Tales to Astonish #70

Namor returns to Atlantis to find that Warlord Krang, eager to conquer the surface world, has taken his throne. Namor spurns the affections of Lady Dorma who, despite loving him, turns him in to Krang. Namor is arrested and imprisoned as a traitor. Realizing that the only thing that will allow him to regain his kingdom and his subjects is to acquire the long-hidden Trident of Neptune, Namor escapes, with the help of Dorma, and goes to recover it. Neither Namor or Dorma realize that Krang has set a trap for him.
