Cartann City served as the capital city for Cartann, which held the position of the most influential nation state located on the planet of Adumar. Furthermore, it was the planet's largest urban center.
The structure of Cartann City was hierarchical, with the less affluent workforce residing in subterranean areas. Its aerial corridors were dense with comm cables, arranged at different heights with considerable spacing to facilitate the passage of starfighters without difficulty. Following the Red Flight's mission for diplomacy and the following civil war, the city underwent reconstruction, and numerous underground residents were presented with the option of residing above ground. By the year 40 ABY, it functioned as the governmental capital for the entire planet.
