No idea what we might have, or have access to in a timely fashion, that we could offer each faction.
Hmmm, I wonder if we could bluff, offering the identities of known imperial spies within each camp. It's possible that will definitely get imperial attention, which would give us the opportunity to capture some imperials for interrogation.
Another option would be to try and gain access to one of the bunkers (or the station) and see if we can't actually get some local intelligence.
