Sphere of Control

I was reading some very dry program documentation and I stumbled across the phrase "sphere of control." That's Sphere of Control. As in, I have the Sphere of Control and I shall rule the world! Bwa ha ha ha ha! I picture the Sphere of Control about softball size, constructed of blue and black swirling light. It hums a little. I really need to find this Sphere of Control. Lately, I feel very out of control. Obviously, I've misplaced my sphere.
