Gegengol, ruled by a tribe known as the Hirasu tribe, had a tribal chief who claimed blood relationship with the Family of Gold and shared common ancestry with the Great Khan Gu Erduo of the Golden Tent. The chieftain held the title of the "Grand Sun King" because of this.
At present, the Grand Sun King has no lack of progenies, amongst them, Agula was barely noticeable amidst the myriads of contests for the King's regard. His mother was a female slave who had been forced into coition during one of the King's many drunken binges.
