timeline, when this human speciation has exploded? I envision all these different aliens that were once us.
I've thought about setting a story in another era, but these are ideas without characters and if it doesn't have a character it's not a story that picks up and runs. The Miles universe is presently snagged on Miles. He's such a pivotal character, such a world-changer, that I don't know where the universe goes after him—unless I jump so far ahead it becomes a matter of indifference whether he lived or died. Which is a rather sad notion.
More people ask about whether Ivan is going to get married than how human evolution is going to go ten thousand years down the timeline (although, when you think about it, the two questions are profoundly related). We see Ivan a lot through Miles's eyes, and Miles is . . . opinionated, let's say, but beneath Ivan Vorpatril's lazy facade is a real lazy man. When we finally saw Ivan through his own mind, as a viewpoint character in A Civil Campaign , some people were disappointed because there wasn't more there. They had constructed Ivan as this man of mystery.
But the Ivan that you see is pretty much the Ivan that you get. He could be challenged, and he would rise to the occasion. Without the challenge, he would just lie there. Nothing is more life-disrupting for a hapless character than to accidentally stumble into one of my books. When I was writing A Civil Campaign and it was time for one of Ivan's scenes, I always had the feeling that he was hiding out from me much the way he hid out from his mother when she had unpleasant chores for him. He whined pitifully whenever I dragged him back onstage. Clearly, I'll have to think about something special for Ivan. He'll hate it, but he doesn't get a vote.
Addressing some of the more common general questions about the Vorkosiverse's roots: Miles's world, Barrayar, is steeped in Russian culture, while their rivals the Betans are more Californian. It was likely my Cold War milieu that inspired me to create a world peopled by the descendants of Russians—plus, it must be admitted, the lingering influence of The Man from U.N.C.L.E. 's most personable hero, Illya Kuryakin. When I started the work in late 1982, it looked like the Cold War would go on forever. But in a moment of canny something-or-another—I know it wasn't foresight—I did not make my future Russians necessarily descended from the Soviet Union. I was more strategically vague than that, which put me ahead of the curve when the Soviet Union fell in 1989.
Vor society is not based on Soviet society. Its Time-of- Isolation social structure had devolved to a species of neo-feudalism, for the same reasons of poor communications that the original feudalism evolved to address. I've selected bits and pieces of social inspiration from sources as diverse as Meiji Japan, Imperial Russia and Germany, and whatever other historical sources came my way, building up my own mental picture about how the real world, and therefore fictional worlds, work.
I don't know whether the planet is called Barrayar in honor of the ruling family VorBarra or vice versa. I make up my backgrounds as needed for the tale I'm writing, and I don't fix the details until they are needed (they might, after all, need to be something else). So we won't find out until I set a tale in an earlier period, which doesn't look likely to happen any time soon.
Whether the Galaxy common language is English or not depends on the region. In Miles's neck of the woods, it appears to be English. Some English-descended dialect may be the interstellar lingua franca the way English is the language of international air traffic, for the same practical reasons (it got there first, everybody needs to be able to communicate with everyone else for safety reasons, whatever). I haven't explored the probable effects of really good automatic/computerized real-time translations that we may presume would be developed by then, except in
