Natives of Rann, known as Rannians, are for all intents and purposes the same as Earth-based humans. However, years of reclusive living and apathy brought on by reliance upon their technologically advanced machinery resulted in a society which had stagnated. While entirely apt to continue for some time, Rannians found their gene pool to have deteriorated, resulting in a sterile culture. For decades, no children were born, until Adam Strange fathered a child with Alanna, daughter of Sardath, the man who invented the Zeta Beam. Their daughter, Aleea, remained on Rann with her mother.
