Contour
or lakes 
and lockable Fort 
. The contour is erected in the valley by the players to protect their possessions from entering from the outside.
You can get inside the circuit with the permission of its owner or by destroying the fort. It is impossible to destroy the contour walls as long as there is a fort, after breaking it you can destroy the walls. In the contours of the players surround the quest locations, there are transferred gray cities in order to be able to safely go there to gain experience for the heroes or plunder resources.
The contour is being built only around its cities and mercenary camps. At first, no more than two cells away from the city, a wall is laid (a lake is digging). The wall (lake) building is paid - one element costs 50 gold. The object is being built on the map 24 hours, but this procedure can be accelerated by 30% for 35 coins. Similar rules for the demolition of walls (burying lakes) in the valley.
You can not close the contour of the fort, if there is no inside your city. It should be noted that neither the fort nor the camp of mercenaries are cities. Camps of mercenaries, trapped in the circuit will be automatically thrown out of its limits after about 4 hours.
