Thrashers are relatively primitive creatures. Specifically, they are an offshoot of the Ogryn race that never had an opportunity to progress to the point of some of their kin. As such, their society is functionally non-existent. Thrashers live in the cold caves of the Mountains of Despair, either alone or in small family groups and will ruthlessly attack anything and anyone they come across.
Though possessing primitive sentience, few are intelligent enough to truly comprehend the world beyond their hunting grounds. Fewer still will be able to communicate with other beings and not try to smash them with the nearest rock.
