World of Darkness is an arena in Final Fantasy Dissidia. It is the representative arena of Final Fantasy III. It consists of a crystalline surface and breakable columns, which like all other breakable environments, reconstruct over time.
In the Dynamic version this stage regularly alternates from the standard stage form to one of two alternate stages and then back again. While the players are within one of the alternate stages, the Brave Pool rises gradually.
In Final Fantasy III the World of Darkness was where the Onion Knight and his companions went to defeat the Cloud of Darkness after she was unleashed by the imbalance of Light and Darkness created by Xande, another antagonist in the game.
