Ogura rebellion was never the endgame for Utgard tribe that Mayeux had crafted, but since it happens, Mayeux take that advantage to kill Garron
So, he had delayed the Kan, and delayed the news from reaching the Kan. And even then, Mayeux plan nearly failed because of the timing.
Because there was one thing that Mayeux miscalculate. And that is Aeryon is not a complete political machine.
Yes, there are many things he could abandon for power. But he was never someone who seek power for power….at least not entirely
If Mayeux thought that, then he is wrong.
Yes, Aeryon wanted power.
Yes, he wanted the Southern Great Steppe.
He wanted to unify it.
And then unify the Great Steppe.
After that, if he succeeds in doing this, whether he wanted to or not, he had to expand because by then, his will alone could not override the wills of the victorious warrior under him
