I don't think we have to care about the local politics and arguably I think our employers would rather we do not. Broadly speaking I think there are two reasons why you would fork out money to hire twelve elves as a Kislevite notable:
- You want a foreign magic user to do something the native traditions cannot
- You need an elite force to handle something
- You want someone who does not care about local conflicts to handle something sensitive
There are a few assumptions here that I don't think are actually true.
Firstly, that point #3 will remain true for any meaningful length of time...it won't. Again, we're gonna live here, us seeming to care about local politics is even more inevitable than us actually caring. By the time five years have passed, #3 will just no longer be a factor. By that point people will have formed an opinion of us and our political beliefs even if they have no real data.
Secondly, that #3 would be an advantage. Honestly, being hired because we 'don't care about local politics' is a great way to get hired to either commit atrocities, piss off people we don't want to piss off (again, we intend to live here), or both. Like, if people are hiring us for Reason #3? We probably don't want to work for those people. There are exceptions, but it's not usually a good call.
Thirdly, the assumption that our mercenary group will remain only Fanriel and her Swordmasters for any extended period. I think us recruiting additional people is something we very much want and changes the calculus significantly.
On top of that Fanriel has no real reason to assume that whatever is going on here has national scale impacts for the whole of Kislev. I would be fine with walking away with our money, but if we must poke this I think asking is a lot less likely to endanger that pay out.
Curiosity is literally Fanriel's most notable trait, what got her exiled. I'm fine with taking the 'ask questions' route, but it wouldn't feel true to her character to not at least try and figure out what's up, IMO.
