Slit Throat

You bear an ugly scar across the throat from where it was cut. You are mute as some part of your ability to vocalize, either the vocal cords or the nerves in the area, were damaged when your throat was slit. As such, you communicate predominantly through common sign language.

You have disadvantage on persuasion checks as they generally involve speaking. You gain advantage on insight checks due to having become more aware of nonverbal cues like body language, facial expressions, and other "tells" like verbal intonation.
