The Empire wants the fighting to stop. This territory, at least from what I've been told, was theirs. Feds seem to have a distaste for them, so do you, so do the rebels. Empire was much more fair and tactically skilled than the Federation has been thus far. At this point, the big guy over there and myself are likely going to be high-priority targets for the Feds. If you're looking to aid the Imperials, that puts us on the same side.
