When a TO is running, the realm running the TO is always the defender.
Only a region owner fighting as the Defender, can use the walls. Therefore, when an active TO is running, no one gets the walls.
One question regarding this matter of TO's and walls: is there any possible way to enter a region guarded by a garrison and start a TO (avoiding to engage in combat with the defenders), in order to refrain them from using the walls?
