Expansion of the Knight in a Deck of Cards

Finally the Knight of Spades has come to light.  The expansion of the Knight into a deck of cards is important since they already exist in a Tarot deck.  The Knight ranks above the Jack and below the Queen in a normal deck.  Yet ranks below a Baron and Baroness in an expanded royal deck.   Thus there is also the Knight of Hearts, Knight of Diamonds, and Knight of Clubs.

Knights are represented by the letter G.  K is already taken by the King. G can also mean Gallantry as in a Gallant Knight saved the day.
