The New Joseon, ruled by the one and only God, has Narin as their national religion. On a peaceful day on October 3rd in Joseon, the descendant of God made his appearance to the world. He leads a legion of iron-clad machines and takes over Joseon, thus opening a new dynasty by the name of New Joseon. The original social class, which consisted of the Noble, the Middle, the Common, and the Low is now gone. Now, the people of New Joseon are divided into four new classes: the Ruby, the Lapis, the Amber, and the Shadow.

The Ruby are the royals, the ones who rule the country. The Lapis are the aristocrats, the former nobles. The Amber are the mechanical iron-clad men, a new species in New Joseon, created from the rituals of the Red. The Shadow are the ones who are ruled, the subjects, very much like slaves in slightly better conditions.

Our protagonist, Saegyeol was an ordinary Shadow until she was chosen to become a Lapis. On the Day of the Oracle, when she was chosen by God, her father died in vain, not knowing the reason why.
