system that links all possible times, places and histories, the chapters that feature the protagonist are all titled "One". Other chapters, titled "Two", feature secondary characters, including original characters, pulp heroes, and real historical characters. The "One" storyline is fairly linear, whereas the "Two" storyline jumps around in time and sequence. After finishing the manuscript, Zelazny shuffled the "Two" chapters randomly among the "One" chapters in order to emphasize their non-linear nature relative to the storyline. Creatures of Light and Darkness, featuring characters in the personae of Egyptian gods, uses a narrative voice entirely in the present tense; the final chapter is structured as a play, and several chapters take the form of long poems. Zelazny also tended to write a short fragment, not intended for publication, as a kind of backstory for a major character, as a way of giving that character a life independent of the particular novel being worked on. At least one "fragment" was published, the short story Dismal Light, originally a backstory for Isle of the Deads Francis Sandow. Sandow himself figures little in Dismal Light, the main character being his son, who is delaying his escape from an unstable star system in order to force his distant father to come in and ask him personally. While Isle of the Dead has Sandow living a life of irresponsible luxury as an escape from his personal demons, "Dismal Light" anchors his character as one who will face up to his responsibilities, however reluctantly. Another common stylistic approach in his novels is the use of mixed genres, whereby elements of each are combined freely and interchangeably. Jack of Shadows and Changeling, for example, revolve around the tensions between the two worlds of magic and technology. Lord of Light, perhaps one of his most famous works, is written in the classic style of a mythic fantasy, while it is established early in the book that the story itself takes place on a colonized planet. Many of Zelazny's works explore variations upon the idea that if there exists an infinite number of worlds, then every world that can be imagined must exist, somewhere. Powerful beings in many of his stories have the ability to travel to worlds that possess precisely the characteristics which that being wishes to experience. (Zelazny characters with this ability include Thoth in Creatures of Light and Darkness, who teleports to these worlds; those with the
