Something that caught my curiosity with the new lore thats being developed, how big is the universe/territory in ES2? I mean there are some quotes in heroes histories and planet descriptions which talk about trillions yet in game we can only play with 50 - 60 system which would mean that each planet would have extremely high population even gas giants! so i thought that maybe the territory is actually far bigger but due gameplay is impossible to control thousands of worlds am i right? or wrong ? 

What made my think about this was the following picture ( spoilers maybe ? ) 

When it says that we clean an entire arm of  the galaxy it means all of its system ( a huuuge feat for the cravers) or just the 2 or 3 systems there or maybe something in between like a couple of hundreds/thousands of worlds? 

Thanks for the asnwers!. 

I believe it is an abstraction.

You are asking questions to obvious answers. A galaxy of 50-60 stars is no galaxy. It's a scale at which players can still manage individual systems, yet enjoy the temp of the game.

Just as with Augaria you don't play on the entire planet and don't even represent the entire faction but often a character split off for whatever reason. You only use a part of the galaxy to do your thing just as much.
