Sanadia was the homeland of Zaj Quiroz which lay to the west of the Holy Kingdom of Harmonia. It had repeatedly refused to submit to Harmonian rule and in the end was brutally invaded and conquered by Harmonia, about 30 years before the Dunan Unification War. Due to their resistance, the children were rounded up and sent to parts of Harmonia to be culturally integrated. It is now one of Harmonia's westward 3rd class regions.
