The Corpus are a dominating proto-corporation of humans that maintain and operate the trade routes of the Solar Rails. They are rarely seen by others and are better known for the robot proxies that serve for them. The social structure of the Corpus is said to reflect ancient mercantile guilds from the Old Earth. Their production methods blend technology and ritual, in-part, because the ancient Orokin materials they use are inscrutable to them. They control the entire supply chain of goods that flow through the solar system.
The Corpus view Orokin artifacts as resource to be exploited for profit− at any cost.
