W.I.T.C.H.

The Guardians must save Meridian from the evil sorcerer Phobos and Cedric, who are pursuing Phobos’ sister—the long‑lost princess of Meridian and the true heir to the throne. They locate her, and the Guardians then set out to rescue her from Phobos. When Meridian is freed and the rightful heir ascends the throne, a new enigmatic sorceress named Nerissa frees Phobos’ top henchmen and reforms them as the Knights of Vengeance. Once the Guardians learn more about Nerissa and her plan to reunite former Guardians, they are able to defeat the Knights, only to face even more powerful Knights, in addition to the former Guardians attacking them.
