 What did the Kallerian and the Stortulian have in common?
The aliens came in every shape and form, in all colors and textures—and all of them eager for a Corrigan contract. The name of the planet was MacTavish IV (if you went by the official Terran listing) or Ghryne (if you called it by what its people were accustomed to calling it). He was followed by a roly-poly blue-skinned humanoid from Donovan's Planet, four feet high and five hundred pounds heavy. At the same time, we had turned away a dozen ursinoids, fifty of the reptilian natives of Ghryne, seven Sirian spiders, and no less than nineteen chlorine-breathing Procyonites wearing gas masks. It was also my sad duty to nix a Vegan who was negotiating through a Ghrynian agent.
