In "The Spy in the Shadows," while training with Avalon, Bloom laments over the fact that she is the only one who knows where the archive is and that she has had to keep it a secret all this time. Avalon makes her promise not to tell anyone, not even him, where it is. Later, due to an evil spell, a darkened Bloom heads to the archive with Lockette. She reveals the intention to give Darkar Alfea's piece of the Codex. She scours the place, throwing books around, and Concorda combats her.

Hippocampus reveals that the Codex is hidden in a book, and tries to fly away with it. It falls and everyone tries to reach for it. After another escape attempt by Hippocampus, Bloom acquires the Codex. The Winx arrive on the scene and try to fight her for it, leaving the archive in disarray, but Kerborg ultimately comes through the roof and takes the Codex to Darkar. Avalon then comes in and reverses the spell cast on Bloom. After everything is settled, Concorda commissions the Winx to clean up the mess that was left.

She answers that the ancient fairy form, Sirenix, will help but how to attain it has been lost for centuries. So, Faragonda has Bloom ask Daphne for its location as she was the last fairy to aqcuire it.

Helia is severely wounded by Darcy and is taken out of the archive by Flora and Krystal to be healed by the latter. But for Sky, it is much worse. While protecting Bloom from Icy's attack, he plunges towards the floor and hits on the head hard upon landing. The ruckus alerts Faragonda and Griselda to the scene.

In "The Sirenix Book," the archive can be seen in a flashback to Sky's fall. As the Winx talk, Musa says that finding the Sirenix Book will be difficult as there are countless books in the archive. In her dorm, Tecna is successful in accessing the archive with her phone. However, unbeknownst to Tecna, the Trix cast a spell on it. The Winx later meet in the magic archive to search for the book. The Trix's spell leads to the phone finding a cursed tome. Opening it results in Tecna turning into a book-seeking robot that wreaks havoc in the archive. The Winx transform into Believix fairies and battle her. After Bloom hits the phone with Fire Arrow, Tecna returns to her normal self. With the phone restored, the Winx finally locate the real Sirenix Book.

In "The Power of Harmonix," Tecna states she will have to search the archive for data on "Shimmering Shells on Andros".

In "Sirenix," the Winx head to the archive to search for information on the Source of Sirenix. They realize that to find the source, they must look inside themselves, and after consulting Bloom's Guardian of Sirenix, they conclude they must go to where their quest began: Lake Roccaluce.

In "Faraway Reflections," the Winx do a late-night search at the archive to find the Eye of Inspiration. After a thorough search, the Winx's results are inconclusive.
