Derriphan
these nightmarish creatures were born of the Dark Side of the Force, and were named for the Sith word meaning "devourer." These creatures consumed the very thoughts and experiences of living beings, leaving behind the bodies without the living essense they once contained. In order to feed, however, a Derriphan had to enter the body of its victim, take control of the victim's mind, the drain off the essense of the victim. These creatures were believed to have been extinct, having died out after the Great Sith War. However, a few Derriphan managed to survive the battle, and existed during the Galactic Civil War. Those who claimed to have actually seen a Derriphan said that the creatures resembled miniature black stars, roiling with energy.
