The King of Swords represents the professional aspects of authority. Often associated with those in legal or business careers, he most likely represents someone who will aid you in one of these fields. This person may be assertive, or even seek to dominate you in their confidence that they know how best to aid you. While they may be friendly, their primary motivation is unlikely to be emotional.
