Sel Zonn Station is one of over a dozen XQ2 Space Platforms in orbit around Brentaal. Manufactured by Bengel Shipbuilders some years before the end of the Republic, Sel Zonn Station has not flourished since the rise of the Empire. Though it still sees a great deal of traffic from Brentaal and from travelers, the Empire has allowed large sections of the station to languish and fall apart. Thanks to the rise of anti-alien sentiment, especially on the Core Worlds, the more run-down sections of Sel Zonn Station are now inhabited by aliens. As such, a rift divides the station—wealthy, privileged Human Imperial loyalists occupy the nicer sections of the station, while all others are relegated to worn and sometimes dangerous secondary sections.
