Final Fantasy Type-0 takes place in Orience, which is divided into four nations known as the Dominion of Rubrum, the Milites Empire, the Lorican Alliance, and the Kingdom of Concordia. Each of the nations is blessed with acrystal that grants them unique powers: Rubrum controls the Suzaku Crystalcontaining the power of Magic, Milites controls the Byakko Crystal containing the power of Weapons, Lorica controls the Genbu Crystal containing the power of the Shield, and Concordia controls the Sōryū Crystal containing the power of the Dragon.
The four nations coexisted peacefully under the Pax Codex until Cid Aulstyne, High Commander of the Milites Empire, broke the peace treaty and staged an invasion using advanced military technology developed with the power of the Byakko Crystal. With his armada of airships and magitek armor, Cid conquered Lorica and Concordia, then moved on to Rubrum where he faced a strong resistance due the nation's magical defenses.
Hoping to force the nation's leaders to surrender, Cid staged an attack on Rubrum's Magic Academy, Peristylium Suzaku. A small group of skilled students belonging to the Peristylium's Class Zero have retained the powers from their pact with the Suzaku Crystal. While Cid attempts to negotiate with Rubrum's president, the students of Class Zero are busy organizing Operation Apostle, a covert mission to recapture the crystal and defeat the Milites forces.
