Krystal strives to mend Sky's fractured memory, yet the recollection of losing the pendant of Eraklyon remains the source of the obstruction. Only Sky knows its whereabouts.

In their quest for the tome, the Winx discover a counterfeit; it transforms Tecna into a terrifying automaton, programmed with a singular mission: to locate the Sirenix Book.
