The Nine Celestial Fraternity was named as such because nine powerful celestial patriarch orthodox clans ruled over the hundreds and thousands of celestial clans in its divine realm.
Yuan Ji and Ling Feiyue were surprised that they were from the Nine Celestial Fraternity. It was because although the Nine Celestial Fraternity had bordered the Desolate Celestial Fraternity but the cultivators from both fraternities had rarely ever met except when they were taking the Empyrean Warrior Labyrinth Trial where cultivators from all over the Celestial Realm would then encounter each other and the encounter was often unpleasant.
Moreover in order to reach the Desolate Celestial Fraternity, a vast desert to the World End's Mountains and the equally treacherous Moon Demon Forest had to be traversed. Also the cultivators from the Nine Celestial Fraternity would then emerge in the unfriendly territory of the unorthodox fraternity.
