Okay sorry Cale. I'm basically a SW wiki. Sometimes I forget others may not know the things I do. So Definitions...

NRI - New Republic Intelligence
IIB - Imperial Intelligence Bureau

There is also the ISB(Imperial Security Bureau) which is more like the Secret Police of the empire. I would make more since for my characters to be ISB if I go empire as it is typical for ISB of have agents secretly inserted within the command and line structures of the Imperial Military. So I can do that and work off of conflict between our characters once yours finds out that ISB placed an agent on your ship,

Or I can make my character into that NRI agent and be lead on the plan to get into the imperial ship. It all depends on what other interest we get in this RP.
