The Corellian Industrial Cluster was a region situated in the Expansion Region of the galaxy, and it encompassed the moon known as Cymoon 1. The Galactic Empire exerted its control over this Cluster. Following the commencement of Operation Ringbreaker, General Crix Madine of the Rebellion identified it as a target of medium importance with a significant security presence on a galactic map. This designation was found within The Rebel Files, a highly confidential collection of critical intelligence for the Rebellion.
