Here is a helpful Darkmoon faire guide, should you need it.
The Dark Moon Faire appears monthly, early each real time month. It alternates between Elwynn Forest and Mulgore. When it is set up, a barker will appear in each major city to let you know it is active.

General Quests

# Sayge will read your fortune. You answer a series of questions and then receive a random stat buff. Afterwards, you can request a written fortune. Most of these are just funny sayings, but fortunes 23, 24, 25 and 27 all start up new quests.
Card Deck Quests
Cards drop in various high end dungeons. They are tradeable, so they can also be purchased through the AH. A set consists of the standard playing cards Ace through Eight. To get your reward, you must collect all 9 cards and combine them into a single deck to turn in to Professor Thaddeus Paleo.
