Auroria is the capital and largest city of Selucia. Auroria dominates the Corgana region and is one of the world's oldest cities, having been founded, according to legend, in the 8th century BCE. During Classical Antiquity Auroria was a powerful city-state and centre for the arts, learning and philosophy, as well as the unofficial capital of the entire Selucian archipelago. During the Middle Ages Auroria slowly fell under the political control of the Arch-Patriarchy, which had been established in the city since the 1st century CE, and is thus one of the major centres of Hosianism. In modern times, Auroria is a large cosmopolitan metropolis and central to economic, financial, industrial, maritime, political and cultural life in Selucia.
