“Secret of the Eternal City!”

Zapped by the zeta-beam, Adam is teleported to Rann, where he is captured by primitive tribesmen, who believe their “Rainbow Doom” device will execute him. However, the device is actually a teleporter which sends him to Rann’s sister planet Anthorann. He meets Alanna and Sardath, who had used knowledge from Samakand scientists to journey to Anthorann, but crashed. Adam dons a Rann spacesuit from the wreckage and faces invaders from Morleen, who swing a "diamondium" pendulum to cut open the dome of New Ranagar. Adam ray-blasts the shaft, inducing the aliens to flee, then fades away to Earth.
