Psyche

Psyche is a term for the mental and spiritual well being of a character.

A character with no psyche has gone (or maybe always has been) completely raving mad. Whenever a character experiences something horrific or traumatic, a Psyche test should be called for. If failed, sometimes a character is given some sort of mental illness or penalty.

Poor psyches include Bram Stoker's Renfeld, Macbeth, or overworked postal employees, while examples of good psyches include Lewis Carrol's Alice, Tony Robbins, and counselors.
