character diamond

character diamond
 n.— «Freeman teaches characters as a series of layers. One layer is the character diamond. Each corner of the diamond represents a major trait in the character’s personality. A trait helps shape how the character sees the world, speaks, thinks, and acts. “Character diamond” loosely means the combination of three, four, or five traits that govern a character’s personality.» —“Making Personas Sparkle Like Diamonds” by Bryan Eisenberg ClickZ Jan. 21, 2005.
