The region was an experiment in corporate-controlled worlds settled during the Galactic Republic's Great Manifest Period beginning in 20,000 BBY. Unrelenting exploitation by Corellian and Duros/Neimoidian corporate interests of the worlds of the Corellian Run had impoverished countless native species and contributed to environmental despoliation. Galactic colonization was forced to shift farther eastward towards the Perlemian Trade Route.
