Won Sul Rang

A master swordsman from Jushin, who was once a subordinate of Munsu. However, when Jushin fell he began serving Aji Tae, growing Yang Gwi Bi, a plant with narcotic properties, to ship to the west in exchange for weaponry. His weapon, Saruhyondo, is a sword with a blade forged from his killing "ki," or killing intent. (Source: Wikipedia)
