A generic blanket-term for non-civilized, non-human, generally subterranean-bred species that inhabit (some would say infest) cave networks and old ruins throughout the Grand Duchy. Alternately called morlocks or goblins, troggs refer to any of a dozen or so species that are actually quite dissimilar to one another and who usually have no mutual alliances (often quite the opposite). The Mountains to the east and north of the Duchy are said to be thick with enclaves of the creatures, where they have formed squalid psuedo kingdoms and roam the rocky lands virtually uncontested -- aside from their internecine raiding and tribal battles.
