Weapon From Beyond, The (Starwolf)

Morgan Chane was an Earthman by parentage, but he had been born on the pirate-world Varna, whose heavy gravity had developed strength and incredibly quick reflexes in him. When he was old enough, he joined the raider-ships that looted the starworlds, and fought side by side with the dreaded Starwolves of Varna. But then there was a fight among them. Chane killed their leader, and the other Starwolves turned on him. He barely got away alive - wounded near death, his Starwolf pursuers following him across the galaxy. And there was nowhere he could seek refuge, for no world would lift a hand to save one of the hated Starwolves.
