George Leicester was a medical doctor from England who was working in the Philipines, when he helped to resuscitate a Hindu yogi named Nadir Kritchna, who had been sentenced to electrocution for a crime he clearly did not commit. The grateful Kritchna saw in Leicester, a man pure of heart and destined for great things. Kritchna takes him to a mysterious temple in the jungle, and performs various mystic rituals to grant the doctor supernatural powers, certain he will never misuse them. Leicester adopts the name "Fascinax" and wearing a hat and cape, sets out on a quest to fight evil, starting with Kritchna's green-eyed nemesis, Numa Pergyll (who possessed powers rivaling those of Fascinax himself) and his henchman, Franz Krypfer.
