"We're needed here," he told her, his voice pleading for the understanding he couldn't yet fully give himself. "These people need as rich a set of bloodlines as possible to give the new race strength. The fifty men and women on this ship will be needed to start them with a decent chance.

"No," he told her. "Replenish the stars."

Some day, the whole universe would be a spawning ground for the children of men!
