So one thing that has always confused me, and no amount of researching I have done has turned up an answer to this question...
What is the difference between the Imperial Security Bureau, and Imperial Intelligence?
They seem to exist to do the same thing however I like to be accurate in how I include such organizations in my game.
At a guess, it sounds like the ISB mainly deals in spying with political entities and enforcing local laws, such as catching smugglers and the likes, while Imperial Intelligence actually deals with Military related spying and operations.
