Cinder flexed her tongue, testing it, and raised her voice.I am princess Selene.Levana leaned forward. Your are an impostor!And I am ready to claim what's mine. People of Artemisia, this is your chance. Renounce Levana as your queen and swear fealty to me, or I swear that when I wear that crown, very person in this room will be punished for their betrayal.
