Certain areas could be understood about how there would be a sudden increase in supernatural activity since it usually had a lot to do with the collective humans and the effects of them always putting out their Life Energy into the world.
It was to most others' understanding that such Life Energy was the cause of such changes, as it would influence how the Spirits would form and grow.
If the Life Energy being released on a large scale was even greater than usual, then that could be a big influence toward it, but that would not always be the deciding factor.
If that was the case, then it was reasonable to say that the threat would soon die down after most humans were reduced during such eras, but such eras did not end so easily or simply.
That meant that there were forces beyond human and Balancer comprehension that played such a role in it all.
