wielder of the Chung Sa Sword (Blue Snake Sword), she is known as the Swordswoman of Mt. Heaven. Its practitioners are required to master their emotions and keep them bound in icy calm. This emotionless state helps to master the potent han-ghi (cold energy) required to effectively use Chun San Shin Gum.
She was poisoned with Sub-Hyang-Han or Cold Leaf Fragrance that drained one of their internal energy and subsequently murdered.
