Very interesting, Grinder, thanks very much for that link. I know I'd run across that legend before, and certainly I've known about and been a fan of Emperor Ashoka (another one to add to the "who would you visit with a time machine" list) for a while. But hadn't made the connection. That would make a really, really nice arc through human history if it were the case. And you wouldn't need immortal aliens as part of the scenario of it was a "multi-generational project..."
