Language:

Russian / Sovietsky is our language.

We'll simply make it a required second language for 50 years then make their home languages required for 50 years.

In 100 years we'll all be on the same language.

In 200 years everything will have been translated into our language.

You don't want anything to do with those languages. You'll see why later.

So the base is Russian.
