The displaced soldiers are much more willing to listen to the words of the beastkin elders than they were to believe Cain. Their age gives their words a sense of truth that someone young enough to be an enemy soldier didn't have.
That brings them to a unique problem. Most of the nations that they used to belong to no longer exist, and their families are multiple generations removed from them, plus without a system in the Awakened zone, even getting home would be an adventure. If Cain is going to try to fix any more of the vortexes, they are going to have to consider what to do with the people who come back out.
