Submissive Brilliance was the monitor of Installation 02, and one of the smartest Forerunner AIs. However, he eventually became rampant, and started to plan to conquer the galaxy by destroying the Reclaimers and claim what remained of the Forerunners' Empire for himself. For this, he constructed more and more Sentinel construction facilities, creating more powerful versions and increasing his number of loyal robotic servants. He even went as far as to experiment with the Flood specimen on his installation, attempting to genetically create new versions of the already deadly creatures. He even attempted to activate his installation again, but without a Reclaimer or Forerunner, he have failed.
