Previously banished to the Omega Dimension, the Trix are able to escape with Valtor, an evil sorcerer partially responsible for the destruction of Bloom's home planet, Domino. They choose to cooperate and plan to invade several areas in the realm of Magix and seek vengeance on those who imprisoned them by stealing their exceptionally strong, powerful, magical and mystical treasures and immeasurable power sources of each realm. With their newly strong and powerful Enchantix powers, Flora, Stella, Layla, Tecna, and Musa are able to use strong, incredible power and can miniaturize themselves. Bloom, however, cannot miniaturize herself due to the fact that her Enchantix is not complete. The Winx begin their third and final year at Alfea, learning about their unique Enchantix transformations, acquired by selflessly sacrificing themselves for someone from their home world (or even everyone from every world, in what ends up being Tecna's case) and showing great courage in doing so. With no one from her home planet to save, Bloom must acquire her Enchantix form and tremendous power on Pyros, the island of dragons. She also learns more about her home world of Domino, as well as the truth about where her birth parents, Oritel and Marion, are. She is the keeper of dragon flame.
