The Winx and Roxy receive from the headmistress the seven Stones of Memory to travel back in time: only in this way, they will be able to save the Digmoles. At Alfea in the ancient past, the Winx are surprised to meet none other than a young Faragonda (a freshman student back then), who has one of the digmoles as her own fairy animal. But her roommate, Kalshara, has plans involving the ancient hall where a source of vast wild magic resides.
