They broke down the defense of the Wall of Yan and then drive straight to Nurshira and broke down that city and they repay a fraction of the suffering that the Yan people have brought to the people of the Steppe
The innocent of the Steppe still screams in anger.
So, even though Aeryon conquers tribes his reputation as a warrior is unblemished. He fought against Yan people, if that is not a hero, then what is?
Dama even with all of his cruelty is also considered a hero.
So, how could Norgai not know that his ability would not let him be able to do whatever he wanted.
He could not fight against the Brolgadhr.
He also could not fight against the Cha Ner Ul alliance.
He could win a few battle here and there but to defeat such a behemoth, even if he sacrifice every single of his men, he doubt that it would change the outcome.
He is not a strategist and he did not have some kind of tricks or way to escape this.
