From my understanding and through what I have witnessed, the adventuring community at large has tried to avoid conflict with the ants. I have not heard of any open attacks from the adventurers or military. I will instruct my people to keep an eye out. We did encounter an ant lion, as did other adventuring parties, which could explain in part, their absence.
