Synopsis for "Tales of Atlantis: The Sword in the Throne!"
Kamuu enters the ruins of Atlantis where he unsheathes the sword of the long-dead emperor to fight off the demon that pursued him. Upon presenting the sword, the skeletal demon bows in obedience, stating that it had not recognized him, but before Kamuu can question it he falls over in a daze and awakens in a vision. In this vision, he is met by the spirits of the Kamuu and Zartra from before the fall of Atlantis. They share with him that he will be a great king and that the steps he takes now will lay the groundwork for an even greater king and Atlantis. When he awakens from his vision, Kamuu claims the ruins of Atlantis as the place where he will build the new Atlantis. While doing so, he is met by Zartra, the daughter of Queen Elanna, Kamuu's sworn enemy and the slayer of Kamuu's father. Zartra explains that she's not there for battle and that her mother is a seer who knows Kamuu's destiny and hopes that Zartra can make peace with him in order to unite their kingdoms. When Kamuu agrees, Zartra suggests that they throw down their swords in friendship "and perhaps...more than that." And thus the first book in the eons-spanning saga of Namor's undersea realm concludes.
- This issue's letters page printed a letter from a reader asking why the surface people in the "Tales of Atlantis" story in Sub-Mariner #62 were blue-skinned. The editorial reply was that Kamuu and Zartra were blue-skinned for "the most ridiculous reason of all: a colorist’s error that we simply did not catch until we saw the proofs of the first Tales of Atlantis story – at which time it was too late to change the second episode!"
- The presence in this issue of the explanation for that coloring error did not prevent that mistake from being repeated since, when the original Kamuu and Zartra appeared in this issue's Tales of Atlantis as spirits, they were again depicted as blue-skinned.
