Witness the end of an era as the Eorzean Alliance clashes with the Garlean Empire in a bid to deliver the realm from certain destruction.
The saga will continue in FINAL FANTASY XIV: A Realm Reborn.

The events in the video will end the current era and 2.0 will take place 5 years after
The events are explained here
The Seventh Umbral Era is a cataclysmic event prophesied to happen in the near future on Final Fantasy XIV. The entire Seventh Umbral Era subplot is being used by the development team to explain in-lore several updates - such as enlarging monsters and other events, all of which will culminate in the release of Final Fantasy XIV: A Realm Reborn, as the cataclysm will reshape Eorzea itself, justifying the new version's updated maps. The last umbral era happened 1,500 years ago.
This part of the game's history, along with the servers, has come to a climactic end as of midnight (PST) of November 11th, 2012, but soon the servers will be restored until Final Fantasy XIV: A Realm Reborn. The climax, a Youtube video called End of an Era, was launched just after the severs went down.

it's pretty awesome to have an apocalyptic event as an ending towards a game's rehaul
Anyways, Square Enix, as always, makes really great animated movies
