Blessed with eternal youth by a crystal, Queen Isolde slips into Julian’s engagement in secret—only to be wrongly accused by Mabel as his mistress and targeted for death. When the lie falls apart, Mabel invents a pregnancy, but something far darker is growing inside her. To stop it, Isolde, Julian, and King Gareth stand together and defeat the demon. With peace restored, Julian takes the crown, while Isolde and Gareth retire side by side.
