Friendship is the true magic!
As the fairies of Alfea celebrate Faragonda's one hundredth anniversary, the Trix take over Cloud Tower, teaming up with Selina, a new witch with a very powerful book. Her first target: Pixie Village.
It's Daphne's first day as the new History of Magic teacher. At Cloud Tower, a witch named Selina wields an evil book known as the Legendarium.
A new school year begins at Alfea. All students including the Winx return to Alfea. Bloom and Daphne arrives at Alfea excitedly, but Daphne is still nervous of becoming the History of Magic teacher. Bloom comes to her room happily where she meets her friends, Musa, Aisha, Flora and Tecna. Then, they see several students come out from Stella's room with unique outfits and one of them dropped Stella's boutique card (Stella's couture). The Winx go up to Stella's room to find it out for themselves. Stella is so happy to meet her friends and explains about her new boutique. Thanks to Stella's creativity, they are dressed smartly for their new school year. Suddenly, Griselda comes to the Winx's room and Stella quickly hides her secret boutique in her room. Griselda is expecting them for Miss Faragonda's speech at the History of Magic classroom.In the History of Magic classroom, Faragonda honorably introduces Daphne as the History of Magic teacher in front of her students. The Winx and the other students clapped their hands to welcome their new teacher. A moment later, the pixies come to surprise Faragonda for her one hundredth anniversary as headmistress at Alfea. The Winx are really happy to meet their bonded pixies. Griselda is shocked by the news the pixies told everyone as it was meant to be a secret. The pixies invite Faragonda to celebrate outside Alfea as their presents are awaiting for her. Outside Alfea, the pixies use their special magic to hold a special party for Faragonda. The party is celebrated happily by the fairies at Alfea College. Meanwhile at Cloud Tower, Griffin introduces herself and welcomes the young witches to Cloud Tower. Then, she asks her new students to show their powers. A young witch named Selina, who is from Earth is the first one who introduces herself to everybody at Cloud Tower. Grffin demands to see her powers and she took a book from her belts, The Legendarium. The Legendarium is a book that can bring legends and tales to life. Selina shows Griffin on how the Legendarium works by reviving legendary trolls, the Gloomy Wood Trolls, which are beasts that is locked under the Pixie Village. She summons them by reading the book out loud and awakening them. Not a moment too soon, the trolls attack Pixie Village from underground and causes chaos to happen. The Winx transform to help the pixies. They fight against the trolls with the help of the pixies. Griffin doubted the powers of the book and she demands to see it herself. She uses her magic to see the incident and when she sees that chaos is happening at Pixie Village, she asks Selina to stop. Selina stops by ending the tales, creating new legends in the book. Right after she stops, the pixies that were attacked disappear along with the trolls. The Winx's bonded pixies wonder where their friends are, and ask Bloom to detect them. When Bloom does, she said that she cannot detect them as like the pixies no longer exist in the Magic Dimension. The pixies get saddened by their friends' disappearances and stay with the Winx at Alfea.
Meanwhile, Griffin dismisses Selina and continues her speech, until her speech is interrupted. The glass windows break open, the Trix appear and tell Griffin that they are going to take over the school. A fight breaks out between the Trix and Griffin, with the Trix turning Griffin into a crow.It leaves while the Trix announce to the students that they are in charge. They make a costume change and say the witches that if the witches will support the Trix, the witches will rule the Magic Dimension. Listening that the witches will be the rulers with no obstacles around, the witches of the Cloud Tower happily agree and support the Trix. The Trix then raise Cloud Tower off the ground. Icy dismisses the witches except Selina who, in exchange for her letting them use her Legendarium, will help make her more powerful. And Selina happily agrees with them.
On the way returning to Alfea, the Winx see a falling crow and Aisha uses her Morphix power to help it. The crow tries to tell the Winx something, but they cannot understand anything because they could not speak "crowese". Bloom suggests using Roxy's help, since she could understand any animal's language.
