Crayton from The Power of Six is Ella's Cepan. Though he was not officially made her Cepan on Lorien (she was too small to have been given one yet) he acts as the defacto Cepan for both Ella and Marina. Marina inadvertantly thinks that Crayton is a Mogadorian as she's never seen one before. Later, when he kills an actual Mog, she realizes that he's one of the good guys.
