For some time, I thought of including a character who is mute in my second fantasy book. They would only be able to speak in wheezing, incoherent whispers and only their family and bodyguards would be able to understand what they are saying. I got the idea of an old movie I saw years back in which an old mobster could barely speak and could only be understood by his enforcers. Like that mobster, this character will be a high-ranking individual in society. Also, this character will be wickedly frightening with a sword.
