that Elyon is Prince Phobos's younger sister who had disappeared from Meridian more than a decade ago. After Prince Phobos's right-hand man, Lord Cedric, revealed Elyon of her true alien heritage, he manipulated her into thinking that the Guardians were her enemies. The Guardians had to find a way to defeat Prince Phobos and bring Elyon back home. In Meridian, however, there is a rebellion taking place led by Caleb, whom Cornelia had seen in her dreams for years.
