Denon was a planet at the intersection of the Hydian Way and the Corellian Run. It was a large center of population, commerce, and industry, second only to Coruscant. The planet's surface was almost entirely covered in ubran development, the Greenground District was the last remaining area with a small measure of exposed surface. As a result, large tracts of the surface held a potent stench related to the development and pollution. The planetary government was attempting to clean it up by the third century after Ruusan, but progress was slow. The planet was home to Czerka Arms, which had its headquarters in the Akermal District and its research and development facilities at 123 Czerka Place in the Greenground District. Governmental Investigative Network Special Agent Evening Delwynn and her team visited Denon 702 BBY to investigate a connection between Hazar Tordana, the head of Czerka, and his company to a series of mysterious deaths and conspiracy.
