Perhaps this was also why the upper echelons of the third-rate Mechanical Civilization called their own camp "gray"—neither black nor white, drifting beyond any clear stance.
It was precisely this Chaos Neutrality camp attribute that allowed Saine's Mechanical Civilization to strike at both the Homeland Civilizations of this original time-space and the cross-dimensional forces of Dark Universe Time-Space.
