The Emperor could have simply sent them to the grasslands to be enfeoffed, creating countless minor nobles and turning the grasslands into a heap of loose sand.
A great noble would act like the eye of a storm, drawing in the minor nobles around them, but a swath of minor nobles could only ever be a heap of loose sand.
At that point, the Emperor's power would return to its zenith. His Control Power over the grasslands, and indeed the entire empire, would reach its peak, and no one would be able to shake his rule.
The negative effects of the previous western rebellion, the war in the Northern Lands, and the Alien Race invasion in the southern deserts would all be minimized.
In that case, everyone would be happy. The music would play on, the dancing would continue, and Caladia would still be Caladia, filled with revelry night after night.
