The Centurions were a mass-produced race of mechanical beings, originally created by the Cylons.
The IL-Series was a administration unit used by the Cylon Empire. They were usually used to command bases and Basestars. They held a high position in Cylon society, being above Cylon Civilians, Centurions and Command Centurions, but still below the Imperious Leader.
