This drama portrays the life of the 19th king of Goguryeo,
Hwanwoong, who was sent from the heavens to make the world a better
place. He falls in love with Saeoh and gives her the joojak
necklace; however, Kajin becomes jealous since Saeoh has given
birth to Hwanwoong's son. She takes the baby and throws him off a
cliff. Saeoh, thinking that her son had died, is overcome with
grief and turns into the black joojak to destroy the world.
Hwanwoong is the only one who could stop her. Afterwards, Hwanwoong
returns to the Heavens and prophecizes that 2000 years later, the
true Joo Shin king will come to Earth. With the help of the four
gods, he will rebuild Joo Shin.
