Aotujai Ul-Tash

Aotujai Ul-Tash (sometimes spelled Atujai) was the fifth recognized son of Torkai Ul-Tash and one of the most prominent generals in his father's great wars of conquest. After Torkai's death in 930 CV, he, along with his elder brothers Kirdai and Tovaan, received the title of Ul-Tash in his own right and was given rulership over one of the three major states into which the All-Conqueror's domains were divided. Aotujai received the central portion, comprising all of Suagirea proper and the various peripheral territories below the vantagelands of the high steppe; this was called the Aotujan Empire after his own name.
Aotujai's empire would prove to the most short-lived of the three Torkaian successor states. In 939 CV, Aotujai mustered his armies and launched a renewed attempt to conquer the Phyridian Empire to his southeast, which had stubbornly held out against Torkai himself even as all the lands of Urem beyond were subjugated. He had no more success than his father, and was conclusively defeated at the Battle of Shamach in 945 CV. This loss was so devastating that Aotujai lost the confidence of his generals and warlords, and the many tribal groups that made up his armies. His renown was tarnished beyond reparation and the steppe warriors no longer believed that to answer his summons was to ride to victory. 
Despite strenuous attempts to reassert his authority, Aotujai's empire disintegrated over the next decade. His decrees were ignored and excuses were made by those called to send tribute, who previously would have dared not defy him. Fewer and fewer men would muster to his banners. The tamirs who had been his vassals began to look to their own people's affairs again, as their forefathers had in the old days. By 955 CV, a Suagirea that was unified under Torkai had collapsed back into a shifting, fractious patchwork of independent tamirates and tribal chiefdoms. 
In that same year of 955, Aotujai gathered all his sons and relations, and all the warriors he could still muster to his banner (scarcely two thousand men by that point) and led them on a suicidal last raid deep into Phyridian lands. They ravaged a swathe of the frontier before being finally intercepted and wiped out to the last man near Vitra. Aotujai himself and his sons, it is said, were slashed to mincemeat by a wall of spectral swords conjured by Phyridian battle-mages. Thus perished the fifth son of Torkai, bereft of his empire and denied even a warrior's death by honest steel.
