Empress Teta, formerly known as Koros Major, Koros, and also known as Cinnagar, was an ecumenopolis world in the Deep Core. It was named after the Koros system's ruler Empress Teta, who unified the system following the Unification Wars in 5,000 BBY. It was the capital of Teta Sector and was located on both the Koros Trunk Line and the Carbonite Run, and for a short time on the Daragon Trail. Empress Teta was the main hub of galactic civilization in the Deep Core and was also one of the few highly urbanized planets in the region to rival Coruscant itself in fashion and amenities.
