Dama and Aeryon, the two Khans. One control the East and the other control the central region and the west.
Those two Khan probably wanted to fight each other.
They are just waiting for the right time. And they might even coordinate when they are going to fight
These two Khan do love attacking in an ambush or attacking first. After all, these are tribes and not nation and they do not have the need to declare that they are going to war against each other.
It is different when you are a large tribe and you want to attack other large tribe. You do sometimes declare the war beforehand.
This is not to inform the enemy but to unite the hearts of the people in their camp
And even if they wanted to hide, it could not be hidden even more so if they are close. And if it could not be hidden then it is better to declare it and appear magnanimous. At the same time, just because you declare it, does not mean you have to attack immediately.
