Voicing a thunderous roar, Sadu sprang.


Racing across the plains and through the jungles of a savage world, moving with unflagging swiftness by night and by day, came Tharn, mighty warrior of an era already old twenty thousand years before the founding of Rome—an era which witnessed the arrival to recognizable prehistory of the first true man.

Somewhere to the south of this Cro-Magnon fighting man, separated by endless vistas of primeval forest, grass-filled plains and towering mountain ranges, were the girl he loved and the men who had taken her.

Still fresh in Tharn's memory were the events of the past few weeks: the battles in Sephar's arena; the bloody revolt engineered by Tharn and his friends; the arrival of his father and fifty warriors of his tribe; the ascension of his close friend, Katon, to the kingship of Sephar; the finding of his own mother, long given up for dead after disappearing from the tribal caves ten summers before; the stunning shock upon learning that Jotan had taken Dylara with him when he and his party of fellow Ammadians began their journey back to far-off Ammad, mother country of a civilization and culture far in advance of the Cro-Magnon cave dwellers.*

The thrust of a knife from the cowardly and treacherous hand of Sephar's high priest had come near to costing Tharn his life on the eve of his departure in quest of Dylara. As it was, an entire moon passed before the caveman was able to leave his bed.

Pryak, the high priest, had died horribly in payment of his treachery; but Tharn suffered a thousand deaths from enforced idleness while the girl he loved was being carried farther and farther from the one person who possessed the ability to effect her rescue.

And then, over a moon ago, Tharn bade farewell to his mother and to the father whose name he bore, and plunged into the heart of the unfamiliar territory south of Sephar, taking up the trail of those Ammadians who held Dylara.
