A door to the past has been opened.
Cavernous Maws have appeared throughout Vana'diel, connecting to a time 20-years ago when the world was engulfed in the Crystal War. The nations of Windurst, Bastok and San d'Oria have suffered heavy losses, and the Shadow Lord's armies are marching strong.
Why has this door been opened? Which stories of the past can be rewritten? Is an unknown villain in the past trying to bring the doom of the future?
