Kul'Cha'Vir was a location on Vulcan and was located in the Tat'sahr province.
Noted as being a small and secret monastery which only appeared in the older manuscripts. It was devoted to training those Vulcans who had a special psionic ability which related to pyrokinesis. As such, the name of the monastery translates from old Vulcan to mean "Brothers of Fire". Scientists were generally unaware of what was found there but believed that there were lost knowledge or training techniques involved. Both the Academy of Sciences and the Vulcan government often politely requested to see anything that was brought back by any expedition that went to the area. They also controlled what information escaped the area in order to prevent anything dangerous from falling into the hands of the Vulcan Isolationist Movement.
