I guess I should have used NESW for the map, I didn't really center it around compass directions haha. I just whipped it up quick to show to people since folks were getting restless about us not having anything built yet. The top is East, right is South, left is North, down is West.
Farmland doesn't really need to be on the deed, I have 180 tiles of farm we can fence off right near it.
Animal pen is nice to have on deed though, since it means the horses will be under deed law and someone can't smash a fence and run off with them.
As far as the double walls, I kinda wanted the walls on deed for two reasons: 1. it prevents decay, so less upkeep on the brick consuming walls. And 2. palisades on-deed can be controlled by the deed. Off-deed we would have to use gate houses, which iirc are much more vulnerable than palisade gates. Also, large carts can't be driven through gate houses.
The mine on-deed would take up a lot of space, just the entrance would need to be at least 4x3, possibly 5x3 or more depending how deep it ends up being just to get a good path down.
What I was thinking with the mine entrance off to the side would be maybe digging right into the cliff outside the deed (well, the cliff we've created lol) and then down and straight to make a little flat area a bit lower. Then to the left and right we could dig down, down, flat. Then turn back toward deed area with down, down flat. That would give us the initial slope from the tunnel + 5 more tiles of it. Think that would be enough to go under? If not maybe expand out another tile from the deed before turning. We could still have a 15x15 area under the deed mined out, the entrance would just be right off-deed. We could always expand the deed by 1 tile and make another wall layer all the way around right above the mine entrance with a third palisade gate if we wanted to. The ramp going to the deeded area under the town would be off-deed - would that be ok as long as we reinforced all the cave walls?
