The Dragon Masters

Men have been at war for centuries with the reptilian race called "Basics." As conquerors always have, the winners of each bloody encounter have made slaves of the losers-but in this far-future war, each side has improved upon its slaves with genetic engineering. And so at last there came to be two neighboring worlds: Aerlith, where men have raised a race of fearsome dragons to be their servants, and nearby Coralyne, where the descendants of those very dragons are served by strong, savage mutants who once were human. Inevitably, those two worlds would meet in one final contest. . . .
