//From the Corvo documents//
Earth was one of the first corvo colonies. The Corvo have several established bases, of which some are shared with the natives and used for business with human cities and towns. Corvo sell them food, crops, clothes, weapons, and many other resources needed for survival in exchange for natural resources, labour, and mercenary work. Many warlords give dozens of young men and woman to the corvo military forces in exchange for weapons to maintain their control over the local populations.
Corvo are also interested in tech-archaeology from the human period previous to the Fall. Most of the hardware is broken and the software corrupted or the language now forgotten, but the Corvo have already found several pieces of software of great value which have been implement into their own systems, after a few modifications of course.
