The Zann Consortium, a criminal organization, operated during the era of the Galactic Civil War. This syndicate often clashed with the Black Sun crime group. Among their equipment, the consortium employed StarViper-class attack platforms, even dispatching a group of them to attack a privately owned space station due to the owners' significant debts to the Zann group.
The Iron Blockade isolated some Zann operatives within the Anoat sector, severing their communication lines with their superiors. Despite this isolation, these operatives persisted in their illegal activities, particularly targeting those who had previously conducted business with Black Sun.
The Zann Consortium's initial appearance was in the Legends timeline, specifically in the Forces of Corruption expansion pack for the Star Wars: Empire at War game, developed by Petroglyph. Its initial reference in canon occurred in Star Wars: Uprising.
