The Winx Club go to find the missing Cloud Tower crypts to contact the three Ancestral Witches who destroyed Domino. While there, Bloom learns from the Ancestral Witches that Valtor lied and her birth parents are alive, exiled somewhere in an unknown dimension even they don't know about. Meanwhile, Valtor endows the Trix with Disenchantix abilities, which the Winx destroy with combined Fairy Dust.
