The platform was built by the Terran Confederacy to house the few maintenance teams for automated mining sites on Char after the Guild Wars. During the Great War, it was infested by the zerg and used as an orbital nesting site and hatchery.
During the Brood War, Sarah Kerrigan made the platform her base of operations, bringing Matriarch Raszagal there to use as leverage to get Dark Prelate Zeratul to kill the Overmind for her. However, Zeratul circumvented Kerrigan's defenses and rescued Raszagal just as Samir Duran finished relocating Kerrigan's primary hive clusters to the platform.
