Indrahar was one of the nations of the Free Era. It was located in the northwestern area of the Westlands. To the west was Abayan, with Basharande to the north, Oburun to the east, Masenashar to the southeast, and Oman Dahar to the south. Eventually, this area of land became what is now eastern Arad Doman, near the northern most end of the Mountains of Mist.
By FY 963, Indrahar had fallen to Hawkwing.
