The next morning, Bloom is surprised to see all of her friends at her house to celebrate her eighteenth birthday. She offers Bloom her strength through her mask, and also informs her about the Book of Fate - a tome their father kept that tells the entire history of Domino, and its location. The same night, Bloom has a dream about Daphne, who tells her that there is still hope their parents are still alive. Although she seems happy, Mike and Vanessa see that Bloom is uncomfortable living on Earth, and that she belongs more in the Magical Dimension. The next day, Bloom leaves for Earth to stay with her adoptive parents. They share a tender moment until a mysterious girl arrives, forcing Sky to leave in a hurry, although he promises Bloom that he will explain everything later. Sky comes to comfort her, encouraging her to continue her quest despite Hagen's words.
Due to Bloom's powers being incomplete, she is compelled to stay behind as she watches her friends graduate. Most of the third-year fairies at Alfea, including the Winx (sans Bloom), graduate and become guardian fairies of their home planets, after having earned their Enchantix powers. Bloom feels guilty for the effort her friends have put in when it had been hopeless the whole time, and runs off in tears to avoid facing them. Bloom begs Hagen for help, but he admits that he is unable to aid her. Soon, Faragonda, an old friend of Hagen's, arrives and they return to Alfea to discuss the matter. The girls successfully sneak into Hagen's castle but when they encounter Hagen, he believes they are intruders. The girls track down Hagen, a blacksmith who forged the powerful sword of Oritel, a magical sword that can never be separated from its rightful master, in hopes that he can trace the sword's power to Bloom's parents. Bloom and her friends, Flora, Stella, Musa, Aisha and Tecna, are on a search for Bloom's missing birth parents, King Oritel and Queen Marion, who Bloom believes are still alive.
