The war waged on the northern border of Sarth but the initial progress of the Demon Empire was thwarted at key points. The forces that had progressed deeper into the continent found themselves surrounded.
They could not retreat, nor could they advance. They could only die.
They did not die alone. Several mid to high level powers went with them. The stunning number of Sky Realm demons on the Empire side made the supreme powers respond in kind but it was too late to save many.
All in all, 17 smaller sects, 20 large capitals, and innumerable villages or towns had been sacrificed to the war. While some escaped, it was unknown if they could survive the local aether beasts or other dangers being without support could bring.
A few nobles or Elders survived but their status was washed away as their backing was wiped from the world.
