Namor and Namorita continue their fight against Doctor Hydro - as the villain attacks Atlantis! Plus, an untold tale of the ancient history of Atlantis!
This book also contains another story, the first "Tales of Atlantis." These stories relate the origins of sunken Atlantis, although this one is set in the Hyborian age between Kull and Conan, and deals with pre-Cataclysm Atlantis. It is scripted by Steve Gerber, co-plotted and penciled by Howard Chaykin, and inked by Joe Sinnott. King Kamuu, Queen Zarta, Ocar, and Zapal are the characters in this story.
Both the Atlanteans and the Lemurians, while air breathers, are colored blue in this story. I'm not sure if that is a colorist mistake, or not.
