There were stories that Quoom dropped early on, probably because other topics suddenly became more interesting to him. "The Enemies of Rome" is more of a story that he continued for a very long time and that didn't really come to an end. But here, too, there is a typical course: In the first part of the story (until the Amazon queen runs into the trap) there is still a clear concept with text and an exciting plot, there is also a Roman commander who pulls the strings (who is later disappeared, the torturers alone determine what happens to the queen - completely absurd in reality!). In the second part, Quoom then raves about various torture ideas, but it's really only about torture, the plot of the story fades into the background and the text to the pictures suddenly stops.
Finally, the sister and priestess is prepared for the execution, the Amazon queen is supposed to watch, there are still one or two image sequences missing until the priestess dies, but suddenly it's over. Quoom must have asked himself how it's going on with the Amazon Queen to fare... and the air was gone.
It was similar in many other stories by Quoom, 'the air ran out for him at some point', sometimes he stopped in the middle of the story, sometimes just before a reasonable conclusion.
