On a distant planet, the Chosen are a faction of the superhuman populace possessing what they consider a genetically perfect form. Status among the Chosen comes from how perfect their appearance is judged to be. Living in cold and sterile cities, they consider human contact taboo and reproduce through artificial genetic mingling procedures. A subsect of Chosen are the Dualers, who each possess a secondary imperfect form. Although still considered to be among the Chosen, the Dualers are openly treated as second rate by their fellows.
