The spirit dragon Byeong-Ho is an ancient spirit, one of the four spirit guardians. Associated with water and the ocean, her home is the city of Unknown though she has largely not been in residence. Instead, she can be found in Unknown at the Imperial Waterfall Palace. The only exception to her distance from her home was when the exiled son of the Park House, Dae-Jung, briefly snuck back into Daeyang along with the Unknown.
