The Judges are a recurring element in the Final Fantasy titles that exist in the Ivalice universe. Generally, Judges are the keepers of law and have held this position since their initial appearance in Final Fantasy Tactics Advance.
The in-game moderators, Game Masters (or GM's), appeared in the form of Judges, and were capable of using exclusive magic and abilities.
Judges serve under the Ministry of Law in the Archadian Empire. The highest in rank is the Judge Magisters, who are often accompanied by subordinate Judges. The Judge Magisters are effectively the Empire's Supreme Court.
The Judge of Wings is aptly referred to as a Judge by the sky pirates due to her armor's resemblance to that of Archadian Judges. However, she is not affiliated with Archadia.
The Judges are given a different persona as well as a different role. They serve Adjudged Clans where they protect them from death as long as they uphold the laws set during engagements.
Three Gartian Empire NPCs, Biggs, Wedge and Colonel Grauser, wear armor identical to the Judges of Ivalice.
