Nasu are Small slug like Symbiotic creatures that inhabit and animate the corpses of larger lifeforms. Many of the tribe distrusts the Nasu believing that they kill superior specimens to inhabit their bodies; this couldn't be farther from the truth as the Nasu are pacifistic, and due to their religious beliefs strive to never kill another sentient being.

Nasu favor long coats and deep hoods; slick shiny clothing made of synthetic materials and vinyl's.
