The Guardsmen are the protectors of the universe. Each Guardsman was selected from among the various space-faring races of the universe by the Shepherds.
The universe is divided into sectors, each one assigned a Guardsman. Each Guardsman is granted a suit of armor as well as cybernetic enhancements that augment their natural abilities. Also, each Guardsman is assigned a semi-sentient ship to ferry them around on their patrols, as well as serve as a mobile home.
