Captain 

A science fiction series filled with interplanetary adventure, rebellion and mortal combat by the author the The Gorean Saga. Second in the series, The Captain. This is the age of the Telnarians. Their vast, corrupt empire spans galaxies, ruling by terror, slavery, and the lash. But, their corruption and brutality could spell their downfall for, on a thousand worlds of swords and science, the savage souls of true men will not be forever chained. A heroic tide is rising–and one warrior is born to lead the barbarian horde. From the savage death pits of the Ortung Vandals, to the murderous intrigues of the imbecile Emperor’s court, to the perfumed cages of the luscious willing slaves, the giant Otto is carving a legend across the stars. When this gladiator and chieftain of the Wolfung worlds seeks to form a frontier legion of space barbarians, the nobles dare not refuse him; they have only the courage to try to murder him. But can even an empire’s might stop such a man?
