Square Enix released the opening movie for Final Fantasy XIV: A Realm Reborn along side the announcement for beta sign-ups. You can view the beautiful opening video below. The first half of it contains the "End of an Era" trailer that was shown off a couple of months ago.
For those interested in applying to be a beta tester Square Enix has launched a website just for that purpose. Please refer to the handy source link below that will redirect you to our sister site Final Fantasy Union for more details.
