In this season, the Winx Club fairies go back to Alfea college for their second year. A new fairy named Aisha joins the team after escaping from Lord Darkar, the enemy of the season. Lord Darkar wants to find the four pieces of something called the Codex. The Codex can open the realm of Realix, where a large amount of power can be found. The Trix, now expelled from Cloudtower and stuck in the Fortress of Light, team up with Darkar. During the season, the Winx girls and Specialists try and fail to protect the four pieces of the Codex. Late in the season, Bloom gets turned evil by Darkar and exposes Alfea's piece of the Codex. During the season, the Winx also earn something called the Charmix, small pins and bags that increase a fairy's power greatly. In the final episode, the Winx and Specialists defeat Darkar and save Magix once again. New to the season are pixies, very small creatures that often bond with fairies. Helia also joins the Specialists and becomes Flora's boyfriend. By the end of the season, Bloom is Sky's girlfriend, Stella is Brandon's, and Tecna is Timmy's. Musa and Riven have also gotten closer.
