[Creatures of Light and Darkness] is another of Zelazny's velvet fabrics with a warp of Christian, Greek, Egyptian and Norse myths spun into one thread and a weft of macabre fantasy about an order of existence which superposes and controls our own universe. The author manipulates the fantasy of the struggle for power between cruel and vindictive entities of the superposing existence around distortions of the various myths. He thus reveals the starkness of essential life and death. The creatures of this superposed world, the creatures of light and dark, have the quality of the shadows of Plato's cave seen indistinctly and constantly changing. In the end only the individuals in power have changed, not the power structure or the method of using power.
