 What likely happens to Crownwall after the story is over?
The sight of an Earthman on Vega III, where it was impossible for an outlander to be, brought angry crowds to surround John Crownwall as he strode toward the palace of Viceroy Tronn Ffallk, ruler of Sector XII of the Universal Holy Empire of Sunda. He ignored the snarling, the spitting, the waving of boneless prehensile fingers, as he ignored the heavy gravity and heavier air of the unfamiliar planet. John Crownwall, florid, red-headed and bulky, considered himself to be a bold man. But here, surrounded by this writhing, slithering mass of eight-foot creatures, he felt distinctly unhappy. Crownwall had heard about creatures that slavered, but he had never before seen it done. If they carried out the threats of their present attitude, Earth would have to send Marshall to replace him. And if Crownwall couldn't do the job, thought Crownwall, then it was a sure bet that Marshall wouldn't have a chance. He climbed the great ramp, with its deeply carved Greek key design, toward the mighty entrance gate of the palace. The clashing teeth of the noisiest of them were only inches from the quivering flesh of his back as he reached the upper level. Instantly, and unexpectedly to Crownwall, the threatening crowd dropped back fearfully, so that he walked the last fifty meters alone. A pair of guards, their purple hides smoothly polished and gleaming with oil, crossed their ceremonial pikes in front of him as he approached the entrance. If you know what's good for you, you'll get out of here while you can still walk. "Just tell him that a man has arrived from Earth to talk to him. Crownwall sat on the steps, puffed alight a cigarette, and blew expert smoke rings toward the guards. An elegant courtier, with elaborately jeweled harness, bustled from inside the palace, obviously trying to present an air of strolling nonchalance. His Effulgence commands you to appear before him at once." The two guards withdrew their pikes and froze into immobility at the sides of the entrance.
