This is a brief, public description of the personality of your character. Just a few sentences to describe the character's outward disposition, their underlying motivations that shape their demeanor, and easily recognizable personality traits. Some characters will have deeply hidden aspects of their personality, and any secret traits should be kept to the 'secrets' section of a sheet and off of the publicly accessible parts of their sheet. 'Personality' on a sheet is the outward gauge of a temperament and it can be deliberately misleading, if there is a very solid reason.
