Palladium was a bar in Doom City on Coruscant. In 0 ABY, it was owned by Borga the Hutt, who used part of the establishment as an audience chamber.[1]
Behind the scenes
Palladium appears in Il faut sauver Miss Pickalho, a French-language scenario for Star Wars: The Roleplaying Game which appeared in Casus Belli magazine in March 1999. As this material was not approved through the Lucas Licensing process, it is considered non-canon.
Nonetheless, the bar's owner Borga the Hutt has appeared in subsequent officially-licensed material.
