Heavenly Authority was rumored to be the oldest organization of the Heaven Race, much older than any Imperial Lineage. It was the strongest organization in the Tenth World, powerful beyond imagination despite its few members.
Ordinary Grand Emperors from the Heaven Race couldn't join this organization. Only Grand Emperors with ten Heaven's Wills and up were eligible. This organization was the symbol of the Heaven Race. All of their members would want to join after reaching a certain power level.
