Unlike the conquered tribes or the subdued tribes, the Khan did not kill the chief or the influential people of the west
Instead, it seems more like he had reached some kind of understanding between them. Aeryon wanted an intact west.
Unlike any other rulers that would surely kills all of the chief and all of those influential people when he gained power, the way Aeryon sees the world is different from them and the ambition he wanted to achieve could not be achieved by devastating the west.
It is also probably of this reason that the Chagai chief could convince the Ultar tribe and the Nergui tribe.
Ultar tribe was badly devastated by the attack from Burchu and Mukhulai and it is not an exaggeration to say that all of the gains of the Ultar tribe that they have gained with the expansion of the tribe nearly all squandered in one battle
There was a sense of impending doom before.
