Winx Club: The Secret of the Lost Kingdom.The story begins on a snowy, foggy day. In the isolated snow peaks, a looming castle casts dark, imminent shadows on the ground. Six cloaked figures appear, whom are none other than the Winx Club. Bloom and her friends are on a search for Bloom's birth parents, King Oritel and Queen Miriam, with Bloom's belief that they are still alive. The girls are on their way to find Hagen, a blacksmith who forged the Sword of King Oritel, a magical sword with immense power that can never be separated from its rightful master, in hopes that he can sense the sword's power and trace it to Bloom's parents. The girls successfully sneak into Hagen's castle after an easy victory over his robot guards, and come face-to-face with Hagen, who believes they are intruders. Faragonda then arrives to ease Hagen, them being old friends. They return to Alfea to discuss the matter. Bloom begs Hagen for his help in sensing the sword's power, but he admits that he is unfortunately unable to. Spirits plummeted, 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 out of shame and sadness. This is easy as most of the Alfea third-year fairies are graduating to become Guardian Fairies, after having earned their Enchantix powers. Due to Bloom's powers being incomplete, she is compelled to stay behind as she watches her friends graduate. Consoling herself with her pet rabbit Kiko and a new kitty friend named Purr, Sky comes to comfort her, encouraging her to continue her quest despite Hagen's words. 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. The next morning, Bloom leaves for Earth to stay with her adoptive parents for the time-being. Though she seems happy, Mike can tell that Bloom is uncomfortable living on Earth, to which Vanessa agrees that she belongs more in the Magical Dimension. That night, Bloom has a dream about Daphne, who tells her that there is still hope; their parents are still alive and offers Bloom her strength. Daphne also informs her about the Book of Fate, a tome their father kept that tells the entire history of Domino, and its location. In the morning, Bloom is surprised to see all of her friends, plus the boys, there to celebrate her 18th birthday. Not only are her spirits lifted, Bloom shares her plan and they all agree to help her, reminding her of their everlasting friendship. The restoration of Bloom's hope triggers the Sword of King Oritel, deep within the dark Obsidian Circle, the center of all Evil forces. Its glow troubles the spiritual forms of the three Ancestral Witches, the culprits behind the destruction of Domino. They employ Obsidian's Keeper, Mandragora, to root out the cause of the sword's reactivation and snuff it out like a candle, additionally imbuing Mandragora with a fraction of their dark powers...
