Friendship is the true magic!
The Winx sneak into eerie Cloud Tower to get the ring back but they find the dangerous 'Crypt of the Magic Archive' - the most secret vault of Cloud Tower, where fairy are kept. But a mysterious voice guides Bloom, helping the Winx to escape.
At Alfea, Bloom is searching through the Alfea Library looking for information on Stella's ring. They are wondering why the ring is so important and learn that the ring has been in Stella's family forever.
Bloom goes back to the library to learn more about the Great Dragon. Miss Faragonda takes Bloom back to her office and tells her about the Dragon. Bloom learns that out of darkness, the Great Dragon emerged and created different worlds and spread life, light, and heat throughout the universe. Eventually, it settled down in Domino. When Bloom asks why Domino is cold now, Miss Faragonda tells her that it used to be beautiful before evil forces destroyed it.
Bloom leaves and journeys back to her room. They start to plan how to get the ring back. They decide to journey to Cloud Tower through the tunnels under the school.
At Cloud Tower, the Trix meditate to try to activate the ring, but it does not work. Knut tries to ask them what is happening, but Stormy sends him back to bed. Icy is disappointed she cannot find the ring's energy, and they find out the Dragon's Fire is not inside the ring. Pepe journeys out as Icy collapses.
In the tunnels, Bloom is leading them to Cloud Tower as Knut is cleaning up the witches' mess. The Trix journey into the woods and the Winx go above ground. They go up to the Trix's room. Tecna finds a weird doll and Musa finds a spiky bat. Stella finds the ring and puts in on. They start to leave, but Tecna cannot open the door to the tunnels. Bloom finds a door and decides to go in it. They end up in Cloud Tower's archives. Headmistress Griffin sees them and decides to send something bad to them. Tecna wants to leave but Bloom insists they stay so she can find more about herself. Bloom finds a book all about herself and even though Tecna warns her not to, Bloom opens the book.
They make a breach, and Flora conjures a spider-eater to take care of them. Bloom and Tecna speculate that there is more coming, but Stella dismisses the idea. The spider remains join to together to make a disgusting monster, so the Winx try to fly out of Cloud Tower. They reach a dead end and start attacking the monster. They defeat the monster and enter a room with tons of junk. A bake-o-monster comes out and Stella's magic backfires and the room catches on fire. Bloom, who fells responsible, hears Daphne and lets Daphne lead her out. The Winx follow Bloom and safely journey back to Alfea.
Back at Alfea, Griselda stops them and takes them to Faragonda's office. Faragonda learns about where they went last night, and Griselda suggests their powers are removed. Faragonda revokes their powers. In their room, Bloom decides that they need to get their powers back.

“Hey, look what I found! Kind of creepy, isn't it?”
“It's the Sword Ring! Welcome home little one, did you miss me?”
“There's something behind this door. I can just feel it, it's not a way out, it's something completely different!”
“Ha-ha! Did I scare you, girls? Why, this is just the beginning before long you'll regret your intrusion!”
“Bloom! Come, Bloom. Come with me, follow me, I, will lead you... to safety.”
“Wouldn't I? There are very few things I wouldn't do. And revoking your powers is NOT one of them!”
“And now we're totally powerless! For me, it's not so bad I've lived my whole life without powers. We've got to get them back! This is the only way we'll solve this mystery! I know how we can regain our powers, ha-ha! I just say the word 'Winx'!”
