Found on Chameiro the Sjerbit are intelligent humanoid lifeforms that share almost identical genetic makeup to Earth mammals. 

When Humans came to Deadstar, the Sjerbit had yet to create complex social structures, preferring instead to remain close-knit and pack-oriented. Once Humanity brought large scale civilization and technology to Deadstar, many Sjerbit integrated quickly, preferring Human society. Others rejected Humanity, choosing instead to remain “wild.” 

The Sjerbit share traits with their Earth-mammal counterparts. A Sjerbit’s appearance depends heavily on the environment they evolved in and the roles they serve within it (i.e. the Sjerbit of the arid regions of Chameiro tend to be thin, furry, and dessert-fox-like while the Sjerbit of the cold climates of Chameiro are typically wooly and light in coat to camouflage themselves in snow). The inter-species variation of Sjerbit types is among the most diverse in the Deadstar system.
