Set in the fantasy realm of Eorzea, players take control of a customized avatar as they explore the land and are caught up in both an invasion by the hostile Garlean Empire and the threat of the Primals, the deities of the land's Beastmen tribes. Eventually, they are embroiled in a plot by a Garlean Legatus to destroy the Primals by bringing one of the planet's moons down on Eorzea. After its alpha test and a delayed beta test, the game went live on September 30, 2010, remaining active until its servers were closed on November 11, 2012.
