2604 Shaded Rage was a monitor created by the Forerunners and given an installation to watch over. It was made as a Shield World of some sorts, as well as having a function of serving as a home for creatures that can survive in the type of atmosphere for the Installation. His eye constantly changes colors between green and dark blue, and he appears to believe he was the only monitor that was not insane. Shaded Rage was equipped with the same technology that every other monitor had. The Constructors on the Shield World were quick learners, and thus Shaded Rage was able to teach them how to build quicker than they already could.
