Imrathôr was a man of Bellakar who declared himself Izindubêth (Ad.: "Prophet of Truth.")
Imrathôr was a bazaar-trader. In T.A. 842, Imrathôr felt a mysterious summons to journey into the foothills of the Hulja Mountains. He wandered to the tall summit of Urud an-Khibil. He claimed to have beheld a visitation from The One at this location, and to make known the Batân an-Izindi (Ad.: "The Path of Truth") to those who would listen, thus declaring himself the Izindubêth.
By T.A. 850, Imrathôr had spread his message throughout the corners of Bellakar. He returned to Urud an-Khibil with his followers, beginning the construction of a monastery to provide a locus of pilgrimage for those seeking guidance in the Batân an-Izindi.
In T.A. 864 - 865, the battles of Sarnak and Duhu were fought between Izinduists and Hazaj Tollin, and by T.A. 869 they had completed a near bloodless conquest of the realm.
Imrathôr died in T.A. 884.
