This kind of ties into a suggestion I have seen with true established bases. Perhaps a menu that can be brought up to show your clan’s areas in coordinates, OR, have a base signpost with a way to name that area that is claimed. Then, you can send thralls between those named areas.
Aside from thralls, perhaps a band of NPCs similar to the Purge that just fight things. Script out a path they follow. Maybe they have slaves or animals following them. They just walk through a terrain, or any area.
