The Machine is a location eight hundred feet below the Utah Salt Flats, where the United States of America's armed forces work on creating very high-tech weaponry. Initially based on the technological principles brought with Wraith's arrival in November of 1938 as a research project by General William Rudolph, it eventually developed into a black operations military outfit that used highly advanced technology to neutralize threats to the United States and the free world in general, doing so efficiently for decades. The only people who know about the Machine are the President of the United States and a few other "white hats." The executive branch gives intelligence to the Machine, who act on it and come back with whatever results, with minimal interference.
Weaponry produced included black hole lasers (max-graviton-photon-emitters) and black hole bullets (50 caliber rockets with light vacuums inside of them).
