Fictional character biography.
Sardath is the lead scientist on the technologically advanced planet Rann. The Rannians are a humanoid race who appear almost identical to humans from Earth. Sardath is known for many of his world's greatest inventions, the most important being Zeta-Beam. It was originally created as a communication device so he could contact other worlds; due to the amount of energy used, it became a teleporter. The first planet reached was Earth, where it struck one of the world's native archaeologists, Adam Strange, and then transported him across the galaxy to Rann. Sardath was shocked by this, but theorised that radiation of the beam would wear off, sending the Earthling home. The alien was shocked to find himself in Sardath's lab; he calmed down when he met Sardath's daughter, Alanna. 
The Earthling remained with Sardath and his daughter to protect the planet from extraterrestrial threats using Rann's technology. Eventually, the effects of the beam wore off, automatically returning Strange to Earth at the exact point of departure, but not before Sardath had given him a schedule of beam firings, allowing him to periodically return to the planet. Using mathematical calculations, he was able to determine the exact time and the precise locations at which the Zeta-Beams would arrive. He travels the world and intercepts them, to defend Rann and be with Alanna.
