Winx Club Season 8 Episode 6 - Doom Of The Lighthouse Star Episode Title:Doom Of The Lighthouse Star.Episode Description:The Winx and Twinkly follow Orion to Iridia, the star that lights Prometia. There, they try to restore the core of the star, unsuccessfully. They discover that the planet's core has been completely destroyed, that even with their Cosmix powers they cannot repair it. Twinkly finds her friend Lumilla and the two have a little tea party. Orion, disappointed by the failure of the Winx to fix the core of Iridia, is contacted by Valtor, who offers him a deal: if he helps him to take out the Winx, he will save Prometia, Orion's home planet, by restoring the core of Iridia. Orion agrees to the deal, and sets up a trap on Prometia for the Winx. He then sends the Winx to Prometia on a false pretence to use a radar he made to fill Prometia with artificial light. The Winx goes to Prometia, but when they arrive at the right spot to place the radar, the trap Orion has set for them is activated, and the Winx falls into it.
