Winx Club. The Secret of the Lost Kingdom.

Bloom and her friends Stella, Flora, Musa, Tecna, and Aisha (or Layla in some dubs) search for Bloom's biological parents, King Oritel and Queen Marion.
They seek help from Hagen, the blacksmith who forged Oritel's mighty sword. Having infiltrated Hagen's castle, they find themselves uninvited guests. Faragonda, Hagen's old friend, intervenes, and they return to Alfea empty-handed.
Despite Bloom's plea for help, Hagen admits that he can't help, and Bloom feels guilty for her friends' futile efforts.
She runs away in tears to avoid meeting them.
Most of Alfea's third-year fairies, including the Winx (except Bloom), graduate and become guardian fairies of their home planets after gaining their Enchantix powers.
Bloom, whose powers have not yet manifested, remains at Alfea under the care of Sky, who comforts her and encourages her to continue her search despite Hagen's disappointment.
Their touching moment is interrupted by the sudden appearance of a mysterious girl.
The next day, Bloom goes to Earth to visit her adoptive parents.
Despite her apparent contentment, Mike and Vanessa see that she is uncomfortable on Earth and understand that her true place is in the Magic Dimension.
That night, Bloom dreams of her sister Daphne, who gives her hope by telling her that their parents are still alive and shares important information about the Book of Fates.
