Elyon is Phobos's sister and the true heir to the throne of Meridian, she just does not know it yet. Vathek overhears Phobos and Lord Cedric's plans for capturing her and hurries to tell Caleb only to end up running for his life when Cedric comes to stop him. Vathek and Blunk escape to Earth with Cedric and a worm-looking monster, called a Larvek hot on their heels. Vathek relates the news to Caleb who relates the news to the Guardians and they go after Elyon to keep her safe from Cedric's clutches, however, they have to hold off the Larvek from eating Vathek and Elyon slips off in a bad mood after her new beau gives her the heave-ho. She heads back to her place of comfort: Cedric's bookshop. In the B-story, Elyon starts dating with Bryan, but, thanks to Guardians' keeping the eye on Elyon, Bryan breaks up with her.
- The rebellion and the W.I.T.C.H. girls find out that Elyon is the Light of Meridian.
- In "The Key", they are friends with Vathek, but in this episode, they don't remember his name. This is probably due to the fact that he didn't assist them in their previous adventures.
- This episode marks the only time Cornelia Hale uses "Earth Arise!" as a call-out (when she is fighting the Larvek) instead of simply "Earth!"
