Doom of the Lighthouse Star

Sinossi

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.
