Iron Fence

The Iron Fence is a humongous metal and wooden fence that separates the Feral Hills and Southern Steppe Fields from the Western United Pastures. It has many outposts alongside it for all three countries.

History
After the war between the Pastures, Feral Hills and the Southern Kingdom, borders were established and fences were built to indicate those. After more and more animals kept crossing the borders, though many outposts were established alongside the fence on either side of the border. The fence kept being made stronger and stronger to made sure no one could get out without permission. The fence eventually became known as the Iron Fence.
