That ended when the Wizards of the Black Circle, whose goal was to rule the Earth by controlling the forces of nature, arrived. They created a powerful spell which made them immune to fairy magic, which allowed them to catch the fairies, steal their wings, and drain the magic from them. The Wizards of the Black Circle began fairy hunting, and one by one, the fairies were defeated while the power in their wings made the Wizards stronger.
Morgana, Queen of the Terrestrial Fairies, faced the Wizards of the Black Circle, but was defeated, and not even the Major Fairies, the supreme guardians of nature's forces, could escape the Wizards of the Black Circle. All hunted Earth Fairies were eventually sealed away in their own realm of Tir Nan Og; the last of whom was Morgana, the Earth Fairy High Queen.
The Wizards had won, and magic on Earth disappeared. The people on Earth forgot about fairies, who became nothing more than legendary figures they read about in fairy tales. The Earth had nobody to protect it anymore, and the human world, with no protection, slipped into chaos, war and intolerance.
However, one last Earth Fairy had escaped the Wizards of the Black Circle, Roxy, who was still only a baby when the Wizards of the Black Circle captured her mother, the Earth Fairy Queen Morgana. Roxy was saved because she was still too young to reveal her powers, which prevented the Wizards from finding her for many years.
Centuries later, they were freed from their imprisonment by the Winx and began a campaign for revenge against humanity (much to the disapproval of the Winx).
After days of conflict, during which the Major Fairies of Earth Diana and Aurora intervened, the Fairy Queen Morgana decided to give a fair trial to the Wizards but nearly fell in a trap laid by Ogron. After Nabu sacrificed his life to close the trap set by Ogron, Nebula overthrew Morgana and went to the Omega Dimension to seek revenge against the Wizards. The Warrior Fairies were almost defeated, but in the end the Winx and Nebula by using a Believix Convergence, overpowered and defeated, as well as frozen solid, the Wizards, and Nebula repented.
Morgana then made a speech, announcing that their new life had begun and that they owed much to the courage and sacrifice of the Winx girls, and remembered Nabu's sacrifice so that they could live. She then asked the Earth Fairies, for Nabu and for all of them, to honour, respect, and defend life and to go to the human world, to release their magic and make it a better place. Morgana then abdicated the throne and named Nebula as the new Queen of the Earth Fairies and went to live with her daughter Roxy and her husband Klaus in Gardenia.
What happened afterward is unknown, but it is presumed that they are working to fully restore Earth's belief in magic and are doing their best to make the world a better place to live by releasing their magic throughout the planet.
It is assumed that all Earth Fairies, like the fairies from the entire Magic Dimension, go through some sort of magic training to master their powers and become full-fledged fairies, and that all Earth Fairies that already appeared in the series did so before the Wizards of the Black Circle started hunting them.
In "Mythix," the Winx and Eldora travel to Tir Nan Og in search of magical artifacts that will grant them access to the Legendarium World. Upon their arrival, they come across Nebula, who has turned her castle into a college for fairies.
The Earth Fairies were then given some encouragement from Bloom after she chased off Lazuli and her friend. When Selina appeared to try and take Bloom's Dragon Flame, the Earth Fairies remained brave and sought to defend Bloom but they were not strong enough against Selina who chased them way after she blasted them with magic.

- The Earth Fairies' having their wings plucked is similar to how the Fairy Clan died in The Seven Deadly Sins.
- Roxy is still the future Queen of the Earth Fairies, as Nebula is merely serving as her regent.
