Imperial Paling

The Imperial Paling was a vast magical construct that formed an arcane barrier around the coastal parts of the former Rosen Empire. Apart from exceptional circumstances, the paling was impenetrable from the outside by either magical or mundane means. However, maintaining it came at a great magical cost. Furthermore, it could not be uninstalled in given places; the paling had to be active across the entire coast or not at all. Owing to the significant problems this presented for trade and movement across borders, as well as the magical resources required to maintain in, the paling was seldom deployed, and then mostly during wartime.

The Five Powers Treaty strictly prohibits the creation of a new paling anywhere that was formerly part of the Rosen Empire.

History
The paling was last used during the Great War.
