Synopsis:
When Adam Strange returns to Rann using the Zeta Beam, Alanna takes him to visit a sinking island where they encounter several giants. The giants are Rhollians, an alien race which is affected by the metal Orichalkum. The presence of the metal is the galaxy has caused their race to grow, and it will eventually kill them. The aliens have found Orichalkum on the island and plan to sink it as they did ancient Atlantis. With the island and the Orichalkum underwater, it cannot affect them.

Adam and Alanna are briefly captured, but escape and lead the Rhollians on a chase across the island. The island begins to sink, as it does on a regular basis, convincing the aliens that their work is done. They leave the planet, and Adam and Alanna are rescued. Alanna plans to send a ship after them to insure they do not return.
