"Exogenesis Refineries"

"On the edge of known space, vast mobile refineries crawl across desolate alien terrain, harvesting and processing rare extraterrestrial minerals found nowhere else in the galaxy. Built to endure hostile worlds, these colossal machines function as both fortress and factory, shielding their crews while converting raw alien ore into priceless energy-rich alloys. Smaller armored transports support their operation, scouting extraction zones and ferrying resources back to the main refinery."
