Rann

History

 * A series of atomic wars plunged the planet of Rann into a Dark Ages. Countries degenerated into warring city-states and the ambient radiation left behind from the wars rendered most of the male populace sterile. The citizens of Rann came close to the brink of extinction.
 * Rann's leading scientist, Sardath, developed teleportation technology known as a Zeta-Beam and used it to transport the Earth archeologist, Adam Strange, to Rann. It was Sardath's hope that Adam would mate with his daughter Alanna, and that the couple would produce offspring.
