What happens if someone claims the territory right next to mine?

@Peregrine @Magpie feel free to correct me if I'm way off the mark here.

@Tyrr We're probably going to discourage it to be fair regarding overlaps. It depends largely on the size of the pack. A full pack might be a little more aggressive in defending their buffer zone, whereas a smaller pack wouldn't even be there. The new territory claims are meant to emulate the way wolf packs work in the wild. Wolves have a "heart" that they spend most of their time in and defend fiercely, but the outer reaches of their territory are transient. On top of that, wolf packs in Yellowstone National Park actually have overlapping territories. Typically, wolf packs with overlapping outer boundaries actually avoid that area completely to minimize conflict, and if they do meet in the overlap, then there are usually disputes over food... but one pack doesn't invade the other pack's "heart" to try to drive them out or anything.

We haven't completely set out how territory claims work with the new system, this is all just how I understand it. For now, treat the inner claim as the "true" claim that your character is territorial about, and the outer claim as the buffer zone or "surrounding neutralish grounds". A wolf in the buffer zone may be treated stiffly or tensely by the pack, but probably not chased or directly threatened if they aren't being threatening themselves. Outside their claim, a wolf pack of 15 doesn't actually have the numbers to be territorial, so for example SB couldn't really show territoriality over Gyrfalcon's Keep or Wheeling Gull Isle, because it's way outside their claim. In order to dispute a pack's claim in those areas, SB would need to leave their lands completely undefended, and wolves just don't ever do that.

In summary: if two packs' outer zones overlap, wolves from the larger pack may be aggressive toward wolves from the opposing pack in the overlap but otherwise don't have the numbers to be territorial of entire adjacent territories, so a wolf from OS can't march into a pack territory in NWF, for example, and tell them to get lost because the inner claim, or true claim, is in a whole other area (and technically is miles away).
