An fwo dur share the majority of their DNA with an extinct armadillo-like creature that used to terrorize the mountainside. Unlike their ancestors, however, an fwo dur stand upright on two legs and reach heights of over nine feet tall. These intelligent creatures tower over the more primitive species in their ecosystem, both physically and intellectually; an fwo dur often use tools, build transient infrastructure, and communicate through disjoint chromatic aberrations which can also cause confusion and dizziness in other species.
