Man Uses Dust and he gets power in one form or another, But you don't get something for nothing. So what is the down side? The pollution from Dust use is the building blocks of Grimm. It travels like smog following it's own particular rules untill it becomes concentrated enough to spawn Grimm. If they are killed they disapate back into the smog. If they live they get stronger and smarter they learn to ignore the instinct that pulls them to humans and death. The more man uses Dust  more Grimm are spawn just a few growup and learn and wait. A monster version of global warming.
