Whimsy Cards are a narrative accessory that allow players to add to the story of any tabletop roleplaying game. Distribute one card to each player at the start of play. Players may use them at any time by revealing a card and describing how the current scene or situation changes as a result. The Gamemaster is allowed to suggest modifications and even veto the use of the card, but he or she is encouraged to allow as much of the player's input as possible. The GM may then give the player another card now, or at the end of the current scene.
