The Potent Anger Dust was something that Sol had created solely to piss off the Skymaster Hawk.
He knew that he didn't want its presence to be erased since it was going to battle later on, and that could complicate things.
It was unnecessary, so Sol wanted to completely take that option out of the picture.
Most of the Potent Anger Dust was inhaled through the nostril on the beak of the hawk.
The rest stained its face and eyes and also flew into the wind--not touching any of the Mercenaries.
But, they were already pissed the hell off, so it wouldn't have mattered much either way.
The Skymaster Hawk screeched loudly, sending its message across the taiga.
Everyone held on tightly, as the hawk suddenly dove down toward the ground and began its journey toward its rival.
In nature, a demon beast having a rival in a certain plot of area was normal.
