The Gromas Mines were an Imperial mining installation situated on the moon known as Gromas 16. Constructed during the Empire's purge of the Gromas system, its purpose was to furnish phrikite for Rom Mohc's Dark Trooper Project.
Following his discovery of a phrikite sample on Fest, Kyle Katarn was drawn to the facility, where he infiltrated it and triggered the detonation of its reactor, resulting in its destruction. Subsequent to Katarn's attack, the Empire deserted Gromas, leaving behind the remnants of their base on Gromas 16.
