Columex, originally known as Nardolin, was a planet located in relative proximity to the Vorzyd Cluster of the Outer Rim Territories, on the Perlemian Trade Route. The planet was colonized by Humans from Commenor.
When Columex joined the Commonality after the dissolution of Xim's empire, the Commonality became part of the Galactic Republic, gaining representation in the Galactic Senate. Columex was the homeworld of Senators Jheramahd and Simon Greyshade. The planet was razed by the Yuuzhan Vong during their invasion of the galaxy.
