Alignment

A characters general moral and personal attitudes are represented by its alignment, which is derived from a 2D range from good to evil, and lawful to chaotic.
Alignment is a tool for developing your character’s identity. It is not a straitjacket for restricting your character. Each alignment represents a broad range of personality types or personal philosophies, so two characters of the same alignment can still be quite different from each other, and an alignment can change as the character develops.
