The Winx Club begin their third and final year at Alfea. As fairies, the six best friends learn of their full-fledged fairy form, Enchantix, that can only be achieved when a fairy rescues someone from his or her own home planet and shows great courage, bravery, self-sacrifice, and compassion in doing so. Meanwhile, in the Omega Dimension, the Trix find and release a powerful and vengeful wizard named Valtor, who has a tragic connection to Bloom, as he was directly involved in the destruction of Bloom's home world, Domino, seventeen years ago alongside the three Ancient Witches. They choose to forge an alliance and plan to invade several areas in the realm of Magix and seek vengeance on those who imprisoned them by stealing their exceptionally strong, magical and mystical treasures and immeasurable power sources of each realm.
