The Cryst-Fairies are humanoid, fairy-like creatures that appeared in Bravely Default and Bravely Default: Praying Brage. In the Crystal Orthodoxy, the Cryst-Fairies are supposed to be the tenders of the Crystals. The only notable Cryst-Fairy is Airy.

Profile
According to the Orthodoxy's teachings, the Cryst-Fairies are helpers of vestals in their responsibility to tend to the crystals. The Cryst-Fairies always ensure that the vestals and even other Crystalists pray to the Crystals and uphold the faith.

Not much is known about the Cryst-Fairies, other than their responsibility to the Crystals being top priority.

Airy, a Cryst-Fairy (by proclamation) used her title to deceive Agnès and possibly other vestals in the past to make them drive the Crystals out of control. Such an event will produce the emergence of the Holy Pillar, which Airy exploits to weave together Luxendarc and its parallel counterparts. Airy actually serves Ouroboros, the Bringer of Ruin and Devourer of Worlds.

Since before the time of the 'Angel' that appeared before Sage Yulyana and Lord DeRosso, Airy has been deceiving the vestal and exploiting the Holy Pillar to weave the worlds together for Ouroboros. But, her plan was foiled by the Angel (which later revealed to be one of the Warriors of Light) with her over-awakening a Crystal, causing it to shatter. Airy killed the 'Angel' and her companions, but the Angel managed to foretell the omens and the horrible future of Luxendarc, which Sage and Lord DeRosso desperately tried to prevent from happening.

So far, the only notable Cryst-Fairy is Airy. If the original teachings about the Cryst-Fairies were true, it is possible that the other Cryst-Fairies were killed by Airy herself so that she would be the only Cryst-Fairy to be trusted by the vestals.

However at the end of the game, a Cryst-Fairy appears and thanks the player for dealing with her "sister". Suggesting that Airy may have been corrupted by Ouroboros.
