Enchanted Fey Dragon

The Enchanted Fey Dragon is an iridescent sprite entrusted with protecting the Emerald Dream, absorbing magic and exuding style. A mysterious and magical creature, it lives for excitement and has a zeal for adventure. True to its characteristic flair, the Enchanted Fey Dragon shifts its skin color on a whim, making big gatherings of these mystic beasts an awesome sight to behold. Saddle up on one of these and enjoy the instant street (and sky) cred that comes with being one of the last bastions of cool.

Unlike the mounts from the World of Warcraft Trading Card Game, this mount is directly purchasable from Blizzard. Released on November 21st, 2013, it is the sixth mount to be offered in this way.
