Dom is correct. It's a rope-a-dope. The only thing missing is someone killing you when you get there.
Also, there is no point to doing the Empire ranks unless you want the Clipper (available at Baron). None of the permit systems have anything different from any other system. I'm not trying to spoil anything, just trying to save you some wasted time if you were hoping for anything else.
Fed ranks are different though, there are actually some benefits to getting to visit the permit systems.
"IMPERIAL SUMMONS
Greetings, Commander. I am hereby issuing a summons for all your personal attendance at our diplomatic branch in Achenar. Upon arrival, you will receive an encrypted communique from Regional Task Force HQ."
What station in Achenar and I supposed to show up at?
