At last it was settled. Then Thane committed his treason. He told all he knew, about the second-stage drive and the tracer, and when Astrid came in, she finished the job. Between them they gave away the most important secrets of the Galaxy to an enemy, a man of endless, pathologic ambition. * * * * * Candar, of course, wanted confirmation. It was fast in coming. With all the technical resources of Onzar at her disposal, Astrid had a prototype of the tracer in operation the following day. An hour later the existence of a ship using the catalyst drive was reported by the tracer. Its position could not be determined until a base line had been established. The following day, three more tracers were set up at widely separated points across the planet. More movement of ships was reported--and they were definitely placed within the Darzent Empire. One more day passed, and more tracers had been set up on Onzar III, across the sun from the capitol planet. At the same time, Candar pushed work on the second-stage drive with all possible speed. As Thane had guessed, the use of gold in the catalyst principle gave Candar pause, but only momentarily. It was true that such a use of gold violated one of the oldest and strongest taboos in the religion but Candar's hunger for power was stronger than his fear of revolt. As Thane had supposed, Candar went ahead with the development of the drive, thinking that when he had it his power would enable him to ignore the church. The church was powerful on just this system. With the drive, Candar would rule the Galaxy. Candar had taken certain precautions. Almost complete radio silence had been clamped down, partially to prevent any information getting out, and partially to provide enough power for the tracer. No ships of any registry could enter or leave the system. Only his personal adherents of unquestioned loyalty were allowed to work on the assembly of the drive. But there were leaks. And there was Thane.... With one legal pretext after another, Candar had succeeded in keeping Thane in isolation within the palace for three days. Finally, he gave in to the demand of the church that Thane be turned over to the Cathedral. He did not want Thane loose but still he could not afford a break with the church just a few days before his great victory. So Thane at last managed to see Selan in her personal chambers in the Keltar Cathedral. It was a small, comfortable room that did not seem to share the bleakness of most of Onzar. Perhaps, as much as anything, that was due to the personality of the Priestess Selan. She was very old. She had remained slim, and her lined face retained much of its original golden color. Her yellow eyes were alert. The only term Thane could think of for their expression was cynical compassion. She sat by a small writing table in one of the traditional, intricately carved chairs of Onzar.
