Beating up another realm is "equal", in that whatever you can do to those nobles they can hypothetically do to you. Sure, things like resources and abilities and location might differ, but the point is there is no disparity mechanically. For adventurers, there is mechanical disadvantage. That isn't exactly a bad thing since it does help drive home that nobles are greater than adventurers. I have nothing against being able to arrest an adventurer, but I don't exactly agree with beating them up. If an infiltrator stabs an adventurer that's ok since it's the same risk priests and other unitless nobles run. It just seems a bit harsh by game mechanics to allow any noble with a unit to at least wound any adventurer in the same region.
