First, there's the character of Agnes. In Bravely Default, Agnes bore the title of Vestal as she traveled to awaken the four crystals. In Bravely Second, it seems Agnes has received something of a promotion, as she's now being referred to as pope of the Crystal Orthodoxy. We imagine being pope has its advantages - like being freaking pope - but on the downside, it also makes you prime kidnapping material, which is exactly what happens to dear Agnes.
The Crystal Orthodoxy headquarters are located in Guatelatio, a city that will be introduced in Bravely Second. According to Gematsu, Guatelatio guards the highway that leads to the Temple of Earth and the Holy Land. Within its walls, Guatelatio also holds the Gate of Faith, a military institution that trains Orthodox Knights.
So we've got the savior of the world, a military organization, and a lot of religious undertones. What could go wrong? Guess we'll find out when - and if - Bravely Second is released outside of Japan. But then, even Japan isn't sure when they'll get their hands on the game, as Bravely Second has yet to be given an official release date.
