The Zodiac Braves can be a reference to two different groups in Final Fantasy Tactics. It can refer to a group of 12 warriors in the Church of Glabados legend who defeat the Lucavi using 12 Holy Stones. It can also refer to the Lucavi and those they possess.
What are the Lucavi?
The Lucavi are demons in Final Fantasy Tactics working in secret under the cover of the Church of Glabados to revive their dead leader, Ultima the High Seraph. There are at least seven Lucavi, though one of them, Elidibus, is not necessarily connected to the other six.
However, 12 brave knights appeared, each of them carrying a Zodiac Stone, a magical stone with a Zodiac Sign carved onto them. With the power of the stones, the “Zodiac Braves”, as the people called them due to the Zodiac Signs they carried, fought against the demon. Valiantly, they drove the demon back to the netherworld and returned peace to the land.
But this is just the legend that Glabados incorporating for their legends.
To further strengthen Ajora’s image, the Church of Glabados incorporated Saint Ajora into the legend of the Zodiac Braves. They claimed that Saint Ajora led the twelve Zodiac Braves against a demon summoned by the King of Limberry.
But it seems that the truth might be more unsettling. Consider that Zodiac Stones in Final Fantasy Tactics turns characters into Lucavi. Wiegraf, Volmav, Elmdor all became Lucavi. Could this have the same effect on the knights calling themselves the Zodiac Brave? Seems like they’d have to match her power as well.
In this sense, Ramza is killing the Zodiac Braves and we may or may not get a prequel about this. But if we did, think about the amount of tragic depth it would involve?
