Personality, like alignment, is a tool for developing your character’s identity. It is not a straitjacket for restricting your character. Consider them a shorthand notation for these fundamental facets of the character you are role-playing. Aptitude, Persona, and Ego generally correspond to a character’s mental abilities, but this does not need to be the case. Some traditional belief systems hold that the Elements themselves are responsible for aspects of individual personality.

Aptitude

One’s capacity for novelty; from open and curious to closed and cautious. Generally corresponds to Intelligence.

Persona

One’s social demeanour; from outward and extroverted to inward and introverted. Generally corresponds to Charisma.

Ego

One’s self image; from anxious and neurotic to stable and confident. Generally corresponds to Wisdom.
