Hwanung (Korean for the "Supreme Divine Regent") is an important figure in the mythological origins of Korea.
He plays a central role in the story of Dangun Wanggeom (단군왕검/檀君王儉), the legendary founder of Gojoseon, the first kingdom of Korea.
Along with his ministers of clouds, rain, and wind, he instituted laws and moral codes and taught the humans various arts, medicine, and agriculture.
Hwanung promised if they ate only his garlic and mugwort and stayed in the cave out of the sunlight for one hundred days he would make them human.
So Hwanung made her his wife and gave her a son called Dangun, a name which has two meanings: "Altar Prince" and sandalwood.
