A Dirt Digger is basically a slave. They wear a latex based suit that makes them unable to speak, eat, or drink, and the suit cannot be removed easily. To eat, they're given saline/nutrient injections. To speak, they talk through a wireless network that changes thoughts to words. On their chest is a set of triangles, 1 to 5, which is a ranking system. On the left pectoral is a bar code that can change to the slave's name or serial number.
