Aotujan Empire

The Aotujan Empire was the central one of the three huge states into which Torkai Ul-Tash's enormous domain was divided after his death in 930 CV. It comprised Suagirea itself, the homeland of the All-Conqueror and his warriors, along with various peripheral territories below the vantage-lands that mark the edge of the high steppes. Rulership over this empire was given to Aotujai Ul-Tash, fifth legitimate son of Torkai.
The Aotujan state was short-lived. In 939 CV, Aotujai Ul-Tash launched a renewed attempt to conquer the stubborn Phyridians to his southeast, who had successfully resisted Torkai himself when all others were forced to submit. He had some early successes but was decisively beaten at the Battle of Shamach in 945 CV; as under Torkai, Suagir steppe riders proved formidable on the open field but had nothing that could match Amran's battle-mages. So discrediting was the defeat to Aotujai's renown, and so heavy were the losses suffered by his armies, that he began to lose control over his empire. Over the following decade, the Aotujan state fragmented back into a disorderly patchwork of independent tamyrates and small tribal domains, as it had been before the rise of Torkai. It took an iron will and an iron fist to keep the whole Suagir steppe unified under a single rule; Aotujai could not sustain what his father had achieved. His empire had lasted only twenty-six years and he had been its only ruler. 
To make matters worse for the sons of Torkai, the breakup of the Aotujan empire showed other subject-peoples that the Suagirs were not invincible. This helped precipitate the Woodcutter's Rebellion in 956 CV, followed by the general insurrection of the Kelimarians against their Tovaanid overlords, which led to the downfall of the Tovaanid state not long after its Aotujan counterpart.
