There are a lot of Amentan countries. Vanda Nossëo representatives are dispatched to all of them. These Elves (two with black hair, one with silver) take a shuttle down from the lightleaper to a country called Calado, and radio ahead to request permission to land at a elegant modern spaceport.
"Whole phrase is 'arbitrary deportation or forcible transfer of whole populations'. Deporting people who committed a crime or aren't citizens isn't relevantly arbitrary. Clearing out a conquered province for your people to live there would count, though. - if we'd gotten here forty years ago would you have wanted us to say to the Oahk Empire - 'that looks pretty ugly...it's legal locally? okay, I guess...'"
"Oh, we've been keeping the reds the hell out of the news at home, that would be a disaster, I guarantee you there'd be university student groups trying to sneak here to take reds home with them. There were journalists on the Rivikni thing but that's because we self-police really strongly on causing crimes here, and I think they're reporting it as some Rivikni eccentricity being appropriately handled. But to answer your question - if another murder came to our attention we'd forward you the evidence from conjuration and trust you to take it from there - you have a really good justice system, and I don't think I'm just jaded by wading through dysfunctional ones. The problem is gonna be when we run across a dead body and no local law to hand it off to. Honestly, if it were illegal to torture reds but the penalty were a week in prison we wouldn't have a leg to stand on, that's an extant system and we defer to those wherever they exist."
"We'll never make demands. We'll sometimes arrest murderers if the murder is obviously instigated by our presence and the local government can't or won't enforce the law. Joining is voluntary, spaceport's voluntary, you can tell us all to go away and we will. But 'aliens came to Amenta, people got murdered over it, their murderers got off' doesn't ring to me as 'made everything unambiguously better'."
