The ability to focus one’s mind is vital to a Force user. Though one must be sensitive to the Force in order to use it, if a character has no Discipline, he can never hope to master his abilities. In addition, characters may confront countless horrors as they explore the galaxy. Some of these are natural, if terrifying: the rancor, the krayt dragon, and the wampa, to name a few. Others, such as the Death Star, may be constructions or artifacts, and still others—such as a vergence of the dark side of the Force—may be supernatural. The ability to maintain composure and react in an effective manner is also governed by Discipline. This skill represents a character’s ability to control his biological instincts so that he can overcome things that might induce abject panic in a person of lesser resolve.
