"The Decompressive Isotopic Estrangement Machine was initially designed to be an Exo-Element 1 collector, but an incident led to a design change. During an outdoor test, an assistant accidentally ejected a full capacitor all at once, triggering a shockwave blast that destroyed a military transport and Doctor Vogel's personal automobile. Projekt Endstation saw the device's full potential as a wonder weapon - and the assistant saw the full potential of a firing squad."
