Qiae

The Qiae are a species of sentient crystals native to Pulse.

Description
The Qiae are giant, sentient, near-omniscient crystals that aim to bring about great change on Pulse, but it is unknown whether this change is for good or for evil. Qiae will occasionally choose someone to carry out their plans of change, who then becomes known as an l'Qiae. The most recent known l'Qiae was a woman named Lightning who fought with a resistance movement against martial law on Cocoon that was caused by fear of the Qiae.

The residents of Pulse's floating cities have an irrational fear of the Qiae to the extent that anything from the surface world is feared to be influenced or contaminated and is locked away from the public eye.

Trivia

 * The Qiae appear to be based on the fal'Cie from Final Fantasy XIII.
