Meridian is a human Outer Colony and the seventh natural satellite of the gas giant Hestia V in the Hestia system. Despite being located on the edges of human space, Meridian was a vibrant and thriving colony with a robust economy and an impressive population; mining and military production for the UNSC were known industries on the colony. Once a green world, the moon held a temperate climate and fertile land. The Covenant eventually attacked the world in 2548 and, after a long battle that lasted for three years, Meridian was ultimately glassed by the Covenant in 2551. Following the Human-Covenant War, Meridian was resettled by the Liang-Dortmund Corporation. Despite being a colony of the UEG, Meridian became an independent world following the Covenant War.
