5x15 - Winx Club

Tritannus plans to activate the Emperor's Throne; the Winx must restore order when Tritannus takes the seal from the Pillar of Light. The whole of Magix is plunged into darkness. Solaria is the most affected, especially King Radius who gets sick because of his connection to the sun. The Winx Club goes to the Infinite Ocean to restore the Pillar of Light. Stella succeeds in gaining her Sirenix spell, The Light of Sirenix, which sends Tritannus' mutants packing. Bloom attacks Icy, which causes Tritannus to get angry and attack Bloom and Aisha.
