Winx club magic adventure (2010)

Reunited with her birth parents, Oritel and Marion, Bloom discovers what it is like to live as a princess of Domino. Adding to her joy at being with her parents is the upcoming Princess Ball, which Sky has asked Bloom to attend with him. But Bloom's happiness is short lived when Sky is forbidden by his own father to escort her. Meanwhile, the evil Ancestral Witches who had once destroyed Domino join forces with the Trix - Icy, Darcy, and Stormy - to erase all positive magic from the Magic Dimension. To reverse the effects of the Witches' devastating reign of darkness, the Winx and the Specialists must travel to the cursed city of Avram and come face to face with the Trix and the Ancestral Witches. Only by defeating the witches can the Winx restore the positive magic in the entire dimension and regain their own powers.
