Mevan The'Har

Little is known about the Mevan The'Har. According to classified Vulcan sources, the Mevan The'Har is a psionice weapon, initially used by the desert devils, a sect on ancient Vulcan. While its exact nature is unknown today, it is known that it was responsible for many deaths during Vulcan's civil wars. When the desert devils fled Vulcan on their ship, the Jel'raka, they took the weapon with them, apparently crash landing on the planet Gamma Oreonis II. Traces of the weapon have been found by the crew of the USS Pegasus.
