The New Men are the result of Wyndham's first experiments in accelerated evolution. When Wyndham learns that Wundagore Mountain (on which his advanced genetics research citadel was based) is the prison of the powerful demon known as Chthon, he decides to train his creations in chivalry and battle tactics so that they can oppose Chthon should he ever return. He equips them with advanced weaponry and armor, and gives them flying "atomic steeds" on which to ride (He is assisted in this endeavor by the ghost of the 6th century magician named Magnus).
