They were the Soul Reapers hanging around in the starship Diablo at the edge of a blackhole in the universe. Souls of humans departed earth at the speed of light and headed for the blackhole as their gateway to the next universe. Most souls gave off coloured light except those that had consumed the flesh of pigs when they where inside a human body or had drank alcholic spirits. The Diablo was fitted with mirrors and lenses that intercepted the souls making voyage through the galaxy. Once a soul had been trapped it would be forced into a titanuim tube that was then sealed at each end. The souls would bounce up and down in the tubes creating energy in the form of heat. These titanuim rods would be sold to starfleet engineers - each new generation of starships required more rods to obtain quicker speeds accross space. The Soul Reapers favourite food was Hiz Lamb from the planet Hiz, this was a slow cooked spiced Lamb curry.
