Guy trespasses on my land in order to leave a threatening runestone (IM COMING FOR YOU) and then I track him to his home. He's outside, I punch him to death. He has his keys on him, to his village, his leatherworking station to the south, his mine nearby, and his friend's village. His village is dead for his irresponsibility (and of course my general bloodlust) and his friends are being robbed for everything they're worth as I type this out, because I'm not a terribly nice guy.
Kids, read the damn stickies, don't carry your keys outside your village.
