Snow, Shadow, and Storm

Not too long after the Trix had helped the Winx defeat Valtor for the second time, a new threat soon looms over the Magical World. The Shaman Witch-once only a shadow of Icy's past as the princess of Diamond-has returned to seek rein over Magix, and soon the entire universe. The Trix, Icy, Darcy, and Stormy seek refuge at Alfea and are helped by an unlikely ally.

Forced into the ordeal of working with one another, both groups journey into Oscurita-the Dark World-to find the ten elements that assisted in creating the Magical Universe itself in the first place within themselves along with a forgotten transformation: Inseimix. With that transformation and the bonds created the Shaman Witch may just be defeated.

Until they find out that the Shaman Witch is more powerful than anything they've ever known...
