The gods stared down at the world they ruled and muttered between themselves.
The humans, although short lived, were becoming violent and warred endlessly. It had been the gods’ will that the humans obey and trust their laws and be passive. They had decided not to listen. Soon they may even try and war against them.
It would be easy to snuff them from this existence, but instead the gods decided that a hard lesson would be better.
The gods spoke through a lowly priest, and their words were passed onto the people. All children under ten years of age would be given over to the gods.
The gods decided that this was proper punishment for disobedience. Also, if the humans did not learn, then they would at least have new willing and young students to teach.
