Parads looked like large earwigs, though it was politically incorrect to refer to them as such. They were members of the Galactic Federation and served as surveillance technicians. They were well adapted to jobs that dealt with sound, being a telepathic and sensitive species. They could also detect psychic storms, which meant they had to try to stay away from situations that might cause psychic storms.
In 3999, when the Wirrn queen telepathically contacted all her servants, all the Parad on Micawber's World and on neighbouring world were killed when their brains shut their bodies down to try to survive the telepathic message. (PROSE: Placebo Effect)
