S8·E3 Attack on the Core

The staryummies, led by Obscurum, absorb all the energy of Lumenia's core, causing the star to sink into darkness. The Winx use their new Cosmix powers to battle the staryummies, and eventually manage to make them escape. Though it seems the Lumenia's core is lost for good, Bloom comes up with the idea of using a convergence spell on the core itself, in order to try to restore it. Thanks to their new Cosmix powers, they manage to restore the core successfully. The Winx then throw a party in honor of the Lumens. Meanwhile, however, Valtor is preparing to attack Peripla, a star-ship that fly across the space.
