The Camelyons or Rift Ghosts are a nomadic species that live in part of Oralian sector known as the Nothingness and within the gaseous phenomena known as the Great Barrier Rift. The crew of the USS Pioneer encountered them while on a mission to deliver Federation Special Envoy Dr. Lucus Kesar to an Alkanden outpost. (Star Trek: Pioneer: "The Nothingness")
