Would it be a pre-existing world or a crafted world? If it was made by a powerful conjurer then maybe they would be using the energy from the barrier to create something else within it. They would also be leaving key things out like controlled weather or wind. 

Or maybe a place in another country that has an area that amplifies magic but the effect can only be achieved when conducting a large amount of energy like the barrier. 

I'm just throwing some ideas out. I like that it's a place that amplifies magic, but changes the rules. I guess what I'm asking is the world demonic looking? Does it look like a typical area like a country side or is it a desolate place?
