FFXVI - Crystalline Dominion Banner

The Crystalline Dominion sits at the heart of Valisthea, built around the tallest of all the Mothercrystals, Drake's Tail. Many bloody battles were fought for control of this small plot of land due to its strategic importance, till the warring realms finally agreed to an armistice. As part of the peace treaty, the islands around Drake's Tail became an autonomous dominion led by a council of representatives from the surrounding nations—each realm enjoying equal claim to the Mothercrystal's blessing. No Dominant makes their home there.

Official description[1]

The Crystalline Dominion (クリスタル自治領, Kurisutaru Jichiryō?, lit. Dominion of Crystal) is an autonomous island dominion in the world of Final Fantasy XVI, built around the tallest Mothercrystal, Drake's Tail, in the center of the Twins, which is also depicted on its emblem along with the four Dominant-led nations' emblems.


The predecessor nation to the dominion was established in the Year of the Realm 790. In the year 820, the Iron Kingdom deployed a spy named Ishtar to the dominion's predecessor to gain power and spread the faith of Crystalline Orthodox, which worships the Mothercrystals as deities. In four years, Ishtar had gained prominence and declared the region independent and the dominion closed its borders. In 825, war over Drake's Tail broke out due to the dominion's predecessor trying to lay claim to it. The combined forces of Veldemarke (nation in Ash prior to Waloed), Sanbreque, and Dhalmekia halted the war, and governed the dominion together. In the year 833, Ishtar was discovered to be a spy from Iron Kingdom, and the Crystalline Orthodox faith was suppressed in the region and many followers were massacred in a religious cleansing, which only ended when the orthodoxy's followers committed mass suicide in Fawn Coast. The Crystalline Dominion regained independence in 845, and Rosaria, Dhalmekia, Sanbreque, and Waloed (which had rose to replace the Kingdom fo Veldemarke by this time) agreed to let the Dominion stay as an independent nation if they stay neutral.[2]

In 873, the armies of the Holy Empire of Sanbreque launched a massive attack and invaded the Dominion, moving the imperial capital from Oriflamme to Twinside.
