"Things happened pretty much as people foresaw back in 1981," she said. "The drive was perfected. The ships went out to the nearer stars. They found worlds. They established colonies from the overflowing population of Earth. They found human indigenous races on a few worlds, all of them at a rather low technical level, and they taught them.
"There was a determination from the beginning to make it one universe. No separate nationalistic groups, no chance of wars. The governing council was set up at Altair Two. Every world was represented. There are twenty-nine of them, now. It's expected to go on like that, till there are twenty-nine hundred starworlds represented there, twenty-nine thousand—any number.
