The King of Pentacles embodies the mature and dependable aspects of maturity. Anyone represented by this card is tied to success and status. While it may refer to your own characteristics, the Kings most often stand in for other people in your life who can aid you. You can expect this person to value prudence of intelligence, and, if it represents an event, it may be a financial windfall or promotion.
