How could it possibly be too vague?That's too vague of a question to answer. It could be calling in a favor from the local spy guild that you won't be able to use later. It could be paying a large sum of money (large enough to actually matter). It could be a special mission to intercept a courier. It could be a complex skill challenge with a lot of RP and possible combat. Depending on the scenario it could be that many Bothans died to get the plans. Depends on what I'm trying to set up and what makes sense.
In the real world, when you kill someone's soldiers, they have fewer soldiers to field. That's literally the most basic possible bit of knowledge one can have: by removing something, there is less of it!
