It would be rather interesting if nearby dungeons create a type of event where in mobs of that dungeon will make periodic trips to all nearby villages, and if you are on your claim, there will be a small timer on the top right, that says " time until dungeon invasion" or something like that.
If there is crops, they will eat some, and basically be an annoyance. If they eat crops off a claim, it will also create a scent. If you have walls, the beasts will damage 1/5 of them, and can even destroy them over time, but they will focus undamaged walls.
