Over the ages, the trogs of this area have at one time or another served as mercenaries for every Garathral city-state. They are unreliable in the long-term, turning on rival tribes and causing more harm than good to the employer.
Trog Run is along the Great Tradeway. The trogs charge tolls for safe passage. Each tribe charges a fee that as a whole is limited by trade treaties with a number of states on the surface and beneath.
