Sebastian Wolfe was a scientist who worked with the First Sons on the Ray Sphere project. He was, at the time, close friends with Kessler, for whom he extensively researched technologies that could utilize Ray Field energy. Wolfe also created the Ray Field Inhibitor, a device to counter the effects of the plague. He later gave the RFI to Cole MacGrath, and had intended to work with him to combat The Beast. Unfortunately he met an untimely demise at the hands of Joseph Bertrand III.
