The Guardians are stunned to learn that their math teacher Mrs. Rudolph is the Meridianite nanny who brought Elyon to Earth twelve years ago. She opened a portal with the Seal Of Phobos... but lost it during the escape. On the run from castle guards, Caleb and Blunk split up. Blunk hides in a sewer where he finds The Seal where it has lain undiscovered for twelve years. Not knowing what he has, Blunk begins waving the Seal around, opening portals all over Heatherfield, which the Guardians rush to close. But the girls don’t realize that every time they do, they’re cutting off an escape route Caleb needs to avoid capture. When the Seal of Phobos encounters the Heart of Candrakar the two amulets battle and the Heart ends up absorbing the talisman and all its powers. Thus empowered, the Guardians are able to help Caleb escape from the work-yard in Hoogong Gorge. Back in Heatherfield the group uses the Seal to open The Book of Secrets, revealing for the first time Phobos’s plan for draining his unsuspecting sister’s powers and turning her into a Whisperer, imprisoned within a Black Rose forever.
