Twenty year old Edgar J. Hawthorne, son of renowned Edgar R. Hawthorne, Londoner, philanthropist, and world traveler, has always longed for adventure. On a fateful day in the summer of 1835 Edgar gets his wish and is charged with the investigation of the Great Moon Hoax allegedly perpetrated by longtime family friend Johnathan Herschel of the Royal Observatory at the Cape of Good Hope, South Africa. Before reaching his destination however, Edgar is caught up in a centuries old conflict between two warring factions. Due to damages sustained in battle, the airship Stratos, on which he is traveling, crashes into the jungles of the Congo; the very heart of Africa. In his quest to locate provisions, Edgar and a portion of the crew stumble upon an ancient temple and Edgar comes face to face with the embodiment of his deceased sister Ophelia, imprisoned by a sinister figure armed with mind control abilities, known only as the Egyptian. Haunted by his memories of Ophelia, Edgar determines to liberate the the girl whom he now believes to be the reincarnation of his sister, and return her to London. For Edgar's plan to succeed all he needs to do is solve the mysteries of the temple, free the girl, and survive the twisted schemes of the Egyptian.
