The Kingdom of Concordia (コンコルディア王国, Konkorudia Ōkoku?) is a nation that holds the Sōryū Crystal in Final Fantasy Type-0, with its capital being Mahamayuri. The Concordian people use the crystal to communicate with dragons and monsters, and use them for daily life and to strengthen their military.
Top posts in the Concordia government, save for the Concordian King, are held by women; Andoria serves as the queen and is the only one who can communicate with the Queen Dragon, the physical representation of the crystal. There are five Orders of elite knights who protect Sōryū Peristylium. One of them is known as the Akatoki, under Celestia, with Yuzuki among its members.
The territory of Sōryū (蒼竜) was originally known as Seiryū (青龍). According to legend, the male progenitors of the Seiryū people had consumed the flesh of dragons which resulted with their male descendants cursed by eventually becoming monsters known as "Seiryūjin". The female descendants, who were unaffected by the curse, took over the country in the year 252 under the name Sōryū and made Concordia into a matriarchy.
During the events of Type-0, the Concordian King, whose title is more of a figurehead, schemed to overthrow the land's actual ruler Queen Andoria and restore the Seiryū to power. When Andoria is assassinated, the Concordian King assumes control of the nation and forms an alliance with the Milites Empire to retaliate against the Dominion of Rubrum for their supposed role in Andoria's death. However, the Concordian King is frustrated to learn that the Queen Dragon, being a l'Cie, obeyed only Andoria and will listen to no one now that she is dead. Furthermore, the Concordian King rashly orders the unsealing of the Naraku cave to destroy the Suzaku troops, despite how the monsters released may endanger his own forces as well.
When Suzaku manages to defeat the combined Byakko and Sōryū forces, the Concordian King goes into hiding and is caught by Class Zero. The elite knight Yuzuki, who had accompanied the king, reveals the extent of the Concordian King's plans and the origins of the Seiryūjin before summoning one to eliminate the king once and for all. She presumably meets her demise afterward when she seals Naraku to contain the Seiryūjin within.
- The country's attributes and qualities, as well as symbolism to one of the animals of the Four Symbols is evident in its themes.
- Representing the east, Concordia is located far off on a secluded peninsula eastward from Orience's greater lands. Symbolically, the dragon has connotations with representing the eastern world, with the tiger representing the western world in Asian cultures.
- Representing the season of Spring, the nation is consistently vibrant and lush, with a gentle oceanic climate.
- Representing the Wu Xing element of Wood, the Sōryū Crystal bestows upon its users the Power of the Dragon, allowing them to communicate with beasts, and by extension, nature itself.
- Its animal the dragon, Concordia reveres them highly, with the Queen Dragon being the physical manifestation of the Sōryū Crystal itself, and the beast finds itself in the highest ranks of the military in the nation. In some mythologies, dragons have shown to have the ability to communicate with sentience and language, and even interact directly into the affairs of mankind. In real life, Asian nations also bear the dragon in their heralds and arms, being representative of auspicious and great qualities, and heavenly providence.
- Its crystal is close in shape to that of an orb. Crystal balls were often the choice cut shape for precious jewels and stones in Asian nations, as dragons in Asian mythology bared them in their claws and are representative of their closeness to creative powers and universal perfection.
- The creation of Concordia's majestic palace was actually the Focus of Shirotae, a Sōryū l'Cie.
