Lumoria

Lumoria is an undersea region in Final Fantasy XI. It contains the ruins of the Celestial Capital Al'Taieu, a legendary Zilart city lost over ten thousand years before the beginning of the game's story. It is the ultimate destination of the Chains of Promathia expansion.

Al'Taieu
The twisted landscape of Al'Taieu was once the outskirts of the Celestial Capital. The surviving structures of the Zilartian city loom at its center. It remains the residence of many strange and dangerous creatures including the infamous Absolute Virtue. A phenomenon called an Auroral Updraft connects this place to the Sealion's Den.

Grand Palace of Hu'Xzoi
The Grand Palace is the greatest edifice of the ancient Zilart and the former home of their royal family. It consists of five towers surrounding a wider central structure.

The Garden of Ru'Hmet
The garden contains the upper levels of the Grand Palace. The Zilart King was once seated atop its halls. The central elevator here descends to the Empyreal Paradox.

Empyreal Paradox
The Empyreal Paradox is inexplicable area, both beneath the Garden of Ru'Hmet and outside Vana'diel entirely. What occurs here can only be said to determine the fate of the world itself.
