Friendship is the true Magic!
As the Winx prepare for Daphne and Thoren's wedding, they soon discover that Selina freed Acheron. Acheron banishes the Trix to the Legendarium and then removes all magic from the Magic Dimension - except for the dragon flame!
In the classroom of History of Magic, the Winx worries about the the object they should trade with Rumpelstiltskin in exchange for the Legendarium Key since going to the Alfea Underfloors was not much of a help to them. Stella then begins improvising objects, but ends up messing with the Winx. Eldora enters the classroom and gives them the Infinity Box to contain anything magical. Daphne, who is out of herself, hums the Wedding March. Bloom asks if she is alright and the teacher replies she is getting married, and the wedding is today.
At Cloud Tower, Selina immediately hides the spark of the Dragon Flame that she stole from Bloom last time. The Trix gets mad at her and asks why she forfeited. Selina explains that she stole the fire from Bloom, surprising the Trix, to free Acheron from the Legendarium. She does so and Acheron is freed. The Trix thinks he is on their side, but says he will begin his reign, double-crossing Selina as well. The Trix fights him, giving Selina enough time to escape. Acheron then uses his magic to trap the Trix in the empty page of the Legendarium. Selina sees in the book that the Trix are already trapped. She hides in Griffin's office to contact Bloom and warn her about freed Acheron. He comes in and uses a spell to strip everyone of their magic, removing the flight spell the Trix put upon Cloud Tower.
At Domino, Daphne is shocked that she does not have magic, even to create an energy bubble. Eldora explains to the Winx that they still have a spark of Bloom's inextinguishable Dragon Flame. Bloom remembers Selina's words about Acheron's freedom and the danger the entire Magic Dimension might face. She apologizes to Daphne that the wedding will have to wait, so they should leave and Daphne lets them go. The Winx transforms and goes to Cloud Tower.
At Cloud Tower, Acheron tries to get the Legendarium from Selina. She accidentally falls from Cloud Tower, but is saved by Bloom. She promises the Winx to explain everything after the Winx saves the college for witches. The Winx converges their magic to create a protective ring to slow down the fall. Acheron comes out and releases the Great Lizard Spirit, a trio of dragon heads that shoots lightning bolts from their mouths against the Winx. Bloom realizes that Acheron is commanding them to do so. To stop them, she fights Acheron, but fails. She then tells Selina that the only way to defeat him is to give him to Rumpelstiltskin, exchange him for the key and lock the Legendarium.
Bloom enters the Legendarium World while Acheron chases her to Rumpelstiltskin's cottage. There, the two fight. Bloom makes Acheron go to the land and be attacked by the dwarf's land traps, but Acheron already knows about this. Bloom, who is hidden behind a bush conjures the Infinity Box to suck in Acheron. She takes the box and trades it for the Legendarium Key. Rumpelstiltskin happily goes in his cottage but gets scared when the Trix appears behind Bloom to let her linger in the Legendarium World much more to make her overstay there, to trap her in there with them and to torture her forever.
