A) A super-nation is our generic term for super-large nations composed of several nations, i.e. the Union and Confederacy. Super-nations generally have utterly vast amounts of land (often comprising tens of thousands of worlds and smaller countries). For the most part nations or sub-nations within the super-nations retain most of their original systems of law and order so long as they're generally alligned with the super-nation's goals and ideals - however, there are always some differences, such as unified currency and the like.
