First and foremost, Square Enix revealed a new playable race that will be introduced in the expansion. The Au Ra (pictured above) are a lean, tall race with long tails, scales and horns sprouting from their heads. In the screenshots and video footage shown so far, male and female Au Ra look very different, almost like entirely different races.
Players returning to Final Fantasy 14 to check out the new race will also be able to play with two new jobs — the damage-focused machinist, who can wield guns and craft turrets, and the healing-focused astrologian, who comes equipped with magic abilities to help buff up party members. These are in addition to the previously revealed dark knight class.
Square Enix also took time during the Fan Festival to show off Heavensward's new end-game raid, a mechanical fortress named Alexander. As with many of Final Fantasy 14's best features, that name should spark a hint of recognition and nostalgia in long-time fans of the franchise.
Square Enix revealed that fan-favorite composer Nobuo Uematsu will be returning to create the main theme for Heavensward. It also announced a Collector's Edition for the expansion pack, which will include a dragon figurine, an art book, a disc with trailers and other videos and several unique in-game items, such a griffin mount.
While we've got plenty of details to salivate over now, we've still got a while to wait for the full expansion. Square Enix plans to launch Final Fantasy 14: Heavensward in spring 2015.
