 Why do the Vegans want the humans to be involved in their political struggle?
UPSTARTS By L. J. STECHER, JR. 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. But here, surrounded by this writhing, slithering mass of eight-foot creatures, he felt distinctly unhappy. These humanoids had large mouths and sharp teeth, and they unquestionably slavered. If they carried out the threats of their present attitude, Earth would have to send Marshall to replace him. His manner demonstrated an elaborate air of unconcern that he felt sure was entirely wasted on these monsters. 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. "And just what business do you have here, stranger?" asked the senior of the guards, his speaking orifice framing with difficulty the sibilances of Universal Galactic. 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. 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.
