Cartann City was the capital city of Cartann, the most powerful of the planet Adumar's nation states. It was also the largest city on the planet. Cartann City had a stratified structure, with the poor workers living below ground. Its skylanes were filled with comm cables, clustered at various altitudes with wide gaps between them so that starfighters may pass through easily. After the Red Flight's diplomatic visit and the subsequent civil war, the city was rebuilt and many of the workers living underground were given the opportunity to live above. By 40 ABY, it was the government capital of the planet.
