The term 'Child of the Sun' is a reference to the INCA, an ancient South American civilization that flourished in the Andes Mountains from the 12th to 16th centuries. The INCA were known for their advanced engineering and agricultural techniques, as well as their religious beliefs which revolved around the worship of the sun. The INCA believed that their ruler, the Sapa INCA, was the 'Child of the Sun' and was descended from the sun god Inti.
