Unlike most species in Deadstar, Avnauts were not the result of natural evolution, they were instead the first major bio-engineering breakthrough of the Human Verity Project. A sentient lifeform with the design goal of an indestructible worker capable of surviving on the caustic surface of Lau-Tem Pála. 

The Avnauts of Lau-Tem Pála spent their first decades of existence in servitude - living short miserable lives controlled entirely by the companies that owned them. The Nepzerk Revolution brought about the liberation of Avnauts and all workers on Lau-Tem Pála (see Unionism). 

Built to survive the harshest conditions Deadstar can offer, Avnauts are specimens of physical resilience. Their epidermis is composed of thick layers of yellow-grey plasticine-like material that exhibits rubber-like flexibility and chemical resistance. Their entire skeletal structure is formed from a radioactive isotope of cobalt metal, allowing them to thrive amongst high energy radioactivity.
