The Vallian Cycle

...Kregen is an Earthlike world, but strange, far stranger than ours. For it is the scene of conflict between galactic powers who utilize its human nations and its astonishing variety of humanoid people as their battleground.

Dray Prescot of Earth has been a tool of those powers - but courage and ingenuity had won him a high role in the Vallian Empire and a certain independence of his own. Thus when a mysterious monster cult began to undermine the empire and when his own beloved princess became a victim of those schemers, Prescot had to go into action.

Somewhere in the unmapped regions of Kregen,... lies the hidden city of the Savanti. The Savanti were the ones responsible for tearing Dray Prescot away from his native Earth for their struggle against the Star Lords.

And Dray had long sought the locale of his original landing because it would help solve the mystery of his transition. Now the time had come when the search must be completed without delay - for the father of his beloved Delia was a victim of assassins, and only the Savanti could undo the evil that could shatter all that Dray held dear in his second planetary homeland.

Dray Prescot ... had arisen high in the empire of Vallia, but luck could not always sustain him.

When, at last, all the forces opposed to his lands, his princess, his emperor, and to him personally converged, it was to produce the darkest hour of his long career. For treason struck at the court, while rebel armies marched from the backlands, the war fleets of enemy nations were aloft, and the uncanny wizardry of a master scientist launched a spell of doom for all Prescot held dear.

With his back to the wall, Dray Prescot faced that time of peril with unflinching will...until the cruelest blow of all was struck: his warrior- daughter Dayra rode in the vanguard of his foes!

When you're down there's no place to go but up. That's the way the brave think and if there is anyone on two world braver than Dray Prescot he has yet to appear.

Because Prescot, who had been a seaman and soldier on distant Earth, and now, on Golden Scorpio's fabulous planet, was claimant to the fallen throne of a conquered empire, would never give up.

Single-handed, if need be, he would be a deadly threat to the enemies of Vallia. But as hw set out on a liberation mission incomparable in the history of two worlds, he knew he would never be alone. There were always the mysterious Star Lords to watch and speculate upon his fate...
