CMC-3 was formerly a mining installation situated within the Cularin asteroid belt, previously operated by the Czerka Mining Corporation. It had been deserted for an extended period when, during the era of the Clone Wars, the Liana Liberators journeyed to this location aboard the space yacht named Perihelion. Their purpose was to find refuge while formulating a strategy to slice into key computer networks within the Cularin system. During their stay, they brought back online certain operational aspects of the outpost, notably the tractor beam and a substantial cutting beam. These were employed in an assault against the Starchaser IV and Shiana Trist's Z-95 Headhunter when they made their arrival at the facility, seeking to apprehend the Liberators.
