The trading hub known as Mercantile Plaza was built by the Selkath on the planet Manaan. Its construction occurred years following the reconstituted Sith Empire's assault on the world. Following the attack, the Plaza represented the initial above-ground structure erected by the Selkath, and it materialized from years of discussions between the Selkath and Mahreen, a diplomat from the Republic. The Plaza was composed of two distinct areas: the Imperial Concourse and the Republic Concourse.
