Northland

The Northland (ノースランド, Nōsurando) is a country located on an island that orbits around Earth's moon. It was built by Master Chao prior to his death to be the ultimate training facility. Only the outer circle of it proved to be battle training, however, it has gravity 200x Earth's, making anyone who trains on it physically stronger just by standing on it. It has an atmosphere similar to Earth's.

Outer Circle
This part is a barren, desolate wasteland filled with battle robots that kill "anything with a pulse", according to Chao Jr, the grandson of Master Chao. They not only appear as robots, but in the forms of goblins and swarms of micro-bacterial robots that can posess objects. To get to the Inner Circle, one must either defeat all the robots or possess an A-Remote, a small box on a string that hide their signal from the bots.

Inner Circle
This part is a futuristic society filled with Martial Artist humans who have adapted to the gravitational conditions of this place. It is divided into five equal areas, the Wind Country, the Water Country, the Earth Country, the Fire Country and the Lightning Country. Each is ruled by one of the Five Elemental Kings.
