Aargau
a planet of some importance to the Empire, Aargau was known throughout the galaxy for its banks. It was known to many beings as the Jewel of the Zug System. By the time of the Clone Wars, Aargau was under the control of the InterGalactic Banking Clan. Much of the planet's surface was dominated by a huge pyramid, which was divided into seven distinct and vast levels that had been built one atop the other for thousands of years. All visitors reported to the uppermost level, which was the smallest and easiest to secure. Access to the lower levels was granted on an as-needed basis to those citizens and visitors with the correct credentials. The seventh level, known as the Undercity, was a lawless area where any number of illegal and criminal activites could be found. In order to ensure that individuals remained on the correct levels, specialized lasers tinted the lighting of each level to a unique color. Sometime before the Battle of Yavin, Aargau was the site of a week-long conference between Baron Tagge and the Corporate Sector companies. The result of the meeting was the formation of the Corporate Sector Authority. Aargau remained neutral during the Galactic Civil War, although Princess Leia Organa and Darth Vader played an intricate game of politics there. After the Battle of Endor, Aargau fortified itself behind planetary shields and perimeter warships. Aargau was the third planet of the Zug System, and was orbited by a single moon. The average day on the planet lasted 24 standard hours, and its year encompassed 364 local days, giving Aargau a similar calendar to that of Coruscant.
