Illea was built on the ashes of the former United States, which was destroyed after losing World War III to China. The resulting country (the American State of China) rebuffed an invasion from Russia which led the entire area of North America to be led by one man: George Illea. George declared himself king and Illea was born. Illea spans from the bottom tip of Central America all the way up to the northernmost parts of Canada. It is cut up into 18 provinces, some named after their old names (ex. Carolina is named after South and North Carolina) and some are more difficult to figure out.
After the war, a society was formed putting people in castes. Castes are what separates the different kinds of people and your social ranking in the world. Illea is divided up into 8 different castes. Once you are born into your caste, you are destined to your caste and the only way you can move is through marriage or through the selection.
Quick Summary
Pretty much there will be 18 girls competing for the Prince’s hand in marriage through The Selection. Think about this as a royal version of The Bachelor
