After moving through the travel tree the Wind spirit horde began moving into former Fire iron land, a land that had been ravaged by the human armies and opportunistic bandit's alike
"Which means that there's still a lot of blood to be had in this conflict… Plus there's the Black oni's to think about too..."
Julie was used to Mike muttering his thoughts out loud like this so she didn't really comment on it this time, Beel however asked
"What about the Black oni's?"
Mike showed a slight smile
"They'll most likely attack once the last remnants of Fire iron resistance have been stomped out by the humans"
"...But why..? Aren't they allied?"
"Yes, but with the Fire iron king out of the way there's no need for them to honour that alliance, instead they will deepen their betrayal of the Fire irons by re-conquering their lands from the humans before they put a puppet on the throne of the newly liberated Fire iron lands"
