To activate the Emperor's Throne, Tritannus must obtain the seals of the throne's missing pillars. When he takes the seal from the Pillar of Light, the planets are shaken, and it is up to the Winx to restore order.
Tritannus is angry because the Emperor's Throne is not providing him the power he wants and soon discovers the legs of the throne were broken. He then gets an idea of how to activate the throne. Tritannus takes the seal from the mystical Pillar of Light. The whole of Magix is plunged into darkness. Solaria is the most affected, especially by King Radius who gets sick because of his connection to the sun.
At Alfea, The Winx minus Aisha were in the virtual chamber, swimming through an ocean setting trying to locate the circle reef. They come across it, but were confronted by some water dragons that began to darken the area. Bloom tells Stella to disperse the darkness with her light powers, but she just froze on the spot. The virtual environment dissipated and the girls were called to the control room by Faragonda. Obviously, the exercise was a failure.
Faragonda asked Stella what happened, and she could not give an answer. Faragonda fears for the Winx as the simulation was just a pale imitation of what they will face, and if they could not handle this, they will not survive long. She dismisses them for the moment. Stella was filled with self-loathing for screwing up, but Bloom tells her not to worry about it. Musa then wonders how Aisha is doing.
On Andros, Aisha reunites with her parents and tells them of what Tritannus has done to their underwater family. King Teredor then presents Aisha with her uncle King Neptune's sword, which would give Aisha an edge in battle.
Storing it in subspace, as princess of Andros Aisha vows to stop Tritannus and save her family.
In the Infinite Ocean, Tritannus, the Trix, and the mutants find the Pillar of Light, one of the Pillars of the Infinite Ocean that stabilizes the whole of Magix. Tritannus plots to steal the seals to restore the throne and become the emperor of the Magix Dimension, with Icy as his empress. Darcy again shows her displeasure about the whole thing as she and Stormy are practically tossed aside. Before they could take its seal, they were confronted by some guardian Selkies. Unfortunately, the guardians were no match for Tritannus and the Trix.
At Alfea, the girls try to find a way to restore Aisha's family back to normal. Stella calls upon her Sirenix Guardian to ask how. She responds that once Stella opens her heart to her powers, her light will shine. When the Guardian leaves, the room suddenly became dark. It was not just the room as they found out that it was getting dark all over Alfea. The sun was getting eclipsed.
Even then, it was not limited to Alfea. On Domino, Oritel and Marion look at the eclipse in horror. On Eraklyon, Erendor looked at the eclipse in worry. On Andros, Aisha became horrified as the eclipse was causing the oceans to go wild, tossing some unfortunate mermaids about. King Teredor deduced that one of the pillars of the Infinite Oceans were being tampered with.
At Alfea, Faragonda informed the Winx that the sun is getting eclipsed by a dark power, which is beginning to affect the whole of Magix. Stella became horrified as it will no doubt affect Solaria as well. Without the sun, her father, King Radius, will die. They immediately head for Solaria.
On Solaria, Stella's estranged mother, Queen Luna, looked up in horror at the solar eclipse and immediately ran to Radius' chamber, worried for his condition. He coldly tells her that it is nothing as Solaria has two suns, so there is nothing to worry about. Unfortunately, he began to spasm and collapsed, much to Luna's horror.
Soon, the Winx arrive on Solaria. Stella was surprised to find her mother there and asked about Radius' condition. Luna gives her the bad news that he is sick in bed and there is no telling how long he can last without the sun, causing Stella to break down in tears. Aisha then calls, informing them that Tritannus has struck in the Infinite Ocean. They all transform to their Sirenix modes and rendezvous with Aisha in the Infinite Ocean. They are met by the Selkies who lead them to the Pillar of Light where a fight ensues.
Flora, Musa, and Tecna immediately take down Darcy and Stormy. Bloom fights against Icy. Aisha faces Tritannus, who then noticed the seal in his hand. Seeing that he was no match for Aisha's tenacity, he once again used his mutant slaves as shields, knowing Aisha would not fight back against them, Stella then comes in to fight them. Recalling what her Sirenix Guardian said, she used her powers to repel the mutants without killing them, making Tritannus scream in disbelief. While he was distracted, Bloom fires a spell at him to take him down. To her and everyone else' surprise, Icy jumps in and takes the blow, getting critically injured in the process. Tritannus gets angry and promises painful retribution for what happened...
