The Prentara were a sentient species indigenous to the Gamma Quadrant. Prentara were humanoid, having two arms and two legs, a larger skull than humans, and vertical rather than horizontal ribs. They had developed a sophisticated virtual reality technology which tied in directly to their minds. Some time later, Prentaran scientists discovered another existence, a universe of the mind that supported, nurtured and augmented mental activity. They called it the thoughtscape and used it to enhance their VR technology by wiring the equipment into the interface between the universes.
