"On July 16, 1945, the Manhattan project reached fruition. The first atomic bomb was detonated at the Trinity Site near Alamogordo, New Mexico. The explosion ripped a hole in the fabric of space, and Dr. Oppenheimer's words '... I am become Death, the destroyer of worlds' unknowingly closed a necromantic ritual. The fireball vanished, but the mushroom cloud remained."
