In this blog I'd like to add all officially confirmed Outlander Nightclub Patrons or characters that are seen in the neighbourhood of the Outlander. I've used sources as the SW Insider Magazine, official UK Fact Files, online dvd commentaries and Inside the Worlds of 'AotC'.

'Inside the Worlds' and other sources indicate that the Outlander is owned by the dangerous Baath Brothers, 'Coruscant and the Core Worlds' says it's under management of Volven Roxe, a Shistavanen.
