Therum is a distant but rich industrial world claimed by the human Systems Alliance. Its plentiful heavy metals have fueled the recent manufacturing boom on Earth. Core samples rich with the fossils of simple silicon-based organisms indicate that Therum was more habitable in the past than it is at present. Perhaps this explains the many Prothean ruins dotting the surface, most of which have been looted by mining corporations.
