For lore, see drake.

Drake mounts are epic flying mounts available by many ways. Both Alliance and Horde players can acquire these mounts.

Drops

Azure Drake and Blue Drake can be found inside Alexstrasza's Gift after defeating Malygos inside the Eye of Eternity in both 10 and 25-man versions. For a time during Wrath of the Lich King, the blue drake was a rare find in the [Cache of the Ley-Guardian] after defeating Ley-Guardian Eregos inside The Oculus when using the Dungeon Finder. This change was made in patch 3.3.2 to encourage players to complete the instance instead of abandoning it.
