Khitan Fence

Description
This low fence is not designed to keep enemies out, but rather to provide defensive archers with a measure of cover between shots. Reinforced Stone is one of the hardest building materials that can be created in the Exiled Lands. Weapons barely chip it and even explosive powder is not enough to weaken it in a single blow. Siege weapons or divine intervention are really the only way to bring down walls this strong.
