Yes, I know it is a number of centuries, but how many centuries? 200 years, 300 years, or 4 or 5 centuries? Or has it not been decided yet which century Polaris will take place in?
I believe its intentionally vague, much like the early seasons of the original Star Trek. It takes place sometime in the future, could be a hundred years, could be a thousand.
Dennis may come in and say otherwise though. But that was my impression.
