History:
Technologically advanced civilization from the Delta Quadrant. The Malon economy employed an antimatter
power generation system that yielded large quantities of toxic antimatter waste, which was jettisoned into a region of space informally
known as the Void, through a spatial vortex. It was not generally realized that the Void was home to a sentient species of night beings
who were being poisoned by theta radiation from the six billion isotons of toxic antimatter being dumped there every day. The practice
ceased in 2374 when the crew of the Federation starship Voyager sealed the vortex, forcing the Malons to seek alternative energy
technologies for their society. VOY "Night" ; Star Trek Encyclopedia III .
