After receiving such a clear threat from the Emperor, the investigators naturally are filled with fear. This was the Emperor! He was above everyone in the Empire!
How could these lower ranking Nobles not feel fear when the Emperor is clearly showing his dissatisfaction with them
As investigators, they managed to amass power more than they should have with their lower titles
However, that power they have is something they have only because of the Emperor!
If they were to ever fall out from the Emperor's favor, their power would also vanish
No matter who looks at the Emperor's plan, they all would praise it
He can use the investigators as sharp knives against the Nobles but these sharp knives can only bare their sharpness to any other person than the Emperor!
The way that Javier handled the investigation department is indeed worthy of praise. Even someone like Keon has to give his father that!
"W-we were wrong"
