Duscur boasts no noteworthy features, but is rumored to be rich in valuable minerals. Its people practice polytheism and worship a pantheon of different gods, viewing the gods of other countries as equally valid and incorporating them into their own pantheon as they did with Sothis. Revealed in the support conversation between Mercedes and Dedue, Dedue claims that the “oversimplified” version of the creation of Duscur involved the sky god becoming angry with the earth god and, in retaliation, created Duscur.
According to Dedue, Duscur had many scattered towns, with each one specializing in one trade. Duscur was also home to several unique flowers native to the region.
Duscur is a formerly independent country. In Imperial Year 1176, a number of members of the royalty and nobility of the Holy Kingdom of Faerghus were assassinated. Among those lost were King Lambert and Glenn, the elder son of Rodrigue. Crown Prince Dimitri was the only survivor of the attack. In what became known as the Tragedy of Duscur, the Kingdom blamed the people of Duscur for the attack and nearly exterminated them in retaliation.
House Kleiman, which originally held only a lordship over a single castle in the Kingdom's west, was awarded the noble title of viscount and granted the entire Duscur region as its feudal estate in recognition of its successes in the subjugation of Duscur. As of 1180, Duscur and its few remaining people remain under House Kleiman's dominion.
Several paired endings on the Azure Moon route such as Dedue and Dimitri will see the country restored as a nation, returning its autonomy and the land back to the people of Duscur.
