Man-Wol was the daughter of hunters but after a fateful series of encounters with a Bear Spirit known as Hakja, she forewent the use of weapons and instead devoted herself to the arts of medicine and poison crafting.
According to some of her stories, Man-Wol created some sort of elixir of immortality and is still alive out there somewhere.
During their venture to the Spirit World, Unknown was able to confirm that Man-Wol is still alive and serving the court of the Spirit Emperor.
