This Immortal

...and call me Conrad!" Such was the only comment that Conrad Nomikos would make on his life-history, an enigma that faded out in lost records and obscurity a few decades back. There were those who said he had once had a different name, that of the liberator of Earth, the man who had fought the star-empire of Vega to a standoff. And some even said that he had had other names, stretching back through the centuries....But Conrad wouldn't talk about his past. For the future was at stake now - the future of Earth and her peoples, as the Vegans returned on a mission which would decide for all time the place of Earth among the worlds of the stars.
