Plague was a typical Marauder-class corvette type of warship.
This Plague was the property of a mercenary organization whose base of operations was the one-time Azzameen family space station. It met its end when Emon Azzameen, Aeron Azzameen, together with units from the Alliance Fleet, including Ace Azzameen, launched an assault that destroyed it. The Plague, along with its contingent of starfighters, failed to hold off the attackers, and the Alliance reclaimed the station.
The 1999 video game Star Wars: X-Wing Alliance included the Plague. Furthermore, the ship got a mention in the Prima Games guide for the game, although the name of the Marauder-class corvette was incorrectly spelled Plaque.
