Illsombreh Tisroc was a ruler of Calormen, probably sometime in the late 9th century (Narnian time). He was the son of Ardeeb Tisroc, who claimed to be descended from Tash himself. He had at least two sons, one of whom was named Kidrash Tarkaan. Illsombreh was the great-great-grandfather of the Tarkheena Aravis.
