I'm not sure how permanent portals work in Pathfinder, but a 3.5 edition book states that once created a portal can't be moved.
Here's the question: Does that mean the portal is fixed in the exact spot it was created forever or if it was part of a moving structure like a ship, flying castle, etc. it would move with the structure and not tear through walls and be left hanging in space?
In first and second edition portals moved with ships, insides wagons or whatever they were built as part of, I'm not clear if that is the case in Pathfinder.
