No one really knows who made the Darkmoon Cards or what their true purpose is, but I can tell you that they have been found all over Azeroth, usually in the hands of a villain attempting to unlock their mysteries.$B$BThere are four types of Darkmoon Cards; Beasts, Elementals, Portals and Warlords, with eight cards, Ace to Eight in each suit. If you collect all eight of one suit then you can turn them into a deck that you can give to our Professor Thaddeus Paleo in exchange for a powerful trinket.
