The Mercantile Plaza was a trading platform constructed on the planet Manaan by the Selkath, years after the reconstituted Sith Empire's attack on the world. The Plaza was the first surface structure constructed by the Selkath after the attack, and was the result of years of negotiations between the Selkath and the Republic diplomat Mahreen. The Plaza consisted of two platforms—the Imperial Concourse and the Republic Concourse.
