Aretai(noun) a major tribe of the Tahari, their vassal tribes are the Arani, Luraz, Ravir, Tajuk(s), Tashid, Ti, and Zevar. Their war cry is 'Aretai Victorious!'.
To my right were the lines of the Aretai. The Aretai themselves, of course, with black kaffiyeh and white agal cording, held their center. Their right flank was held by the Luraz and the Tashid. Their left flank was held by the Raviri, and four minor tribes, the Ti, the Zevar, the Arani and the Tajuks. The Tajuks are not actually a vassal tribe of the Aretai, though they ride with them. More than two hundred years ago a wandering Tajuk had been rescued in the desert by Aretai riders, who had treated him well, and had given him water and a kaiila. The man had found his way back to his own tents. Since that time the Tajuks had, whenever they heard the Aretai were gathering, and summoning tribes, come to ride with them. They had never been summoned by the Aretai, who had no right to do this, but they had never failed to come.

I had failed to contact them in Kasra, as I had planned, but I had learned that they were in the region of Tor, purchasing kaiila, for a caravan to the kasbah, or fortress, of Suleiman, of the Aretai tribe, master of a thousand lances, Ubar of the Oasis of Nine Wells.
