The Worgalite race does not originate from Earth. They come from a tri-earth solar system far from our own.
Despite the lack of clothes in this drawing, they are not an anti-clothes species. Worgalites have short dense fur but the fur does not make it uncomfortable to wear clothes or armor. This is the same for the Worgalites on Earth. Earthborn usually feel uncomfortable without clothing because they have spent their lives in their clothed human forms.
