While Major Fairies all have realms of their own that they rule and where they have followers, they all submit to the rule of the Fairy Queen of Tir Nan Og, who is the Queen of all Earth Fairies and to whom they have to obey, as shown by the loyalty of Aurora and Diana towards Morgana during the Great Fairy Revenge after being freed by the Winx, with the possible exception of Sibylla who has to remain neutral in all situations since she is the Major Fairy of Justice and cannot take sides, even if it means disobeying the Fairy Queen. Nebula also has been shown to be rebellious sometimes, due to her thirst of revenge against the Wizards of the Black Circle who captured her, leading her to disobey and even overthrow Morgana to fulfill her revenge.
