The Vector Sigma Chamber is a large, circular area, bathed in an intense radiance emanating from the center of the room. When active, Vector Sigma itself glows like a yellow star, almost too intensely to look at without heavily-shielded optics. The walls of the chamber are blue steel, seeming untarnished, unlike the tunnels surrounding the chamber. Some say Vector Sigma contains the essence of Primus, and all but the most jaded of Transformers would feel awed to be its presence.
