Lone Earthman on the vivid and intricate world of double-sunned Antares in Scorpio, Dray Prescot had been the pawn of the unseen Star Lords who had seeded that planet with the offspring of a hundred alien races. But at last Prescot had come in sight of the goal which he shared with these space masters -- the overthrow of slavers and their evil empires On the island kingdom of Hyrklana his course now seemed clear. Overthrow its decadent queen, lead rebellion against the cruel Arena, and free the princess who was its rightful ruler. It was a hard task, but for Dray Prescot against whom sorcerers and swordsmen had contended, it was the only course he could follow. Though it might this time lead to his death, there could be no turning back.
