I built a fairly long tunnel system under Frya. It just a 3x3 tunnel, I tried my best to go around claimed land and got permission when possible. What are the rules when someone claims land above the tunnel(not knowing it is there), then digs down to it and starts building in it?

If another person hits your man-made tunnel, they are expected to close up the hole, and to change direction.

Also that would make a great ring road for a subway.

''fairly long'' isnt the correct word im afraid

Is this part of the tunnel system that has a station in Beorn?
