That's awesome.
Lawspeaking allows you to form a village and create a village idol; which needs four deer antlers. They're hard to get.
When you have a village claim up, you can create banners to spread the claim and you need to keep making LP or the authority goes down and eventually the claim breaks.
You can create crossroads with a village claim, think of it like "travel to hearthfire" but it takes you to other places.
You can assign people as chieftains, and herdsmen and such.
