Yes. You can goto mountain pass or to a new territory.
I just have extra bags for the bldg tiles, so thats all I had meant. Thanks for answering about the enemy territories.
Does the same hold true after you defeat a territory and are not on your mtn pass? Can you go anywhere from the last point you were at, (the defeated territory empty space), as if you were on the mtn pass?
I forgot to include this second part in my original post.
