Final Fantasy XI Online: Vana'diel Collection 2008

The world of Vana'diel is a crossroads of magic, swords, and technology. It is also a battlefield where those who believe
in light face monsters that thrive in darkness.
The struggle centers on the control of crystals:
sacred stones that are the fundamental source of all creation.

The monsters showed no mercy as they laid waste to
beautiful towns, ravaged the land, and polluted the streams and rivers of Vana'diel.
But the people united to seize victory from the jaws of the beastmen, earning themselves temporary respite from a life-and-death struggle.

Twenty years have passed since the people's great victory. But now, even as the memories of battle have begun to fade, a new evil grows inside Vana'diel…

And it hungers for the power of the crystals.
