New Adasta was the capital city of the planet Ziost, the original seat of the old Sith Empire, and a major commercial, political, and population center of the reconstituted Sith. A metropolitan city, New Adasta was constructed atop a rocky crag in the tundra of Ziost, and the city's Central District was in fact located in the cave underneath that crag. The centerpiece of the city was the People's Tower, a large skyscraper similar in design to the Imperial Citadel. During the Invasion of Ziost, the former Sith Emperor Vitiate focused a significant portion of his attention and power to New Adasta as he possessed the population of the planet.
